Question 415 Deck General

The correct answer is D) Toluene. Toluene is a flammable liquid and vapor that poses an explosion hazard when exposed to flame or other ignition sources. It is a common organic solvent used in various industrial and consumer products. Toluene has a low flash point, meaning it can ignite at relatively low temperatures, making it a significant fire and explosion risk. The other options are not considered explosion hazards when exposed to flame. Formic acid is a corrosive liquid, tallow is an animal fat, and nitrous oxide is a non-flammable gas, so they do not pose the same explosion risk as toluene under these conditions.
