Absence of ignition sources
-
No person performing work related to a refrigeration system involving the exposure
of pipes that contain or have contained flammable refrigerants shall use ignition
sources in a manner that may lead to a risk of fire or explosion. All possible sources
of ignition, including a person smoking a cigarette, should be located far enough
from the installation, repair, removal and disposal site during the period when the
flammable refrigerant can flow into the surrounding space. Before carrying out the
work, the area surrounding the equipment must be examined to ensure that there is
no risk of ignition or risk of ignition. "No smoking" signs should be displayed.
- Ventilated areas
Make sure that the area is outdoors or adequately ventilated before working on the
system or performing any work that causes heat. A ventilation of a given degree must
continue during the work. Ventilation should safely disperse any refrigerant emitted
and preferably expel it to the outside into the atmosphere.
- Audits of refrigeration equipment
When electrical components are changed, they must be adapted to their intended
use and to the correct specification. The manufacturer's maintenance and service
guidelines must be followed at all times. In case of doubt, consult the manufacturer's
technical support service.
The following checks shall be applied to installations using flammable refrigerants :
- The size of the charge is in accordance with the size of the room in which the
elements containing a refrigerant are installed ;
- the machinery and ventilation valves are working properly and are not
obstructed;
- if an indirect refrigeration circuit is used, the secondary circuit must be
checked for the presence of refrigerant;
- the marking of the equipment continues to be visible and legible. Marks and
symbols that are illegible must be corrected;
- the refrigeration pipe or components are installed in a position where they
are not likely to be exposed to a substance that may corrode elements
containing refrigerants, unless these elements are constructed with materials
that are inherently resistant to corrosion or that are adequately protected
against corrosion
- Verifications of electrical devices
Repair and maintenance operations on electrical components must include initial
