Not all ladders are created equal. Using the wrong type or duty rating can result in collapse, injury, or even fatal falls.
Why It Matters:
Ladders are rated for specific weight limits and uses. Choosing the wrong one — even for a short task — increases the risk of structural failure and serious injury.
Key Points:
- Duty rating refers to the maximum weight a ladder can safely hold (including the user, tools, and materials).
- Common ratings include:
- Type III (Light Duty – 200 lbs): Household use only.
- Type II (Medium Duty – 225 lbs): Light commercial use.
- Type I (Heavy Duty – 250 lbs): General construction.
- Type IA (Extra Heavy Duty – 300 lbs): Industrial use.
- Type IAA (Special Duty – 375 lbs): High-capacity tasks.
- Always inspect the label and weight capacity before use.
- Match ladder material (aluminum, fiberglass, wood) to task and environment (e.g., fiberglass near electricity).
✅ The right ladder supports the work — and you.
Ask the Crew:
- Do we know the duty rating of the ladders on site?
- Are we factoring in the total weight — including tools?
