Unformatted text preview: Fall Protection Fall The Occupational Health and Safety Regulation requires workers to use a The Occupational Health and Safety Regulation requires workers to use a fall protection system where they could fall at least 3m (10 ft.) or where a fall from a lesser height may result in serious injury. Fall protection is the backup system planned for a worker who could loose his or her balance at height, in order to control or eliminate injury potential. How long does it take to fall? Many workers believe that they have time to regain their balance before they fall – this is not always true. The following table indicates how far you can fall in just a few seconds: Fall restraint or fall arrest? Fall Fall restraint systems prevent you from falling. Examples include: work­positioning systems using either safety belts or full body harness that attach you to an anchor and leave both your hands free to work Travel­restriction systems of guardrails or personal fall protection equipment used to prevent you from travelling to an edge from where you may fall Fall arrest systems protect you after you fall by stopping the fall before you hit the surface below. Examples include: Full body harness connected by lanyards or lifelines to secure anchors Safety nets Written fall protection plan Written A written fall protection plan is required prior to using a personal fall protection system for work with a potential fall hazard of 7.5 m (25 ft.) or more. The written plan should identify: Potential fall hazards on the job Types of fall protection systems to be used Instructions to workers on how to safely use the equipment Instructions on how to rescue a worker who has fallen and can’t initiate self­rescue Fall protection equipments Fall Safety belts You must never wear a safety belt in a fall arrest situation. If you fall into a safety belt, you could still suffer severe back and abdominal injuries. Restrict the use of safety belts to fall restraints only. Full body harness Full body harness A full body harness consists of straps passed over the shoulders, across the chest, and around the legs. In a fall, a full body harness protects you more than a safety belt, because it distributes the force of impact over a greater area of your body Lanyard Lanyard is a flexible line of webbing or a synthetic or wire rope used to secure a safety belt or full body harness to a lifeline or anchor. Anchors Anchors An anchor – what you connect your lanyard or lifeline to – is a key element of any personal fall protection system. An anchor may consist of a load­rated strap or sling wrapped around a substantial structural member on a building. An anchor may also be a manufactured component that permanently or temporarily attaches to a structure. Lifelines Lifelines Is a length of synthetic fibre or steel wire rope attached to an independent point of anchorage. A lifeline is typically used in conjunction with a fall arrest device, such as a rope grab. After a fall After a fall Immediately remove from service all equipment used to arrest the fall. You cannot use the equipment again until it’s been inspected and approved by the manufacturer or other approved agent, or by a professional engineer. ...
