Question 1Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which document is the primary source for the permissible exposure limits (PELs) enforced by OSHA for general industry air contaminants?

  1. 29 CFR 1910.1200 hazard communication standard
  2. 29 CFR 1910.1000 air contaminant tables Correct answer.
  3. 29 CFR 1910.146 permit-required confined space standard
  4. 29 CFR 1904 recordkeeping regulation

Explanation

The OSHA general industry air contaminant tables in 29 CFR 1910.1000 list enforceable permissible exposure limits for many substances. Other standards may require monitoring or communication but do not themselves establish the numeric PELs.

Question 2Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker is exposed to noise averaging 92 dBA over an 8-hour shift. Under OSHA requirements, what must the employer do first when the exposure exceeds 85 dBA?

  1. Replace all machinery with quieter models before the next shift
  2. Provide a hearing conservation program including audiometric testing Correct answer.
  3. Require immediate removal of the worker from the area
  4. Submit a written variance request to OSHA

Explanation

When noise exposure equals or exceeds the 85 dBA action level over 8 hours, the employer must implement a hearing conservation program with monitoring, audiometric testing, and training. Engineering controls are required at 90 dBA, but the first obligation triggered at the action level is the conservation program.

Question 3Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which type of respirator provides the highest assigned protection factor when properly fitted and used?

  1. Filtering facepiece N95 respirator
  2. Full-facepiece self-contained breathing apparatus in pressure-demand mode Correct answer.
  3. Loose-fitting powered air-purifying respirator with hood
  4. Half-mask air-purifying respirator with cartridges

Explanation

Pressure-demand full-facepiece SCBA carries one of the highest assigned protection factors because positive pressure inside the facepiece limits inward leakage. Air-purifying and loose-fitting devices generally have lower protection factors.

Question 4Safety, health, and environmental practices (content based on the ASP examination blueprint)

An employer uses a substance with an OSHA permissible exposure limit of 50 ppm. Air monitoring shows an 8-hour time-weighted average of 30 ppm. What does this result indicate?

  1. The PEL is not applicable because the average is below 50 ppm
  2. Monitoring must be repeated only if symptoms are reported
  3. Exposure exceeds the PEL and requires immediate respiratory protection
  4. Exposure is below the PEL but may still warrant controls if close to the limit Correct answer.

Explanation

A time-weighted average below the PEL indicates compliance with the limit for that period. However, exposures near the limit still merit attention because of variability and the need to maintain margins.

Question 5Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which hazard control is placed highest in the hierarchy of controls?

  1. Administrative controls such as job rotation
  2. Elimination of the hazard from the process Correct answer.
  3. Warning signs and training
  4. Personal protective equipment

Explanation

Elimination removes the hazard entirely and is the most effective control in the hierarchy. Administrative controls, PPE, and warnings rely on human behavior and residual hazard presence.

Question 6Safety, health, and environmental practices (content based on the ASP examination blueprint)

A confined space has an oxygen concentration of 17.5 percent. What is the significance of this reading?

  1. It is acceptable because it is above 16 percent
  2. It is normal and requires no action
  3. It is below the minimum acceptable oxygen level for entry Correct answer.
  4. It indicates an oxygen-enriched atmosphere

Explanation

Atmospheric oxygen below 19.5 percent is considered oxygen-deficient and unsafe for entry. A reading of 17.5 percent falls below that threshold and requires ventilation and reassessment before entry.

Question 7Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following best describes the purpose of a job hazard analysis?

  1. To document employee disciplinary actions
  2. To record the results of annual fire inspections
  3. To identify task steps and associated hazards before work begins Correct answer.
  4. To calculate workers' compensation premiums

Explanation

A job hazard analysis breaks a task into steps and identifies hazards and controls for each step before work is performed. It is a proactive planning tool rather than a recordkeeping or cost function.

Question 8Safety, health, and environmental practices (content based on the ASP examination blueprint)

A chemical has a flash point of 38 degrees Celsius and a boiling point of 95 degrees Celsius. How is it classified for flammability purposes?

  1. Combustible liquid
  2. Nonflammable liquid
  3. Oxidizing liquid
  4. Flammable liquid Correct answer.

Explanation

A liquid with a flash point at or below 60 degrees Celsius is generally classified as flammable. A flash point of 38 degrees Celsius places it in the flammable category.

