Gypsum is approximately 21 percent by weight chemically combined water which greatly contributes to its effectiveness as a fire resistive barrier. When gypsum drywall is exposed to fire, the water is slowly released as steam, effectively retarding heat transmission. Fire rated gypsum drywall is more fire resistant because it contains glass fiber reinforcement and other additives within its specially formulated gypsum core to help it hold up longer to a fire exposure. Fire  rated drywall is referred to as “Type X” and must be third-party certified by an independent testing and listing agency such as UL (Underwriters Laboratories Inc.) and ULC (Underwriters’ Laboratories of Canada) to meet the fire performance requirements prescribed in the ASTM C1396 (CAN/CSA-A82.27) Standard Specification for Gypsum Board. Types of Fire Rated Gypsum: Type X fire rated gypsum drywall that is 5/8 -inch (15.9mm) thick and installed on each side of nominal 2-inch x 4-inch (38x89mm) ...

1) What are the types of pump sets used and why in fire fighting? Jockey pump – used when there is a pressure drop. Electric pump – Main pump starts instantly in case of fire and will cutoff. Diesel pump – used in case of power shut down & Stand by Pump. 2) What is fire alarm check valve? It allows flow in one direction and prevents backward flow and with this gives signal to BMS with alarms. 3) What is FM-200 and where is it used? Heptafloropropane is colorless, liquefied compressed gas. It is stored as a liquid and dispensed into the hazard as a colorless, eclectically non-conductive vapor that is clear and does not obscure vision. It is used in communication rooms, electrical rooms, computer rooms etc.. 4) Types of detectors? Smoke, Heat & Multi detectors etc... 5) Do we use strainers in fire pumps? Why? No, we don’t use it because the water coming is portable usually only in cases where we are using river or lake water then we require strainers. Else we prefe...
