Effectively using a wooden extension ladder involves properly securing it and setting the correct angle to ensure stability and safety during use.
Key Steps for Using a Wooden Extension Ladder
Using an extension ladder safely requires attention to placement and stability. Based on standard safety guidelines, follow these essential steps:
Securing the Ladder
Proper securing prevents the ladder from shifting, sliding, or tipping while you are on it.
- Secure the top, bottom, or both: Always aim to fasten the ladder securely at its resting points. This could involve tying off the top to a stable structure or staking/weighting the base.
- Have someone hold it: If securing at the top or bottom is not possible, have another person stand at the base of the ladder and hold it firmly in place while it is in use.
Setting the Correct Angle
The angle of the ladder against the structure is crucial for preventing it from sliding out at the bottom or falling backward.
- Use the 1:4 ratio: Position the base of the ladder using the 1:4 rule. For every 4 metres of vertical height the ladder reaches up the wall or structure, the base should be placed 1 metre away from the base of the structure.
- Example: If the top of the ladder is resting against a wall at a height of 8 metres, the base of the ladder should be placed 2 metres away from the wall (8 metres height / 4 = 2 metres base distance).
This ratio ensures the ladder is neither too steep (risk of falling backward) nor too shallow (risk of sliding out at the base).
Summary of Ladder Placement
| Action | Detail | Requirement |
|---|---|---|
| Securing | Fasten at top, bottom, or both. | Essential for stability |
| If unable to secure, have someone hold the ladder. | Safety backup | |
| Angling | Position base 1 metre away from structure for every 4 metres of height (1:4). | Prevents slipping |
Always inspect your wooden extension ladder before each use for any signs of damage, decay, or loose components. Proper maintenance and correct usage are paramount for safety.