Question 9Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which action best reduces the risk of musculoskeletal disorders in a manual material handling task?

  1. Providing back belts to all workers
  2. Increasing the weight of loads to reduce trip frequency
  3. Redesigning the task to reduce force and awkward postures Correct answer.
  4. Requiring workers to lift faster to reduce exposure time

Question 11Safety, health, and environmental practices (content based on the ASP examination blueprint)

A workplace has a spill of a corrosive liquid. Which immediate action should be taken first if trained responders are available?

  1. Flush the spill into the floor drain
  2. Neutralize the spill with a strong base
  3. Evacuate the immediate area and control access Correct answer.
  4. Wipe the spill with paper towels

Explanation

The first priority in a spill response is to protect people by evacuating and isolating the area. Cleanup or neutralization follows only after hazards are assessed and proper controls are in place.

Question 12Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which factor most strongly influences the severity of an electric shock?

  1. Length of the power cord
  2. Number of warning labels on the panel
  3. Color of the equipment enclosure
  4. Current magnitude and path through the body Correct answer.

Explanation

The magnitude of current and its pathway through the body determine the physiological effects of an electric shock. Voltage, duration, and body resistance also matter, but path and current are central.

Question 13Safety, health, and environmental practices (content based on the ASP examination blueprint)

What is the required minimum approach distance concept intended to prevent?

  1. Slips on wet floors
  2. Falls from ladders
  3. Noise exposure above 85 dBA
  4. Contact with energized electrical parts Correct answer.

Explanation

Minimum approach distances keep workers and equipment far enough from exposed energized parts to prevent arc flash and contact injuries. They are a fundamental electrical safety control.

Question 14Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which practice best protects workers from silica dust during concrete cutting?

  1. Working faster to shorten exposure time
  2. Using wet cutting methods with local exhaust ventilation Correct answer.
  3. Wearing cloth face coverings
  4. Sweeping dust with compressed air

Explanation

Wet cutting suppresses dust at the source, and local exhaust ventilation captures airborne particles. These engineering controls are more effective than respiratory protection alone.

Question 15Safety, health, and environmental practices (content based on the ASP examination blueprint)

What is the purpose of a hazard communication program?

  1. To guarantee that all chemicals are eliminated from the workplace
  2. To satisfy fire code inspection requirements
  3. To ensure workers receive information about chemical hazards and protections Correct answer.
  4. To replace engineering controls with labels

Explanation

Hazard communication ensures that workers are informed about chemical hazards through labels, safety data sheets, and training. It supports informed decisions about safe handling rather than eliminating chemicals.

Question 16Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which type of fire extinguisher is appropriate for a flammable liquid fire?

  1. Class B extinguisher Correct answer.
  2. Class K extinguisher
  3. Class D extinguisher
  4. Class A extinguisher

Explanation

Class B extinguishers are designed for flammable liquid and gas fires. Using a water-type Class A extinguisher on a liquid fire can spread the burning material.

Question 17Safety, health, and environmental practices (content based on the ASP examination blueprint)

A safety manager is selecting controls for a task with high exposure frequency and severe potential consequences. Which approach is most appropriate?

  1. Delay controls until an incident occurs
  2. Combine engineering controls with administrative measures and PPE Correct answer.
  3. Rely solely on training and warning signs
  4. Rely solely on PPE because it is inexpensive

Explanation

High-frequency, high-severity risks warrant layered controls that reduce the hazard at the source and provide backup protection. Combining engineering, administrative, and PPE measures provides defense in depth.

Question 18Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following is a leading indicator of safety performance?

  1. Recordable injury rate
  2. Number of safety observations completed Correct answer.
  3. Workers' compensation claims paid
  4. Lost-time injury count

Explanation

Leading indicators measure proactive activities that predict future performance, such as observations and training completion. Injury rates and claims are lagging indicators that reflect past events.

Question 19Safety, health, and environmental practices (content based on the ASP examination blueprint)

What is the primary purpose of an incident investigation?

