TL;DR
This working at height toolbox talk teaches the avoid, prevent, minimise approach: do the job from the ground where you can, use guardrails and platforms where you can't, and use and inspect fall protection where a fall risk remains. Falls can be serious even from low levels.
This working at height toolbox talk is for crews who work on roofs, mezzanines, racking, platforms, vehicles, ladders or anywhere with an edge or a fragile surface. Allow about ten minutes, because it works best when the crew talks through a real job you have coming up. They should leave able to spot work at height and know the order of controls.
Why does working at height safety matter?
Falls from height are one of the deadliest hazards at work. OSHA's fall prevention campaign reports that in 2024 there were 389 fatal falls to a lower level out of 1,034 construction fatalities, based on BLS data. NIOSH notes construction has the highest rate of fall-related deaths, and that falls are its leading cause of worker deaths.
It doesn't take a big drop. The UK HSE defines work at height as any place where a person could fall a distance liable to cause injury if there were no precautions. HSE also says working at height remains one of the biggest causes of fatalities and major injuries, with falls from ladders and through fragile surfaces among the common cases.
Rules differ by country (OSHA in the US, the Work at Height Regulations in the UK), so check the rules where you work.
Talking points for your working at height toolbox talk
- Avoid it first. Ask whether the job can be done from the ground. Long-handled tools, lowering a light fitting or pre-assembling at floor level all remove the fall risk entirely.
- Prevent falls with collective protection. Where you can't avoid height, use guardrails, scaffolds, mobile platforms or scissor lifts. These protect everyone without anyone having to clip on.
- Minimise the fall if risk remains. Harnesses, lanyards and nets reduce the distance and consequences of a fall. They only work when fitted, connected to a suitable anchor and used every time.
- Inspect fall protection before use. Check webbing for cuts, burns and fraying, stitching for damage, and hooks and buckles for wear. Any harness that has arrested a fall comes out of service.
- Never remove guardrails or covers without authorization. A missing rail or an uncovered hole is a trap for the next person. If something must come off, it's controlled and replaced before you leave.
- Watch for fragile surfaces. Skylights, roof sheets and ceiling tiles can look solid. Never step on a surface unless you know it will take your weight.
- Stop and ask if the plan doesn't fit. If the access you were given won't reach, the weather turns or the conditions differ from the plan, stop and talk to your supervisor. Don't improvise.
Example to share with the crew
For example, a two-person crew is replacing a sensor on top of a delivery trailer. It's only a few metres up, so they climb on using the trailer's side and work near the edge without any barrier. One steps backwards to get a better angle and goes over the side onto the yard.
A platform or the dock's fall-arrest gantry was available. Ask the crew which "quick jobs" on site put them near an unprotected edge.
Working at height checklist
- Task reviewed: can any of it be done from the ground?
- Right access equipment chosen (platform, scaffold, lift, or ladder only for short low-risk work)
- Guardrails, edge protection and hole covers in place and secure
- Fragile surfaces identified and marked or covered
- Harnesses and lanyards inspected before use, with a suitable anchor point
- Area below barricaded against falling objects
- Rescue plan in place for anyone working in a harness
- Weather and lighting checked for outdoor work
Questions to ask the crew
- What work at height do we do that could be done from the ground?
- Where on this site could someone step onto a fragile surface without realizing?
- If you found a guardrail missing, what would you do before carrying on?
How to close the talk
The takeaway from this working at height toolbox talk: avoid height where you can, protect the edge where you can't, and stop if the plan doesn't match the job. Report missing guardrails, damaged harnesses or unsafe access to your supervisor before work starts. Pair this with the ladder safety talk, or find more safety talk topics here.

Frequently asked questions
What should be covered in a working at height toolbox talk?
When work counts as work at height, the avoid, prevent, minimise approach, guardrails and platforms before harnesses, pre-use checks of fall protection, never removing guardrails or covers, and stopping when the access plan doesn't fit.
What counts as working at height?
The UK HSE defines it as work in any place where, without precautions, a person could fall a distance liable to cause personal injury. That includes low heights and fragile surfaces, not just roofs and scaffolds.
Is a harness the best fall protection?
Not first. HSE advises collective protection such as guardrails and scissor lifts before personal protection like a harness, because collective measures don't rely on each person using them correctly.
