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.
