IMG_0792Did you know there are height restrictions for portable ladders? Depending on the type of ladder and the ladder’s weight restrictions, there is a set height for the ladder to be used safely. OSHA has provided a list of safe ladder heights, organizing the list by types of ladders.

Here are the height restrictions:

Portable Wood Ladders:

  • Stepladders – Maximum 20’
    • Type I – Industrial – 3-20’
    • Type II – Commercial – 3-12’
    • Type III – Household – 3-6’
  • Portable Rung Ladders
    • Single Ladders – 30’
    • Two Section Ladders – 60’
    • Trestle / Extension Trestle – 20’
  • Special Purpose Ladders
    • Painter’s Stepladder – 12’
    • Mason’s Ladder – 40’
    • Trolly / Side-Rolling Ladders – 20’

Portable Metal Ladders:

  • Single Ladders or Individual Sections of Ladders – 30’
  • Two Section Ladders – 48’
  • Greater Than Two Section Ladders – 60’
  • Stepladders / Trestle Ladders (or Trestle Sections) / Platform Ladders – 20’

If your ladder is any taller than provided in these guidelines, you could be putting yourself at risk. Most ladders bought from a reputable company probably fit the parameters, but, having said that, it is still a good idea to familiarize yourself with the height guidelines and double check your ladder fleet.
