Aerial and Scissor Lift Toolbox Talk
A lift feels like a floor and behaves like a lever. Three things tip one over: soft ground, a boom out past the wheels, and somebody leaning on the rail.

The talk, read this out
Whoever is running the lift today, you are up first. Walk us through your pre start check, out loud, before you get in it.
There are two machines here and two different rules, which is where people get caught. In a boom lift, a bucket truck or anything that articulates, you wear a full body harness with a lanyard attached to the boom or the basket. In a scissor lift, the guardrails are the fall protection, so you stay inside them and you keep the chains or gates closed.
Never tie off to the structure you are working on from inside a boom lift. If the boom moves and you are anchored to a beam, the basket goes and you do not. That rule exists because it has happened.
The ground decides whether the machine stays up. Fresh backfill, a covered trench, a soft shoulder, a hidden septic lid. A lift that is fine on slab is a tip over on fill, and the load chart assumes firm and level, not close enough.
Look up before you go up. Ten feet is the minimum clearance from an overhead power line up to fifty kV, and more above that. A boom does not have to touch a line to kill somebody. Treat every line as live and assume nobody has de energized anything for you.
Do not climb on the rails. Ever. Not to reach the last foot, not to see over, not because you are almost done. The whole system, guardrails and harness both, assumes your feet are on the floor of the basket.
And the pre start. Controls at ground level and at the platform, emergency lowering, horn, tires, leaks, and the fact that the operator is trained on this specific model. The manual lives with the machine for a reason.
Point at these before anybody starts
A talk delivered in a trailer is a meeting. Stand where the work is and put a hand on each of these.
- The ground under all four wheels or outriggers, and what is underneath it
- Overhead: power lines, service drops, tree limbs, and the clearance to each
- The harness and lanyard for the boom lift, and where the anchor in the basket is
- The guardrails, gate and chains on the scissor lift
- The pre start checklist for this machine, filled in today, not last week
- The load rating plate, and what the platform is actually carrying today
The rules that apply
- Boom and articulating lifts: full body harness with a lanyard attached to the boom or basket anchor, never to an adjacent structure.
- Scissor lifts: stay inside the guardrails with gates and chains closed. That is the fall protection system.
- Keep at least 10 feet of clearance from overhead power lines up to 50 kV, and more above that voltage.
- Set up on firm level ground within the machine's rated slope, with outriggers deployed where the machine has them.
- Do the pre start function check at ground level and platform level before the first lift of the shift.
- Nobody stands or climbs on the rails, the toeboards or a plank laid across the basket.
Ask the crew
Three questions, answered out loud by name. This is the part that tells you whether anybody was listening.
- Which lift are you in today, and which rule applies to it, harness or guardrails?
- What is above your work area, and how close does the boom get to it?
- Is the ground under this machine what it looks like, or is there backfill under there?
Close with this
Feet on the floor of the basket, clearance overhead, firm ground under the wheels. That is the whole talk.
A talk nobody signed for is a talk that, as far as anybody can later prove, never happened. Use the free toolbox meeting sign in sheet in PDF, Word or Excel, or print the PDF above, which already has the signature lines on it.
Questions people ask
Do you need a harness in a scissor lift?
Generally no. A scissor lift platform has guardrails, and the guardrails are the fall protection under Subpart L, so the requirement is to stay inside them. Some employers and some manufacturers require a harness anyway, and if your site rule says wear one, wear one.
Do you need a harness in a boom lift?
Yes. 29 CFR 1926.453(b)(2)(v) requires a body belt or harness with a lanyard attached to the boom or basket. Attaching to an adjacent pole, structure or beam is specifically prohibited.
How close can a lift get to a power line?
Ten feet is the minimum for lines up to 50 kV, with greater distances required above that. Any part of the machine, the platform or the load counts, not just the boom tip.
