Why it matters

Scissor lifts are how we hang duct, run pipe, and set units overhead. Workers get hurt when the lift tips over on bad ground, when they climb the rails to reach, or when they get pinned against the ceiling. These are some of the most common lift accidents on commercial jobs.

The talk

Only trained workers run the scissor lift. Training covers the hazards of the lift you are using, how to use it, and its load limit. Before each shift, check the lift: guardrails and gate in place, the gate or chain closes, controls and emergency stop work, tires are good, no leaks, and the pothole guards drop when you raise the platform. Read the capacity plate. Count yourself, your partner, the duct, the pipe, and your tools. A lift loaded past its rating can tip or fail. If anything is broken, tag it out and tell the foreman. Do not use a lift with a missing rail or a gate tied open.

The guardrails are your fall protection on a scissor lift. Stay on the platform floor and keep the gate closed. Never stand on the midrail or top rail, and never put a ladder, bucket, or box on the platform to reach higher. If you cannot reach, lower the lift and move it closer, or get a taller lift. If your company or the lift maker requires a harness and lanyard, clip only to the anchor point the maker provides. Before you drive with the platform up, the floor must be close to level, solid, and clear of holes, drops, and debris. Look for floor openings, ramps, loading dock edges, and wet or soft ground.

Look up before you raise. Pipe, beams, joists, sprinkler lines, and light fixtures can pin you against the guardrail. Many crush injuries happen when someone leans over the control box while the lift is still moving up. Keep your body inside the rails and move slowly as you get close to anything overhead. Tell everyone on the platform before you move the lift. Keep people on the ground out from under the platform so falling tools or fittings do not hit them. Outdoors, check the wind rating on the plate, and bring the lift down if the wind picks up. Stay well away from overhead power lines.

Key points

Only trained workers operate the scissor lift.
Inspect the lift and read the capacity plate before each shift.
Keep the gate closed and stay on the platform floor.
Never climb the rails or use a ladder or bucket on the platform.
Drive with the platform up only on level, solid, clear floor.
Look up before raising and go slow near overhead objects.
Tell everyone on the platform before the lift moves.

Do this

Count all people, material, and tools against the load limit.
Lower and reposition the lift if you cannot reach.
Check for floor openings, ramps, and dock edges before driving.
Keep your body inside the rails while moving.
Tag out a lift with any broken part.

Do not do this

Do not tie the gate open or work with a missing rail.
Do not stand on the midrail or top rail.
Do not lean over the controls while the lift is rising.
Do not let anyone stand under the platform.
Do not use the lift outside in winds above its rating.

Talk about it

What is overhead in our work area that could pin someone on the platform?
Where are the floor openings, ramps, or soft spots on this level?
What are we loading onto the lift today, and is it under the rated capacity?
