ANSI A14.2: 2000 - American National Standard For Ladders - Portable Metal - Safety Requirements
便携式金属梯的安全要求
Description: These standards detail specifications on the materials, construction requirements, test requirements, usage guidelines and labeling/marking requirements for portable ladders. The type of material to be used is determined by the environment the finished ladder will encounter (electrical hazards, temperature extremes, corrosion, outdoor weathering, etc.). Metal ladders do not have material guidelines. ladders are generally evaluated on their resistance to bending, strength in various positions and the quality of the individual components that make up the ladder.
Construction requirements include weight and size categories for portable ladders. Usage guidelines for portable ladders encompass selecting the proper ladder for the job being performed; inspecting prior to use to verify proper operation and cleanliness; evaluating ladder placement so that footing and top supports are secure and not creating a traffic hazard for pedestrians; utilizing proper climbing technique; and caring for and storing ladders. Ladders must be marked with ladder size, type, maximum length, number of sections (if appropriate), highest standing level, total length of sections (if applicable), model number, manufacturer's name, manufacturer's location, and date of manufacture. Usage guidelines and other warning statements must also be placed on the ladders in specific locations.
