Ladder Safety

Ladder safety standards published by the American Ladder Institute provide manufacturers the requirements for the construction, design, testing, labeling and marking of ladders. Guidelines for safe use of ladders, and proper disposal of ladders help prevent accidental falls and ladder injuries. ALI ladder standards guide users on purchase requirements and instructions for personnel training, care, use, and in the preparation of motivational / instructional material. Familiarity with ladder safety practices can reduce workplace injuries. The standards address manuals, and posters used to heighten ladder safety awareness. Ladder standards provide the manufacturer, purchaser, and user of ladders with a set of performance and dimensional requirements against which a ladder may be compared. Standards for fixed and mobile ladders, portable ladders, scaffolding, attic ladders and machine ladders are available and more may be found using search. Packages of ANSI ladder safety standards are available, or each standard can be purchased separately as a PDF. Applications and materials of construction for ladders are covered in different standards. ASC A14 develops standards for design, construction, test, selection, care, and safe use of ladders and reviews them every five years.

ANSI ASC A14.2-2017

Ladders - Portable Metal - Safety Requirements

The purpose of this standard is to provide reasonable safety for life, limb, and property. In order to develop an effective safety program, the standard may serve also as a basis for purchase requirements and for instructions in personnel training, and in the preparation of motivational/ instructional material such as safety practices, manuals, posters, and the like. This standard is also intended to provide the manufacturer, purchaser, and user of metal ladders with a set of performance and dimensional requirements against which a product may be compared. It is not the purpose of this standard to specify all the details of construction of portable metal ladders. The limitations imposed are for the purpose of providing adequate general requirements and testing methods needed for consistency.


ANSI ASC A14.3-2008 (R2018)

Ladders - Fixed - Safety Requirements

This standard prescribes minimum requirements for the design, construction, and use of fixed ladders, and sets forth requirements for cages, wells, and ladder safety systems used with fixed ladders, in order to minimize personal injuries. All parts and appurtenances necessary for a safe and efficient ladder shall be considered integral parts of the design.


ANSI ASC A14.4-2018

Safety Requirements for Job-Made Wooden Ladders

This safety standard prescribes minimum requirements and recommendations for the construction, design, installation, and use of job-made wooden ladders in order to minimize personal injuries. This standard does not cover portable manufactured or portable job-made ladders, permanent fixed ladders, or mobile-equipment ladders.


ANSI ASC A14.5-2017

Ladders - Portable Reinforced Plastic - Safety Requirements

The purpose of this standard is to provide reasonable safety for life, limb, and property. In order to develop an effective safety program, the standard may serve also as a basis for purchase requirements and for instructions in personnel training, and in the preparation of motivational/instructional material such as safety practices, manuals, posters, and the like. This standard is also intended to provide the manufacturer, purchaser, and user of reinforced plastic ladders with a set of performance and dimensional requirements against which a product may be compared. It is not the purpose of this standard to specify all the details of construction of portable reinforced plastic ladders. The limitations imposed are for the purpose of providing adequate general requirements and testing methods needed for consistency.


ANSI ASC A14.7-2011

Safety Requirements for Mobile Ladder Stands and Mobile Ladder Stand Platforms

This standard prescribes rules and requirements governing the proper design, construction, testing, care, use, and maintenance of mobile ladder stands and mobile ladder stand platforms including labeling /marking of these units.


ANSI-ASC A14.9-2019

Safety Requirements for Disappearing Attic Stairways

This standard prescribes rules concerning the safe design, construction, testing, care, installation and use of permanently installed metal or wood, disappearing attic stairways of various types designed to be used for access to upper levels such as attics. Household units with duty ratings of 250, 300 and 350 lbs., or commercial units with a rating of 500 lbs. are the only units covered in this standard. This standard is not intended to apply to any attic stairway covered in any other ANSI A14 standards, or disappearing attic stairways intended for use with ceiling heights in excess of 12 feet. This standard also prescribes rules and minimum requirements for installation instructions and labeling of disappearing attic stairways in order to promote safety under normal conditions of usage.
