A tower crew member's safety glasses have a scratch across the lens directly in the line of vision. What is the correct action?
Answer: Replace them immediately before continuing work
Scratched lenses in the line of vision distort vision, reduce impact resistance, and can impair the wearer's ability to detect hazards; the glasses must be replaced immediately.
Which NWSA guideline addresses the maximum weight limit that a full-body harness must be rated for, including tools and equipment?
Answer: 310 lbs (141 kg) total, including worker, clothing, tools, and equipment
NWSA and ANSI Z359 standards require full-body harnesses used in tower work to be rated for a total system load of 310 lbs (141 kg), encompassing the worker, clothing, and all carried tools and equipment.
What is the shelf life of most latex and rubber PPE components such as rubber insulating gloves when stored properly?
Answer: Determined by the manufacturer with periodic retesting required
Rubber and latex PPE components such as insulating gloves have manufacturer-specified shelf lives and must be periodically retested for continued electrical protection, regardless of appearance.
When working at height in conditions below freezing, which adaptation to PPE is most important for maintaining safety?
Answer: Using thermal inner layers under the harness and ensuring harness fit is re-checked after layering
Wearing thermal layers under a harness can change its fit and adjustment; workers must re-check and re-adjust harness fit over cold-weather clothing to ensure it remains snug and effective.
Which ASTM standard governs the testing and use of rubber insulating gloves for electrical protection in tower work?
Answer: ASTM D120 and ASTM F496
ASTM D120 covers the specification for rubber insulating gloves, and ASTM F496 covers the in-service care and use of insulating gloves and sleeves, both of which apply to electrical PPE in tower work.
What is the maximum permissible free-fall distance allowed when using a personal fall arrest system (PFAS) per OSHA 29 CFR 1926.502?
Answer: 6 feet (1.8 m)
OSHA 29 CFR 1926.502(d)(16)(iii) limits free fall to no more than 6 feet (1.8 m) when using a personal fall arrest system to minimize forces on the body during arrest.
How should a hard hat suspension system be inspected for serviceability before each use?
Answer: Inspect suspension bands for fraying, tears, loss of elasticity, and check that all attachment points are secure
The suspension system absorbs impact energy; it must be checked for fraying, tears, loss of elasticity, and secure attachment to the shell before each use to ensure it will perform correctly in an impact.
