Ladder Safety



The mission of the American Ladder Institute is to promote the safe use of our products 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

The American Ladder Institute (ALI) is a not-for-profit association dedicated to promoting safe ladder use. The ALI is comprised of members from the US and Canada who are ladder manufacturers and manufacturers of 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 was founded in 1947 and has evolved to fit the needs of the membership as the industry has changed. Construction materials and processes have developed according to changes in usage, duty ratings and industry need.
