Question 1Asbestos Abatement (Ohio Department of Health Asbestos Program)

Under the Ohio asbestos program, a contractor must notify the Ohio Department of Health before beginning a regulated asbestos abatement project. How many working days before the start date must the notification be received?

  1. At least 3 working days
  2. At least 1 working day
  3. At least 10 working days Correct answer.
  4. At least 20 working days

Explanation

Ohio requires that the abatement notification reach the Department of Health at least 10 working days before abatement begins. The notification window allows the state to schedule inspections and verify licensing before work starts. Starting earlier than the notice period is a violation even if all other paperwork is complete.

Question 2Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which federal regulation is the primary source of work practice standards for asbestos abatement in schools and public buildings that Ohio's program enforces?

  1. RCRA, 40 CFR Part 273
  2. NESHAP, 40 CFR Part 61 Subpart M Correct answer.
  3. CAA Title IV acid rain provisions
  4. TSCA Title I PCB rules, 40 CFR Part 761

Explanation

The National Emission Standards for Hazardous Air Pollutants, 40 CFR Part 61 Subpart M, sets the work practice standards for asbestos abatement, including emission controls and disposal. Ohio's asbestos rules align with these federal work practices. The other parts address solid waste, acid deposition, and PCBs rather than asbestos abatement.

Question 3Asbestos Abatement (Ohio Department of Health Asbestos Program)

An asbestos abatement worker must meet which minimum training requirement before performing abatement in Ohio?

  1. A forty-hour hazardous waste operations course alone
  2. A four-day accredited worker course with annual refresher Correct answer.
  3. A two-hour online awareness module only
  4. An eight-hour general construction safety course

Explanation

Abatement workers complete an accredited worker course of about four days covering abatement methods, safety, and regulations, and must take an annual refresher. Awareness training alone does not authorize hands-on abatement. General construction or HAZWOPER training does not substitute for asbestos worker certification.

Question 4Asbestos Abatement (Ohio Department of Health Asbestos Program)

During abatement inside a regulated work area, what is the purpose of maintaining the containment under negative pressure with HEPA-filtered exhaust?

  1. To speed drying of the removed material
  2. To reduce the noise level inside the containment
  3. To keep airborne fibers from escaping to occupied spaces Correct answer.
  4. To lower the oxygen level inside the work area

Explanation

Negative pressure ensures that air flows into the containment rather than out, so any released fibers are captured by HEPA filtration instead of migrating to occupied areas. This is a core engineering control required during abatement. Drying speed, noise, and oxygen levels are not the purpose of negative pressure.

Question 5Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker is removing intact vinyl floor tile that contains asbestos. Which removal method best reflects required work practices for this material?

  1. Break tiles into small pieces so they fit the disposal bag
  2. Dry-sweep debris into a pile for bagging
  3. Wet the material and pry tiles intact to minimize breakage Correct answer.
  4. Use a high-speed grinder to speed tile removal

Explanation

Non-friable material such as floor tile should be kept intact and wetted during removal to prevent fiber release. Breaking, grinding, or dry-sweeping creates dust and can render the material regulated. Intact removal also simplifies waste handling.

Question 6Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which personal protective equipment is standard for abatement workers inside a regulated work area?

  1. Cloth coveralls and a dust mask
  2. Street clothes with a hard hat
  3. Coveralls with no respiratory protection
  4. Disposable coveralls and a properly fitted respirator Correct answer.

Explanation

Workers inside containment wear disposable protective coveralls and a fitted respirator, typically a half-face or full-face air-purifying respirator with HEPA cartridges. Street clothes must not be worn into the work area because they can carry fibers out. Dust masks do not provide adequate protection.

Question 7Asbestos Abatement (Ohio Department of Health Asbestos Program)

How is asbestos-containing waste material typically packaged for transport off-site after abatement?

  1. Bundled with wire and left uncovered
  2. Placed in open dumpsters for sorting
  3. Sealed in leak-tight containers labeled as asbestos waste Correct answer.
  4. Stored in unlabeled cardboard boxes

Explanation

Waste must be sealed in leak-tight containers and labeled with the required asbestos warning so handlers and disposal sites can identify the hazard. Open, unlabeled, or uncovered packaging allows fiber release and violates transport requirements. Proper labeling also ensures the waste goes to an approved landfill.

