Question 4515 Deck General

The correct answer is A) within 50 feet. The prohibition on smoking, flames, or sparks within 50 feet of a refueling area or fuel facility is a standard safety regulation to prevent the risk of fire or explosion during refueling operations. This regulation applies regardless of whether the refueling is actively taking place or not, as the hazardous conditions exist within that 50-foot radius. The other options are incorrect because B) is too narrow (it should be prohibited even when not actively refueling), C) is irrelevant (a helodeck is not a refueling area), and D) is too broad (the 50-foot rule is the standard regulation).
