MIXING CHEMICALS OTHER THAN STB IN TANK - Continued
Sodium Carbonate
NOTE
Sodium carbonate is commonly called soda ash, sal soda, washing soda, or laundry soda. The commercial
grades may contain large amounts of sodium bicarbonate (baking soda). A sodium carbonate mixture does
not neutralize blister agents or V-agents as readily as caustic soda or calcium hypochlorite. A hot or cold
soda ash solution is effective on G-agents. Sodium carbonate is not as toxic as other decontaminants.
However, crew members handling and preparing the solution should wear protective masks and gloves to
guard against heavy clouds of powder.
Sodium carbonate (Page 0028 00-3, item 23) is available in 100 pound bags.
1. Fill the tank unit with 400 gallons of water. See Page 0007 00-12 for hose, fuel, and electrical connections for heating
water in tank. Heat the water to an indicated temperature of 75F. After heating the water, place THERMOSTAT to OFF.
Continue circulating water for 2 minutes through the heater, then turn HEATER ON/OFF switch to OFF.