Question 8Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which activity is generally outside the scope of work that requires an Ohio asbestos abatement contractor license?

  1. Routine custodial cleaning in a building with asbestos in good condition Correct answer.
  2. Enclosure of damaged asbestos surfacing material
  3. Removal of friable asbestos pipe insulation
  4. Encapsulation of sprayed-on asbestos fireproofing

Explanation

Routine custodial work in a building where asbestos remains undisturbed and in good condition is not abatement. Abatement means removal, enclosure, or encapsulation of asbestos-containing material. Those activities require a licensed contractor.

Question 9Asbestos Abatement (Ohio Department of Health Asbestos Program)

An inspector suspects that pipe insulation in an older building may contain asbestos. What is the correct way to confirm the asbestos content?

  1. Check whether the material crumbles when squeezed
  2. Test it with a handheld moisture meter
  3. Assume it contains asbestos based on the building's age
  4. Collect a bulk sample and analyze it at an accredited laboratory Correct answer.

Explanation

Asbestos content is confirmed only by laboratory analysis of a properly collected bulk sample using approved methods such as polarized light microscopy. Age, appearance, or field guesses are not evidence. Friability is a physical property, not proof of asbestos content.

Question 10Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which term describes asbestos-containing material that can be crumbled or reduced to powder by hand pressure?

  1. Friable Correct answer.
  2. Non-friable
  3. Encapsulated
  4. Bound

Explanation

Friable material can be crumbled, pulverized, or reduced to powder by hand pressure and therefore readily releases fibers. Non-friable material is more tightly bound, such as floor tile or roofing. Encapsulation is a control method, and bound describes matrix-bound material.

Question 11Asbestos Abatement (Ohio Department of Health Asbestos Program)

A supervisor is planning a large abatement project and must determine whether the project is a large or small project under Ohio rules. Which factor governs this classification?

  1. The amount of regulated asbestos-containing material to be removed Correct answer.
  2. The number of workers on the crew
  3. The square footage of the building
  4. The height of the building

Explanation

Project classification is based on the quantity of regulated asbestos-containing material involved, which determines the level of notification and work practice requirements. Crew size, building area, and building height do not define the project category. Accurate quantity estimates are therefore essential at planning.

Question 12Asbestos Abatement (Ohio Department of Health Asbestos Program)

After abatement is complete, what must happen before the containment is removed and the area is returned to normal use?

  1. A visual inspection and clearance air sampling by a qualified person Correct answer.
  2. A single walkthrough by the abatement crew
  3. A final sweeping with a broom
  4. A repainting of all surfaces

Explanation

Clearance requires a visual inspection confirming no visible residue and air sampling below the clearance threshold, performed by a qualified person independent of the abatement crew. Crew self-checks, dry sweeping, and cosmetic work do not establish clearance. Reoccupancy before clearance risks exposing occupants.

Question 13Asbestos Abatement (Ohio Department of Health Asbestos Program)

What is the primary function of a decontamination unit at an abatement site?

  1. To filter drinking water
  2. To prevent workers from carrying fibers out on clothing and equipment Correct answer.
  3. To store unused asbestos material
  4. To provide office space for supervisors

Explanation

The decontamination unit provides a clean-to-dirty sequence of rooms where workers remove contaminated clothing, shower, and change so fibers are not carried outside. It is a critical engineering control for protecting workers and occupants. Storage, water filtration, and office use are unrelated.

Question 14Asbestos Abatement (Ohio Department of Health Asbestos Program)

A building owner plans renovation that will disturb asbestos-containing ceiling tile. What must the owner ensure before work begins?

  1. That the tile is painted over and left in place
  2. That the maintenance staff handle it during normal hours
  3. That a licensed abatement contractor performs the regulated work and notification is filed Correct answer.
  4. That only the general contractor is informed

Explanation

Disturbing asbestos-containing material during renovation is regulated abatement, so a licensed contractor must perform it and the required notification must be submitted. Untrained maintenance staff, painting over, or informal notice do not satisfy the requirement. The owner remains responsible for compliance.

Question 15Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which practice is required when abatement waste is transported on public roads?

  1. Waste may be hauled in an open pickup bed
  2. Waste may be stored at the site indefinitely without cover
  3. Waste may be compacted on the roadside
  4. Waste containers must be secured and labeled with asbestos warning Correct answer.

