When halocarbon vapors come into contact with open flame
or hot surfaces over approximately 572°F (300°C) they de-
compose to produce poisonous chemicals. These chemicals
have a very strong odor warning us of their presence.
Oil mist in the ammonia vapor increases this risk significantly
as the point of ignition falls below that of the mixture ratio
stated.
Usually the strong smell of ammonia will give ample warning
of its presence before concentrations become dangerous.
Check official limits in the location
of your installation. They may differ
from those stated.
VENTILATING A REFRIGERATION PLANT
If it is necessary to ventilate a refrigeration plant, make sure
you observe the following:
• Never release refrigerants directly into the atmosphere.
• When ventilating an R-717 plant, you must use an ap-
proved air ventilator. Released air must pass through
an open water container in which the remnants of R-717
refrigerant will be absorbed. Send the water containing
R-717 to an authorized incineration plant.
COOLING AGENTS
Standard PowerPac
units are designed to use glycol or
™
water as the cooling agent. Other cooling agents include:
Salt solutions (brines) of calcium chloride (CaCl
chloride (NaCl).
In general, all brines must be considered harmful to nature.
Use caution when charging or purging a refrigeration plant.
Never empty brines down a sewer or into the environment.
The brine must be collected in suitable containers, clearly
marked with the contents, and sent to an approved incin-
eration plant.
To lubricate screw compressors included in the PowerPac
units, use only Semisynthetic hydrotreated oil.
When changing the oil in the compressors and when empty-
ing the vessels, the used oil must be charged into containers
marked "waste oil" and sent to an approved incineration
plant.
NOTE: The owner of the refrigeration plant is responsible
for ensuring compliance with all Federal, state, and local
regulations. PSM procedures should be routinely followed.
