Ladder and fall safety on a DIY jobsite

A ladder is a way to reach a place, not a work platform. Most ladder injuries come from poor setup, overreaching and using the wrong ladder for the job.

Choose the right ladder

• Check the duty rating against your weight plus tools and materials.
• Use a non-conductive ladder, such as fibreglass, near any electrical risk. Never use a metal ladder near overhead lines.
• Inspect it first: bent rails, loose rungs, cracked feet or missing labels mean do not use.

Set it up

• Ground must be firm and level. Never prop a ladder on boxes or bricks.
• Place a straight ladder at about a 4-to-1 angle (one foot out per four feet up) and extend it about three feet above the landing.
• Secure the top or have someone hold the base, and keep doors and traffic clear.

Use it

• Face the ladder and keep three points of contact.
• Keep your belt buckle between the rails. If you must lean out, climb down and move it.
• Do not carry heavy loads up by hand; hoist them or use a tool belt.

When a ladder is the wrong answer

Roof work, long jobs overhead and edges more than a short height up usually call for scaffolding, a platform ladder, or a trade with fall protection. Roofing is one job many owners are wise to hand over.

Always check the project drawings and specification, and confirm requirements with the engineer of record and the local authority.

Quick answers

• How far out should a straight ladder sit? A common rule from OSHA guidance is one foot of horizontal distance for every four feet of height. Check the ladder labels as well.
• How far should it extend above the roof edge? About three feet above the landing so you can grip it when stepping on or off.
• Can I use the top step of a stepladder? No. Manufacturers label the top step and cap as not for standing. Use a taller ladder.
• When should I use scaffolding instead? For longer work at height, when you need both hands and a stable platform, or when the job cannot be reached safely from a ladder.
