Technical Advice · Equipment Damage
What should an owner do after elevator water or fire damage?
Water, fire, smoke, heat, and sprinkler discharge can affect elevator equipment well beyond what is immediately visible. Electrical insulation, electronic controls, wiring, bearings, hydraulic components, door equipment, signal fixtures, and safety-related devices may experience corrosion, contamination, or latent deterioration.
Do not evaluate damage by appearance alone
Equipment can appear dry or operational after an event while moisture, smoke residue, corrosion, or contamination remains inside components, enclosures, conduit, connectors, or hydraulic systems. Damage assessment should consider both immediate failure and the possibility of future deterioration.
Identify what was exposed
The review may include controllers, drives, motors, machines, hydraulic power units, cylinders, traveling cables, door operators and locks, fixtures, wiring, junction boxes, pit equipment, safety devices, and cab materials. The type, duration, and location of exposure influence the evaluation.
Document condition before deciding repair scope
Photographs, service records, inspection findings, testing, and a component-by-component assessment can help distinguish unaffected equipment from equipment requiring cleaning, testing, repair, or replacement. This documentation can also support discussions among ownership, contractors, insurers, and other project parties.
Safety and reliability come first
Equipment should not be returned to normal service solely because it can be made to run. The appropriate qualified parties and authority having jurisdiction should determine applicable inspection, testing, and return-to-service requirements for the specific event and jurisdiction.
