K. Ensure that the surrounding area is kept clear of loose debris, rubbish and other inflammable rubbish 
near the compressor. 
L.  During  maintenance  activities open all doors to prevent combustible  vapour / fumes  from 
accumulating. 
M. Do not place the compressor near or under vegetation to prevent contact with hot exhaust gases and 
or exhaust components. 
N. The anti-freeze agent used for some anti-freeze systems contains flammable methyl alcohol. Keep 
ventilated and isolate any open flame when using or adding such type of anti-freeze agent. Such type of 
system or agent cannot be exposed in the environment with the temperature higher than 66

. The 

specific gravity of anti-freeze  agent vapour  is greater than the air. Do not store such type of product 
where insufficient ventilation is available.  Do not directly expose the anti-freeze  agent or container 
under the sunlight. 
O. All flammable liquid shall be stored at a place far away from the working site. Get familiar with the 
extinguisher position, type and using method. Check the conditions of fire extinguishing system. 

2.5 Moving Components 

A.  Hands, arms, other body parts and clothing must  stay clear of the cooling fan and other moving 
components. Enclosure doors and panels must be securely fastened to ensure the safety of operators.   
B. Do not operate the compressor after the protective cover of fan or other components is removed. 
C. Wear appropriate personal protective equipment whilst operating this equipment particularly near hot 
surfaces or moving components. 
D. Close the door on the unit when the maintenance is not carried out. 
E. Ensure no one is in the unit and all doors and panels are closed and in place prior start-up. 
F. The following operations can be made only after shutdown: filling fuel oil, cooling liquid, lubricating 
oil, replacing battery or diethyl ether tank, etc. 
G. Disconnect the battery before carrying out any maintenance, to avoid accidental start-up of engine. 
After disconnection, make a clear identification to prevent reconnection by others. 
H. Keep the ground near the control component and unit clean, and timely clean the oil and water stain 
to prevent slipping or fall-off. 

2.6 Hot Surface and Sharp Angles 

A. Do not contact hot oil, cooling liquid and hot surface. Please note not to touch the sharp angles. 
B. Do not directly face the exhaust port of compressor and diesel engine with any part of your body. 
C.  Wear the protective article such as gloves, working clothes and helmet during operation or 
maintenance. 
D.  First-aid kit shall be provided. The injured should be treated immediately. Do not ignore small 
scratches and burns that may cause infection.
