Best answer
The correct option is (a) True

For explanation: A fast acting valve is an isolating or segregating device used for isolating the hazards with a barrier. The purpose of this automatic fast acting valve is to seal off the area of material handling system from spreading of fire. It is intended to prevent the flame front and isolate the part of equipment in the case of rapid burning.
