Final answer:
Fall restraint and personal fall arrest systems on a mobile elevated work platform are safety measures used to prevent workers from falling and reduce the risk of injuries. Fall restraint systems restrict worker movement, while personal fall arrest systems arrest a fall and protect the worker.
Step-by-step explanation:
Fall restraint and personal fall arrest systems are important safety measures used on a mobile elevated work platform (MEWP) to prevent workers from falling and reduce the risk of injuries or fatalities.
A fall restraint system consists of a full-body harness connected to a fixed anchorage point on the MEWP. It restricts the worker's movement and prevents them from reaching the edge of the platform. This system is designed to keep the worker securely positioned on the platform, minimizing the risk of falling.
A personal fall arrest system, on the other hand, is a more comprehensive safety system that includes a full-body harness, a lanyard or lifeline, and an anchorage point. The harness is worn by the worker and connected to the lifeline, which is then attached to the anchorage point. If a worker were to fall, the fall arrest system would activate and reduce the impact force by deploying a shock-absorbing lanyard or other safety devices. This system is designed to arrest the fall and protect the worker from serious injuries.
