available in two sizes and can be worn on either foot. They are issued in a polyethylene bag with two pairs of laces and an instruction sheet. The undamaged overboots provide protection to the feet against chemical agents. Upon con- tamination, the overboots provide 6 hours of pro- tection from agent penetration. Donning  procedures  are  listed  with  the chemical-protective  overgarment. Chemical-Protective Glove Set The chemical-protective glove set is worn to protect the hands against nerve and blister agents, liquids, and vapors. The set consists of an outer glove to provide chemical protection and an inner glove to assist in absorption of perspiration. The 5-finger outer glove is made of impermeable, unsupported, black butyl rubber and is manufac- tured for both the right- and left-hand. The thin, white cotton inner glove can be worn on either hand.  The  glove  set  is  issued  in  a  clear polyethylene bag with an instruction sheet. The  black  outer  glove  protects  against chemical  agent  vapors,  aerosols,  and  small droplets. Upon contamination, the set provides at least 6 hours of protection from agent penetration. These gloves, in good condition, can be decontaminated and reissued, Wet-Weather Clothing Wet-weather clothing is often described as impermeable or rubberized clothing. Its value results from the fact that the previously described impregnated/protective clothing can be partially penetrated by all but the smallest droplets of liquid agents, especially in relatively high winds. Moreover, the impregnated/protective clothing is not equally efficient in neutralizing all liquid CW agents. Wet-weather clothing, on the other hand, is for a limited time resistant to all liquid CW agents, provided that the closures at the neck, wrists, and protective mask are well adjusted or taped. Wet-weather clothing provides a measure of protection against CBR contaminants when worn over ordinary clothing; but as was previously stated, it provides the most complete protection when  worn  over  impregnated  or  protective clothing. Gradual penetration of the synthetic rubber layer of the wet-weather clothing will eventually occur unless CW agent contaminants are promptly removed. The contaminants are removed by frequent and thorough flushing of the surface with a seawater washdown or an equivalent, such as jury-rigged topside seawater showers, or by swabbing with liquid hypochlorite. In warm weather or during periods of increased physical activity, wet-weather clothing has a major disadvantage in that it can only be tolerated for relatively  short  periods  of  time.  Tolerance  is limited because no air can pass through the clothing to cool the wearer’s body by the evapora- tion of perspiration. Perspiration is normally accumulated inside an  impermeable  suit.    Underclothing, gloves, socks, and shoes may become saturated. Sweating can be reduced and tolerance times lengthened by reducing the exercise rate, by using water-spray cooling, and by reducing exposure to direct sunlight. Ordinary Work Clothing Special protective clothing is not required for all personnel. Ordinarily, it is worn only by the personnel  of  monitoring  and  decontamination teams who must work in or near hazardous areas. All other personnel working near these areas should  wear  two  layers  of  ordinary  clothing, which provide partial protection against agents and radioactive particles. M258A1 SKIN DECONTAMINATING  KIT The M258A1 kit will decontaminate skin and selected personal equipment that has been con- taminated with chemical agents. The kit is housed in a plastic waterproof case with a metal strap hook for easy attachment to clothing or equip- ment such as the mask carrier. The kit consists of three Decon 1 towelette wipes and three Decon 2 towelette wipes that are sealed in tear-away, impermeable foil packets. The Decon 1 packet has a tab for immediate identification at night. The Decon 1 packet contains  a  pad  prewetted  with  hydroxyethyl phenol, sodium hydroxide, ammonia, and water. The Decon 2 packet consists of a pad impregnated with chloramine-B and sealed glass ampules filled with a solution of hydroxyethyl, zinc chloride, and deionized water. The glass ampules are enclosed in a mesh bag to prevent injury to fingers or hands when crushing the ampules. The M258A1 kit is used to remove and decontaminate blister and nerve agents from the exposed skin. It can be used to decontaminate the face (except eyes and mouth), mask interior, rubber gloves, or rubber 6-20
