Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

What should be done with rags used for cleaning up combustible substances?

1. Store them immediately in a closed container

2. Leave them in an open pile

3. Dispose of them promptly

4. Leave them on the workbench for later use

The correct answer is: Dispose of them promptly

The most appropriate action regarding rags used for cleaning up combustible substances is to store them immediately in a closed container. When rags become saturated with flammable or combustible materials, they pose a significant fire hazard due to the potential for spontaneous combustion. By placing these rags in a closed container, you mitigate the risk of ignition and reduce the potential for a fire to start. Using a closed container not only helps in safely containing any combustible materials but also prevents the spread of fumes and keeps the area organized and safer. This practice aligns with proper safety protocols and standards in manufacturing environments, which prioritize the prevention of accidents and maintaining a safe workplace. Leaving rags in an open pile, disposing of them promptly, or leaving them on the workbench for later use does not adequately address the potential hazards associated with combustibles. Such practices could lead to an increased risk of fire, making immediate and safe storage the best practice.
