Choose the Right Ladder
There are three basic portable ladder types:
Type I – Industrial: heavy-duty with a load capacity not more than 250 pounds.
Type II – Commercial: medium-duty with a load capacity not more than 225 pounds. (Suited for painting and similar tasks.)
Type III – Household: light-duty with a load capacity of 200 pounds.
There are many types of ladders available on the market. If it is intended to be portable and used by a single person, it should fit into one of the three basic categories.
The most common type of ladder in the home is a stepladder.
Ladders commonly come in three materials: aluminum, wood, or fiberglass.
Aluminum is the most durable, but will conduct electricity, making it dangerous for use around electricity. Wood may rot. Fiberglass is the best combination of durability and non-conductivity, but is also the most expensive.
Using a Ladder
Make sure the ladder is suited for the type of job you plan to do (see the types above).
Before using a ladder, especially a ladder that has been stored in the garage for a while, inspect it for cracks or broken joints.
Place your ladder on a stable, even, flat surface.
Never place a ladder on top of another object.
Use the 1:4 ratio to ensure a stable working platform. Place the base of the ladder 1 foot away of whatever it leans against for every 4 feet of height to the point where the ladder contacts at the top
When using an A-frame stepladder, make sure the brace is locked in place.
If climbing onto another surface, make sure the ladder extends at least three feet past the platform you're climbing onto.
Secure tall ladders by lashing or fastening the ladder to prevent movement.
Always face the ladder when climbing or descending.
Keep both feet on the ladder - never put one foot on a rung and the other foot on a different surface.
Do not climb higher than the second rung on stepladders or the third rung on straight or extension ladders.
Never stand on the top of the paint shelf of a stepladder.
Keep your belt buckle (if you have one) positioned between the rungs so it doesn't catch.
Never leave ladders unattended - kids love them.
When working with electricity, use a ladder made of wood or fiberglass.
