Which items should never be used near an open flame?

Using gasoline, paint, and kerosene near an open flame is extremely dangerous due to their highly flammable nature. These substances can easily ignite and cause fires or explosions if they come into contact with a flame or even a spark. Gasoline is especially volatile, while paint and kerosene can emit vapors that are also combustible. It is crucial to store and handle these materials in environments that are free from any sources of ignition to ensure safety.

In contrast, the other items listed, such as food and beverages, tools and equipment, and PPE gear, are not inherently flammable to the same extent. While it is advisable to exercise caution with all items in proximity to an open flame, the risk presented by gasoline, paint, and kerosene makes them particularly hazardous and thus should never be used near any open flame.
