SAFETY CONSIDERATIONS
SAFETY PRECAUTIONS
Personnel properly qualified in the application and use of life safety equipment (“qualified personnel”) shall
read this manual carefully before performing any actions to specify, apply, install, maintain and perform op-
erational tests of IED systems, and associated products in accordance with the instructions in this manual.
This manual shall be made available to all qualified personnel who operate, test, maintain, or service IED
systems, and associated products. It is strongly recommend that such personnel read and understand the
entire manual.
WARNING: IF SAFETY PRECAUTIONS, INSTALLATION AND TESTING ARE NOT PERFORMED PROP-
ERLY, CONDITIONS COULD EXIST IN WHICH THE IED SYSTEM MAY NOT OPERATE, OR MAY OPER-
ATE IMPROPERLY. THIS COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH
TO YOU AND/OR OTHERS.
It is very important that only responsible, trained personnel are allowed to operate and maintain these sys-
tems, and that they use only appropriate equipment and tools. If a person is not trained, they shall contact
the IED factory for direction on how to operate and maintain an IED system.
Unauthorized personnel and equipment must be restricted from the areas of operation.
All operations should be performed carefully, methodically, and without hurrying. Greater effectiveness will
be developed by increased familiarity of personnel with their assignments. During any maintenance opera-
tion, if a malfunction occurs or an incorrect indication appears, stop the operation and determine whether
or not it is safe to proceed. Before performing any step in a procedure, be sure that the preceding step has
been properly executed and correct results obtained. Cleanliness and good housekeeping in all installation
areas are major factors in effective accident prevention. Tools and equipment should be maintained in good
working order and should always be returned to their proper storage place after usage. Cleaning agents
and other cleaning aids should be removed from the equipment areas immediately upon completing the
task at hand.
GENERAL PRECAUTIONS
Changes, modifications, or additions in connection with the IED system equipment shall not be made with-
out explicit authorization of IED.
Safety devices found on mechanical, and electrical and electronic equipment are put there for the protec-
tion of personnel and equipment. These devices must be maintained in good working order and operative
at all times. Safety devices shall never be removed or bypassed unless specifically authorized by the IED
factory. Where safety devices have been rendered inoperable by proper and specific authorization, ad-
equate notices shall be posted to warn personnel of the potential hazard.
Avoid the use of flammable or toxic cleaning fluids, and the use of carbon tetrachloride is prohibited.
Maintenance of the equipment shall be at least what is specified in the IED manuals and literature, and
performed only by qualified personnel.
Whenever operation and maintenance is ongoing, personnel in the equipment areas shall have effective
communications among these areas in order to protect people if any accident occurs.
02-13 PRECAUTIONS
Precautions which are applicable to general electrical or electronic maintenance are as follows:
a. Check yourself. Wear no article that might catch on equipment or that might act as a conductor.
b. Check the working area. The equipment area shall be clean and dry. If possible, stand on a special
insulator such as a rubber mat. There should be ample working space and good lighting.
c. Check the tools. Always use proper tools and check them for their safe condition. Use screwdrivers
with plastic handles. Check test equipment periodically and examine test leads carefully as the slight-
est break in insulation is dangerous.
