5 real sample questions

Within what timeframe of an employee's first exposure at or above the action level must a valid baseline audiogram generally be established?

A. Within 6 months

B. Within 3 years

C. Within 1 month

D. There is no timeframe requirement

Show answer and reasoning

Correct answer: A. Within 6 months

B: 3 years significantly overstates the general timeframe.
C: 1 month understates the general timeframe.
D: A specific timeframe requirement does exist.

Source: 29 CFR 1910.95(g)(5)

At what 8-hour time-weighted average (TWA) noise exposure does OSHA’s hearing conservation program requirements (monitoring, audiometric testing, training) get triggered?

A. 80 dBA

B. 85 dBA

C. 90 dBA

D. 95 dBA

Show answer and reasoning

Correct answer: B. 85 dBA

A: 80 dBA is below the action level; no OSHA-mandated hearing conservation program obligations attach at this exposure alone.
C: 90 dBA is the permissible exposure limit (PEL), not the action level that triggers the hearing conservation program.
D: 95 dBA is well above the action level and is not the trigger point defined in the standard.

Source: 29 CFR 1910.95(c)(1)

What is the permissible exposure limit (PEL) for occupational noise as an 8-hour time-weighted average under 1910.95?

A. 85 dBA

B. 87 dBA

C. 90 dBA

D. 100 dBA

Show answer and reasoning

Correct answer: C. 90 dBA

A: 85 dBA is the action level that triggers the hearing conservation program, not the PEL itself.
B: 87 dBA is not a figure used in the general industry noise standard.
D: 100 dBA is a permissible level only for very short exposure durations under Table G-16, not the 8-hour PEL.

Source: 29 CFR 1910.95(b)(1)

Under Table G-16, what exchange (trading) rate does OSHA use when calculating permissible noise exposure duration as sound level increases?

A. 3 dB exchange rate

B. 4 dB exchange rate

C. 5 dB exchange rate

D. 10 dB exchange rate

Show answer and reasoning

Correct answer: C. 5 dB exchange rate

A: A 3 dB exchange rate is used by NIOSH’s recommended criteria and some international standards, not OSHA’s Table G-16.
B: A 4 dB exchange rate is not used in any OSHA noise table.
D: A 10 dB exchange rate is not the rate reflected in Table G-16; OSHA’s permissible duration halves for every 5 dB increase.

Source: 29 CFR 1910.95(b)(1)

Per Table G-16, what is the maximum permissible daily exposure duration at 95 dBA?

A. 8 hours

B. 4 hours

C. 2 hours

D. 1 hour

Show answer and reasoning

Correct answer: B. 4 hours

A: 8 hours is the permissible duration at 90 dBA, not 95 dBA.
C: 2 hours is the permissible duration at 100 dBA, one 5 dB step higher than 95 dBA.
D: 1 hour is the permissible duration at 105 dBA, not 95 dBA.
