Q

What are the OSHA 1926.453 Regulations?

A

Aerial lifts acquired before January 22, 1973 which do not meet the requirements of ANSI A92.2-1969, may not be used after January 1, 1976, unless they shall have been modified so as to conform with the applicable design and construction requirements of ANSI A92.2-1969. Aerial lifts include the following types of vehicle-mounted aerial devices used to elevate personnel to job-sites above ground: 1) Extensible boom platforms; 2) Aerial ladders; 3) Articulating boom platforms; 4) Vertical towers; and 5) A combination of any such devices.
