Section IV - Fire and Explosion Data Flashpoint of Mixture: 75.5 °C (168 °F) (Closed Cup Method) The lowest flashing component of the mixture, ethylene glycol monoethyl ether has a flashpoint of 46 °C (115 °F) (Closed Cup Method). Flammability Limits (% By Volume): Not Available Lower Explosive Limit: Not Available Upper Explosive Limit: Not Available Extinguishing Media: Water mist, fog, and foam, alcohol foam, CO2. Avoid using extinguishing methods that will cause splashing or spreading of the DS2. Special Fire Fighting Procedures: All persons not engaged in extinguishing the fire should be immediately evacuated from the area. Fires involving DS2 should be contained to prevent contamination to uncontrolled areas. Unusual Fire and Explosion Hazards: Never mix or store acids, oxidizing agents, Supertropical Bleach (STB), or High Test Hypochlorite (HTH) with DS2; fire or explosion may result. Section V - Health Hazard Data Airborne Exposure Limits (AEL): DS2 is made of two major components (EGME & DETA) with different toxicity's and physical properties. The TLV of the mixture (calculated) is 5.2 mg/m3 as an 8-hour time weighted average (TWA). To date Occupational Safety and Health Administration (OSHA) has not promulgated a permissible exposure limit for DS2 nor has the value proposed been officially adopted as a part of a special occupational safety and health standard for DS2 in accordance with DOD 6055.1. DS2 is not listed by the International Agency for Research on Cancer (IARC), American Conference of Governmental Industrial Hygienists (ACGIH), Occupational Safety and Health Administration (OSHA), or National Toxicology Program (NTP) as a carcinogen. Effects of Overexposure: No toxicity data are available on DS2. However, the toxicity of each of the components has been partially determined. DS2 is an alkali and with direct contact will corrode tissue, e.g., skin, eye, respiratory mucosa or gastric mucosa. The effects exhibited depend on route of exposure, amount of substance present, and duration of exposure. Health effects can range from mild burns and primary irritation to corneal opacification, severe burns, and esophageal stricture. Sufficient exposure to EGME, a major component of DS2, may cause central nervous system depression and liver damage. Although not definitely established in humans, reproductive effects (including teratogenisis) are also a major concern with this substance. The National Institute for Occupational Safety and Health (NIOSH) recommends that EGME be regarded in the workplace as having the potential to cause adverse reproductive effects in male and female workers. Appropriate controls must be instituted to minimize worker exposure to EGME. Exposure to high vapor concentrations of DS2 can cause nausea, vomiting, and respiratory irritation as acute effects. Repeated skin and respiratory exposures to DETA can cause skin sensitization and asthma. Emergency and First Aid Procedures: Inhalation: Remove to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen. Additional supportive measures may be required. Seek medical attention Immediately. Eye Contact: Immediately flush eyes with water for 10-15 minutes. Seek medical attention Immediately. Skin Contact: Immediately wash contaminated skin with copious amounts of soap and water, until "soapy residue" on skin is no longer present. Seek medical attention Immediately. Ingestion: Do not induce vomiting. First symptoms are likely to be gastrointestinal. Immediately administer Nerve Agent Antidote Kit, Mark I. Seek medical attention Immediately. Section VI - Reactivity Data Stability: Avoid extreme temperatures, 160 °F or higher, during storage. Incompatibility:DS2 is a corrosive material and because of its content, it is incompatible with some metals (e.g., cadmium, tin and, zinc); some plastics (e.g., lexan, cellulose acetate, polyvinyl chloride, Mylar, and acrylic); some paints; wool; leather; oxidizing materials (e.g., STB or HTH); and acids. Hazardous Decomposition: DS2 will deteriorate in air. Exposure of 48 hours or more to open air will result in the formation of gelatin-like bodies on the surface of DS2. Hazardous Polymerization: Unknown. Section VII - Spill, Leak, and Disposal Procedures Steps To Be Taken in Case Material