Explanation

Transport requires leak-tight, labeled containers secured against spillage, and the waste must go to an approved disposal site. Open hauling, roadside compaction, and indefinite uncovered storage all risk fiber release and violate transport rules.

Question 16Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker's respirator must be fit-tested and the worker medically evaluated. Why is fit testing essential for asbestos abatement?

  1. A poor seal lets unfiltered air bypass the filter Correct answer.
  2. It measures the filter's micron rating
  3. It replaces the need for a HEPA vacuum
  4. It confirms the worker's lung capacity

Explanation

Fit testing verifies that the respirator seals to the face so inhaled air passes through the filter rather than leaking around the edges. A poor seal defeats the respirator regardless of filter rating. Fit testing does not measure filter efficiency, lung capacity, or cleaning equipment.

Question 17Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which situation would most likely require the abatement contractor to revise the notification submitted to the state?

  1. The start date is postponed by two weeks Correct answer.
  2. A worker calls in sick
  3. A ladder is replaced
  4. The weather turns rainy

Explanation

Changes to the start date or other key project information require an amended notification so the state can track the project. Routine personnel, weather, or equipment changes do not change the notification. Failing to amend a rescheduled start can result in the project being out of compliance.

Question 18Asbestos Abatement (Ohio Department of Health Asbestos Program)

Why are wet methods used during abatement of friable material?

  1. Moisture suppresses fiber release into the air Correct answer.
  2. Water sterilizes the material
  3. Water makes the material easier to burn
  4. Water dissolves asbestos fibers

Explanation

Wetting friable material keeps fibers bound and reduces airborne release during removal and handling. Asbestos fibers are not dissolved or sterilized by water, and burning is not part of abatement. Wet methods are a fundamental dust-suppression control.

Question 19Asbestos Abatement (Ohio Department of Health Asbestos Program)

A supervisor observes a worker dry-sweeping debris inside containment. What is the appropriate corrective action?

  1. Allow it because the containment is under negative pressure
  2. Stop the activity and require wet cleaning or HEPA vacuuming Correct answer.
  3. Allow it if the worker wears a respirator
  4. Allow it only at the end of the shift

Explanation

Dry sweeping is prohibited because it suspends fibers, and negative pressure or respirators do not make it acceptable. The supervisor must stop the activity and direct wet methods or HEPA vacuuming. Allowing it under any condition creates an unnecessary release.

Question 20Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which document typically must be posted or available at the abatement site to demonstrate compliance?

  1. The workers' personal vehicle registrations
  2. The abatement notification and contractor license information Correct answer.
  3. The supplier invoice for paint
  4. The building's property tax records

Explanation

Site records should include the notification confirmation and proof of contractor and worker certification so inspectors can verify compliance quickly. Property tax records, vehicle registrations, and paint invoices have no bearing on asbestos compliance. Keeping these records on site is a standard compliance practice.

Question 21Asbestos Abatement (Ohio Department of Health Asbestos Program)

An abatement contractor plans to remove approximately 300 linear feet of asbestos-containing pipe insulation. Which statement best describes the regulatory treatment of this work?

  1. It requires only a verbal notice to the building owner
  2. It is exempt because pipe insulation is always non-friable
  3. It is regulated abatement requiring notification, licensing, and work practice controls Correct answer.
  4. It may be done by maintenance staff without certification

Explanation

Pipe insulation is typically friable and its removal is regulated abatement, requiring notification, licensed contractors and certified workers, and work practice controls. It is not exempt, and verbal owner notice or uncertified maintenance staff do not satisfy the rules. Quantity and material type both point to a regulated project.

Question 22Asbestos Abatement (Ohio Department of Health Asbestos Program)

A building owner argues that because the asbestos-containing material will be enclosed rather than removed, no licensed contractor is needed. How should the contractor respond?

  1. Enclosure requires only a building permit
  2. Enclosure may be done by any certified inspector
  3. Enclosure is exempt because no material leaves the building
  4. Enclosure is a defined abatement activity and requires a licensed contractor Correct answer.

Explanation

Ohio defines abatement to include enclosure and encapsulation as well as removal, so a licensed contractor is required. The fact that no material leaves the site does not create an exemption. A building permit or inspector certification does not authorize abatement work.

