w Only 11seconds into the fire it has reached the top of the second
level – half the time it took in the test earlier on
w After 31 seconds the fire has reached the ceiling – 12m high.
Here we can also see the second ‘target rack’ – if the fire reaches
this rack then the test is deemed to have failed
w After only 34 seconds we have 4 sprinkler operating which
control the fire. Ceiling temperatures were controlled at less than
50 °C after about 2 minutes.
After The Test
Figure 32. After-test photos
In the after-test photos we can clearly see the impact that the
sprinklers in combination with vertical barriers has had on the fire
growth. The fire damage is limited to within the barriers and does
not spread to the outer parts of the rack.
In addition, the fast activation of the sprinklers has meant that even
within the barriers the damage was limited.
Conclusion
As a result of this series of tests we were able to gain the approval
of the third part certification body of Germany, the VdS. This means
the scheme can be utilised by other warehouse operators as long
as they follow the rules in the system datasheet
This protection scheme now allows the customer greater freedom
in how and where they stores the goods in their warehouses. It is
a great example of where the co¬operation of an end-user, system
provider, contractor and approval body can produce a scheme
which all are happy with.
So when considering fires in warehouses we can see that the size
and growth will depend on several factors:
w What you store
w How you store it
w How high you store it
Sprinklers have a proven track record of protecting warehouses
and are accepted as the best way to reduce the damage from fire.
But, as warehouse operators requires greater flexibility in all these
aspects the type of sprinkler protection you choose must match
the risk.
There are many standard ways to sprinkler protect warehouses
and your sprinkler contractor can advise you the best option to
take. However if you have a non-standard problem or wish to try
something outside what the standard allows then that is not the
end of the road, systems and products can be developed to match
your needs.

Chris Gill has a Masters degree in Chemical Engineering with
Environmental Technology and began his career working for the
Loss Prevention Council (LPC) in the UK where he carried out
sprinkler research projects in support of the European Sprinkler
standard and LPC Sprinkler Rules. He later moved to the LPCB
where he took charge of managing the active fire protection
equipment approvals covering sprinkler, gas, fire extinguisher
and hose reel testing and certification. In 2004 Chris joined Viking
and is now their Technical Services and Product Manager where
he is principally involved in helping end users, insurers and fire
authorities find the right fire system solution and ensuring Viking has
a complete product line to offer its customers. Chris is a member
of several International and European committees on water, foam
and powder systems and continues to contribute to many National
and International groups involved in active fire protection.