  1. To determine whether disciplinary action is needed
  2. To assign blame to individual workers
  3. To identify root causes and prevent recurrence Correct answer.
  4. To satisfy insurance reporting only

Explanation

An effective investigation identifies contributing factors and root causes so that corrective actions can prevent similar events. Blame-focused investigations discourage reporting and miss systemic causes.

Question 20Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which element is essential for an effective emergency action plan?

  1. A list of employee performance ratings
  2. A schedule of production quotas
  3. A record of equipment maintenance costs
  4. Clearly defined evacuation routes and accounting procedures Correct answer.

Emergency action plans must specify evacuation routes, assembly points, and methods to account for personnel. These elements ensure orderly response and accountability during an emergency.

Question 21Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker must enter a permit-required confined space. Which condition must be verified before entry?

  1. Atmospheric testing confirms acceptable oxygen and contaminant levels Correct answer.
  2. The entrant has completed a full shift without breaks
  3. The space has been used previously without incident
  4. The entry occurs during daylight hours

Explanation

Atmospheric testing for oxygen, flammables, and toxic contaminants must confirm acceptable conditions before entry. Prior use or time of day does not substitute for testing.

Question 22Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following best describes the purpose of a safety data sheet?

  1. To provide detailed hazard, handling, and emergency information about a chemical Correct answer.
  2. To replace employee training requirements
  3. To certify that a chemical is safe for all uses
  4. To serve as a purchase order for the chemical

Explanation

Safety data sheets communicate hazards, safe handling practices, and emergency response information in a standardized format. They support, but do not replace, training and risk assessment.

Question 23Safety, health, and environmental practices (content based on the ASP examination blueprint)

A machine has an unguarded rotating shaft. Which control is most appropriate?

  1. Increase the shaft rotation speed
  2. Install a fixed guard that prevents contact with the shaft Correct answer.
  3. Post a warning sign near the shaft
  4. Require workers to wear loose clothing

Explanation

A fixed guard physically prevents contact with moving machine parts and is an engineering control. Warnings and administrative measures are less reliable than barriers.

Question 24Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following is a characteristic of an effective safety and health management system?

  1. Top management commitment with employee participation Correct answer.
  2. Incident reporting limited to serious injuries
  3. Safety responsibility assigned only to the safety officer
  4. Annual training as the sole control measure

Explanation

Effective safety management systems require visible leadership commitment and meaningful worker participation. Responsibility must be shared across the organization rather than isolated to one role.

Question 25Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker is exposed to a chemical with a ceiling limit. What does a ceiling limit represent?

  1. A concentration allowed only during maintenance
  2. An average exposure over an 8-hour shift
  3. A concentration that must not be exceeded at any time Correct answer.
  4. A short-term exposure limit averaged over 15 minutes

Explanation

A ceiling limit is an absolute maximum concentration that must never be exceeded during any part of the workday. It differs from time-weighted averages and short-term exposure limits.

Question 26Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which practice is the most reliable way to protect workers from exposure to airborne lead when engineering controls cannot reduce concentrations below the permissible exposure limit?

  1. Relying on natural ventilation through open windows
  2. Rotating workers so no one exceeds the limit
  3. Posting warning signs at the entrances to the work area
  4. Using approved respiratory protection with a written program Correct answer.

Explanation

When engineering and administrative controls cannot bring airborne contaminants below the permissible exposure limit, a written respiratory protection program with NIOSH-approved respirators must be implemented. The program includes fit testing, medical evaluation, training, and maintenance of the equipment.

Question 27Safety, health, and environmental practices (content based on the ASP examination blueprint)

What does the term 'permissible exposure limit' represent in occupational health?

  1. The concentration at which a chemical becomes immediately dangerous to life
  2. The amount of a substance that can be stored in a workplace
  3. The lowest concentration at which a chemical can be detected by odor
  4. The maximum airborne concentration a worker may be exposed to over a defined period Correct answer.

Explanation

A permissible exposure limit is a regulatory airborne concentration that must not be exceeded over a specified time period, such as an eight-hour shift. It is the benchmark against which exposure monitoring results are compared to determine whether controls are adequate.

Question 28Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker uses a portable ladder to reach an elevated work platform. Which practice should be followed to reduce fall risk?

