Study Notes
Signage and Manuals
- Signs and decals must remain free of dust and grease for readability.
- Torn or damaged signs require immediate replacement.
- Manufacturer must provide a manual detailing:
- Description, specifications, capacities of the platform
- Operating pressure for hydraulic/pneumatic systems
- Operation and maintenance instructions including daily, weekly, monthly inspection checklists
- Information on replacement parts
- Manual must be stored in a weatherproof container on the equipment
Operator Familiarity and Safety Practices
- Operators must know:
- Manufacturer’s operating manual
- Warning and caution signs on the equipment
- Locations of emergency controls and procedures
- Daily maintenance checks to conduct
- General safety guidelines for Electronic Work Platforms (EWPs) and Aerial Devices:
- Check for overhead power lines before movement; coordinate with utility owners for de-energization if necessary.
- Wear full-body harness and tie off to designated points while in motion.
- Do not leave machines unattended without securing or locking them.
- Avoid exceeding rated working load (RWL); keep load below 2/3 of RWL when possible.
Equipment and Structural Safety
- Ensure all controls are clearly labeled indicating action and direction.
- Keep guardrails in good condition; secure gates before moving platforms.
- When guardrails are below 39 inches, use an approved personal fall protection system.
- Ladders used to access platforms must have rungs no more than 12 inches apart.
- Platforms exceeding 60 inches in height require safe emergency lowering mechanisms.
- Powered elevating platforms must feature upper and lower control devices, clearly marked and guarded against accidental activation.
- Emergency stop devices are mandated at upper controls.
Platform Specifications
- Elevating work platforms must have:
- Toeboards at least 4 inches high on sides and ends (except at access openings).
- Hinged trap access doors where applicable.
- Minimum platform width of 16 inches.
- Guard and stability requirements apply to all rotating shafts, gearing, and moving parts.
- Usage on inclined surfaces is only permitted if manufacturer-approved; stability procedures must be documented in the manual.
- Lower-level controls should only operate with permission from on-device personnel, except in emergencies.
Aerial Device Movement and Safety
- Inspect booms and outriggers before moving aerial devices to ensure they are cradled and stowed.
- Employees in elevating aerial devices must be secured with safety belts, body belts, or harnesses attached to safety straps or lanyards.
- Safety belts/body belts may be used for positioning or fall restraint, but not in fall arrest systems. They must limit free fall to no more than 2 feet.
- Body harnesses in fall arrest systems must utilize lanyards with deceleration devices, limiting arresting force to 1,800 pounds and maximum free fall to 6 feet.
Daily Inspections
- Conduct daily inspections and use specific checklists for aerial lift equipment and scissor lifts.
- Only operate equipment confirmed to be in safe working order; do not use defective machinery.
