Question 745 Deck General

The correct answer is B) -20°F. According to the Chemical Data Guide for Hazardous Materials, the flash point for the flammable liquid piperylene, which is a grade B flammable liquid, is -20°F. This is the temperature at which the liquid will produce enough flammable vapors to ignite when exposed to an ignition source. The other options are incorrect because: A) the flash point is available in the Chemical Data Guide, C) 108°F is too high for a grade B flammable liquid, and D) 43°C is equivalent to 109.4°F, which is also too high.
