About the American Ladder Institute

The mission of the American Ladder Institute (ALI) is to promote the safe use of ladders as well as advance the common business interests of our members through a commitment to:

  • Development and dissemination of appropriate standards.
  • Education of the public as to the proper selection, care and safe use of ladders
  • Representation of the interests of its members

ALI is a not-for-profit association dedicated to promoting safe ladder use. ALI is composed of members from the United States and Canada who manufacture ladders and/or ladder components. ALI is the American National Standards Institute (ANSI)-approved developer of ladder safety standards. Standards are technical specifications, developed and tested by subject experts, which prescribe rules governing the safety construction, design, testing, care, and use of various types of ladders.

ALI also offers a free, on-demand ladder safety training program. This training is a tool for the proper selection, care, and safe use of all ladders, including stepladders, single and extension ladders, articulated ladders, and mobile ladders.

ALI was founded in 1947 and has evolved to fit the needs of its membership as the industry has changed. Construction materials and processes have developed according to changes in usage, duty ratings, and industry need.
