|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,
ladder shoes, ladder levelers, ladder stabilizers or standoff
devices, ladder jacks, or ladder straps and hooks, that may be
installed on or used in conjunction with ladders.
Note: While ladder type stools are covered by
A14.1, it is recognized that a step stool standard is under
development. When the step stool standard is approved, A14.1 will
no longer cover ladder type step stools. The new standard will be
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.
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.
