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.
