10. PERSONAL PROTECTIVE EQUIPMENT When considering the amount of free space that is needed, the evaluation should be done separately for each case: 1. Choosing and location of the anchorage point 3.The length of the connecting device (e.g. rope or retractable webbing) 3. The worker’s height (2 m) 4. The length of the deceleration device (1,75 m) 5. Safety distance 1 m Keep in mind also possible pendulum effect! Fall arrest system The Work at Height regulations require employers to ensure measures to prevent falls from heights, whenever an employee works at height of over 2 meters where there is a risk of falling. Fall protection must be provided as preventive measure. Precautions include e.g. changing of working methods, ensuring handrails, safety nets. If it is not possible to provide preventive measures, use of personal protective equipments (full body harnesses, lifelines etc.) must be taken. Work at height includes e.g. working on scaffol without guard rails, roofs, lifting platforms and masts. Safety harnesses must be used when working in telescopic boom lift and aerial lift man baskets. Support safety belts and lanyards prevent the worker from getting into the area with fall risk, but they cannot to be used as fall protection. If a support safety belt or lanyard is used to support working position in the area where is fall risk e.g. mast works, also, fall protection must be used to ensure safety. Full body harnesses and other approved fall protection equipment (e.g. deceleration devices, retractable type fall arresters) is used if there is a risk of falling. There should be an adequate amount of free space under the working level. For example, when using a 2 meter long connecting device with deceleration mechanism, anchorage point is located on floor (foot) level (coefficient of fall 2): Connecting device 2 m + The worker’s height 2 m + Deceleration device opening 1,75 m + Safety distance 1 m 48 = 6,75 m Free space for falling
