Any person who is involved with working on or breaking into a refrigerant circuit should
hold a current valid certificate from an industry-accredited assessment authority, which
authorizes their competence to handle refrigerants safely in accordance with an industry,
recognized assessment specification.
Servicing should only be performed as recommended by the equipment manufacturer.
Maintenance and repair requiring the assistance of other skilled personnel should be carried out
under the supervision of the person competent in the use of flammable refrigerants.

SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when servicing a dehumidifier
with R290.
2.2.1 Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are
necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system,
the following precautions should be complied with prior to conducting work on the system.
2.2.2 Work procedure
Work should be undertaken under a controlled procedure to minimize the risk of a flammable
gas or vapor being present while the work is being performed.
2.2.3 General work area
All maintenance staff and others working in the local area should be instructed on the nature of
work being carried out. Work in confined spaces should be avoided. The area around the
workspace should be sectioned off. Ensure that the conditions within the area have been made
safe by control of flammable material.
2.2.4 Checking for presence of refrigerant
The area should be checked with an appropriate refrigerant detector prior to and during work, to
ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak
detection equipment being used is suitable for use with flammable refrigerants, i.e. no sparking,
adequately sealed or intrinsically safe.
