Standard operating procedure examples
Standard Operating procedure is a document in
which all standard process to operate or to execute any process written in a
format or in Defined style.
There are many formats available which different
Industries adopt as per their requirements. A common Standard Operating
procedure example is as per following Detail.
A Standard Operating Procedure generally have

So Let’s take an example for Standard Operating
Procedure of Air Handling Unit
Purpose
To describe the procedure for operation of
AHU.
Scope
This standard operating procedure is
applicable for operation of AHU installed in (Write Company Name Here).
Responsibility
Operator/Designee of Engineering Department Follow
operating procedure
Executive/Designee of Engineering Department To
check log book and operation
Implementation of the procedure
HOD Engineering To Ensure the timely maintaining log book & implementation
of SOP
HOD QA Responsible for Implementation and
Compliance of the SOP
Procedure:
Pre Requisite:
Check the cleanliness of AHU it should be
clean.
Check Power supply.
Ensure that there should not be any leakage in
AHU Doors/Frame.
Ensure that supply air damper, return air
damper, fresh air damper and bleed air
damper is in open position on the marked
position, Frequency for damper position verification to is weekly and should be
verified by QA Personnel record damper position
Ensure that hot water generator is working.
Check & ensure that silicon tube of
Differential pressure switch is mounted across filters to monitor differential
pressure should be properly fitted at their places.
Starting Procedure:
Switch ON the main supply from the main HVAC
panel a red indicator will glow up.
Switch ON MCB’s mounted inside the AHU control
panel RYB indication glow on AHU control panel.
Switch ON the AHU blowers by turning selector
switch to on position from control Panel.
To Switch ON outdoor unit set selector switch
to Auto mode.
Set the required temperature & RH on
Temperature & RH Controller.
Observe for any abnormality in running of AHU,
if found rectify it.
Check the pressure of Hot water. It should be
NLT 1.5 kg/cm2.
Differential pressure across the filter shall
be as follow:
Differential pressure across pre filter shall
be NMT 160Pa. In case of increase of DP,
Indication will glow on the panel for cleaning
of filter, take the filter for cleaning.
Differential pressure across fine filter shall
be NMT 180Pa. In case of increase of
DP, Indication will glow on the panel for
cleaning of filter, take the filter for cleaning.
Frequency of monitoring of Temperature &
RH & Differential Pressure is twice in a day
Shut down Procedure:
Switch OFF the AHU blower by turning selector
switch to off position from control
panel Also switch off outdoor unit set
selector switch to zero mode.
Switch off MCB’s mounted inside the AHU
control panel.
Switch OFF the main supply of the operating
panel of AHU by turning selector
switch to off position.
