Which items are prohibited within 50 feet of a cold refueling operation?

• A. Smoking
• B. Open Flames
• C. Spark-Producing Items
• D. All Of The Above

Answer: (D)

During cold refueling, the focus is on preventing ignition of fuel vapors. The area within 50 feet is treated as a high-risk zone because vapors can travel and ignite from various ignition sources. Smoking introduces a continuous flame and heat source, which is easily capable of igniting vapors. Open flames are prohibited for the same reason—any flame near fuel vapors can cause a flash fire or explosion. Spark-producing items are also not allowed because a spark from electrical equipment, tools, or metal-to-metal contact can ignite vapors instantly. Since all three categories pose ignition risks, all of the above are prohibited within 50 feet of a cold refueling operation.
