Today's Challenges
 Business is global
 Supply chain risks are growing
 Business is changing
–

Building design, larger and higher
New storage solutions
Increasing amounts of plastics
Integration of operations
 Understanding the client’s
operations and innovation in
insurance coverage and
engineering solutions are critical

Project Handling
 What design and installation standard does the client (or
other stakeholders) want to work to?
 Nonstorage or Storage application?
– Storage >20m2 or >1.5m high plastics or >3m ordinary
combustibles, protect according to Data Sheet 8-9
 Occupancy specific data sheets; hydraulic or cutting oil,
paper mills, woodworking, chemical plants, ignitable liquids
etc
PUBLIC
FM Global
Nonstorage Protection
 FM Global Data Sheet 3-26 & 2-0
 K80 sprinklers or water-mist is acceptable for HC-1
occupancy
 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 spacings
up to 36 m2, but beware:
– Ceiling slopes >10°and
PUBLIC
– Obstructed ceiling construction

Obstructions - Nonstorage
 Obstructions to sprinkler discharge
 “Individual obstructions” ≥1.2m wide
 Obstructions can only be considered
an “individual obstruction” if less
than 3 diameters apart
 Spacing of sprinklers under non-flat
obstructions should be 1.2m or
install a flat barrier
PUBLIC
FM Global
Storage 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”), large
orifice quick response storage heads
– Flexible and economic
– FM Global standards require minimum K160
sprinklers for storage applications

Storage Protection
 Constraints of ceiling only
protection
–
–
–
–
–
Limited to 12 – 13.5m buildings
Obstructions
Lack of flue spaces
Solid shelves
Open top containers
 Must not stop water getting
to seat of fire
PUBLIC
FM Global
Storage 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 as
for ceiling only

Storage Protection
 In-rack sprinkler protection
– Minimum K115 orifice heads, quick-response
– Constraints
• Heads need to be located in the correct position in the
racks
• Face sprinklers needed for some solutions
• Need to be removed and reinstalled if racks are
moved

New storage protection options
 Factory Mutual began testing sprinklers in 1884
 In the past 30 years, the focus has been on developing
ceiling sprinkler protection
– FM Global began research into “large drop” sprinklers in
the 1970s and “ESFR” sprinklers in the 1980s
PUBLIC
FM Global
New storage protection options
 Most testing of in-rack sprinkler designs was done in the
1960s 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 Sheet
8-9 in May 2015
 Alternative in-rack sprinkler designs can be used for all
commodities covered by Data Sheet 8-9 but must be open
frame racks with adequate flue spaces (no solid shelves
and no open top containers)
PUBLIC
FM Global
K200 to K320 pendent sprinklers in the flue and face in
every transverse flue (at uprights only for face sprinklers if
no more than 2.6m apart)
PUBLIC
FM Global
New storage protection options
 Vertical intervals of 9 m or 12 m
 5 to 10 heads (5 in two adjacent rack) at 250 to 455
LPM/head
 Treat top level of in-racks as the “floor” for the purposes of
designing the ceiling system
 Do not need to balance in-rack sprinklers with ceiling, nor
account for them flowing simultaneously
 150 mm clearance needed from top of storage to sprinkler
deflector

New 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 impact