Question 23Asbestos Abatement (Ohio Department of Health Asbestos Program)

During clearance, air sampling results come back above the clearance threshold. What is the most appropriate next step?

  1. Add a second layer of poly and reoccupy
  2. Reclean the work area and repeat clearance sampling Correct answer.
  3. Ignore the result because the visual inspection passed
  4. Remove the containment and reoccupy immediately

Explanation

Failed clearance requires recleaning with wet methods and HEPA vacuuming followed by repeat sampling until results are below the threshold. Removing containment or reoccupying risks occupant exposure. A passing visual inspection alone does not establish clearance.

Question 24Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker removes a respirator inside the dirty room of the decontamination unit before showering. Why is this a compliance problem?

  1. Respirators must be removed outdoors
  2. Respirators should never be removed during a project
  3. Respirator removal belongs in the clean room after decontamination Correct answer.
  4. Respirators must be removed in the work area

Explanation

The decontamination sequence requires workers to keep respiratory protection on until they have passed through decontamination and reached the clean room. Removing it in the dirty room exposes the worker to residual contamination. Respirators are removed in the clean area, not outdoors or inside the work area.

Question 25Asbestos Abatement (Ohio Department of Health Asbestos Program)

A contractor discovers that the quantity of regulated material is larger than reported in the notification. What is the correct action?

  1. Reduce the scope to match the original notification
  2. Submit an amended notification reflecting the revised quantity Correct answer.
  3. Proceed because the original notification was filed
  4. Stop work permanently and abandon the project

Explanation

Material changes to project information, including the quantity of regulated material, require an amended notification. Proceeding on the original filing leaves the project out of compliance. Abandoning the project or artificially cutting scope does not correct the record.

Question 26Asbestos Abatement (Ohio Department of Health Asbestos Program)

Under Ohio's asbestos program, which worker credential is required before an individual may perform abatement work inside a regulated work area?

  1. A lead-safe renovator certification issued by the state
  2. A current Ohio asbestos abatement worker certificate issued through the state program Correct answer.
  3. A general construction license issued by the local building department
  4. A hazardous waste transporter permit issued by Ohio EPA

Explanation

Ohio requires individuals who disturb asbestos-containing material during abatement to hold a valid state-issued abatement worker certificate, obtained after approved training and application through the Ohio Department of Health asbestos program. Construction licenses, waste transporter permits, and lead certifications do not authorize asbestos abatement work.

Question 27Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which individual is responsible for ensuring that abatement work practices, worker protection, and waste handling on an Ohio abatement project follow the required regulations?

  1. The building's insurance adjuster
  2. The building owner's real estate agent
  3. The certified abatement contractor supervising the project Correct answer.
  4. The waste landfill operator

Explanation

The licensed abatement contractor is accountable for on-site compliance, including work practices, worker protection, and waste handling. Other parties may have roles, but the contractor bears the regulatory responsibility for how the abatement is conducted.

Question 28Asbestos Abatement (Ohio Department of Health Asbestos Program)

What does the term 'regulated asbestos-containing material' (RACM) specifically identify in Ohio abatement work?

  1. Asbestos material in a form or condition that is subject to the strictest handling and disposal requirements Correct answer.
  2. Any material that contains detectable asbestos regardless of its condition
  3. Material that is installed in public buildings only
  4. Only material that has already been crumbled to powder by hand pressure

Explanation

RACM is a regulatory category covering asbestos-containing material that is friable or that will be disturbed in a way likely to release fibers, which triggers the most protective handling, packaging, and disposal requirements. It is not simply any material with detectable asbestos, nor is it limited to public buildings.

Question 29Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which condition most accurately describes 'friable' asbestos-containing material?

  1. Material that is installed only above ceilings
  2. Material that has been painted or otherwise sealed on all surfaces
  3. Material that is bonded in a rigid matrix and cannot release fibers
  4. Material that can be crumbled, pulverized, or reduced to powder by hand pressure when dry Correct answer.

Explanation

Friability refers to whether the material can be crumbled or reduced to powder by hand pressure when dry, which indicates a high potential for fiber release. Rigidly bonded or sealed material is generally nonfriable unless it is damaged or later disturbed.

Question 30Asbestos Abatement (Ohio Department of Health Asbestos Program)

Why must abatement workers avoid dry sweeping or dry shoveling debris inside a containment?

