Safety while working at height
Working at heights poses significant safety risks. 57% of fatal accidents while working at heights are due to falls from heights. Proper fall prevention methods include engineering controls, administrative controls, and personal protective equipment. Fall protection methods include safety harnesses, lifelines, nets, and fall arrestors. Training workers, maintaining good housekeeping, and following safety protocols are essential for preventing accidents while working at heights.
