Furthermore, before opening the refrigeration system or working on it:
•
continuously check if the ambient atmosphere is non- explosive and ensure proper ventilation of the room;
•
if the atmosphere is explosive or reaches a dangerous concentration of flammable gas, avoid any ignition
source and ventilate the room further;
•
if parts of the refrigeration system are charged with flammable refrigerant, be sure that all the valves are
tightly closed and that the open pipes after the valves are free of refrigerant and oil.
