Once the ladder is clean, perform a visual inspection to log any possible defects. After the defects are repaired, you can protect the ladder by applying a mild liquid car wax to the side rails. Additionally, apply the wax to accessible lock parts. Under normal conditions, the inspection, washing, and waxing should be done twice yearly. In a hostile environment, complete these steps more frequently as required.
Testing is the word everyone loves to hate.
You have a plan in force to test your personal protection gear and your unit's brakes, as your life depends upon these items working properly when the need is greatest. The N.F.P.A. also requires you test ladders any time the ladders are damaged or exposed to high temperatures. Again, at the time of this printing, the N.F.P.A. requires, as a minimum, that a ladder be tested annually. Become familiar with the current testing requirements and complete the tests. Cut out portion of damaged rung between ladder side rail.
