ASP Domain 6: Industrial Hygiene and Occupational Health
Domain 6 is 12% of the ASP, number 3 of 9 domains by weight. PassCited has 59 questions for it.
BCSP's ASP11 Examination Blueprint, V.2024.04.24 (effective Sept 1, 2025) weights Industrial Hygiene and Occupational Health at 12% of the ASP, a 5-hour exam. Give it study time in proportion to its weight.

Question 1
A plant uses forklift operators who move constantly between loud stamping areas and quiet warehouse zones, so sound levels vary significantly through the shift. The safety professional is deciding how to conduct noise monitoring for these workers. Which approach is consistent with the standard?
Show answer and source
Answer: C. Use representative personal sampling unless the employer can show that area sampling produces equivalent results
Where high worker mobility or significant variations in sound level make area monitoring generally inappropriate, representative personal sampling is required unless area sampling can be shown to give equivalent results. The other options contradict this requirement.
Answer C rests on
29 CFR 1910.95(d)(1)(ii)(opens ecfr.gov in a new tab)“Where circumstances such as high worker mobility, significant variations in sound level, or a significant component of impulse noise make area monitoring generally inappropriate, the employer shall use representative personal sampling to comply with the monitoring requirements of this paragraph unless the employer can show that area sampling produces equivalent results.”
Question 2
During a shift, a worker wearing a cartridge respirator in a solvent-use area notices that breathing has become noticeably harder. The worker tells the supervisor. According to the standard, what must the employer do before the worker returns to the work area?
Show answer and source
Answer: A. Replace or repair the respirator
A change in breathing resistance requires the employer to replace or repair the respirator before the employee returns to the work area. Waiting or reducing exposure time does not satisfy this requirement.
Answer A rests on
29 CFR 1910.134(g)(2)(iii)(opens ecfr.gov in a new tab)“If the employee detects vapor or gas breakthrough, changes in breathing resistance, or leakage of the facepiece, the employer must replace or repair the respirator before allowing the employee to return to the work area.”
Question 3
A clinic's bloodborne pathogens training for a phlebotomist was completed on March 10 of last year. In January of this year, the clinic introduced a new safety-engineered blood collection device that changes how the phlebotomist performs venipuncture and handles sharps. It is now February 15 of this year, and the phlebotomist has not yet used the new device. Which action does the standard require?
Show answer and source
Answer: C. Provide additional training addressing the new exposures created by the new device, even though the annual retraining date has not yet arrived
The new device modifies the employee's tasks and procedures and affects occupational exposure, so additional training is required when the change occurs, and it may be limited to the new exposures. Waiting for the annual date is wrong because the standard separately requires added training when procedures change.
Answer C rests on
29 CFR 1910.1030(g)(2)(v)(opens ecfr.gov in a new tab)“Employers shall provide additional training when changes such as modification of tasks or procedures or institution of new tasks or procedures affect the employee's occupational exposure. The additional training may be limited to addressing the new exposures created.”
