Elevator and Escalator Code Requirements (ASME A17.1/CSA B44)
Domain 1 covers ASME A17.1/CSA B44 and the documents around it. The exam tests whether you can identify which standard and which edition governs an installation, and apply a specific rule rather than a general impression.
The document map
- A17.1/CSA B44 - the harmonized safety code for elevators, escalators, dumbwaiters and moving walks: design, construction, installation, operation, testing, maintenance, alteration and repair.
- A17.2 - the inspectors' manual that tells you how to perform routine, periodic and acceptance inspections and tests. It is procedure, not design law.
- A17.3 - safety requirements for existing installations, applied where the jurisdiction adopts it.
- A17.5 - component standards for controllers, door operators and similar equipment; A17.6 covers suspension means such as wire rope.
Rules that reappear on exams
Hoistway doors must be closed and locked before the car can move, and the car cannot run with a door unlocked outside the permitted leveling zone. Rated load appears on the capacity plate and drives brake, safety and rope sizing. Firefighter's service is a two-phase system: Phase I recall from the lobby, Phase II in-car operation. States such as Michigan adopt A17.1 by reference, so the adopted edition governs - not automatically the newest one published.
Worked example
A 1985 relay-controlled elevator has its controller replaced with a solid-state unit and power door operators installed. Correct analysis: this is an alteration, so the altered equipment must meet the A17.1 edition adopted by the jurisdiction, and the new controller must be a listed A17.5 component. Untouched equipment may remain under A17.3. It is not maintenance, and the 1985 code does not cover the new work.
Traps
Quoting the newest edition when the state adopted an older one; treating A17.3 as optional everywhere; calling an alteration a repair; confusing A17.1 requirements with A17.2 inspection procedures.