  1. Standing on the top two rungs to reach higher
  2. Carrying tools in both hands while climbing
  3. Tying the ladder to the platform and maintaining three points of contact Correct answer.
  4. Leaning the ladder at a shallow angle to save space

Explanation

Securing the ladder prevents it from shifting, and maintaining three points of contact reduces the chance of losing balance while climbing. Tools should be carried in a belt or hoisted separately so hands remain free.

Question 29Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following is an example of a personal protective equipment item used to protect the eyes from flying particles?

  1. Safety goggles marked as meeting impact standards Correct answer.
  2. A face shield worn alone without spectacles
  3. A hard hat with a full brim
  4. A dust mask

Explanation

Safety goggles designed and marked for impact resistance provide a seal around the eyes and protect against flying particles. A face shield alone does not provide adequate primary eye protection against projectiles.

Question 30Safety, health, and environmental practices (content based on the ASP examination blueprint)

What is the primary purpose of conducting regular workplace safety inspections?

  1. To measure employee productivity
  2. To assign blame for recent injuries
  3. To identify hazards and verify controls before incidents occur Correct answer.
  4. To satisfy insurance paperwork requirements

Explanation

Inspections are proactive activities that detect unsafe conditions and practices so they can be corrected before harm occurs. They also verify that existing controls remain effective and in place.

Question 31Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following best describes the concept of a hierarchy of controls?

  1. An ordered approach that favors eliminating hazards before relying on protective equipment Correct answer.
  2. A ranking of hazards by their likelihood of causing injury
  3. A schedule for replacing worn tools
  4. A list of required training courses for each job

Explanation

The hierarchy of controls ranks strategies from most to least effective, beginning with elimination and substitution, then engineering controls, administrative controls, and finally personal protective equipment. The goal is to remove or reduce the hazard at its source whenever possible.

Question 32Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following is a common early sign of heat-related illness in a worker performing outdoor tasks?

  1. Loss of appetite over several weeks
  2. Aching joints in the knees
  3. Feeling cold and shivering
  4. Increased sweating with dizziness and headache Correct answer.

Explanation

Heat exhaustion commonly presents with heavy sweating, dizziness, headache, nausea, and weakness. Early recognition and prompt cooling prevent progression to heat stroke, which is a medical emergency.

Question 33Safety, health, and environmental practices (content based on the ASP examination blueprint)

What is the main objective of a hearing conservation program in a noisy workplace?

  1. To prevent occupational hearing loss through monitoring, protection, and training Correct answer.
  2. To measure worker satisfaction with noise levels
  3. To reduce the cost of hearing aids
  4. To eliminate all workplace noise

Explanation

A hearing conservation program combines noise monitoring, audiometric testing, hearing protection, and training to prevent noise-induced hearing loss. The goal is to keep worker exposure within safe limits rather than eliminate all noise.

Question 34Safety, health, and environmental practices (content based on the ASP examination blueprint)

An industrial hygienist is evaluating a solvent exposure and finds the eight-hour time-weighted average is 60 percent of the permissible exposure limit. What does this result indicate?

  1. The exposure is within the limit but should be monitored and controlled Correct answer.
  2. The exposure is safe and requires no further action
  3. The result cannot be interpreted without a ceiling limit
  4. The exposure is above the limit and requires immediate shutdown

Explanation

An exposure at 60 percent of the permissible exposure limit is below the regulatory maximum, but it still warrants continued monitoring and appropriate controls. Many programs use a fraction of the limit, such as half, as a trigger for additional sampling or corrective action.

Question 35Safety, health, and environmental practices (content based on the ASP examination blueprint)

A safety professional is developing a permit-required confined space program. Which element must be included to ensure safe entry?

  1. A written program with atmospheric testing and rescue provisions Correct answer.
  2. A verbal agreement among workers to follow safe practices
  3. A plan to rely on the local fire department as the only rescue option
  4. A requirement that entrants hold a commercial driver license

Explanation

A permit-required confined space program must be written and must include atmospheric testing, ventilation, attendant duties, entry permits, and arrangements for rescue. Rescue provisions must be established before entry begins so that a timely response is possible.

Question 36Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker reports numbness and tingling in the fingers after months of using a vibrating hand tool. Which condition is most consistent with this description?

