5.1. Fire Protection
The design, selection and installation of fire protection
systems require the following considerations:
• The fire protection system must comply with the
requirements of National Standards.
• Typically, the generator room will be required to
have a one hour fire resistance rating. Generator room
construction will have to have a two hour fire resis-
tance rating.
• Generator room shall not be used for storage pur-
poses.
• The authority may specify the quantity, type and siz-
es of approved portable fire extinguishers required for
the generator room.
• A manual emergency stop station outside the gener-
ator room or enclosure or remote from the generator
set in an outside enclosure would facilitate shutting
down the generator set in the event of a fire or anoth-
er type of emergency.
General
• Do not permit any flame, cigarette, pilot light, spark,
arcing equipment, or other ignition source near the
generating set or fuel line.
• Fuel lines must be adequately secured and free of
leaks. Fuel connection at the engine should be made
with an approved flexible line.
• Be sure all fuel supplies have a positive shut-off.
5.2. Exhaust Gases
• Be sure the exhaust system will properly dispel dis-
charged gases a way from enclosed or sheltered areas
and areas where individuals are likely to congregate.
• Never connect the exhaust system of two or more
engines.
• Never discharge engine exhaust into a brick, tile or
cement block chimney, or a similar structure. Exhaust
pulsations could cause severe structural damage.
• Do not use exhaust gases to heat a compartment.
• Be sure that the unit is well ventilated.
• Ensure that there is independent support for the ex-
haust system. No strain should be imposed on the en-
gine exhaust manifolds. Which is especially important
on a turbo-charged engine.
5.3. Moving Parts
• Tighten supports and keep guards in position over
fans drive belts etc. Make sure that fasteners on the
set are secure.
• Keep hands, clothing and jewellery away from mov-
ing parts.
• If adjustment must be made while the unit is running,
use extreme caution around hot manifolds, moving
parts, etc.
5.4. Hazardous Voltages
Improper wring can cause fire or electrocution, result-
ing in severe personal injury or death and property or
equipment damage.
For personal protection, stand on a dry wooden plat-
form or rubber insulating mat, make sure clothing and
shoes are dry, remove jewellery from hands and use
tools with insulated handles.
• Do not leave cables trailing on the engine room floor.
• Do not use the same trunking for electric cables and
water lines.
• Do not run AC and DC cables in the same looms
or trunking
• Always ensure that bonding and equipment earthing
are correctly done. All metallic parts that could be-
come energised under abnormal conditions must be
properly earthed.
• Always disconnect the batteries and battery charger
when serving or carrying out maintenance particular-
ly on equipment arranged for automatic mains failure
operation. Always disconnect a battery charger from
its AC source before disconnecting the battery cable.
Accidental starting of the generator set while working
on it can cause severe personal injury or death.
• Do not tamper with interlocks.
• Do not connect the generator set directly to any
building electrical system.
• Always follow all applicable state and local electrical
codes. Have all electrical installations performed by a
qualified licensed electrician.
High voltage sets work differently to low voltage ones.
Special equipment and training is required to work
around high voltage equipment. Operation and main-
tenance must be done only by persons trained and
qualified to work on such devices. Improper use or
