Note: | Ladders subjected to certain acids or alkali materials may experience chemical corrosion and a reduction in strength. Consult the manufacturer or a qualified person prior to use. |
Table 1 Ladder Inspection Criteria
When the ladder is: | Do the following: |
First placed into service as necessary while in service | Inspect the ladder for visible defects, including, but not limited to: 1. Working parts; and 2. Rung or step connections to the side rails. |
Damaged by impact or tips over | 1. Visually inspect the ladder for dents, bends, cracks or splits 2. Check: a. Rung or step connections to the side rails. b. Hardware connections. c. Rivets for shear damage. d. All other components. |
Exposed to excessive heat such as a fire | 1. Visually inspect the ladder for damage. 2. Test for deflection and strength characteristics using the "in-service use tests" contained in the appropriate ANSI. EXEMPTION: Job-made wooden ladders are not to be subjected to load or impact tests. Those tests may weaken lumber components or fasteners, causing hidden damage that could result in sudden failure during use. |
EXEMPTION: | The minimum clear width does not apply to ladders with narrow rungs that are not designed to be stepped on, such as those located on the tapered end of orchard ladders and similar ladders. |
