Scissor lifts provide a valuable means of accessing elevated work areas. However, their use presents potential hazards if proper safety procedures are not followed. This section outlines key safety considerations for operating scissor lifts.
1. Pre-Operation Inspection:
Daily Inspection: Before each use, conduct a thorough inspection of the scissor lift. This includes:
Checking for leaks (hydraulic fluid, fuel).
Inspecting tires for damage. (normally non-pneumatic)
Verifying the functionality of all controls (ground and platform).
Testing the emergency lowering system.
Inspecting guardrails and toe boards.
Checking for any visible damage to the lift structure.
Checking for proper function of any safety devices, like tilt sensors.
Documentation: Record the inspection results in a daily inspection log.
2. Work Area Assessment:
Surface Conditions: Ensure the work surface is level, firm, and free of obstructions.
Overhead Hazards: Be aware of overhead power lines, pipes, or other potential obstructions.
Clearance: Verify that there is adequate clearance for the scissor lift to maneuver and operate safely.
Wind Conditions: Be aware of wind conditions, as strong winds can cause the lift to become unstable. Follow the manufacturers instructions for wind speed limitations.
Traffic Control: If working in a traffic area, establish appropriate traffic control measures.
3. Safe Operating Procedures:
Qualified Operators: Only trained and authorized personnel should operate scissor lifts.
Fall Protection: Always wear appropriate fall protection, such as a full-body harness and lanyard, when working on a scissor lift. Attach the lanyard to the designated anchor point on the platform.
Load Limits: Never exceed the lift's rated load capacity.
Proper Positioning: Position the lift on a stable surface and ensure that outriggers (if equipped) are properly deployed.
Avoid Movement While Elevated: Do not move the lift while the platform is elevated, unless the lift is specifically designed for this purpose.
Emergency Procedures: Be familiar with emergency lowering procedures and the location of emergency stop buttons.
No Climbing or Leaning: Never climb on or lean over the guardrails.
Keep Feet on the Floor: Always keep your feet firmly on the platform floor.
Avoid Scaffolding or other platforms: Never use the scissor lift platform as a base for scaffolding, ladders, or other elevating platforms.
4. Hazard Awareness:
Electrical Hazards: Be aware of the risks of electrocution from overhead power lines.
Tip-Over Hazards: Understand the factors that can cause a scissor lift to tip over, such as uneven surfaces, overloading, and strong winds.
Pinch Points: Be aware of pinch points and keep hands and feet clear of moving parts
5. Training:
Formal Training: All scissor lift operators must receive formal training on safe operating procedures.
Practical Training: Practical, hands-on training is essential to ensure that operators are competent in operating the lift safely.
Refresher Training: Regular refresher training is recommended to reinforce safe operating practices.
