What should be kept away from heat, sparks, or open flame while working with cranes?

When working with cranes, it is crucial to keep cold weather starting fluid containers away from heat, sparks, or open flame. This is because cold weather starting fluid often contains highly flammable materials that can ignite easily. The vapor produced by these fluids is also ignitable and poses a significant fire hazard in the presence of any ignition source. Ensuring that these containers are stored away from potential sources of ignition protects workers and equipment from the risks associated with fire.

In contrast, while rope rigging materials and lubricants and oils can also present hazards, they do not typically have the same level of volatility as cold weather starting fluids. Rope rigging materials are generally more stable, though it is still wise to ensure they are kept in a clean and dry environment. Lubricants and oils should also be handled with care due to their potential to catch fire under specific conditions, but they do not pose the same immediate risk as flammable starting fluids. Crane operating manuals, on the other hand, do not have any flammable properties and are primarily important for the safe operation of the equipment. Therefore, the emphasis on keeping cold weather starting fluid containers away from heat sources is particularly important to ensure safety.
