WARNING
Wear protective clothing and a mask when engaged in decontaminating operations. STB decontaminating
agent and slurry are harmful to the skin, eyes, lungs, and clothing. If STB decontaminating agent or slurry
gets into the eyes, flush them immediately with clear water. If STB decontaminating agent or slurry is
taken internally, drink raw egg white, milk, rice gruel, or milk of magnesia. Do not induce vomiting. Seek
medical assistance immediately. If STB decontaminating agent or slurry contacts the skin, wash off
immediately with clear water.
Do not use antifreeze with STB. Heat releasing reaction occurs.
MAKING STB DECONTAMINATING AGENT SLURRY
General
When preparing slurry, add the M2 antiset (Page 0028 00-1, item 2) to the water first. Mix water with M2 antiset for
3 minutes. Next add the silicone antifoam agent (Page 0028 00-1, item 1). Mix silicone antifoam agent for at least
3 minutes before adding the STB decontaminating agent (Page 0028 00-2, item 8). Prepare the slurry as near to using time as
possible. Never prepare slurry more than 4 hours in advance of use. STB will dissolve more rapidly in hot water.
M2 Antiset
M2
ANTISET
12 1/2 LB
DRUM
The M2 antiset (Page 0028 00-1, item 2) retards setting of the slurry. If M2 antiset is not added, especially in cold weather,
the slurry will set rapidly and will form a hard mortar-like mass that will clog the tank and lines. Add M2 antiset in the
proportion of 1 pound to each 100 pounds of STB agent for small quantities of slurry or one 12-1 /2 pound package of M2
antiset per 1,300 pounds of STB decontaminating agent (225 gallons of water). Remove the hopper tank lid and load the M2
antiset into the tank through the hopper-blender.
