Which federal regulations govern elevator maintenance?

The American Society of Mechanical Engineers (ASME) A17.1 code is correctly identified as governing elevator maintenance because it sets the safety standards for elevators and escalators in the United States. This code encompasses design, construction, installation, operation, inspection, maintenance, and modernization of elevators and related equipment, ensuring public safety and providing guidelines that must be adhered to by manufacturers and maintenance professionals in the industry.

The other options pertain to different aspects of safety and engineering standards but do not specifically address elevator maintenance as comprehensively as the ASME A17.1 code does. For instance, the National Electrical Code (NEC) focuses on electrical installations and safety practices, while OSHA standards primarily address workplace safety regulations across various sectors, not limited solely to elevators. The ANSI guidelines create standardization in various fields but do not enforce maintenance protocols specific to elevators. Thus, ASME A17.1 is the most pertinent regulation for elevator maintenance practices.
