Safety Awareness & Compliance Flashcards

In a manufacturing setting, which noise exposure level triggers OSHA's requirement to implement a hearing conservation program?

Answer: 85 dB(A) as an 8-hour time-weighted average

OSHA 29 CFR 1910.95 requires a hearing conservation program when noise exposure reaches or exceeds 85 dB(A) as an 8-hour TWA (the action level).

A chemical spill occurs in the production area. The primary reason to evacuate personnel not trained for spill response is to:

Answer: Prevent additional exposure and allow trained responders to control the hazard safely

Untrained personnel near a chemical spill increase the risk of additional exposures and injuries; evacuation limits harm while trained responders address the hazard.

Which ergonomic risk factor is most directly associated with repetitive strain injuries in production assembly work?

Answer: Performing the same motion repeatedly with little variation throughout a shift

Repetition is a primary ergonomic risk factor for musculoskeletal disorders (MSDs); performing the same motion repeatedly fatigues tissues and leads to injury over time.

According to OSHA, what is the minimum distance that electrical equipment operating at 50–300 volts requires as a limited approach boundary for unqualified persons?

Answer: Restricted to a distance set by the qualified worker; unqualified persons must not cross without escort

NFPA 70E and OSHA electrical safety standards require unqualified persons to remain outside the limited approach boundary, which is determined by the qualified worker based on voltage and conditions.

What is the purpose of a Job Hazard Analysis (JHA) in a production facility?

Answer: To identify hazards associated with each step of a job task and determine appropriate controls

A JHA breaks a job into steps, identifies hazards at each step, and establishes controls to eliminate or reduce those hazards before work begins.

An employer discovers that a worker was injured but only received first aid. Under OSHA recordkeeping rules (29 CFR 1904), this case is:

Answer: Not recordable if treatment involved only first-aid care as defined by OSHA

OSHA defines first-aid cases (using a specific list of treatments) as non-recordable; only injuries or illnesses requiring medical treatment beyond first aid must be entered on the 300 Log.

Which document outlines the specific steps an authorized employee must follow to safely shut down and de-energize a specific piece of equipment under a LOTO program?

Answer: Equipment-specific lockout/tagout procedure

OSHA 29 CFR 1910.147 requires written, machine-specific LOTO procedures that document every energy source, isolation point, and step needed to safely de-energize that equipment.
