What should you do to secure safety when using extension ladders?
What should you do to secure safety when using extension ladders?
- Place ladders on a firm, level surface and ensure the footing is secure.
- Erect extension ladders so that the upper section rests on (e.g., in front of) the bottom section. This means the bottom section "faces" a wall or other supporting surface (see figures below).
-
Raise and lower ladders from the ground. Ensure that locking ladder hooks are secure before climbing.
- Erect ladders so that a minimum of 1 m (3 ft) extends above a landing platform. Tie the top at support points.
- Where a ladder cannot be tied off at the top, station a person at the foot to prevent it from slipping. This method is only effective for ladders up to 5 m (16 ft) long. The person at the foot of the ladder should face the ladder with a hand on each side rail and with one foot resting on the bottom rung.
- Leave all tie-off devices in place until they must be removed before taking the ladder down.
- Maintain the minimum overlap of sections as shown on a ladder label. Refer to safety regulations.
What should you avoid when using extension ladders?
Do not use ladders near electrical wire. Do not set up or take a ladder down when it is extended. Do not overextend. Maintain minimum overlap of sections.
What should you do to avoid overexertion while setting up an extension ladder?
When setting up an extension ladder, use the following method to avoid straining muscles or losing control of a ladder. With ladders weighing more than 25 kg (55 lb), or where conditions complicate the task, have two persons set up a ladder, step by step, as follows:
- Lay a ladder on the ground close to intended location.
- Brace ladder base using helpers' feet.
- Grasp the top rung with both hands, raise the top end over your head and walk toward the base of a ladder. Grasp the centre of the rungs to maintain stability.
- Move the erect ladder to the desired location. Lean it forward against the resting point.
- Do not climb higher than the fourth rung from the top of a ladder.
- Do not use ladders on ice, snow or other slippery surfaces without securing ladders' feet.
- Do not extend top section of a ladder from above or by "bouncing" on a ladder.
- Do not leave ladders unattended.
One person can erect a short ladder, step by step as follows:
- Place the bottom of a ladder firmly against the base of a building or stationary object.
- Lift the top of ladder, and pull upwards to raise a ladder to a vertical position.
- Transfer a ladder to its required position when it is erect.
- Keep a ladder upright and close to the body with a firm grip.