is Released or Spilled: If leaks or spills of DS2 occur, only personnel in full protective clothing will remain in the area (See Section VIII ). In case of personnel contamination, see Section V for emergency and first aid instructions. During spills provide adequate ventilation and remove any ignition source. During clean up, personnel should wear a full face respirator with an organic vapor cartridge effective against Diethylenetriamine and Methyl Cellosolve, rubber gloves long enough to protect hands and arms, rubber boots, and a full length rubber apron. Contaminated clothing and boots/shoes should be removed immediately and washed thoroughly with water before reuse. Avoid contact with leaking liquid or vapor. All wash water should have pH measured. Any liquid with a pH less than 2.0 or greater than 12.5 is hazardous waste with an EPA number of D002. Spills on porous surfaces (concrete, wood, etc.) should be cleaned and neutralized immediately. Otherwise, they will be absorbed and become an andefinite hazard. All spills must be contained, by covering with dry sodium bisulfate to neutralize and then absorbing them on vermiculite clay or diatomaceous earth. Scoop up all this material and any contaminated soil or substrate, and place in an epoxy coated drum with a fully removable head, and label as corrosive IAW EPA and DOT requirements. Leaking containers may also be repacked in a steel removable head drum conforming to a 1A2 container of Title 49 CFR, ICAO, or IMO as applicable. Dispose of material according to Federal, state, and local laws. Other containers can also be used provided they meet the test requirements for 1A2 containers as specified in the 49 CFR 178.504. Waste Disposal Method: Waste DS2 has been tested and is a hazardous waste with an EPA waste number of D002. Disposal methods for waste DS2 and accumulated spill cleanup residues must comply with RCRA, State, and local hazardous waste regulations and procedures. If the wastes are corrosive they have the EPA Hazardous Waste Number of D002. This number should be used when the waste is manifested, to permit the use of off-site hazardous waste disposal facilities. For disposal of excess stocks of pure DS2, coordinate with the Defense Reutilization and Marketing Office (DRMO). Disposal methods at overseas military installations must be in accordance with the laws of the host country. Section VIII - Special Protection Information Concentration Respiratory Protective Equipment As a mixture < 5.2 mg/m3 (i.e., 3.7 mg/m3 & 1.5mg/m3) Escape type respirators will be available when necessary. Any NIOSH approved full-face piece respirator with an organic vapor canister. (i.e., M40-series mask) >5.2 mg/m3 or unknown concentration Any NIOSH approved full-face piece pressure demand SCBA. Any NIOSH approved full-face piece positive pressure, supplied-air respirator with auxiliary SCBA.Note: For military personnel engaged in training scenarios the M40-series mask is acceptable. Filter elements and canisters should be changed after each use with DS2. Ventilation: Local exhaust: Mandatory if TLV (TWA) is exceeded. Protective Gloves: Butyl Rubber Glove M3 and M4 Norton, Chemical Protective Glove Set Eye Protection: At a minimum splash proof chemical goggles will be worn. For splash hazards use goggles and face shield. Other Protective Equipment: For laboratory operations, wear lab coats and gloves and have mask readily accessible. In addition, clean smocks, foot covers, and head covers will be required daily when handling contaminated lab animals. Section IX - Special Precautions Precautions To Be Taken In Handling and Storing: No smoking, eating, or drinking in areas containing DS2 is permitted. Containers should be periodically inspected for leaks. Stringent control over all personnel practices must be exercised. Safety showers, eyewash stations, and personal cleanliness facilities should be readily available. Wash hands before meals and shower thoroughly with special attention given to hair, face, neck, and hands, using plenty of soap and water before leaving at the end of the workday. Other Precautions: Avoid extreme temperatures during storage (e.g. 160 °F or higher). Section X - Transportation Data Proper Shipping Name: Caustic Alkali Liquids, n.o.s.
