I believe that there are several people who need to read a few snippets from the OSHA safety manual.
* Self-supporting (foldout) and non-self-supporting (leaning) portable ladders must be able to support at least four times the maximum intended load, except extra-heavy-duty metal or plastic ladders, which must be able to sustain 3.3 times the maximum intended load.
* Non-self-supporting ladders, which must lean against a wall or other support, are to be positioned at such an angle that the horizontal distance from the top support to the foot of the ladder is about 1/4 the working length of the ladder.
* In the case of job-made wooden ladders, that angle should equal about 1/8 the working length. This minimizes the strain of the load on ladder joints that may not be as strong as on commercially manufactured ladders.
* Ladder rungs, cleats, or steps must be parallel, level, and uniformly spaced when the ladder is in position for use. Rungs must be spaced between 10 and 14 inches apart.
* For extension trestle ladders, the spacing must be 8-18 inches for the base, and 6-12 inches on the extension section.
* Rungs must be so shaped that an employee’s foot cannot slide off, and must be skid-resistant.
* Foldout or stepladders must have a metal spreader or locking device to hold the front and back sections in an open position when in use. (See Figure 4.)
* When two or more ladders are used to reach a work area, they must be offset with a landing or platform between the ladders.
* The area around the top and bottom of ladder must be kept clear.
* Ladders must not be tied or fastened together to provide longer sections, unless they are specifically designed for such use. (See Figure 5.)
* Never use a ladder for any purpose other than the one for which it was designed.
