2.2 - CHECKS TO PERFORM BEFORE INSTALLATION
a. Checks at the area
Before starting to work on the systems containing inflammable refrigerants, safety
checks are necessary to reduce the risk of ignition to a minimum.
To repair a refrigeration system, the following precautions must be complied with
before working on the system.
b. Work procedure
The job must be performed according to a controlled procedure in a way to reduce
the risk of the presence of inflammable gas or vapour to a minimum during the
performance of the job.
c. General work area
All maintenance personnel and those working in the local area, must be trained
regarding the job performed.
Do not work in tight spaces.
The area around the work area must be isolated.
Guarantee that the conditions inside the area are safe by verifying the inflammable
material.
d. Check the presence of refrigerant
The area must be controlled with a specific refrigerant detector before and during
the performance of the job, in a way to guarantee that the technician is informed
regarding the presence of potentially inflammable atmospheres.
Check the leak detector equipment used is suitable for use with inflammable refrigerants,
i.e. does not cause sparks, is suitably sealed or intrinsically safe.
e. Presence of extinguishers
Whenever work must be performed on the refrigeration system at high temperatures
or on relative components, a suitable fire-prevention system must be prepared.
Position CO2 or dry powder extinguishers in proximity of the loading area.
