This can occur at concentrations ranging between 12% and 19% by volume. SECTION V -- HEALTH HAZARD DATA Acute-Toxicity Values^Oral LD5Q (rat): 2136 mg/kg Inhalation LCLg (guinea pig): 5000 ppm/2 hours Inhalation TCLq* (human): 500 ppm/8 hours Threshold Limit Value: Current OSHA permissible exposure limits (29 CFR 1910.1660) are 500 ppm (8-hour TWA); 500- 1000 ppm periodic excursions are allowed providing 8-hour TWA is at or below 500 ppm; 1000- 2000 ppm excursions allowed only for maximum of five minutes in any two-hour period, 2000 ppm maximum allowable concentration (must not be exceeded). (21 Effects of Overexposure'1 ' Acute: Inhalation effect is primarily narcosis. Principal symptoms may be dizziness, nausea, tingling or numbness of the extremities, sense of fullness in the head, sense of warmth, stupor or dullness, lethargy and drunkenness. Exposure to very high concentrations may lead to unconsciousness or even death in confined or poorly ventilated areas. Eye contact can result in Irritation, pain and discomfort. Prolonged or repeated contact with the skin can cause Irritation and dermatitis. Research^ has recently shown that methylene chloride is . metabolized by the body to carbon monoxide. Further, the amount of carbon monoxide formed is directly related to the amount of methylene chloride absorbed and can be sufficient to produce a substantial stress on the cardiovascular system through the elevation of the level of carboxyhemoglobin (COHb) - the product formed by the combination of carbon monoxide and the blood's hemoglobin thus effectively reducing the amount of hemoglobin available for the transport of oxygen throughout the body. * Lowest Published Toxic Concentration SL 074530 2- - Employees working with methylene chloride should be aware of this hazard. This toxic effect is "additivie" in nature with the risk being greater for smokers, who generally have higher levels of carboxyhemoglobin. Further, employees with a history or even a suspicion of having cardiovascular disease should not be exposed to methylene chloride for any length of time. Methylene chloride is mildly irritating to the skin on prolonged or repeated contact. The problem may be accentuated by liquid becoming trapped against the skin by contaminated clothing and shoes. Eye contact can be painful and irritating but is not likely to cause serious injury. Skin absorption is possible. Chronic: Animal studies showed only light to moderate narcosis, and some deaths apparently due to pulmonary congestion. Other animal studies(3) ranging from 50 to 75 days' exposure at con centrations ranging from 1,300 to 7,200 ppm showed kidney and liver changes. Neither currently available scientific literature nor human experience with methylene chloride indicate any adverse human effects attributable to chronic exposure. Emergency and First Aid Procedures Inhalation Overexposure: Remove to fresh air. If not breathing, give artificial respiration, preferably mouth-to-mouth. If breathing is difficult, give oxygen. Call a physician. Note to Physician: Avoid use of adrenalin in any case where a person has been overcome by methylene chloride. Eye Contact: Flush with plenty of water for at least fifteen minutes! Ff irritation occurs, consult a physician. Skin Contact: Wash thoroughly with plenty of soap and water. If irritation occurs, consult a physician. Swallowing: If conscious, drink a quart of water then induce vomiting by placing a finger far back in the throat. Call a physician. If vomiting cannot be induced, take immediately to a hospital or physician. If unconscious, or in convulsions, take immediately to a hospital or physician. 00 NOT induce vomiting or give anything by mouth. SECTION VIII -- SPECIAL PROTECTION INFORMATION Respiratory Protection -- NIOSH/MESA approved organic vapor respirator for concentrations below 1,000 ppm. For 1,000 ppm and above, use airsupplied respiratory protection. Consult 29 CFR 1910.134 for specific requirements. SL 074531 -3- 5ECTIQN IX -- SPECIAL PRECAUTIONS Precautions to be Taken in Handling and Storing Do not use in poorly ventilated or confined spaces. -- Keep containers tightly closed when not in use. Do not store in unlabeled or mislabeled containers. -- Do not store degreaser clean-out sludge in tightly sealed containers. Other Precautions -- Avoid prolonged or repeated breathing of vapor. -- Use only with ventilation sufficient to limit employee exposure below OSHA permissible exposure limits. -- Avoid contact with eyes. -- Avoid prolonged or repeated contact with skin. -- Do not take internally.
