Wildland Firefighting Practice Exam

When approaching a propane tank fire, it is crucial to approach from the sides rather than from the front, top, or bottom. This is because propane tanks typically have a pressure relief valve located on the top, which can vent gas in the form of a flame or a puff of propane if the tank is under extreme heat or pressure. Approaching from the front can put you directly in the path of this venting, increasing the risk of injury from flames or explosive pressure release.

By approaching from the sides, you effectively stay out of the immediate danger zone of the pressure relief valve and any potential fireball that may occur if the flame ignites the gas. This tactic allows firefighters to maintain a safe distance while assessing the situation, providing the advantage of observing the flames and smoke without being in direct line of fire. Understanding the structure and safety mechanisms of propane tanks is critical for safely managing incidents involving them, which highlights the importance of proper approach techniques in firefighting.
