Which hard hat class provides protection against high-voltage electrical hazards up to 20,000 volts?
Answer: Class B
Class B hard hats are designed for high-voltage electrical work and provide protection against electrical hazards up to 20,000 volts as well as impact.
An employee is working with chemicals that may splash. Which eye protection provides the BEST defense?
Answer: Chemical splash goggles with a sealed fit
Chemical splash goggles create a sealed barrier around the eyes from all directions, preventing liquid chemicals from entering from any angle.
What is the minimum NIOSH filter rating required for respiratory protection against airborne tuberculosis?
Answer: N95
N95 respirators, which filter at least 95% of airborne particles, are the minimum protection recommended by CDC and OSHA for tuberculosis exposure.
Which type of glove provides the BEST protection against electrical shock when performing work on energized circuits?
Answer: Rubber insulating gloves with voltage rating
Rubber insulating gloves are specifically designed and voltage-rated for electrical work, providing the dielectric protection needed against electrical shock.
Safety footwear with an ANSI/ASTM impact and compression rating primarily protects against which hazard?
Answer: Falling and rolling objects causing crush injuries
ANSI/ASTM-rated safety toe caps (steel or composite) protect the foot from falling objects and compressive forces from rolling or crushing hazards.
When is a full-body harness required rather than a body belt for personal fall arrest?
Answer: Body belts are prohibited for fall arrest; harnesses are always required
OSHA prohibits body belts for fall arrest because they can cause serious internal injuries during arrest; full-body harnesses must always be used for fall arrest applications.
A worker is exposed to 92 dBA noise for an 8-hour shift. Using the OSHA derating method [(NRR-7)/2], approximately what NRR is needed to reach safe exposure levels?
Answer: NRR 25
To reduce 92 dBA to OSHA's 90 dBA PEL requires ~2 dB attenuation; the OSHA method gives effective protection of (NRR-7)/2, so an NRR 25 provides approximately 9 dB — safely covering the needed reduction.
