Which statement defines an open fire?

• A. A fire you can see the source of
• B. A fire you cannot see the source
• C. A fire that cannot be extinguished
• D. A fire that is fueled by gas

Answer: (A)

Open fire is defined by the flame being exposed and you being able to see where the burning is coming from. When the fire’s source is visible, there’s no enclosing chamber or cover around the flame, so you can observe the fuel and the flame directly. This visibility matters for safety and firefighting approaches, since open flames react to air directly and aren’t hidden behind walls or housings. That’s why the correct description is a fire you can see the source of. The other ideas don’t define open fire: a fire whose source you can’t see is hidden; whether a fire can be extinguished isn’t part of this definition; and being gas-fueled speaks to the fuel, not whether the flame is visible or exposed.
