a If the use of a fire blanket is common in your country, be sure that you know how to use it properly. The U.S. National Fire Protection Association states: “It should be emphasized that . . . fire blankets are of secondary importance. They should be used only when immediately at hand. . . . Improper use of fire blankets can increase the severity of smoke and fire injuries if the blanket funnels smoke towards the face or if the blanket is not removed after the flames have been extinguished.”
