Why is it dangerous to smoke near tanks containing flammable gases?

Smoking near tanks containing flammable gases is dangerous because the open flame can ignite the gases, leading to explosions or fires. Flammable gases can accumulate in the air, and even a small spark from a cigarette can trigger a catastrophic reaction. Additionally, the intense heat produced by combustion can cause nearby tanks to rupture or explode, posing a severe risk to both individuals and the surrounding environment. Safety protocols typically prohibit smoking in such areas to prevent these hazardous incidents.
