Some ladder safety rules depend on the type of ladder you use.

Three rules for extension ladders include:

  1. Secure the ladder so it can't inadvertently slide out from under you. One way to do this is to tie a lower rung to an anchor point (e.g., vertical I-beam).
  2. Leave at least three rungs of overlap between sections, or get a longer ladder.
  3. Extend the ladder so it reaches 3 ft above the top supporting point.

Three rules for step ladders include:

  1. Open it completely, and lock the braces.
  2. Rest all four feet on level footing.
  3. Stand only on steps that are below the top step.
