failure to maintain proper work distances
▶ A ground-fault circuit interrupter (GFCI) protects workers from shock by:

walking/working level, and there must also be a means of protection from:
Answer: Falling objects between top rail and walking surface
▶ Employers must provide a training program that teaches employees who
might be exposed to fall hazards: Answer: How to recognize such hazards
and how to minimize them
▶ Safety nets must be strong enough to support workers who fall, and
must: Answer: Have small enough mesh openings that employee doesn't
fall through net itself
▶ Approximately 75 percent of struck-by fatalities involve: Answer: Heavy
equipment such as cranes or trucks
▶ It is preferable not to drive a vehicle in reverse if you have an obstructed
rear view, but if you do, make sure: Answer: Vehicle has an audible
reverse alarm
▶ Workers are most at risk from falling objects when standing or working:
Answer: -- under scaffolds
