Question 111General Subjects - QMED
70% to passWhich of the listed characteristics of fuel oil establishes the danger point as far as transferring, pumping, and firing procedures are concerned?
AViscosity
BFire point
CSpecific gravity
DFlash point
AI Explanation
The correct answer is D) Flash point. The flash point of a fuel oil is the most important characteristic that establishes the danger point for transferring, pumping, and firing procedures. The flash point is the lowest temperature at which the fuel can form an ignitable mixture with air. Fuel oils with a lower flash point are more prone to fire and explosion hazards, so their handling and use require greater safety precautions. The other options, such as viscosity, specific gravity, and fire point, are also important fuel oil characteristics, but they are not directly related to the key safety concern of the flash point, which is the primary factor in determining the danger level for fuel handling operations.