  1. Contact dermatitis
  2. Carpal tunnel syndrome from repetitive keyboard use
  3. Occupational asthma
  4. Hand-arm vibration syndrome Correct answer.

Explanation

Prolonged exposure to hand-arm vibration can cause hand-arm vibration syndrome, characterized by numbness, tingling, and blanching of the fingers. Reducing exposure time and using anti-vibration tools are key controls.

Question 37Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which control measure is most effective at reducing noise exposure at the source in a manufacturing plant?

  1. Issuing earplugs to all workers
  2. Enclosing the noisy machine with sound-absorbing barriers Correct answer.
  3. Rotating workers between noisy and quiet tasks
  4. Posting a warning sign near the machine

Explanation

Engineering controls that enclose or isolate the noise source reduce sound at its origin and protect all workers in the area. Personal protective equipment and rotation are lower in the hierarchy because they depend on individual behavior and do not remove the hazard.

Question 38Safety, health, and environmental practices (content based on the ASP examination blueprint)

A safety manager is evaluating a chemical with a short-term exposure limit. What is the significance of this limit?

  1. It is the amount of chemical that can be stored on site
  2. It is the concentration at which a chemical ignites
  3. It represents the average exposure over a full work shift
  4. It applies to a brief exposure period and should not be exceeded at any time during that period Correct answer.

Explanation

A short-term exposure limit addresses brief, high-concentration exposures and specifies a maximum average over a short period, typically fifteen minutes. It complements the eight-hour limit and must not be exceeded during that short interval.

Question 39Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker in a hot environment becomes confused, stops sweating, and has hot, dry skin. What is the most appropriate immediate response?

  1. Give the worker cool water and return to work
  2. Have the worker rest briefly in the shade and continue the shift
  3. Apply warm blankets to raise body temperature
  4. Move the worker to a cool area and call emergency services Correct answer.

Explanation

Confusion, absence of sweating, and hot, dry skin suggest heat stroke, which is a life-threatening emergency. The worker must be cooled immediately and emergency medical services summoned without delay.

Question 40Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following is the best example of an engineering control for a dust-generating process?

  1. Limiting the time each worker spends at the task
  2. Requiring workers to wear respirators
  3. Training workers to stand upwind of the dust
  4. Installing a local exhaust ventilation system at the source Correct answer.

Explanation

Local exhaust ventilation captures dust at the point of generation and removes it before it enters the breathing zone. Engineering controls such as this rank above administrative controls and personal protective equipment in the hierarchy.

Question 41Safety, health, and environmental practices (content based on the ASP examination blueprint)

A safety professional is reviewing injury records and notices a cluster of lacerations during a specific shift. What is the most appropriate next step?

  1. Conduct a focused investigation of the tasks and conditions on that shift Correct answer.
  2. Reduce the reporting requirements for minor injuries
  3. Increase the number of posted warning signs
  4. Discipline the workers involved in the incidents

Explanation

A cluster of similar injuries signals a pattern that should be investigated to identify root causes such as equipment, training, or work practices. Targeting the specific shift allows corrective actions to address the actual contributing factors.

Question 42Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following best describes the purpose of an exposure control plan for bloodborne pathogens?

  1. To outline measures that reduce worker exposure to infectious materials Correct answer.
  2. To establish the company's vacation policy
  3. To document machine maintenance records
  4. To schedule annual fire drills

Explanation

An exposure control plan identifies tasks with potential exposure to blood or other potentially infectious materials and describes the controls, training, and vaccination provisions used to protect workers. It is a required written document for workplaces with occupational exposure risk.

Question 43Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker must handle a chemical that can be absorbed through intact skin. Which control measure is most important in addition to gloves?

  1. Increasing the ventilation rate only
  2. Posting the safety data sheet on a bulletin board
  3. Good housekeeping and prompt removal of contamination from skin Correct answer.
  4. Scheduling the task at the end of the shift

Explanation

When a substance can be absorbed through the skin, preventing skin contact is essential, including prompt washing and removal of contaminated clothing. Gloves alone may not be sufficient if contamination reaches other skin areas or if the glove is not resistant to the chemical.

