OH Asbestos Abatement flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

ODH Asbestos Program

Ohio Department of Health office that licenses asbestos abatement contractors, workers, supervisors, and air quality technicians, and enforces Ohio Administrative Code Chapter 3701-34 requirements.

Regulated asbestos-containing material

Material containing more than 1 percent asbestos that is friable or will be crumbled, pulverized, or reduced to powder during handling, demolition, or renovation, and is therefore subject to abatement rules.

Abatement notification deadline

The licensed contractor must submit written notification to ODH at least 10 working days before starting abatement; emergency abatement must be reported within 24 hours of the emergency.

Single-family residence exemption

A private residence occupied by its owner is generally exempt from contractor licensing and notification, but demolition and renovation emission and waste-disposal rules still apply.

Friable material

Asbestos-containing material that can be crumbled, pulverized, or reduced to powder by hand pressure when dry, making it more likely to release airborne fibers.

Homogeneous area

Surfacing, thermal system insulation, or other material that is uniform in color, texture, and date of application, and can be represented by one set of bulk samples.

Bulk sample analysis

Laboratory analysis of material samples by polarized light microscopy or transmission electron microscopy to determine asbestos type and percentage; results must come from an accredited lab.

OSHA permissible exposure limit

The 8-hour time-weighted average exposure limit for asbestos is 0.1 fibers per cubic centimeter, with a 30-minute excursion limit of 1.0 fiber per cubic centimeter.

Clearance air limit

Final clearance requires visual cleanliness plus air sampling at or below 0.01 fibers per cubic centimeter by PCM, or 70 structures per square millimeter by TEM.

Negative pressure enclosure

Containment using HEPA-filtered exhaust to maintain lower pressure inside the work area, preventing fiber migration to occupied spaces outside the regulated area.

Decontamination unit

Sequence of clean room, shower, and equipment room that workers pass through when entering and leaving the regulated area to prevent fiber spread.

Critical barrier

Plastic sheeting sealed over openings, vents, and surfaces in the work area to isolate the abatement zone and protect surfaces that are not being abated.

Wet methods

Work practice of wetting asbestos-containing material before and during removal to suppress fiber release, supplemented by HEPA vacuuming rather than dry sweeping.

Leak-tight waste container

Bag or wrap used for asbestos debris that is sealed and labeled with the OSHA warning and material identity before transport to an approved landfill.

Project supervisor duties

Daily on-site supervision of abatement, verification of worker certification, maintenance of containment integrity, and confirmation of visual cleanliness before clearance.

Air quality technician

Certified individual who collects personal and area air samples, including clearance samples, and ensures sampling and analysis follow accepted methods.

Abatement worker training hours

Initial abatement worker training requires at least 32 hours including hands-on exercises, with annual refresher training to maintain certification.

Supervisor training hours

Initial project supervisor and contractor training require at least 40 hours, followed by annual refresher training to keep certification current.

Inspector training hours

Asbestos hazard evaluation specialist training requires at least 24 hours of initial instruction, with annual refresher training to maintain the credential.

Certification renewal

Certification is maintained by completing required refresher training, submitting a renewal application to ODH, and paying the applicable fee before expiration.

License suspension or revocation

ODH may suspend, revoke, or deny a license for unlicensed work, falsified records, or failure to follow required work practice standards.

Project records retention

Contractors must retain notification copies, inspection reports, abatement plans, air monitoring results, and waste manifests for at least three years for ODH review.

Abatement work plan

Written project design identifying scope, removal methods, containment, worker protection, air monitoring, and waste handling before abatement begins.

Presumed asbestos-containing material

Material that must be treated as asbestos-containing until sampling by an accredited inspector demonstrates asbestos content of 1 percent or less.

Respirator fit testing

Required annual test confirming a respirator seals properly on the wearer; medical evaluation and training are also required before respirator use.

HEPA vacuum

Vacuum equipped with a high-efficiency particulate air filter used for cleanup of asbestos debris instead of dry sweeping or compressed air.

Waste shipment record

Documentation tracking asbestos waste from the project site to an approved landfill, retained with project records and available for inspection.

Visual inspection

Pre-clearance check by the project supervisor confirming no visible dust or debris remains in the regulated area before air sampling begins.

Emergency abatement

Abatement needed to address a sudden, unexpected release or imminent hazard; notification to ODH is due within 24 hours of the emergency.

Contractor licensing

Ohio requires abatement contractors to hold an ODH license and to ensure only certified workers and supervisors perform abatement activities.

Air monitoring comparison

Personal air samples are compared to the OSHA 8-hour TWA PEL of 0.1 f/cm3 and the 30-minute excursion limit of 1.0 f/cm3 to evaluate exposure.

Asbestos-containing material threshold

Material is considered asbestos-containing when laboratory analysis reports more than 1 percent asbestos by weight, triggering applicable handling requirements.
