Snow load will affect a deck’s weight load in a big way. However, 5,000 pounds is where many people stop reading. How many can you identify? "Anchorages used for attachment of personal fall arrest equipment shall be . In all cases, a safety factor of at least two should be applied when determining the minimum load that an anchorage point must support. Note that there is a small selection of shock absorbing devices that can allow a worker under 130 lbs. worker capacity, we know this is not related to the forces achieved during the arrest of a fall (which will always be greater than just the worker’s weight), and instead is only referencing the weight of the worker. So here we’ve seen 3 categories of numbers: worker capacity, anchor strength, and fall arrest forces, all of which operate independently from one another, and all of which are important to understand to work as safely as possible. They must visually inspect the location and decide whether or not that area is capable of supporting 5,000 pounds or other supporting weight depending on the category of anchorage. Increased weight leads to increased risk in the event of a fall. (1) Body belts or harnesses may be used for personal fall restraint. The minimum required anchor breaking strength for certified/engineered anchors.

Use a butane or propane burner with a 3-inch (76-mm) flame; 3. 2. Minimum required anchorage connector breaking strength for non-certified anchors (per ANSI) based on fall protection application (Restraint, Work Positioning, and Fall Arrest, respectively). In all cases, a safety factor of at least two should be applied when determining the minimum load that an anchorage point must support. (1) In a temporary fall restraint system, an anchor for a personal fall protection system must have an ultimate load capacity in any direction in which a load may be applied of at least (a) 3.5 kN (800 lbs), or (b) four times the weight of the worker to be connected to the system.

Planks greater than 10’ long require a 6” minimum and a 18” maximum overlap. When looking at a non-certified rescue anchor (i.e., running an anchor strap around a piece of structural steel) ANSI would require it to be able to support 3,000 lbs. If the system passes, then, a safety factor of two applied to 2,520 pounds would be approximately 5,000 pounds. For a square footing, M xx = q x B/8 (L – a) 2. How much weight must a scaffold be capable of supporting? (d) Personal fall restraint. Certification of each anchorage must be performed by a qualified person.
