310 =ECTION , HEALTH HAZARD INFORMATION TL AdGIH TLV for methylene chloride lowered from 200 100 m 360 m3} Oee Sect 1I) TWA of 75 ppm. Present OSHA value of 500 will probably; NIOSH has proposed a 10-hr Inhalation of high concentrations ca uses loss of and be l equilibrium and. if� exposure is prolonged excessively, unconsciousness and even death. Prolonged skin con- tact can be irritating; absorbed through the skin. Eye contact is painful and irrita- ting, but it isnot believed likely to produce serious injury, Meth leve chloride aceta_ bolizes to toauce carrion monoxide in the bod it increases an sustains car xy ems_ globin levels in the hood, reducing the oxygen-carrying capacity of the blood, FIRST AID: Eye ant Skin Flush contact area with plenty of running water. If irritation persists contact: med get ical attention. nhalation: Remove to. fresh air; give artificial respiration, if required. Keep quiet and warm. Get medical attention; advise physician not to use adrenalin. In estion: Get prompt#edical attention, (If physician unavailable, give water or mil and induce vomiting.) Advise physician not to use adrenalin. FSECTION VII . . SPILL, LEAK. AND DISPOSAL PROCEDURES For small spills, soak up with an absorbent solid, such as vermiculites avoiding breathin cif vapors and using gloves to avoid contact. Evaporate off solvent in an exhaust hood Wheo r bury with absorbent in a landfill. n large spills occur, evacuate area; notify safety personnel P,rotectilre equipment during clean-up, provide ventilation. Us p. $uch as self-contained breathing apparatus, boots gloves, etc, Contain and recover liquid when possible. Pick up residue with absorbent (as with small spills) of flush to ground (not to sewer} to evaporate. Rec-laim waste solvent by filtration and distillation procedures or dispose of via a li- e Iensed, waste solvent disposal company. I I SECTION VIII . SPECIAL PROTECTION INFORMATION - A Use general ventilation and efficient exhaust ventilation to meet TLV requirements. Air s pplied or self-contained breathing apparatus should be available for emergency use. A� full facepiece is required above 750 ppm, Use neoprene or Vicon gloves for skin protection and safety glasses. Chemical goggles or Lface shield should be used where splashing is possible. An eye wash st'atio*,.should readily available if splashing Is probable. NOTE: NIOSH indicates that carbon monoxide content and CH2Cl2•'Content of workplace air are additive and that both must be monitored where methylene chloride The 10-hr TWA for CO must not exceed about 9 m where ex exposures occur, occurs unless, CH2Cl2 exposure is also controlled to a lowerslevelothanhthenTLVhloride SECTION IX. SPECIAL PRECAUTIONS AND COMMENTS Use caution in hancling this material. Avoid airborne concentration build-up. Atloid ex- posure to high temperature. No smoking where vapors of this material are present. Store in a c'bol. well-ventilated area away from sourxes of heat." caution. Open containers with When methylene chloride vapors are drawn into the combustion chamber of a space heater, severe corrosion damage to the heater can occur. even at levels well below TLV. Those with a history of cardiovascular disease or who are heavy drinkers or smokers shoul avoid exposure to methylene chloride.
