Jan. 27, 2012 – The American Ladder Institute, the national trade association representing the North American ladder industry, has released the updated A14.7 standard, which provides technical specifications for mobile ladder stands and mobile ladder stand platforms. The standard prescribes rules for mobile ladders, also referred to as rolling ladders, which are primarily used in the workplace and are generally purchased to perform a specific task.

“Use of mobile ladders and mobile ladder stands and platforms continues
to increase. This revision provides additional clarity and direction for
safe design and operation,” said Marty Silverman, A14.7 subcommittee
chair. “The American Ladder Institute is committed to ladder safety and
the continued advancement of this standard is an example of that.”

This revision replaces A14.7 2006 and includes new and/or enhanced
definitions, testing protocols and user requirements; revised drawings and an expanded label/marking section.
