Elevator and Escalator Code Compliance
What the code-compliance domain tests
Maryland elevator and escalator work is built on adopted standards, not local habit. New installations and alterations must satisfy the current ASME A17.1/CSA B44 Safety Code for Elevators and Escalators; existing elevators that are not altered are evaluated under ASME A17.3. Escalators and moving walks are covered in A17.1. The exam asks you to choose the correct code path, identify required permits and inspections, and recognize clearances, guarding, and fire-service features.
Core rules
- A permit is required before installing, altering, or replacing major equipment; work must be inspected by a qualified elevator inspector before a certificate of operation is issued.
- Hoistway, pit, machine-room, and car clearances are not suggestions: they protect against crush, shear, and fall hazards. Guarding around exposed sheaves, belts, and rotating equipment is required.
- Fire-service operation (Phase I recall and Phase II in-car operation) must be tested and maintained; it is a life-safety function, not an optional convenience.
- Escalator requirements include skirt guards, combplate protection, handrail speed, and stopping distance.
Worked example
A Maryland office building replaces a traction elevator's controller and door operator. The owner asks whether the old A17.3 rules can be used because the elevator is existing. Reasoning: the project is an alteration, not routine maintenance. The alteration must meet the current A17.1 requirements for the altered components and related interfaces. A17.3 may still govern unaltered existing features, but it cannot be used to avoid current requirements for the new work. A permit and acceptance inspection are required before return to service.
Traps
Do not apply A17.3 to a new installation. Do not treat a maintenance visit as an inspection that renews the operating certificate. Do not overlook Maryland amendments or the difference between a QEI inspector and a licensed mechanic.
