6’ – Maximum allowable free-fall distance.
Fall protection equipment must be rigged so that it begins to stop a fall in 6’ or less.
6’ – Height where fall protection is required.
Workers exposed to a fall of greater than 6’ must use fall protection.
310 lbs. – Maximum weight of fall protection users, man & tools
OSHA limits the weight of fall protection users due to the 2:1 safety factor. Any employee weighing more than 310 lbs. must have anchorage points specifically designed and/ or certified to hold 10,000 lbs.
5000 lbs. – Minimum anchorage point rating
Anchor points used for attaching fall protection equipment must be certified by a Qualified Person.
42” – Maximum elongation of shock absorbing lanyards
Shock absorbing lanyards must bring an employee to a complete stop with in 42”.
2:1 – Safety factor must be maintained for Engineered Systems
All fall protection is based on this rule.
3 Systems – Self retracting lifeline, Shock absorbing lanyard, Rope and Grab
These are the only three components that you can attach to an anchorage and to your body harness for Fall Arrest applications.
2 Anchorage Points – Either Fixed or moving
Fixed anchorage points range from steel beams to engineered eye bolts. Moving anchorage points are generally horizontal lifelines and rigid rails.
3000 lbs. – Minimum anchorage rating when using most SRL’s
Since an SRL is designed to stop a fall immediately and limits the fall distance to 2’. The forces generated are much lower.
