Firefighter 1C Wildland Practice Exam

The recommended fuel mixture for a drip torch is _________________

1. 2 parts gasoline to 1 part diesel

2. 2 parts kerosine to 1 part diesel

3. 2 parts diesel to 1 part kerosine

4. 2 parts diesel to 1 part gasoline

The correct answer is: 2 parts diesel to 1 part gasoline

The appropriate fuel mixture for a drip torch is comprised of two parts diesel to one part gasoline. This combination is favored for several reasons. Diesel fuel has a higher flash point than gasoline, which makes it safer to handle and reduces the risk of accidental ignition. When mixed with gasoline, which burns more readily, the mixture produces a more efficient fuel for controlled burns. The use of this specific ratio also helps in achieving a more consistent burn, allowing firefighters to effectively manage fire spread during prescribed burns or controlled operations. Since diesel produces a more stable flame, it aids in reducing the likelihood of flare-ups, making it a preferred choice for fire management professionals working in wildland areas.