  1. Dry methods damage the plastic sheathing used to build the containment
  2. Dry methods are prohibited only when the building is occupied
  3. Dry methods suspend settled fibers into the air and increase worker and area contamination Correct answer.
  4. Dry methods are slower than wet methods and increase labor costs

Explanation

Dry sweeping and shoveling re-entrain settled asbestos fibers into the air, raising exposure and spreading contamination. Wet methods and HEPA vacuuming keep fibers from becoming airborne and are required work practices.

Question 31Asbestos Abatement (Ohio Department of Health Asbestos Program)

What is the purpose of a negative air pressure system in a regulated abatement work area?

  1. To cool the work area for worker comfort during summer projects
  2. To keep the work area under lower pressure so air flows inward and fibers do not escape Correct answer.
  3. To supply clean breathing air directly to each worker's respirator
  4. To dry wet material faster before packaging

Explanation

Negative pressure machines with HEPA filtration exhaust air from the containment, keeping it at lower pressure than surrounding spaces so that any leakage moves inward rather than releasing fibers to occupied areas. They do not supply breathing air or dry material.

Question 32Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which federal agency's asbestos regulations for construction work are commonly referenced alongside Ohio's abatement requirements for worker protection?

  1. Federal Aviation Administration (FAA)
  2. Federal Communications Commission (FCC)
  3. Occupational Safety and Health Administration (OSHA) Correct answer.
  4. Securities and Exchange Commission (SEC)

Explanation

OSHA's asbestos standards for construction and general industry set worker protection requirements such as exposure limits, respirators, and training that apply alongside Ohio's abatement program rules. The other agencies have no role in asbestos worker protection.

Question 33Asbestos Abatement (Ohio Department of Health Asbestos Program)

Which record must an Ohio-certified abatement worker be able to produce to demonstrate current authorization to work?

  1. A valid state-issued abatement worker certificate Correct answer.
  2. A notarized letter from the building owner
  3. A high school diploma
  4. A driver's license

Explanation

The state-issued abatement worker certificate is the credential that shows an individual is currently authorized to perform abatement work. Diplomas, driver's licenses, and owner letters do not establish abatement qualifications.

Question 34Asbestos Abatement (Ohio Department of Health Asbestos Program)

A contractor is preparing to remove asbestos-containing boiler insulation and wants to use glovebags on vertical pipe runs. Which condition must be met for glovebag work to be acceptable?

  1. The material must be dry so it falls into the bag easily
  2. The material must be handled wet and the bag must remain sealed until waste is packaged Correct answer.
  3. The bag may be opened freely as long as workers wear respirators
  4. Glovebags may be used only on horizontal pipes

Explanation

Glovebag techniques require wetting the material and keeping the bag sealed until the waste is properly packaged so fibers are not released. Opening bags freely or working dry defeats the containment purpose, and orientation is not the limiting factor.

Question 35Asbestos Abatement (Ohio Department of Health Asbestos Program)

A project involves removing 180 linear feet of asbestos-containing pipe insulation that is friable. How should this quantity most likely be classified for Ohio notification purposes?

  1. As a small project because it is below the threshold for large projects Correct answer.
  2. As a large project because friable pipe insulation over the threshold is regulated
  3. As exempt because pipe insulation is nonfriable
  4. As an emergency project because pipe insulation is involved

Explanation

Ohio distinguishes large and small projects by the amount of regulated material involved; friable pipe insulation measured in linear feet below the large-project threshold is notified as a small project. Emergency classification applies to unexpected events, and friable pipe insulation is not exempt.

Question 36Asbestos Abatement (Ohio Department of Health Asbestos Program)

During a pre-abatement inspection, an inspector needs to determine whether sprayed-on ceiling material contains asbestos. What is the appropriate approach?

  1. Collect a representative bulk sample and have it analyzed by an accredited laboratory Correct answer.
  2. Assume it contains asbestos because of its age and texture
  3. Test it with a handheld moisture meter
  4. Ask the building custodian whether it contains asbestos

Explanation

Confirmation requires representative bulk sampling analyzed by an accredited laboratory using approved methods such as polarized light microscopy. Assumptions, moisture readings, and verbal reports are not valid determinations.

Question 37Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker inside containment reports that their respirator seal feels loose after sweating. What is the correct action?

