With spring comes warmer weather. At most facilities, that means doing "post-winter" preventive maintenance (PM) work. Much of this PM work likely will involve the use of ladders. For example, inspecting or relamping outdoor security lights, testing entryway sensors, checking roof-mounted HVAC units, and manually adjusting various types of overhead equipment are all typical "post-winter" activities.

Ladders may be permanently attached (common for roof access) or portable. If portable, they will be extension ladders or stepladders. Each type has its inherent dangers, but some general rules apply to all. For example:

  • Don't carry items up a ladder; use both hands to climb the ladder.
  • Use a rope and bucket or similar means to raise and lower tools.
  • Only one person on a ladder at a time.
