VISCOSITY (centistokes): 9.9 @ 20 DEG C ---------------------------------------------------------------------------- SECTION IV - FIRE AND EXPLOSION DATA ---------------------------------------------------------------------------- FLASHPOINT: (Method Used): The flashpoint of the mixture has been determined to be 168 DEG F (75.5 DEG C) by the closed cup method. The lowest flashing component of the mixture (ethylene glycol monomethyl ether) has a flashpoint of 115 DEG F (46 DEG C) by the closed cup method. EXTINGUISHING MEDIA: Carbon dioxide, alcohol foam, water UNUSUAL FIRE AND EXPLOSION HAZARDS: Never mix or store acids, oxidizing agents, STB (Supertropical Bleach) or HTH (High Test Hypochlorite) together with DS2; fire or explosion may result. ---------------------------------------------------------------------------- SECTION V - HEALTH HAZARD DATA ---------------------------------------------------------------------------- THRESHOLD LIMIT VALUE: DS2 is made of two major components (EGME & DETA) with different toxicities and physical properties. The TLV of the mixture (calculated) is 5.2 mg/m3 as an 8 hour time weighted average (TWA). To date the Occupational Safety and Health Administration (OSHA) has not promulgated a permissible exposure limit for DS2 per se 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. EFFECTS OF OVEREXPOSURE: No toxicity data are available on DS2 per se; however, the toxicity of each of the components has been partially determined. (1) 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. (2) 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. (3) Exposure to high vapor concentrations of DS2 can cause nausea, vomiting, and respiratory irritation as acute effects. (4) 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 artifical respiration. If breathing is difficult, give oxygen. Seek medical attention immediately. Additional supportive measures may be required. EYE CONTACT: Immediately flush the eyes with copious amounts of water for at least 15 minutes. Seek medical attention immediately. SKIN CONTACT: Flush away the DS2 from the skin with water until "soapi- ness" is no longer present. Seek medical attention immediately. INGESTION: If the patient is conscious, give as much milk or water as possible. Do not induce vomiting. Seek medical attention immediately. Supportive measures may be required. ---------------------------------------------------------------------------- SECTION VI - REACTIVITY DATA ---------------------------------------------------------------------------- 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., Supertropical Bleach or High Test Hypochlorite); and acids. REACTIVITY: 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. --------------------------------------------------------------------------- SECTION VII- SPILL, LEAK AND DISPOSAL PROCEDURES --------------------------------------------------------------------------- STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Spills on porous surfaces (concrete, wood, etc.) should be cleaned and neutralized immediately. Otherwise, they will be absorbed and become an indefinite hazard. All spills must be contained, e.g., by covering with dry sodium bisulfate to neutralize and then absorbing them on vermiculite (NSN 5640-01-324-2664), clay or diatomaceous earth. Scoop up all this material and any contaminated soil or substrate and place in an epoxycoated 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. Drums which are cited in the document include: 7 gal NSN - 8110-00-254-5714 27 gal NSN - 8110-00-082-2625 57 gal NSN - 8110-00-082-2626 Other NSNs can also be used provided they meet the test requirements for 1A2 containers as specified in CFR Title 49. 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, and a full length rubber apron. Contaminated clothing and 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. All material with a pH less than 2.0 or greater than 12.5 is hazardous waste with an EPA numbeany 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, and a full length rubber apron. Contaminated clothing and 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. All material with a pH less than 2.0 or greater than 12.5 is hazardous waste with an EPA number of D002.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----------------------------------------------------------------------------RESPIRATORY PROTECTION:Concentration (mg/m3) Respiratory Protection 8 hour TWA---------------------- -----------------------------------------------Less then 5.2 (as mixture Escape type respirators shall be available wheni.e., 3.7 mg/m3 DETA and necessary. 1.5 mg/m3 EGME) o any NIOSH approved full facepiece respirator with an organic vapor canister.
