To prevent falls from high working conditions, a technician should use which safety system?

• A. Personal fall arrest
• B. Safety harness
• C. Guard rails
• D. Hard hat

Answer: (A)

When you’re working at height, the goal is to prevent injury from falls by using a complete fall protection system. A personal fall arrest system provides the full setup needed to stop a fall safely if one occurs. It includes a full-body harness worn around the torso, a lanyard or self-retracting lifeline, and a secure anchor point positioned to safely absorb the fall’s energy. This combination is designed to halt a fall within a controlled distance and reduce the impact on the body.

Guard rails are helpful as a barrier, but they aren’t always present or feasible on all work surfaces and around equipment, so they can’t always prevent a fall. A safety harness alone isn’t enough without the connecting lanyard and anchor. A hard hat protects the head but does not prevent a fall.

So, the most reliable system for preventing falls from high working conditions is a personal fall arrest system.
