Methods of Fall Protection; Avoiding the negative effects of gravity.
- Exclusion restraints keep a minimum of 6.5 feet away from the fall hazard using some form of demarcation such as raised string line or flagging tape.
- Guardrail restraints keep a person behind a fence or other structure which prevents approaching a fall hazard. These guardrails must meet a minimum standard of load and construction.
- Fall restraint is a system that tethers a worker so that they can work up to the fall hazard, but be physically restrained from an actual fall.
- Fall arrest stops a worker’s fall once it has started. A fall arrest system must not only stop the fall, but must do so conforming to limitation on arrest forces and therefore fall distances.
Arrest & Restraint Achors: Anchor points are the heart of any fall protection system.
An anchor used for restraint must be capable of withstanding 800 lbs. of force.
An anchor used for arrest must be capable of withstanding 5000 lbs. of force.
- Engineered anchors are permanently affixed to the building and specifically designed to be used as anchors. These come in several different forms,
depending on their intended use.
- Improvised anchors are some other object that is capable of withstanding the 800/5000 lbs. of force and is put into use as an attachment point for a fall restraint or arrest system. Examples could include fence posts, large trees, and building columns.
