A ladder-type step stool is a self-supporting, foldable, portable ladder that is non-adjustable in length, 32-inches or less in overall size, with flat steps and without a pail shelf. It is designed so that the ladder top cap as well as all steps can be climbed on. The side rails may continue above the top cap. It is intended for use by one person.
The length of a ladder-type step stool is measured along the front side rail from the feet at the bottom to the top cap. Any side rail extensions on the stool are not considered part of the step stool size.
Proper Use:
A ladder-type step stool requires level ground support for all four of its side rails. If this work site condition does not exist, a ladder-type step stool should not be selected for the job.
A ladder-type step stool must not be used unless its base is spread fully open and the spreaders locked. Ladder-type step stools are not to be used as single ladders or in the partially open position.
In order to prevent tipping, the step stool over sideways due to over-reaching, the user must climb or work with the body near the middle of the steps or top cap. The step stool should be set-up close to the work. Never attempt to move the step stool without first descending, relocating the step stool, and then re-climbing. Do not attempt to mount the step stool from the side or step from one ladder or step stool to another unless the step stool is secured against sideways motion.
When ascending or descending the step stool, always face the step stool.
The braces on the rear of a step stool are not intended for climbing or standing and must not be used for that purpose.
The anti-slip feet at the bottom of the step stool side rails must be present and in good condition prior to using. The step stool must not be used on ice, snow, or slippery surfaces unless suitable means to prevent slipping is employed.
A step stool must never be placed upon other objects such as boxes, barrels, scaffolds, or other unstable bases in an effort to obtain additional height.
To protect children, do not leave a step stool set up and unattended.
Proper Care:
A thorough inspection must be made when the step stool is initially purchased and each time it is placed into service. Clean the climbing and gripping surfaces if they have been subjected to oil, grease, or slippery materials. Working parts, bolts, rivets, step-to-side rail connections, and the condition of the anti-slip feet (safety shoes) shall be checked. If structural damage, missing parts, or any other hazardous defect is found, the step stool must not be placed into service and either discarded or competently repaired.
Step stools exposed to excessive heat, as in the case of fire, may have reduced strength. Similarly, step stools exposed to corrosive substances such as acids or alkali materials may experience chemical corrosion and a resulting reduction in strength. Remove these step stools from service.
Step stools with bent or broken side rails must be destroyed.
In the event a step stool is discarded, it must be destroyed in such a manner as to render it useless. Another person must not be afforded the opportunity to use a step stool that has been deemed unsafe.
Do not store other materials on the step stool while it is in storage.
