( MATERIAL SAFETY DATA SHEET V N0, 310 CORPORATE RESEARCH & DEVELOPMENT aS�'b METHYLENE CHLORIDE SCHENECTADY, N. Y. 123059) - SION C Phone: (518) 385--4085 DIAL Wife 8*235-4085 NFORMAR)C Date September 1978 SECTION I . MATERIAL. IDENTIFICATION TERL4I NAME: METHYLENE CHLORIDE OTHER DESIGNATIONS: Dichloromethane, Methane Dichloride, CH2C12,GE Haterial D5389, ASTM 03506, CAST 000 075 092 MANUFACTURER: Avallable from many suppliers, including Dow Chemical Co. and Diamond Shamrock Corp.. Electrochemical f SECTION If . 1NGROEDIENTS AND HAZARDS X HAZARD DATA Methylene Chloride Ca 100 8--hr TWA 100 ppm* *ACGIH (197$) Intended changes list has dropped TLV from pp Human, inhalation 200 ppm to 160 ppm. Current OSTIA TLV remains at 500 ppm. TCLo 500 ppm/8-hr NIOSH has proposed a 75 ppm 10 hr-TWA with a ceiling con- m. (blood effects) centration of 500 PP (15 minute sampling period) 17IOSH also warns that toxic hazards with CK2C12 are in- Rat oral LD 50 creased by the presence of alcohol and/or carbon mon- 2196 mg/kg oxide and by heavy labor and smoking.

FIRE AND EXPLOSION DATA LOWER UPPER F ash Point and Method Autoi nition Te Flammabilit Limits In Air None >103.3 F I Vol, I at >100 C 12 his material does not give a flash or fire point by the conventional test methods. It does form weakly combustible mixtures at high temperatures and high concentrations in air; and it can burn or explode in oxygen enriched air. Firefighters should use self-contained breaching apparatus (with eye protection) for pro- tection from suffocating and intoxicating vapors and from high temperature decomposition products. SECTION V. REACTIVITY DATA ethylene chloride is a stable compound under normal conditions of storage and use; how- ever, exposure to high temperatures (open flames, welding arcs, etc.) can give corrosive and toxic thermal-oxidative decomposition products such as hydrogen chloride and phos- gene. It does not undergo hazardous polymerization. rolonged exposure to excess water may cause noticeable hydrolysis above 60 C. revent contact with alkali metals and finely powdered aluminum and magnesium to avoid Possible violent reactions.
