REFRIGERANT SAFETY
ASHRAE Standards 15-2010 and 34-2010 offer guidelines that address refrigerant safety and the maximum allowable concentration of
refrigerant in an occupied space. Refrigerant will dissipate into the atmosphere, but a certain volume of air is required for this to occur safely.
For R410A refrigerant, the maximum allowable concentration of refrigerant is twenty-six (26) lbs. per 1,000 cubic feet of an occupied space.
Buildings with twenty-four (24) hour occupancy allow half of that concentration.
ASHRAE Standards 15 and 34 assume that if a system develops a leak, its entire refrigerant charge will dump into the area where the leak
occurs. To meet ASHRAE Standards 15 and 34, calculate the refrigerant concentration that may occur in the smallest room volume on the
system, and compare the results to the maximum allowable concentration number. Also consult state and local codes in regards to
refrigerant safety.
Verify the maximum refrigerant concentration level for spaces served by DOAS meets the concentration limit for the application.
