CAOHC Hearing Conservation Programs 2 — Questions and Answers
Question 1: What are the essential components of an OSHA-compliant hearing conservation program?
- Noise monitoring, audiometric testing, hearing protectors, training, and recordkeeping (Correct answer)
- Only annual audiometric testing and hearing protector distribution
- Engineering noise controls and administrative scheduling only
- Employee health questionnaires and annual physical exams
Correct answer: Noise monitoring, audiometric testing, hearing protectors, training, and recordkeeping
OSHA requires five key components: noise monitoring, audiometric testing, hearing protectors, annual training, and recordkeeping.
A complete HCP under 29 CFR 1910.95 includes noise monitoring, audiometric testing, hearing protector provision, training, and recordkeeping.
Question 2: At what noise exposure level must employees be enrolled in a hearing conservation program?
- 85 dBA TWA (the action level) (Correct answer)
- 90 dBA TWA (the PEL)
- 80 dBA TWA
- 100 dBA TWA
Correct answer: 85 dBA TWA (the action level)
OSHA action level of 85 dBA TWA triggers hearing conservation program requirements.
The 85 dBA action level is set below the 90 dBA PEL to provide a safety margin. At 85 dBA, the full HCP is required. At 90 dBA, additional requirements apply.
Question 3: What is the role of the supervising professional in a hearing conservation program?
- An audiologist or physician who reviews audiograms, identifies problem cases, and provides clinical oversight (Correct answer)
- A safety manager who purchases hearing protectors
- An OSHA inspector who conducts annual audits
- A noise control engineer who designs modifications
Correct answer: An audiologist or physician who reviews audiograms, identifies problem cases, and provides clinical oversight
The supervising professional provides clinical oversight including reviewing audiometric results and determining STS significance.
OSHA requires that a licensed audiologist or physician oversee the audiometric testing component, review problem audiograms, and advise on baseline revisions.
Question 4: How does a hearing conservation program differ from a hearing loss prevention program?
- A hearing loss prevention program adds proactive elements beyond OSHA minimum requirements (Correct answer)
- They are identical terms
- A hearing loss prevention program only applies to military settings
- A hearing conservation program is more comprehensive
Correct answer: A hearing loss prevention program adds proactive elements beyond OSHA minimum requirements
A hearing loss prevention program goes beyond OSHA minimums by incorporating engineering controls, program evaluation, and management commitment.
Additional elements include active noise control, ototoxicity monitoring, fit testing, program evaluation, management accountability, and worker involvement.
Question 5: What triggers the mandatory use of hearing protectors in an OSHA HCP?
- Exposure at or above 90 dBA TWA, or any exposure above 85 dBA for employees who have experienced an STS (Correct answer)
- Any noise exposure above 80 dBA
- Only when the employer decides protectors are necessary
- After three consecutive unchanged audiograms
Correct answer: Exposure at or above 90 dBA TWA, or any exposure above 85 dBA for employees who have experienced an STS
OSHA mandates hearing protector use at or above 90 dBA PEL and for any STS employee exposed above 85 dBA.
Between 85-90 dBA, protectors must be available but use is voluntary unless an STS has occurred. At 90+ dBA, use becomes mandatory with attenuation requirements.
Question 6: What is the purpose of including noise monitoring as a component of the HCP?
- To identify which employees are exposed at or above the action level and must be included (Correct answer)
- To generate marketing data for the protector program
- To satisfy fire marshal requirements
- To determine warranty coverage on equipment
Correct answer: To identify which employees are exposed at or above the action level and must be included
Noise monitoring identifies employees exposed at 85 dBA TWA or above for HCP enrollment and helps characterize exposures for protector selection.
Monitoring serves to identify exposed employees, characterize exposures, select appropriate protectors, identify areas needing engineering controls, and establish exposure records.
