Stay calm - By staying calm, one can influence others and thereby aid the emergency response
Assess the situation - Determine what happened and what the emergency is. What has happened,
to whom and what will continue to happen.

Take command –The appointed person or ERT will take charge and provide command according
to the emergency situation.
Provide protection - To eliminate further loose and safeguard the area, control energy source,
protect victim, divert traffic, fire suppression, shut down equipment’s, and take other necessary
measures.
Aid and manage - Provide first aid and help those already doing so.
Maintain contacts - Keep emergency response team informed of the situation.
Guide emergency service - Lead emergency team to the location, explain current situation etc.
c. Electric shock
A person being shocked needs to be disconnected from the source of electrical power.
Locate the disconnecting switch/breaker and turn it off. Alternatively, if the disconnecting device
cannot be located, the victim can be pried or pulled from the circuit by an insulated object such as
a dry wood board, piece of non-metallic conduit, or rubber electrical cord.
Victims need immediate medical response: check for breathing and pulse, then apply CPR as
necessary to maintain oxygenation.
If a victim is still conscious after having been shocked, they need to be closely monitored and
cared for until trained emergency response personnel arrive.
There is danger of physiological shock, so keep the victim warm and comfortable. Shock victims
may suffer heart trouble up to several hours after being shocked. The danger of electric shock
does not end after the immediate medical attention.
In addition to that, as per the approved Emergency response plan the emergency procedures shall be
considered. For example
In all cases requiring emergency medical treatment, immediately call, or have a co-worker call, to request
emergency medical assistance to the contact below:

magnitude of spill condition will be considered and the hazards reviewed and classified in accordance with
the relevant rating On-Hazardous materials: All non-hazardous materials spills should, where possible, be
stopped and controlled. Containment and clean up should begin immediately. Hazardous materials: In the
event of a major hazardous material spill all Project personnel will be evacuated from the immediate area to
one of the designated muster points. The Emergency Response Team to secure area by barricades and
responded the spill as per the hazardous material MSDS and COSHH
Eye injury:

The pre-commissioning procedure for the Chilled Water Pumps involves a thorough inspection of the
system installation prior to total enclosure will be carried out to ensure each system is statically
complete and safe to run, the findings will be recorded on the check sheets and if found satisfactory the
start-up will commence.
Verify the installation thoroughly (prior to start up):
a. Check the installation of the pump(s) in the pit. Pump’s pedestal should be grouted and/or
anchored to pit’s floor with the needed guide rails and chain (where applicable).
b. If the pump has no pedestal, it should be resting on its feet and leveled on the pit’s floor.
c. The discharge pipe(s) should not impose any stress on the pump(s).
d. The pit should be free of any solids bigger than the pump’s free passage and/or anything which
can block the pump (e.g. nylon bags, construction material, etc.).
e. Check discharge piping and valve/ accessory installation, accessories recommended
installation to be out of the pit for easy routine checkup and/or repair.
f. Check the wiring of the pumps and the level sensors, connections should be out of pit and at
least 30 cm above pit’s opening, to avoid any damage in case of high level. If this is not
doable, connections can be made inside pit; however the “IP” level should be not less than
IP65.
g. Check the sensors levels, taking into consideration that the pump’s motor should be
submerged in water at least 50% in all cases.

bearing’s temperature sensor, etc.) and connect it to its designated terminals in the control
panel (where applicable).
g. Check that the level sensors are connected to their designated terminals in the control panel.
h. Pit should be full of water (e.g. maximum capacity of the pit).
i. Start each pump manually to check rotation.
j. Start each pump and check its consumed current (must be equal or less than the nominal
current). Reading should be done with the whole length of the discharge pipe(s) is full of water

duplex level, triplex level, and high level).
m. Check all of the indication lamps
n. Check the audible alarms if available
o. Put the pump(s) in “AUTOMATIC” mode; however, the “AUTOMATIC” mode should respect
