Ladder Safety Toolbox Talk

Ladders are on almost every job, and that is exactly why people get careless with them. Most ladder falls happen from low heights on quick jobs that were never meant to take long. Five minutes setting the ladder up properly is a lot cheaper than months off work.

Takes about 8 minutes, plus a 5-question quiz.

What happened: a real incident

In February 2022, a man helping on a construction site in Cheltenham, Victoria, was climbing down an unsecured ladder leaning against a steel mezzanine frame when it moved. He fell more than 4 metres and died at the scene. In 2025 the building company was convicted and fined $270,000. The court found it could have provided a mobile scaffold, guard railing and proper stairs instead of relying on ladders.

Key points to read out

  1. Check the ladder before every use: feet, rungs, locks, rails and labels. If it is damaged, tag it out and get it off site.
  2. Use industrial rated ladders to AS/NZS 1892 only, and non-conductive fibreglass ladders anywhere near electrical work.
  3. Check the load rating on the label covers you, your tools and anything you carry up. Most falls happen when people go over it without thinking.
  4. Set extension ladders at 1 in 4: one out at the base for every four up, which is about 75 degrees.
  5. Extension ladders must stick out at least 1 m above the landing and be tied off or secured at the top.
  6. Secure the bottom too: tie it, use a stabiliser, or have someone foot it while the top is tied. Never stand it on bricks, offcuts or a pallet to make up height.
  7. Keep three points of contact while climbing. Carry tools in a belt or haul them up on a line, not in your hands.
  8. Face the ladder going up and coming down, and clean mud or grease off your boots and the rungs before you climb.
  9. Keep your belt buckle between the stiles. If you have to overreach, climb down and move the ladder.
  10. Never stand on the top cap or top step of a step ladder, or work off the top three rungs of an extension ladder.
  11. Open step ladders fully with the spreaders locked. Never lean a folded step ladder against a wall and climb it.
  12. Set up on firm, level ground, clear of doorways, traffic, plant and power lines. One person on a ladder at a time.
  13. Do not paint, patch or join ladders. Paint hides cracks, and homemade repairs fail without warning.
  14. Stop using a ladder outside in strong wind or heavy rain. A gust can move the ladder, or you, without warning.
  15. Ladders are for short, light jobs. If the task is long, heavy or needs both hands, use a platform ladder, mobile scaffold or EWP instead. Many principal contractors restrict ladder use on their sites, so check the site rules.

Questions to ask the crew

  1. Who checked their ladder before using it today, and what did you look for?
  2. Which job on this site right now would be safer from a platform than a ladder?
  3. Where do damaged ladders go, and who do you tell?
  4. What should you do if you can only reach the work by leaning out past the stiles?
  5. How is the bottom of your ladder secured today?

How to run this talk

  • Run it next to a real ladder you use on this job, not in the site office.
  • Set the ladder up badly first (wrong angle, untied, too short) and ask the crew to spot what is wrong.
  • Walk the 1 in 4 rule with a tape measure so everyone sees what 75 degrees looks like.
  • Point out two jobs on this site where a platform would be safer than a ladder and agree who will organise it.
  • Finish by doing a pre-use check out loud, then record attendance on the sign-in sheet with the date and topic.

Ladder Safety quiz

Ask these after the talk. Answers are underneath each question.

  1. You are setting up an extension ladder to reach a landing 4 m (about 13 feet) up. How far out should the base be?

    1. About 0.5 m (1.5 feet)
    2. About 1 m (3 to 4 feet), one out for every four up
    3. About 2 m (6 to 7 feet)
    4. It does not matter if someone foots it

    Answer: B. The 1 in 4 rule puts the ladder at about 75 degrees, the angle where it is least likely to slip out or tip back.

  2. How far should an extension ladder stick out above the landing you are stepping onto?

    1. It can stop level with the landing
    2. At least 1 m above the landing
    3. At least 300 mm above the landing

    Answer: B. The extra length gives you something to hold while you step on and off, which is when most ladder falls start.

  3. You need both hands to fit a heavy light fitting and it will take an hour. What should you use?

    1. A stepladder with a mate holding it
    2. An extension ladder tied off at the top
    3. A platform ladder, mobile scaffold or EWP

    Answer: C. Ladders are for short, light work where you can keep a hand on the ladder; long or two handed jobs need a working platform.

  4. You can only reach the work by leaning so your belt buckle is outside the stiles. What do you do?

    1. Lean out carefully, it is only for a second
    2. Climb down and move the ladder
    3. Stand on one leg to get extra reach
    4. Ask someone to hold the bottom harder

    Answer: B. Once your centre of gravity is outside the stiles the ladder can slide sideways, and footing it will not stop that.

  5. During your pre-use check you find a cracked stile on a fibreglass ladder. What happens next?

    1. Wrap it in tape and use it for light jobs only
    2. Paint over it so it does not get worse
    3. Tag it out of service and get it off site
    4. Use it, but only at low height

    Answer: C. A damaged ladder can fail under load without warning, and repairs or paint only hide the problem from the next person.

Questions about ladder safety

What is the 4 to 1 rule for ladders?

For every 4 units of height to where the ladder rests, the base should be 1 unit out from the wall, which sets the ladder at about 75 degrees. So a ladder resting 4 m (13 feet) up has its feet about 1 m (3 feet) out. Many ladders have an angle guide on the stile to help you check it.

How far should a ladder extend above the roof or landing?

At least 1 m above the landing, unless there is another secure handhold to step on and off. The ladder should also be tied or secured at the top so it cannot slide or tip.

How long can you work on a ladder?

There is no fixed time limit, but under the WHS laws a ladder should only be used when a safer option such as scaffolding or an EWP is not reasonably practicable. Ladders suit short, light jobs; long, heavy or two handed work needs a working platform.

How often should ladders be inspected?

Check the ladder yourself before every use, and have it formally inspected by a competent person on a regular schedule and after any incident. Anything damaged is tagged out and removed from site.

What the law says in Australia

Under the WHS laws, a ladder should only be used when a safer option such as scaffolding or an elevating work platform is not reasonably practicable. When a ladder is used, it must be secured so it cannot move, workers keep three points of contact, and the manufacturer's load rating must be followed.
