Lifts of materials such as oxygen, acetylene, propane, or gasoline in bottles, cans, tanks, or properly secured in racks designed for lifting by a crane are considered?

• A. Complex lift
• B. Simple lift
• C. Routine lift
• D. Hazardous lift

Answer: (A)

Lifts involving cylinders of oxygen, acetylene, propane, or gasoline require more planning and rigging than a straightforward lift. These are hazardous, pressurized containers; if a valve is damaged, the cylinder can leak or become a dangerous projectile, and improper handling can lead to leaks or fire hazards. Even when kept in racks built for crane handling, the load must be kept upright, secured against rolling, and protected from impact with the right cradles, slings, chains, or straps, plus appropriate spacing and precautions for valve protection. This combination of hazard, need for specialized securing, and the extra planning that goes into a safe lift is why it’s categorized as a complex lift. Simple or routine lifts imply uncomplicated, non-hazardous loads with standard rigging, while a hazardous lift is a broad safety label that doesn’t alone capture the required rigging complexity and coordination for a safe, properly engineered lift.
