This standard prescribes rules and establishes minimum
requirements for the construction, testing, care, and use of the
common types of portable wood ladders described herein in order to
ensure safety under normal conditions of usage.
It does not cover step stools (furniture type), except
laddertype step stools (see 6.4.4 for other exceptions). It also
does not cover ladder accessories, including, but not limited to,

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. It may
also assist 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 wood ladders with a set of specifications
and requirements against which a ladder may be compared.
It is not the purpose of this standard to specify all the
details of construction of portable wood ladders. The limitations
imposed are for the purpose of providing adequate general
requirements and testing methods needed for consistency.
