Safety Trained Supervisor in Construction (STSC) Practice Exam

A container for gasoline should be:

1. Made of plastic with a regular cap

2. Metal with UL specified non-spill cap

3. Any color as long as it's clearly labeled

4. Store in standard buckets

The correct answer is: Metal with UL specified non-spill cap

The correct choice highlights the importance of using an appropriate type of container for gasoline to ensure safety in construction and other environments where flammable materials are present. Gasoline is a volatile substance that can easily ignite, so the container needs to be specifically designed to handle its properties safely. A metal container that has a UL (Underwriters Laboratories) specified non-spill cap is crucial because it minimizes the risk of spills and leaks, which can lead to fire hazards. UL certification indicates that the container has been tested under specific safety standards for flammable liquids. The non-spill cap ensures that even if the container is knocked over or jostled, it won't release its contents, further reducing the risk of igniting gasoline vapors. In contrast, other options present less safe practices. Using a plastic container with a regular cap might not withstand the stresses associated with storing a flammable liquid like gasoline, potentially leading to leaks or failures. The indication that any color is acceptable as long as it’s labeled overlooks the importance of using a container designed specifically for hazardous materials, which is not just about visibility but also about the material and construction of the container itself. Finally, storing gasoline in standard buckets lacks the necessary safety features, making them unsuitable for flammable liquids.
