CAOHC - Council for Accreditation in Occupational Hearing Conservation Worker Training and Education Questions and Answers

Question 1

According to OSHA's Occupational Noise Exposure standard (29 CFR 1910.95), which of the following topics is a mandatory component of the annual training program for all employees exposed at or above the action level?

Accepted Answer

The effects of noise on hearing.

Answer

OSHA 29 CFR 1910.95(k) explicitly requires that the annual training program covers several key topics, including the effects of noise on hearing; the purpose, advantages, and disadvantages of various hearing protectors; instructions on the selection, fitting, use, and care of protectors; and the purpose and procedures of audiometric testing. The other options are not mandatory components of this specific training.

Question 2

During a training session, an employee states, "I've worked in this noise for 20 years and my hearing is fine. I don't need earplugs." What is the MOST effective initial response for the OHC to encourage compliance and understanding?

Accepted Answer

"Noise-induced hearing loss is gradual and painless, so you may not notice the change from day to day."

Answer

This response is educational and non-confrontational. It addresses the employee's perception directly by explaining the insidious, gradual nature of noise-induced hearing loss. This helps them understand the risk without immediately escalating to threats (A) or simply being dismissive (D). While reviewing the audiogram (B) is a good step, explaining the nature of the damage first is a more effective initial educational approach.

Question 3

Which of the following is a key element of an effective hearing conservation training and education program?

Accepted Answer

Providing a wide variety of hearing protection devices and training employees on how to select one based on comfort and fit.

Answer

OSHA requires employers to provide a variety of suitable hearing protectors (29 CFR 1910.95(i)(3)). A critical part of effective training is teaching employees how to select a protector that is comfortable and effective for them. Personal choice, when guided by proper training, is crucial for user acceptance and consistent, correct use. The other options describe characteristics of ineffective programs.

Question 4

According to the OSHA standard, when must an employee who is included in a hearing conservation program receive their initial training?

Accepted Answer

Prior to or at the time of their first exposure at or above the action level.

Answer

To be effective, training must provide employees with the knowledge to protect themselves before they are exposed to the hazard. While the baseline audiogram has a 6-month window, training on hazards and protection must be provided before or concurrent with the initial hazardous noise exposure to be compliant and protective.

Question 5

An OHC is explaining an annual audiogram to an employee who has no significant threshold shift. Which statement is the most appropriate and clear way to communicate the results?

Accepted Answer

"This test shows that your hearing hasn't changed much since your first test here. That's great news and suggests your earplugs are working well for you."

Answer

This statement is clear, positive, uses layperson's terms ("hasn't changed much"), reinforces the purpose of the test, and links the good result to the employee's protective action (earplugs are working). Option B is filled with jargon. Option C is incorrect, as OHCs can and should provide basic explanations. Option D is overly simplistic and misses a key educational opportunity to reinforce positive behaviors.
