TCL Air Conditioner Service Manual
25
A maintenance station should establish emergency handling plans. It is necessary to take appropriate
precautionary measures in work. For example, it is prohibited to enter the location with any kindling material
and it is prohibited to wear clothing or shoes which easily produce static.
Handling suggestions when a large amount of combustible refrigerant leaks:
It is necessary to immediately operate the ventilating equipment while cutting off other power supply and
evacuating the affected personnel urgently from the location.
It is necessary to inform near residents of evacuating for over 20 meters from the location, make an
alarm call, set the emergency area and prohibit irrelevant personnel and vehicles from approaching.
The professional firefighters should wear anti-static clothing to handle the emergency on the site and cut
off the source of leak.
It is necessary to use nitrogen for blowing the site, especially the low-lying positions, clear away the
residual combustible refrigerant gas from any area nearby and surrounding the leak point and use a
handheld detector for detection and not clear the alarm until the concentration of refrigerant is zero.
