ALI: American Ladder Institute
ALI, the American Ladder Institute, is made up of members from the US and Canada who are ladder manufacturers and manufacturers of ladder components. It was founded in 1947 and is a Chicago-based nonprofit association dedicated to promoting safe ladder use. ALI is the ANSI approved developer of safety standards for the ladder industry. Standards from ALI are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: [email protected] or 1-212-642-4980 or Request Proposal Price.

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 A14.2-2017
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 A14.5-2017
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 A14.11-2018
Safety Requirements for Stepstools
This standard prescribes rules governing the safe construction, design, testing, care and use of wood, metal, plastic and reinforced plastic stepstools of various configurations for duty ratings of 200, 225, 250, 300 and 375 lbs. It applies to stepstools that resemble conventional stepladders in their appearance as well as those that do not. It does not cover stepstools that do not meet the general requirements of this standard, nor does it cover accessories that may be installed on or used in conjunction with stepstools. This standard does not apply to those products currently covered by ANSI A14.7 (Mobile Ladder Stands and Mobile Ladder Stand Platforms).
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 A14.2-2007
American National Standards for Ladders - Portable Metal - Safety Requirements
This standard prescribes rules governing the safe construction, design, testing, care and use of portable metal ladders of various types and styles. Ladder Types included are:
| Duty Rating | Ladder Type | Working Load (pounds) |
| Special Duty | IAA | 375 |
| Extra Heavy-Duty | IA | 300 |
| Heavy-Duty | I | 250 |
| Medium-Duty | II | 225 |
| Light-Duty | III | 200 |
Note: Ladder type step stools are covered by A14.2. It is recognized that a step stool standard is under development. When the step stool standard is approved, A14.2 will no longer cover ladder type step stools.
These requirements are also intended to prescribe rules and criteria for labeling/marking of the kinds of portable ladders cited in this standard, but exclusive of furniture type step stools and special purpose ladders. These labeling/marking requirements do not apply to those situations where training, supervision, or documented safety procedures would be in conflict, or serve in lieu of, these labeling/marking requirements.
