Portable Ladder Do's and Don'ts deserves a specific pre-task check because wrong ladder selection, poor footing, overreaching and damaged components can lead to falls. For this briefing, connect the topic to the exact equipment, work area and conditions the crew will face today, and agree a clear stop-work trigger before the task begins.
Process Safety Perspective
Fixed and portable ladder access to elevated process equipment should be assessed for compatibility with any required fall protection system — a fixed ladder exceeding the height threshold requiring a cage or climb-assist device should not be used without that system fully in place and functional.
Key Points
Position the base at one horizontal foot for every four feet of vertical height to the support point — commonly referenced as the 4-to-1 rule
Never carry tools or materials by hand while climbing — use a tool belt or a separate hoisting method to keep both hands free for climbing
Avoid leaning or overreaching to the side; reposition the ladder instead of extending beyond its stable working envelope
Best Practices
Inspect the ladder before each use for structural damage, loose rungs, or worn feet
Set up on firm, level ground and maintain the correct climbing angle throughout use
Maintain three points of contact continuously while climbing
Never stand on the top rung or any step explicitly designated as off-limits by the manufacturer
Face the ladder while climbing and keep body weight centered between the side rails
Secure the base or have it footed by another person when conditions warrant additional stability
Training Tip: Ask the crew to state the correct 4-to-1 setup angle rule for an extension ladder and demonstrate it.
Discuss with your crew: Is the ladder you're using currently set up at the correct 4-to-1 angle?
Scenario & Site Check
Discuss this scenario: A crew is about to start work where portable ladder do's and don'ts is relevant, but one condition in the work area has changed since the task was last performed. Ask the team what could make that change important, which control must be verified first, and who has authority to stop the job.
Field check: inspect the ladder, verify angle/footing, access height and three-point-contact expectations.
Evidence: confirm the applicable permit, inspection, label, test result, procedure or equipment status rather than relying only on memory.
Close-out question: “What would make us stop and reassess this task today?”
Reference Point
Use the current requirement that applies to your site. A useful starting point for Ladders is OSHA / NIOSH primary guidance. Company procedures, manufacturer instructions and local law may impose additional or more stringent controls.
