Which action should be taken to prevent fire hazards?

To prevent fire hazards, it is crucial to dispose of rags promptly, especially if they are soaked in flammable substances like oils or solvents. Rags left in a pile can increase the risk of spontaneous combustion, as the heat generated during the decomposition of organic materials can ignite these flammable substances. By ensuring that rags are disposed of immediately and properly, you significantly minimize the risk of fire hazards in the work environment.

In contrast, keeping new rags nearby could potentially lead to a buildup of combustible materials. Wiping up water spills is important for preventing slips but does not directly relate to fire prevention. Similarly, cleaning metal chips from a machine is a good safety practice for preventing accidents and improving machine efficiency, but it does not address fire hazards in the same way as the proper disposal of flammable rags.
