Guide for facility & property managers

What to Do Before the Technician Arrives

When a door or dock fails, the minutes before a contractor shows up are yours to manage. The right moves make the site safe and the repair faster; the wrong ones turn a part into an injury. This is the calm version of that checklist.

First: is anyone in danger?

Before anything else — if a door or dock has trapped or injured someone, if there's a live electrical hazard, or if it's a fire situation, this guide is not the priority. Call 911, then account for people. The equipment can wait; a routing form certainly can.

Step 1 — Stop operating it

The single most common way a broken door or dock gets worse is someone cycling it "one more time" to see if it catches. A door that's off track, missing a spring, or binding after an impact can jump, drop, or snap a cable when you run it. If it's not behaving normally, stop pressing the button.

Step 2 — Know the stop-use signs

These conditions mean take it out of service immediately, not "use it gently":

  • A broken, separated, or visibly loose spring above an overhead door.
  • A frayed, slack, or hanging lift cable.
  • A door hanging crooked, racked, or with a buckled panel — it's off track.
  • A dock leveler that drifts, won't hold position, or has its lip partway out.
  • A gate that reverses erratically or has lost its safety sensors.
  • Anything that would put a person under a raised door or deck to inspect.

Step 3 — Red-tag and cordon

Borrow the discipline of lockout/tagout even for a simple "out of service" case: make it obvious to the next shift that the equipment must not be operated.

  • Put a clear sign at the control: "OUT OF SERVICE — DO NOT OPERATE."
  • Cone or tape off the opening on both sides so no one walks or drives through.
  • For a dock position, block the interior approach and the dock door so a forklift can't roll onto a leveler that won't hold.
  • Where equipment has a power disconnect and your site has a lockout/tagout program, follow it. OSHA's energy-control standard is the reference for isolating stored and electrical energy.

The line you don't cross

Don't attempt spring, cable, dock-leveler mechanism, or gate-operator repairs yourself, and don't let a willing employee "take a look" at them. These components hold the weight of the door or a loaded forklift under stored energy. DASMA is explicit that spring work is for trained door systems technicians only, and the same logic applies to leveler spring packs and hydraulics. This is where waiting for the pro is the whole point.

Step 4 — Secure the building if it's exposed

If the failure left an opening you can't close, protect it without putting anyone under the door: park a vehicle or loaded pallets across the opening, keep a trailer at the dock, and put eyes on it if it's a theft risk. The won't-close guide walks through this for overhead doors specifically.

Step 5 — Gather what the technician needs

You can shorten the repair — sometimes avoid a wasted first trip — by having this ready when you submit:

  • Photos. The whole unit, the specific failure, and the data plate if there is one. Photos are how this trade quotes; they beat a model number you probably don't have.
  • What it is and where. Door type or leveler type, rough size, and the dock or door number in a multi-bay building.
  • What happened and what it does now. An impact, a bang, a storm, or gradual — and whether it's stuck open, closed, or mid-travel.
  • Access and urgency. Your hours, how to reach you, and whether the building or a shipping lane is exposed right now.

The request form asks for exactly these, so the contractor who contacts you is already oriented.
