Warning

High temperature mental components

1. Serious or permanent burns may occur to to exposed skin, and the injury degree varies

with temperature and touch time .

2. To avoid touch or to wear protect gloves.

Warning

Maintain or Install Fire Pump Equipment

1. If proper procedures are not followed during the maintenance or installation of diesel

engine pump group, may result in death or serious injury, or/and equipment damage.

2. When operation, personal protect equipment, such as safety goggles, protect gloves,

helmets, steel toe boots and protect clothing shall be wear.

Warning

injury, and fire pump equipment damage.

－4－

Warning

Accidental or Remote Starting

1. During operation, accidental or remote start the diesel engine/electric motor fire pump

group will result in death or serious injury.

2. Disconnect the starting battery cable with an insulating wrench (first disconnect the

negative pole [－]) and isolate all auxiliary power sources to avoid accidental starting or

remote starting of the fire pump equipment.

should be trained in professional skills and have the operation qualification.

2. When operation, personal protect equipment, such as safety goggles, protect gloves,

helmets, steel toe boots and protect clothing shall be wear.

Warning

High Water Pressure

There is a high water pressure in the fire pipeline, and the pipeline must first release the

pressure in the pipeline during maintenance operation to avoid high pressure damage.

Caution

Risk of Fire

1. Loose cleaning materials can become entangled in moving parts, which can cause

equipment damage or cause a fire.

2. Be sure to clear away all the clean material from the fire pump group, prior to

operation.

－5－

Caution

Risk of Fire

1. The accumulation of combustible materials under the fire pump group may cause fire

accident.

2. Ensure that the fire pump group is fixed in a way that combustible material cannot

accumulate under the equipment.

Caution

Risk of Fire

1. Accumulation of grease and oil may cause overheating and damage to fire pump

group, which will result in fire.

2. Keep fire pump group clean and timely repair fuel leakage.

Caution

Risk of Fire

1. Substances on or near the fire pump group may obstruct and restrict air flow, resulting

in excessive temperature or fire.

2. Keep the fire pump group and the surrounding area clean and barrier-free.

3. Remove debris from fire pump group and keep the floor clean and dry.

Note

Repair Safety

When performing maintenance and repair procedures on a closed fire pump group, ensure

that the access door is opened safely.

fire pump from its AC power supply, and then disconnect the starting battery using the

insulation wrench. First disconnect the negative (-) cable.This will prevent accidental

starting.

3. Disconnect the power supply which turn the switch to OFF of the fire pump in the control

room; and lock the power switch, not allowed to open or close; and all auxiliary power

supply is isolated to avoid accidental starting or remote starting of the fire pump group.

4. Ensure the fasteners on the fire pump group are firmly fixed and tighten the support and

fixture.Ensure that the pipe joints are well sealed without leakage;Keep the fan, drive belt

and other protective cover in place, fuel tank, pressure tank, air conditioning, control

cabinet firmly and reliably installed.

5. Do not wear loose clothing or jewelry when near moving parts or when operating

electrical equipment.Loose clothing and jewelry can get stuck in moving parts.

6. If adjustments must be made during equipment operation, be especially careful with

high-temperature manifolds, moving parts, etc.

1.4.2 Electric Shocks and Arc Flashes may cause serious injury

Warning

Electric Circuit

1. Exposed energized circuits may be at potential ≧400V ac or ≧30 V dc, and any

work in contact with them carries a significant risk of electric shock and arc flicker.

2. These silent hazards can lead to serious human injury.
