Scenario 11-1: The July 6, 2013, railway disaster in Lac-Mégantic, Quebec highlighted the danger that businesses can face when they are located close to rail lines, especially in the event of a derailment. One hundred and fifteen businesses were severely affected when an unattended train carrying crude oil derailed and crashed in the downtown area. Thirty buildings were completely destroyed, much of the downtown infrastructure (roads, utilities, and so on) was destroyed or severely damaged, and over 40 people died with many others seriously injured. While a runaway train may seem to be a rare occurrence, Canadian statistics indicate that, based on data from 2007-2011, on average there are 58 derailments annually, although not all of these involve dangerous goods.
-If there is the opportunity to do so safely,what type of extinguisher should be used to fight an oil-based fire caused by sparks from the derailment?

Question

Quizplus · Accepted Answer

When dealing with an oil-based fire, powder or dry chemical extinguishers should be used. Water should never be used to fight an oil-based fire as it can spread the flames and cause the fire to become worse. CO₂ and halon extinguishers are effective for electrical fires but are not recommended for oil-based fires.
