HAZARD IDENTIFICATION BASIC PLANNING
Individuals responsible for planning (or designing) a
CHECKFIRE 210 Detection and Actuation System must hold
current ANSUL Certification from an ANSUL A-101 and/or LVS
training program. In addition to the certification, planners must
research:
• Known fire hazards in equipment to be protected
• Federal and local fire protection codes/standards
For easier planning obtain a general model drawing of the
vehicle/equipment with accurate dimensions.
Identify hazard areas needing protection. Agent nozzles in
existing fire suppression systems may point out hazard areas.
For existing or new fire suppression/detection systems review
and apply the following vital information to determine proper
placement of discharge nozzles and detection devices.
Fire Hazard Locations
A fire hazard is any area where an ignition source (heat, high
temperature or sparks) and fuel (flammable materials) may be
found in close proximity. A solid or liquid combustible or flam
-
mable material can cause fire when in contact with an ignition
(heat) source. Fire hazard areas may also exist in locations
where fire can propagate due to dripping or running flammable
liquids.
Examples of ignition (heat) sources:
• Engines
• Exhaust manifolds and piping
• Turbochargers
• Power source compartments
• Electrical system equipment
• Torque converters
• Transmissions
• Hydraulic pumps
• Parking brakes (engaged while moving)
• Bearings, clutches or gears
• Malfunctioning components
• Friction from debris packed around parts
Examples of fuel or flammable materials (may cause rapid
buildup or spreading of fire):
CLASS B MATERIALS
• Leaking fuel (gasoline, diesel, engine oil, hydraulic oil,
glycol, steering fluid, etc.)
• Broken fuel lines/fittings
• Slow leaks – fuel or hydraulic fluid
• Broken hydraulic lines or pumps
• High pressure hoses
• Belly pan (fuel and debris accumulation)
• Ruptured fuel or hydraulic tank
• Greases
CLASS A MATERIALS
• Electric wiring insulation
• Plastic parts
• Rubber
• Debris (wood chips, coal dust, landfill material, etc.)
Identify every foreseeable hazard. Include the occasional
danger of malfunctioning components.
Other Considerations
The propagation of fire from one area to another may cause
a hazard to be larger than originally determined. Liquid fuel
may flow, spray, or splash causing the fire to spread further
than anticipated. Radiation, sparks, or conduction through
metal can carry heat to an area where the danger of fire would
not normally exist. Hand portable fire extinguishers should be
accessible to suppress residual fires or to help with providing
an escape route.
Research the fire history of the equipment or of similar equip
-
ment. This information may be available through company
records or equipment operators who may have first-hand
experience enabling them to identify locations of previous
fires as well as specific hazards such as frequent component
wear, fuel leak points, or ruptures of certain hydraulic fittings or
hoses.
Normal operating temperatures in excess of the detector
ratings will cause the detection system to activate.
Each identified hazard must include both fire suppression
system fixed nozzles and linear detectors or spot thermal
detectors for automatic detection and system activation.
Equipment Shutdown
Plan for the shutdown of components that could add to the
intensity of the fire, re-ignite the fire, or negatively impact the
discharge of fire suppression agent such as:
• Fuel pumps
• Hydraulic pumps
• Engine
• Power source
• Electrical system
• Fans
Automatic pressure bleed-down and/or fuel and hydraulic tank
shutoff valves should also be considered to mitigate fire propa-
gation and/or re-flash.
Electrical interface for automatic equipment shutdown can be
made utilizing either the programmable #2 internal relay in
the ICM or the Pressure Switch Assembly (Part No. 440389)
alone. When the pressure switch alone is used, shutdown will
occur simultaneously with system release. When the pres
-
sure switch is used in conjunction with Detection Circuit #2 as
pressure switch feedback, and pneumatic actuation is utilized,
the programmable #2 internal relay contacts will transfer, and
connected equipment will become energized or de-energized
depending on how the relay is wired.
Consult the vehicle/equipment manufacturer, the manufac
-
turer’s dealer, the site maintenance manager or customer for
details when planning for either shutdown method.
