Standard Specification for Portable and Permanent Emergency Escape Ladders for Residential Use
ABSTRACT
This specification establishes the recognized performance requirements and corresponding test procedures for portable and permanent emergency escape ladders for residential use. The ladder shall show evidence of good workmanship and meet the requirements specified for the following: vertical static load; horizontal static load; rung/step strength; rung/step/side support shear; deployment weight; deployment time; hook or attachment stability; rung/step size; rung/step release mechanism; heat deflection temperature; standoff; designed length; rung/step spacing; rungs/steps; rated load; stress relief; and heat aging.
SCOPE
1.1 This specification establishes recognized performance requirements for portable and permanent emergency escape ladders for residential use.
1.2 This specification replaces provisional standard PS 117.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
