When an oil fire has been extinguished, the surface of the oil should be kept covered with foam to prevent __________.

🔍 Key Concepts

• How foam works on a flammable liquid (oil) fire • The fire triangle: fuel, heat, and oxygen (air) • What happens to vapors from hot oil after the visible flames go out

💭 Think About

• After an oil fire is put out, what is still present that could allow the fire to start again? • Does foam mainly protect you from fumes, heat, or the possibility of the fire re-lighting? • Which option best matches how foam forms a blanket over the oil and what that blanket actually stops?

✅ Before You Answer

• Identify which choice deals with reignition rather than health hazards or temperature alone. • Think about the role of oxygen (air) in continuing or restarting combustion. • Ask: which choice describes the main safety reason firefighters keep a foam blanket on a flammable liquid after flames are out?
