Why can an empty gasoline tank be considered more dangerous than a full one?

• A. It can contain explosive vapors
• B. It is easier to transport
• C. It is less affected by heat
• D. It has a lower risk of leakage

Answer: (A)

An empty gasoline tank can be considered more dangerous than a full one because it can contain explosive vapors. When a gasoline tank is empty, it is not filled with liquid fuel, but there may still be residual vapors present. These vapors are highly flammable and can ignite if exposed to a spark or heat source, posing a significant fire and explosion hazard. While a full tank does contain gasoline, which is also flammable, the liquid can reduce the amount of vapor that escapes into the air compared to an empty tank where vapors can accumulate. This makes the potential for dangerous concentrations of flammable vapors much higher in an empty tank. The other options primarily address considerations unrelated to the explosive risks associated with vapors. For instance, ease of transport or considerations about heat and leakage do not directly relate to the immediate hazards posed by the presence of flammable vapors and their potential for ignition.