  1. Leave the work area through the decontamination unit and reseal or replace the respirator before returning Correct answer.
  2. Tighten the straps repeatedly while continuing to work
  3. Continue working and report the issue at the end of the shift
  4. Remove the respirator briefly inside containment to cool off

Explanation

A compromised seal means the respirator is no longer providing protection, so the worker must leave the work area through proper decontamination and correct the fit before re-entering. Adjusting repeatedly, removing the respirator inside containment, or waiting until shift end all leave the worker unprotected.

Question 38Asbestos Abatement (Ohio Department of Health Asbestos Program)

An Ohio renovation involves only Category I asbestos-containing floor tile, with no demolition or other RACM work. A contractor uses wet scraping that keeps the tile intact and nonfriable. Which statement best describes the notification obligation under Ohio's RACM renovation rules?

  1. Notification is unnecessary because floor tile is nonfriable Correct answer.
  2. Notification is required only if the building is a school
  3. Notification may be submitted after the project is finished
  4. The contractor must still submit the required notification to the state before work begins

Explanation

Under the stated conditions, the floor tile remains nonfriable Category I material and is not regulated asbestos-containing material (RACM). Ohio's RACM renovation-notification requirement therefore is not triggered by this work. This conclusion is specific to the described renovation; demolition, other RACM or methods that make the tile regulated can change the obligation.

Question 39Asbestos Abatement (Ohio Department of Health Asbestos Program)

A supervisor notices that the plastic sheathing on one wall of the containment has torn, creating an opening to an occupied hallway. What is the most appropriate immediate response?

  1. Increase the number of workers to finish faster
  2. Open windows in the hallway to dilute any fibers
  3. Stop work in that area, repair the breach, and clean up any contamination before resuming Correct answer.
  4. Continue work and repair the sheathing at the end of the day

Explanation

A breach in containment allows fibers to escape, so work in the affected area must stop until the barrier is repaired and any contamination is cleaned up. Delaying repair, adding workers, or diluting with hallway air does not restore containment.

Question 40Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker must exit the regulated work area at the end of the shift. Which sequence best reflects proper decontamination?

  1. Shower first, then remove contaminated clothing in the clean room
  2. Remove the respirator in the equipment room, then walk directly to the clean room
  3. Remove contaminated outer clothing in the dirty room, shower, then put on street clothes in the clean room Correct answer.
  4. Vacuum street clothes with a HEPA vacuum in the dirty room and exit

Explanation

The decontamination sequence moves from the dirty room, where contaminated outer clothing is removed, through a shower, into the clean room where street clothes are put on. Showering before removing contaminated clothing or skipping the shower defeats the purpose of the unit.

Question 41Asbestos Abatement (Ohio Department of Health Asbestos Program)

A contractor is storing asbestos waste bags on site before transport. Which practice best prevents fiber release?

  1. Keep bags sealed, labeled, and stored in a controlled area away from traffic Correct answer.
  2. Compress bags to reduce volume before sealing
  3. Stack open bags near a loading dock to speed pickup
  4. Store bags outdoors uncovered to allow drying

Explanation

Waste must remain sealed and labeled and be stored in a controlled area so bags are not damaged or opened before transport. Open, uncovered, or compressed bags risk releasing fibers and are not acceptable handling practices.

Question 42Asbestos Abatement (Ohio Department of Health Asbestos Program)

A building owner plans to demolish a structure that contains asbestos-containing material. What should the owner do before demolition begins?

  1. Proceed with demolition and bury the debris on site
  2. Rely on the demolition contractor to identify asbestos during demolition
  3. Have the material identified and removed by a certified contractor before demolition Correct answer.
  4. Spray water on the building and demolish it without further action

Explanation

Asbestos-containing material must be identified and removed before demolition so that fibers are not released during the demolition process. Burying debris, relying on identification during demolition, or simply wetting the structure does not satisfy the requirement.

Question 43Asbestos Abatement (Ohio Department of Health Asbestos Program)

A contractor discovers during abatement that the quantity of regulated material is substantially greater than what was described in the notification. What is the most appropriate action?

  1. Continue working and note the discrepancy in the final report
  2. Notify only the building owner and no one else
  3. Reduce the reported quantity to match the original notification
  4. Stop work as needed and submit an amended notification to the state before continuing Correct answer.

Explanation

When the scope of a project changes materially, the contractor must amend the notification so the state has accurate information before work continues. Recording the discrepancy later, altering figures, or notifying only the owner does not satisfy the notification requirement.