Question 44Safety, health, and environmental practices (content based on the ASP examination blueprint)

Which of the following is an appropriate use of administrative controls in a safety program?

  1. Substituting a less hazardous chemical for a toxic one
  2. Providing respirators to all workers
  3. Rotating workers to limit the duration of a hazardous exposure Correct answer.
  4. Installing machine guards on moving parts

Explanation

Administrative controls change how work is organized, such as rotating workers or limiting exposure time, to reduce risk. They rank below elimination, substitution, and engineering controls because they do not remove the hazard.

Question 45Safety, health, and environmental practices (content based on the ASP examination blueprint)

A safety professional is evaluating whether a respirator program is effective. Which element is most critical to verify?

  1. That fit testing and medical evaluation have been completed for each user Correct answer.
  2. That respirators are worn only during inspections
  3. That respirators are stored in a locked cabinet
  4. That workers choose their own respirator model without assessment

Explanation

An effective respirator program requires medical evaluation, fit testing, training, and proper maintenance for each user. Fit testing confirms that the selected respirator seals properly, and medical evaluation confirms the worker can safely wear it.

Question 46Safety, health, and environmental practices (content based on the ASP examination blueprint)

A facility stores compressed gas cylinders. Which practice is most important to prevent a catastrophic release?

  1. Storing oxidizers and fuel gases together for convenience
  2. Storing cylinders upright and securing them to prevent falling Correct answer.
  3. Leaving valve protection caps off for quick access
  4. Storing cylinders near heat sources to keep them warm

Explanation

Cylinders must be kept upright and secured so they cannot fall and shear off the valve, which can cause a violent release of gas. Valve protection caps should remain in place during storage, and incompatible gases must be separated.

Question 47Safety, health, and environmental practices (content based on the ASP examination blueprint)

An analysis of exposure data shows that a control reduced airborne contaminant levels from 150 percent to 80 percent of the permissible exposure limit. Which conclusion is best supported?

  1. The data cannot be interpreted without additional sampling
  2. The control helped but exposure remains above the limit and further controls are required Correct answer.
  3. The control made the exposure worse
  4. The control is fully effective and no further action is needed

Explanation

Although the control lowered the concentration, the result remains above the permissible exposure limit, so additional controls are necessary. The hierarchy of controls should guide selection of stronger measures such as improved engineering controls.

Question 48Safety, health, and environmental practices (content based on the ASP examination blueprint)

A safety manager is designing a program to prevent musculoskeletal disorders in a warehouse. Which approach best reflects the hierarchy of controls?

  1. Conducting annual ergonomics awareness sessions
  2. Rotating workers among different lifting tasks
  3. Redesigning workstations and using mechanical lifts to reduce manual handling Correct answer.
  4. Providing back belts and training workers to lift carefully

Explanation

Redesigning workstations and adding mechanical lifting devices are engineering controls that eliminate or reduce the physical demand of the task. They rank above administrative measures such as rotation and training, and above personal equipment such as back belts.

Question 49Safety, health, and environmental practices (content based on the ASP examination blueprint)

A worker is overexposed to a chemical that is both a sensitizer and a carcinogen. Which combination of control strategies is most appropriate?

  1. Eliminate or substitute the chemical, then apply engineering controls and medical surveillance Correct answer.
  2. Use respirators as the primary control and continue current practices
  3. Rely on gloves alone and monitor symptoms
  4. Increase the work pace to finish the task more quickly

Explanation

For carcinogens and sensitizers, the most protective approach is to eliminate or substitute the substance, then use engineering controls and medical surveillance to verify protection. Personal protective equipment alone is insufficient because sensitization can occur at low exposure levels.

Question 50Safety, health, and environmental practices (content based on the ASP examination blueprint)

A safety professional is evaluating a ventilation system and finds that capture velocity at the hood is inadequate. What is the most likely consequence?

  1. The system consumes less energy with no effect on exposure
  2. The contaminant becomes less toxic
  3. Contaminants escape into the breathing zone of workers Correct answer.
  4. The exhaust fan runs more quietly

Explanation

Capture velocity is the speed of air at the hood needed to draw contaminants into the system. If it is too low, contaminants are not captured and can enter the worker's breathing zone, increasing exposure.
