ALI A14.11 PDF

Scope

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 conventinal 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).

These requirements are also intended to prescribe rules and criteria for labeling/marking of the kinds of stepstools cited in this standard. 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.

Purpose

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 of wood, metal, plastic and/or reinforced plastic stepstools with performance and dimensional requirements against which this product may be compared. It is not the purpose of this standard to specify all the details of construction of wood, metal, plastic and/or reinforced plastic stepstools. The limitations imposed are for the purpose of providing adequate general requirements and testing methods.
