Choosing the right size or length ladder is just as important as the style. One of the most common and potentially dangerous ladder selection mistakes is purchasing a ladder which is either too short or too long.
STEP 1 : SELECTING THE RIGHT TYPE
Which kind of ladder is right for the job - step stool, stepladder, extension ladder or multipurpose?The intended task and the work environment help determine the style of ladder best designed to keep you safe and productive on the job.
STEP 2 : SELECTING THE RIGHT HEIGHT
Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line. This will allow enough length for proper setup. Overlap of ladder sections, height restrictions of the highest standing level, and where appropriate, the extension of the ladder above the roof line. The highest standing level is four rungs down from the top. Never stand on the ladder above the support points or roof line.
The highest permitted standing level on a stepladder is two steps down from the top. A person standing higher may lose their balance and fall. A person's maximum safe reaching height is approximately 4' higher than height of the ladder. For example, a typical person can safely reach an 8' ceiling on a 4' ladder.
STEP 3 : SELECTING THE WORKING LOAD
STEP 4 : SELECTING MATERIAL
Fiberglass - Electrically non-conductive, great value, strong, preferred ladder material.
Aluminium - Strong, lightweight, corrosion resistant.
Timber - Electrically non-conductive when clean and dry.
