Which OSHA permissible exposure limit (PEL) standard applies to general industry for airborne contaminants?
Answer: 29 CFR 1910.1000
29 CFR 1910.1000 establishes PELs for air contaminants in general industry workplaces.
A hierarchy of controls lists elimination, substitution, engineering controls, administrative controls, and PPE. Which is considered MOST effective?
Answer: Elimination
Elimination physically removes the hazard at the source and is the most protective control measure.
The ACGIH TLV-TWA represents the average airborne concentration over which time period?
Answer: 8-hour workday
The TLV-TWA is a time-weighted average concentration for a conventional 8-hour workday.
Industrial hygiene practice follows which fundamental approach to protecting worker health?
Answer: Anticipation, Recognition, Evaluation, Control
The AREC model—Anticipation, Recognition, Evaluation, and Control—is the core framework of industrial hygiene practice.
When evaluating noise exposures, OSHA uses which exchange rate (doubling rate) in its hearing conservation standard?
Answer: 5 dB
OSHA's noise standard uses a 5 dB exchange rate, meaning allowable exposure time halves for every 5 dB increase.
What is the primary purpose of a Job Hazard Analysis (JHA)?
Answer: To identify and control hazards associated with specific job tasks
A JHA systematically breaks down job tasks to identify and control potential hazards before injuries occur.
Which type of ventilation dilutes contaminants by mixing contaminated air with clean air throughout a work space?
Answer: Dilution ventilation
Dilution ventilation reduces airborne contaminant concentrations by mixing large volumes of outdoor air with room air.
