In a workplace, how should shop rags be disposed of to avoid fire hazards?

1. In plastic bins

2. In paper baskets

3. In metal containers

4. They can be thrown away anywhere

The correct answer is: In metal containers

Disposing of shop rags properly is essential to prevent fire hazards, especially when those rags have been used with flammable substances like oil or solvents. The correct choice, which is to dispose of them in metal containers, is based on their fire-resistant properties. Metal containers are sturdy and effectively contain any spontaneous combustion risk that oily rags may pose. When rags are placed in a metal container, it reduces the likelihood of ignition, as metal is non-combustible and can help prevent the rags from coming into contact with oxygen, which is a critical element needed for combustion. Other disposal options, such as plastic bins or paper baskets, may not offer the same level of protection against fire risks. Plastic containers can melt or ignite easily when exposed to heat, and paper baskets are highly combustible and can quickly catch fire if the rags inside are still warm or contain flammable materials. Additionally, tossing rags anywhere lacks the necessary precautions and increases the likelihood of a fire starting inadvertently. Proper disposal in a metal container is a clear best practice to maintain workplace safety.
