Your phone rings at 2 PM on a Tuesday. Someone's stuck in your elevator. They're scared. They're yelling. What you do in the next 60 seconds determines whether this ends as a minor incident or a major liability.
Here's what actually matters: call your elevator service company FIRST, not 911. Keep the passenger calm via the cab phone. Do NOT let anyone force those doors open. And document everything in real time.
The Correct Response Sequence
The moment you learn someone's trapped, your legal clock starts:
1. Communicate with the passenger immediately. Use the emergency phone in the cab. Tell them: you're aware, they're not in danger, help is coming, stay calm and seated.
2. Call your elevator service company's 24/7 emergency line. This is the FIRST call. Your service company dispatches an elevator industry professional who can perform authorized rescue. This is the legally correct chain.
3. Call 911 only if there's a medical emergency inside the cab. Fire department can provide medical assistance, but their role is passenger welfare, not mechanical rescue.
4. Do NOT let building staff or fire department force open doors. A forced-entry rescue that damages the door lock system can create the conditions for your next entrapment.
5. Document everything. Note when the elevator stopped, when you were notified, when you called, when the mechanic arrived. This documentation supports your state incident report.
Who's Actually Authorized to Perform a Rescue
Only two categories: IUEC-trained mechanics with active certification, and state-licensed elevator personnel. Your service company's on-call mechanic falls into the first category.
The fire department is NOT, by default, authorized to perform elevator rescue under ASME A17.1 (American Society of Mechanical Engineers elevator safety code). Forced entry through a hoistway door using pry tools can damage the door lock mechanism, the door operator, and the sill assembly. These are among the most common causes of future entrapments.
Many fire departments have trained elevator rescue teams that coordinate with service mechanics rather than forcing entry independently. If your local department doesn't have this training, make your service company call first.
What Actually Causes Entrapments
Understanding the causes helps you recognize when your callback pattern is a warning signal:
Hydraulic valve failure (most common). The down-direction control valve controls descent rate. When it sticks or fails, the elevator can't lower to a floor landing. The valve usually shows warning signs before full failure; sluggish descent, leveling variation. If you're seeing those callbacks and not getting a valve inspection, push for one.
Door lock fault. The door lock circuit must confirm every hoistway door is locked before the elevator can move. A failing lock relay or worn cam follower trips the safety circuit and stops the elevator mid-travel. Door lock faults are almost always preceded by intermittent door callbacks.
Power failure without battery lowering. Elevators are required to have an emergency lowering system (battery backup or ARD, Automatic Rescue Device) that brings the cab to the nearest floor on power loss. Many older buildings have ARD units with dead batteries that were never replaced.
Controller fault. Older relay logic controllers and aging solid-state drives can develop intermittent faults that stop the elevator unexpectedly. If your building has pre-1990 relay logic controls, controller-related stops are a significant entrapment risk.
The State Reporting Requirement
Most states require an incident report for any elevator entrapment, typically within 24 hours. This goes to your state inspection authority and becomes part of your elevator's permanent regulatory record.
Here's what most building owners don't realize: your service company's mechanic typically prepares this report, but the legal obligation to ensure it's filed rests with YOU, the building owner. Don't assume it happened. Verify it happened.
The entrapment log is part of your elevator's state record and is discoverable. Buyers, lenders, and insurers can access it. Multiple entrapments on the same elevator within 12 months is a red flag; it means the service company isn't identifying and resolving the root cause.
What Your Service Contract Must Include
Your service contract must include a 24/7 emergency response obligation for entrapments. Non-negotiable.
Maximum response time with a defined penalty. "Best efforts" language is unenforceable. Your contract should specify a maximum response time (30 minutes to 1 hour for entrapments is realistic) and what happens if they don't hit it. Guaranteed SLAs (Service Level Agreements) typically carry a premium, but for buildings with high entrapment risk, the additional cost is justified.
Emergency lowering system maintenance. The contract should explicitly include annual testing and battery replacement for the ARD.
Root cause documentation. After any entrapment, the service company should provide a written root cause analysis and corrective action plan. If this isn't required by contract, you're relying on verbal assurances.
How to Reduce Entrapment Risk
Entrapments follow patterns, and those patterns are visible in your callback record BEFORE the entrapment occurs.
Audit your callback pattern quarterly. Pull your callback log and look for recurring issues on the same elevator: door faults, leveling variation, nuisance trips. Three or more callbacks on the same symptom within 90 days without documented corrective repair is a warning sign. Understanding your real callback costs helps you budget for this risk and identify when patterns indicate deeper problems.
Confirm your ARD is tested annually. Ask your service company for written documentation of the last test date. If they can't produce it, schedule the test immediately.
Assess equipment age. Equipment over 30 years old, particularly hydraulic elevators with relay logic controls, carries materially higher entrapment risk. At 3+ entrapments in 12 months on equipment over 30, modernization (full rip-out and replace, typically $120K-$400K) is likely more cost-effective than continued reactive repair.
An entrapment is stressful. But it's also a moment of truth for your service company. How they respond tells you everything you need to know about whether they're protecting your building or just cashing your checks.
