What is ASME A17.1/CSA B44 that I keep reading about?
ASME A17.1/CSA B44 is the Safety Code for Elevators and Escalators. In 1921 the American Society of Mechanical Engineers (ASME) developed uniform safety requirements for elevators, and published the first edition of ASME A17.1. The code is intended to serve as the basis for the design, construction, installation, operation, testing, inspection, maintenance, alteration, and repair of elevators and escalators.
