Extension Ladders: Extension ladders generally have two sections that operate in brackets to allow for adjusting the ladder’s length. OSHA notes that these types of ladders need a stable structure to hold loads, as they are not self-supporting.
OSHA recommends a variety of tips for safely using extension ladders, including:
- Ensure the extension ladder can support at least 4 times its maximum intended load.
(OSHA notes that extra-heavy-duty type 1A metal or plastic ladders should sustain at least 3.3 times their maximum intended load.) - Read and follow the manufacturer’s instructions.
- Have a competent person inspect all extension ladders before use. If a ladder is determined to be damaged, immediately mark it with a “defective” sign.
Never attempt to use a damaged ladder. - Place the ladder at the correct angle. When leaned against a wall, the ladder’s bottom should be one-quarter of its working length away from the wall.
- Keep the spaces around the top and bottom of the ladder uncluttered.
- Use a ladder with non-conductive side rails, if the ladder could come into contact with energized electrical equipment. Keep all ladders a minimum of 10 feet away from power lines.
- Never use an extension ladder horizontally.
- Maintain three points of contact (two hands and a foot, or two feet and a hand) when on a ladder.
- Do not carry tools when climbing or descending a ladder - use a tool belt instead.
- Ensure the ladder is not placed on a slippery surface.
Also good to note - when multiple trades are within the same area, it is a best practice to demarcate access point to the ladder, preventing accidental displacement.
