Question 155Steam Plants - Assistant Engineer
70% to passWhich of the following fuel oil characteristics establishes the danger point when transferring, pumping, and firing procedures are concerned?
AViscosity
BFlash point
CSpecific gravity
DFire point
AI Explanation
The correct answer is B) Flash point. The flash point of a fuel oil is the key characteristic that establishes the danger point when transferring, pumping, and firing procedures are concerned. The flash point is the lowest temperature at which the fuel can vaporize to form an ignitable mixture in air. Fuels with a low flash point are more prone to catching fire and explosion hazards, so this is a critical safety consideration for any fuel handling operations. In contrast, viscosity, specific gravity, and fire point are not the primary factors determining the explosion and fire risks.
