FM GlobalProject Handling What design and installation standard does the client (orother stakeholders) want to work to? Nonstorage or Storage application?– Storage 20m2 or 1.5m high plastics or 3m ordinarycombustibles, protect according to Data Sheet 8-9 Occupancy specific data sheets; hydraulic or cutting oil,paper mills, woodworking, chemical plants, ignitable liquidsetcPUBLIC
FM GlobalNonstorage Protection FM Global Data Sheet 3-26 & 2-0 K80 sprinklers or water-mist is acceptable for HC-1occupancy Minimum K115 sprinklers in manufacturing areas (HC-2)– HC-3 occuancy, minimum K160 sprinklers– Ceiling heights 18 m, use K360 sprinklers Extended coverage (EC) heads allow sprinkler spacingsup to 36 m2, but beware:– Ceiling slopes 10 andPUBLIC– Obstructed ceiling construction

FM GlobalObstructions - Nonstorage Obstructions to sprinkler discharge “Individual obstructions” 1.2m wide Obstructions can only be consideredan “individual obstruction” if lessthan 3 diameters apart Spacing of sprinklers under non-flatobstructions should be 1.2m orinstall a flat barrierPUBLIC
FM GlobalStorage Protection Ceiling only or ceiling and in-rack sprinklers? Ceiling Only– FM Global Data Sheets 8-9 & 2-0– Storage sprinklers (“ESFR” or “large-drop”), largeorifice quick response storage heads– Flexible and economic– FM Global standards require minimum K160sprinklers for storage applicationsPUBLIC

FM GlobalStorage Protection Constraints of ceiling onlyprotection–––––Limited to 12 – 13.5m buildingsObstructionsLack of flue spacesSolid shelvesOpen top containers Must not stop water gettingto seat of firePUBLIC
FM GlobalStorage Protection Ceiling and in-rack automatic sprinklers (IRAS)– Can be used for any storage height– Very effective protection – suppression usually achieved– New options can keep water supply to the same size asfor ceiling onlyPUBLIC
FM GlobalStorage Protection In-rack sprinkler protection– Minimum K115 orifice heads, quick-response– Constraints Heads need to be located in the correct position in theracks Face sprinklers needed for some solutions Need to be removed and reinstalled if racks aremovedPUBLIC

FM GlobalNew storage protection options Factory Mutual began testing sprinklers in 1884 In the past 30 years, the focus has been on developingceiling sprinkler protection– FM Global began research into “large drop” sprinklers inthe 1970s and “ESFR” sprinklers in the 1980sPUBLIC
FM GlobalNew storage protection options Most testing of in-rack sprinkler designs was done in the1960s and 1970s using K80 and K115 heads Research into “ESFR” in-racks began in the late 2000s New protection options published in FM Global Data Sheet8-9 in May 2015 Alternative in-rack sprinkler designs can be used for allcommodities covered by Data Sheet 8-9 but must be openframe racks with adequate flue spaces (no solid shelvesand no open top containers)PUBLIC
FM GlobalK200 to K320 pendent sprinklers in the flue and face inevery transverse flue (at uprights only for face sprinklers ifno more than 2.6m apart)PUBLIC
FM GlobalNew storage protection options Vertical intervals of 9 m or 12 m 5 to 10 heads (5 in two adjacent rack) at 250 to 455LPM/head Treat top level of in-racks as the “floor” for the purposes ofdesigning the ceiling system Do not need to balance in-rack sprinklers with ceiling, noraccount for them flowing simultaneously 150 mm clearance needed from top of storage to sprinklerdeflectorPUBLIC

FM GlobalNew storage protection options Protection for unlimited building heights Lower cost with far fewer levels of in-rack sprinklers(every 9m or 12m) Reduced vulnerability to damage Efficient fire control Lower water demands Reduced water usage and environmental impactPUBLIC
