The safest ladder setup starts with the right angle — too steep or too shallow and you’re asking for a fall.
Why It Matters:
Ladders that are not positioned correctly can tip backward, slide out at the base, or collapse under the user. The 4-to-1 rule helps ensure your ladder stays secure while climbing and descending.
Key Points:
- Use the 4-to-1 rule: For every 4 feet of ladder height, set the base out 1 foot from the wall or support.
- The ladder should lean at approximately a 75-degree angle.
- Stand at the base — if your arms are fully extended and your hands just touch the ladder’s rungs, the angle is correct.
- Secure the top and bottom if necessary to prevent movement.
- Never place ladders at extreme angles or use them sideways.
✅ The right angle keeps you upright and injury-free.
Ask the Crew:
- Are all ladders set using the 4-to-1 rule?
- Is any ladder too steep or too flat to be safe?
