Study Notes
Articulated Ladder Safety Guidelines
- Access roofs by stepping sideways onto the surface.
- Transport articulated ladders in a multi-ladder configuration, not single.
- Common materials for articulated ladders are fiberglass and aluminum.
Operating Configurations
- Use the stepladder configuration when working on stairs.
- Always maintain three points of contact while climbing.
- When configured as scaffolding, the height must not exceed three times the minimum width of the bottom support.
- The recommended angle of inclination is 75 degrees.
Inspection and Maintenance
- Regularly inspect ladders, not just those that have been used.
- Inspect ladders before each use, regardless of previous usage.
- To extend the lifespan of an articulated ladder, lubricate moving parts, clean after use, and protect from heat and corrosive substances.
Safety Precautions
- Environmental conditions like ice, rain, and snow significantly increase slipping hazards.
- Avoid using aluminum ladders near electrical sources or while operating power tools.
- The second step or rung from the top is generally the highest safe standing level in a stepladder configuration.
Climbing Guidelines
- Move the ladder only after descending first.
- When calculating weight support, include personal weight, tools, and supplies either on the ladder or being carried.
Injury Statistics
- More than 300 deaths occur each year due to ladder misuse.
- Over 160,000 injuries happen annually from not following ladder safety precautions.
Usage Restrictions
- Do not climb the inner section of the ladder when used as scaffolding if the outer section is not attached.
- It is not acceptable to stand above the highest recommended standing level, even if the ladder is too short.
Prohibited Practices
- Using any external objects such as boxes, barrels, or scaffolding to gain additional height is against safety guidelines.
