WARNING
The protective mask or other respiratory protective device and rubber gloves are the
minimum protection equipment for handling HTH.
CAUTION
HTH has a toxic vapor, will burn the skin, and destroy clothing. If HTH comes into
contact with the skin or clothing, flush with large amounts of water.
THE INTERACTION OF DS2 AND HTH MAY PRODUCE HEAT AND FLAME.
THESE ITEMS MUST BE STORED SEPARATELY AND MUST NOT BE MIXED
DURING USE.
2.
Washing Soda (Soda Ash, Laundry Soda, Sal Soda, and Sodium Carbonate).
Washing Soda neutralizes most chemical agents and is especially effective against nerve agents. It is
used as a washing agent for blister agents. A solution is made by stirring 2 lbs. of Washing Soda into 2
1/2 gallons of water. It is applied to contaminated surfaces using the PDDA, swabs, or brooms.
CAUTION
Washing Soda is an alkaline material.
DO NOT use it for personnel decontamination.
3.
Caustic Soda (Lye, Sodium Hydroxide).
WARNING
DO NOT use Caustic Soda or Caustic Potash for personnel decontamination. Both solid
and solution will damage the skin, eyes, and clothing.
Caustic Soda neutralizes chemical and biological agents. It is especially effective against nerve agents.
A 5% solution is made by stirring 1 lb. of lye into 2 1/2 gallons of water. Caustic Soda can be used
instead of the standard decontaminants. It can also be used instead of Washing Soda.
CAUTION
Heat will result from mixing Caustic Soda or Caustic Potash with water. Careful addition
of small amounts at a time will avoid excessive heat. Caustic Soda and Caustic Potash
corrode surfaces, especially aluminum. Personnel handling caustic solutions must wear
protective masks.
