CHM.......Fire Barrier Kits
for Oil Storage Tanks
|
|
| Is
a barrier needed? The
legal requirement for fire protection of fuel oil storage
vessels means that a fire barrier must be used to protect
the tank from any potential source of ignition in the surrounding
area.
|
A 30 minute
fire rated barrier is required where oil storage tanks of
less than 3,500 litres capacity serving single family dwellings
are sited:-
- Within 760mm of a combustible
boundary
- Within 1800mm of a combustible wall of a building
- Within 1800mm of an opening in a non combustible wall
(door, window, flue, etc.)
A 60 minute fire rated barrier
is required for commercial installations and tanks of over
3,500 litres capacity. Further information on 60 minute
installations can be found in OFTEC information sheet TI/136.

| Why use
CHM Firewall Barriers?
The test used to rate fire barriers for
oil tanks measure both integrity of the barrier in a fire
situation and the insulation it provides. The insulation
requirement is very difficult to achieve. Many materials
which have excellent integrity in a fire situation do not
provide the insulation required.
After 30 minutes in the standard fire test
the exposed side of the fire barrier reaches over 900°C
. To achieve a 30 minute fire rating, the temperature on
the non-fire side must be less than 140°C above ambient
temperature.
A solid steel plate may meet the 30 minute
fire resistance criteria for integrity but would fail in
less than 5 minutes on insulation. Fire rated mineral boards
also have high fire integrity but are likely to fail on
insulation in less than 30 minutes unless a high thickness
material is used.
CHM Firewall Barriers
are designed to meet OFTEC requirements. Barriers are available
with 30, 60 or 120 minute fire ratings. For domestic applications,
barriers are supplied in easy to assemble, made to measure
kits. For commercial and industrial installations bespoke
systems can be supplied, tailored to suit the specific requirements
of the site.

CHM
Firewall Barrier Kits
CHM Firewall
Barriers are delivered in easy to assemble kit form. Each
barrier kit contains sufficient panels to make up the
total dimensions of the barrier. The panels are assembled
together using u-section and h-section channel. Standard
timber fence posts can be used to support the barrier.
These must be positioned on the tank side of the barrier
so that they are protected from any fire. Kits include
all screws and fixings to fit to a wooden fence post.
Kits contain everything required except fence posts.
