Which document must be followed when designing and installing elevator systems?

The ANSI A17.1 standard is a key document that outlines the safety requirements and guidelines for the design, construction, installation, operation, inspection, testing, maintenance, and repair of elevators and escalators. It is essential for ensuring that elevator systems are safe for public use and meet the necessary regulatory standards.

This standard addresses a range of factors critical to elevator systems, including performance requirements, safety measures, and operational protocols. By adhering to ANSI A17.1, designers and installers can ensure that their work not only complies with legal requirements but also promotes the safety and reliability of elevator systems.

While the other options relate to important safety and quality standards—such as ISO 9001 for quality management systems, NFPA 70 which covers electrical wiring, and OSHA 1910 focusing on occupational safety and health—the ANSI A17.1 standard is specifically tailored to elevator systems, making it the authoritative document in this context.
