Electrical Fault - ANSWER Electrical failure such as short circuit, loose connection, overload, or arcing that may start a fire. 13. Importance of Fire Protection Systems - ANSWER Fire protection systems are essential for the safety, reliability, and sustainability of industrial operations. 14. Life Safety - ANSWER Protects workers, operators, and emergency responders from injury or death during fire incidents. 15. Asset Protection - ANSWER Prevents or reduces damage to machinery, buildings, and critical equipment. 16. Business Continuity - ANSWER Reduces downtime, production losses, and recovery costs after a fire incident. 17. Legal Compliance - ANSWER Helps the plant meet safety regulations and avoid penalties, violations, or shutdowns. 18. Environmental Protection - ANSWER Limits the release of hazardous chemicals and pollutants during fire emergencies. 19. Fire loss data reveals that in buildings equipped with automatic sprinklers, about _____percent of all fires were controlled or extinguished by the sprinkler system. - ANSWER Ninety-four 20. Thermally sensitive devices such as fusible links keep most sprinklers closed and when heat from a fire affects these devices: - ANSWER sprinklers closest to the fire activate automatically 21. Which automatic sprinkler system is continually charged with water under pressure that discharges immediately when heat from a fire activates one or more sprinklers? - ANSWER Wet pipe sprinkler system 22. Which automatic sprinkler system consists of open sprinklers attached to unpressurized dry pipes? - ANSWER Deluge sprinkler system 23. Which automatic sprinkler system is continually charged with air under pressure combined with a detection system that controls the operation of the waterflow control valve? - ANSWER Combined dry pipe and preaction sprinkler system 24. Which automatic sprinkler system is designed to be operated repeatedly in response to a detection device and shuts on and off based on the demand indicated by the detection device? - ANSWER Multicycle sprinkler system 25. While maintaining a minimum required residual pressure in the system, a water supply must be able to deliver the required volume of water to: - ANSWER the highest or most remote sprinkler in a structure 26. What is the purpose of fire department connections as part of automatic sprinkler systems? - ANSWER Boost the pressure of the primary water supply 27. Which type of valve is a gate valve that has a yoke on the outside with a threaded stem or screw? - ANSWER Outside stem and yoke 28. Which operating valve is located on the riser and used to flow water for testing the waterflow alarm? - ANSWER Alarm-test valves 29. Which valve is usually a globe valve and may sometimes be found at a remote location within a sprinkler system? - ANSWER Inspector's test valve 30. The pipe schedule table method is limited to: - ANSWER light and ordinary hazards 31. Which type of sprinkler is recessed and covered with a removable decorative cover plate that releases when exposed to a specific level of heat? - ANSWER concealed 32. The maximum spacing between sprinklers in residential systems is: - ANSWER 12 feet (3.5 m) 33. Active Design Approach - ANSWER A design approach that used mechanical systems to prevent smoke and gas movement by exhausting, pressurizing, and, in particular situations, opposing the smoke with forced air 34. Buoyancy Forces - ANSWER Upward forces that cause hot gases to rise when fire plume temperatures are higher than the surrounding air 35. Elevator hoistway pressurization - ANSWER A mechanical method of smoke control in which 100% outdoor air is pumped into the elevator hoistway at an increased pressure, forming a pressure barrier that prevents smoke and gases from entering the elevator shaft. 36. Floating Zone/Floor-by-floor Pressurization - ANSWER A mechanical method of smoke control in which 100% outdoor air is pumped onto the floors above and below the fire floor, forming a pressure sandwich or barrier around the fire and mechanically relieving or exhausting the air from the fire floor(s); this method is most successful when all non-fire floors are pressurized. 37. Passive Design Approach - ANSWER A design approach that uses fixed barriers, such as walls, bulk-heads, doors, partitions, high ceilings, and sealed floor openings, to prevent smoke and gas movement