Question 44Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker's respirator must be fit-tested, and the worker must be medically evaluated. Why is fit testing essential for asbestos abatement?

  1. Fit testing replaces the need for medical evaluation
  2. Fit testing measures the filter's particle removal efficiency
  3. Fit testing confirms the worker can lift heavy debris
  4. A poor seal lets airborne fibers bypass the filter and reach the worker's breathing zone Correct answer.

Explanation

Fit testing verifies that the respirator seals against the worker's face so air enters through the filter rather than leaking around the edges. It does not measure filter efficiency, replace medical evaluation, or assess physical strength.

Question 45Asbestos Abatement (Ohio Department of Health Asbestos Program)

During clearance air sampling after abatement, results exceed the clearance threshold. What is the most appropriate next step?

  1. Remove the containment immediately to improve ventilation
  2. Increase the negative air pressure and release the space without resampling
  3. Re-clean the work area and repeat clearance sampling before releasing the space Correct answer.
  4. Release the space because the abatement work itself is complete

Explanation

Clearance is not achieved until sampling results meet the threshold, so the area must be recleaned and resampled. Releasing the space, resampling without cleaning, or removing containment prematurely can expose occupants to residual fibers.

Question 46Asbestos Abatement (Ohio Department of Health Asbestos Program)

A supervisor observes a worker removing a respirator inside the dirty room of the decontamination unit before showering. Why is this a compliance concern?

  1. The dirty room is contaminated, so removing the respirator there allows fiber inhalation Correct answer.
  2. Respirators must be removed only in the equipment room
  3. Respirators must be removed only after the worker has changed into street clothes
  4. The dirty room is too warm for respirator use

Explanation

The dirty room contains contaminated clothing and equipment, so the respirator must remain in place until the worker has passed through decontamination. Removing it there exposes the worker to airborne fibers. Temperature and equipment-room practices are not the basis for the requirement.

Question 47Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker inside containment develops dizziness and shortness of breath while wearing a tight-fitting respirator. What is the most appropriate response?

  1. Ignore the symptoms because they are common at the start of a shift
  2. Tell the worker to loosen the straps and keep working
  3. Have the worker remove the respirator inside containment and rest
  4. Escort the worker out through decontamination and seek medical evaluation Correct answer.

Explanation

Symptoms such as dizziness or breathing difficulty may indicate a medical problem or respirator issue and require the worker to leave the work area through decontamination and receive medical evaluation. Loosening straps, removing the respirator inside containment, or ignoring symptoms endangers the worker.

Question 48Asbestos Abatement (Ohio Department of Health Asbestos Program)

An owner argues that because asbestos-containing material will be enclosed rather than removed, no licensed abatement contractor is needed. How should the contractor respond?

  1. Enclosure is allowed only if the owner performs the work personally
  2. Enclosure requires only a building permit
  3. Enclosure of regulated material is an abatement activity that requires a licensed contractor and proper notification Correct answer.
  4. Enclosure is exempt because the material remains in place

Explanation

Enclosure is one of the recognized abatement methods, and performing it on regulated asbestos-containing material requires a licensed contractor and the applicable notification. The fact that material remains in place does not create an exemption, and a building permit alone is insufficient.

Question 49Asbestos Abatement (Ohio Department of Health Asbestos Program)

A contractor is planning abatement in a hospital wing that must remain partially operational. Which planning consideration is most critical to prevent contaminating the occupied area?

  1. Using scented air fresheners in the hallway
  2. Scheduling work only at night to avoid contact with patients
  3. Isolating the work area with critical barriers and maintaining negative pressure relative to occupied spaces Correct answer.
  4. Increasing the number of waste bags used per shift

Explanation

Critical barriers and sustained negative pressure keep the work area isolated so air flows inward and fibers cannot migrate into occupied hospital spaces. Night scheduling, bag counts, and air fresheners do not provide containment.

Question 50Asbestos Abatement (Ohio Department of Health Asbestos Program)

A worker finds that a HEPA vacuum used inside containment is not retaining particles and appears damaged. What is the most appropriate action?

  1. Continue using the vacuum but run it at lower power
  2. Seal the vacuum in a waste bag and keep using it
  3. Use the damaged vacuum only for large debris
