Scissor lifts are widely used in construction, maintenance, and industrial operations for safe elevation of workers and materials. However, despite their practicality, these machines pose potential hazards if not operated and maintained properly. Understanding these risks is the first step to ensuring on-site safety. Below are the most common scissor lift hazards and key prevention measures.
- Falls from Height
Falls are one of the leading hazards associated with scissor lifts. They often occur when workers fail to use fall protection equipment, step outside the lift’s platform, or operate the machine on uneven or unstable surfaces. A sudden platform tilt or collapse can also lead to catastrophic falls.
Prevention: Always wear a full-body harness attached to a secure anchor point on the lift. Never stand on the guardrails or lean over the platform edge. Before operation, inspect the work area to ensure the ground is level, firm, and free of debris. Avoid operating the lift in high winds or adverse weather conditions that could compromise stability. - Collisions with Obstacles
Scissor lifts, especially when elevated, have limited visibility, increasing the risk of collisions with overhead obstacles such as power lines, beams, or pipes. Ground-level collisions with structures or pedestrians are also common if the operator is distracted or unfamiliar with the machine’s maneuverability.
Prevention: Conduct a pre-operation site survey to identify and mark overhead hazards. Maintain a safe distance (at least 10 feet) from power lines. Assign a spotter when operating the lift in crowded or low-visibility areas. Ensure operators are fully trained on the lift’s controls and blind spots. - Equipment Malfunctions
Mechanical failures, such as hydraulic system leaks, faulty lift mechanisms, or brake issues, can cause the platform to drop suddenly or become stuck mid-air. These malfunctions often result from poor maintenance, worn parts, or improper use.
Prevention: Adhere to a regular maintenance schedule as recommended by the manufacturer. Before each use, perform a pre-start inspection, checking for hydraulic leaks, damaged cables, worn tires, and functional brakes. Never use a lift that shows signs of malfunction—tag it as out of service and report it immediately. - Overloading
Exceeding the scissor lift’s weight capacity can lead to platform instability, collapse, or component failure. Overloading often happens when workers carry excessive tools, materials, or additional personnel beyond the machine’s rated limit.
Prevention: Always check the lift’s load capacity label and never exceed it. Distribute materials evenly on the platform. Limit the number of workers on the lift to the manufacturer’s recommendation. Avoid storing heavy items on the platform during elevation. - Tip-Over Accidents
Scissor lifts can tip over if operated on sloped surfaces, soft ground, or uneven terrain. Sudden movements, such as rapid acceleration or deceleration, can also shift the center of gravity and cause a tip-over.
Prevention: Only operate the lift on level, solid ground. Use outriggers (if equipped) to enhance stability on uneven surfaces. Avoid sudden starts, stops, or turns, especially when the platform is elevated. Never drive the lift while the platform is raised higher than necessary.
Conclusion
Scissor lift hazards are largely preventable through proper training, thorough inspections, and adherence to safety protocols. By prioritizing operator training, regular maintenance, and site safety planning, businesses can minimize risks and ensure a safe working environment for all. Remember: safety is not an option—it’s a necessity when working with elevated equipment.
