ASME A17

Elevators and escalators have long been considered the safest form of public transport, delivering millions and millions of
rides without anomalies. A17 is a key reason why.

The ASME A17.1 / CSA B44 Safety Code for Elevators and Escalators has become the accepted guide throughout North America forthe design, construction, installation, operation, inspection, testing, maintenance, alteration, and repair of elevators, escalators and related conveyances. First published by ASME in 1921,A17.1 has been a primary source for all subsequent standards governing elevators and escalators worldwide.
