International Agency for Research on Cancer (IARC): Group 2A - Probably carcinogenic to humans. Following cessation of exposure, methylene chloride concentrations in exhaled air dropped rapidly. Data from two additional studies of the animal carcinogenicity of methylene chloride are available from a 1985 National Toxicology Program (NTP) technical report.14 Groups of Fischer 344/N rats and B6C3F1 mice were exposed to methylene chloride (maximum purity, 99%) by inhalation for 2 years, 6 hours per day, 5 days per week at concentrations of 0, 1000, 2000, or 4000 ppm and 0, 2000, or 4000 ppm, respectively. In addition, OSHA considers methylene chloride a potential occupational carcinogen. The data obtained by the NTP from studies with methylene chloride using rats14 demonstrate exposure and dose-related increases in benign mammary tumors in males and females, respectively, and exposure-related malignant tumors of the lung and liver in male and female mice. Those findings are not conclusive and require additional verification. In four human subjects exposed to methylene chloride (350 mg/cu m) for 2 hr, an average of 22.6 microg methylene chloride was excreted in the urine within 24 hr after the exposure. Note to Physicians: This chemical forms carbon monoxide in the body. OSHA 3144-06R, Methylene Chloride. Methylene chloride, also called dichloromethane, is a volatile, colorless liquid with a chloroform-like odor. Found inside – Page 137Overall , studies of controlled human exposure to methylene chloride do not show ... symptoms when compared to a nonexposed referent group ( Cherry et al . Based on these findings, the NTP stated that ” there was some evidence of carcinogenicity of dichloromethane for male F344/N rats as shown by an increased incidence of neoplasms of the mammary gland. An increased incidence of the mammary gland tumors was also reported for the male rats exposed at 3500 ppm, but the increase was less pronounced than that for the females. Parent, in Encyclopedia of Toxicology (Second Edition), 2005 Human. The actual delivered doses in each study were generally within 10% of the target doses. Methylene Chloride Occupational Health and Environmental Safety Division Number 20, April 1997 OSHA Regulation: 29 CFR 1910.1052; 1915.1052; 1926.1152 On January 10, 1997, The Occupational Safety and Health Administration (OSHA) issued a final rule for occupational exposure to methylene chloride (MC). Continued exposure may also cause eye and respiratory tract irritation. Exposure to methylene chloride may make symptoms of angina more severe. Skin exposure to liquid methylene chloride may cause irritation or chemical burns. Report any health signs and symptoms of exposure to methylene chloride to the responsible health professional. In 1976, NIOSH published a document entitled Criteria for a Recommended Standard …. The remainder of the animals of each species, sex, and exposure group were used in hematologic and cytogenetic studies (rats at 6 months only) and killed after either 6, 12, 15, or 18 months of exposures. Skin Protection: Wear chemical protective clothing e.g. However, unlike the data obtained from the first study which used higher doses, the carboxyhemoglobin response obtained in this study,13 indicated to the investigators, that the metabolism of methylene chloride is dose-related and saturable. Provide appropriate exhaust ventilation or control exposure by enclosed processes. Access to this website Therefore, overexposure to this substance can lead to carbon monoxide poisoning. Causes moderate to severe irritation. (t) Glutaraldehyde can cause occupational asthma and skin sensitization responses such as contact dermatitis. The environmental exposures varied from 0 to 350 ppm with a general decline in mean exposure concentrations from 118.8 ppm in 1966 to 40.3 ppm in 1975.

These latter data indicate that the pathway to produce carboxyhemoglobin had not been saturated at methylene chloride exposure concentrations as high as 1000 ppm. Provide eyewash and safety shower if contact or splash hazard exists. Though existing epidemiologic data derived from workers exposed to methylene chloride are inconclusive, the observation of cancers and tumors in both rats and mice treated with methylene chloride meets the criteria established in the Occupational Safety and Health Administration (OSHA) Cancer Policy for considering methylene chloride a “potential occupational carcinogen.” Therefore, the National Institute for Occupational Safety and Health (NIOSH) recommends that worker exposure to methylene chloride be controlled to the lowest feasible limit. Based on this evidence, methylene chloride exposure may be considered to be a weak mutagen in mammalian systems. Employees exposed to MC are at increased risk of developing cancer, adverse effects on the heart, central nervous system and liver, and skin or eye irritation. Wear chemical protective clothing if necessary. Chemical paint removers containing methylene chloride are widely used in domestic and industrial settings where exposure to a heat source with conversion to phosgene is possible.

Call a Poison Centre or doctor. There were 85 rats of each sex for each exposure group; 141 rats of each sex served as controls. Aerosol sprays and paint stripping may also cause significant nonoccupational exposures. The original report and subsequent updates cover a total of 20 years of follow-up (1964-1984). The incidence of the neoplasms was significant with respect to matched controls; however, the incidence of tumors was stated, by the investigators, to be within the range of tumor incidence rates among control animals from previous studies that had been conducted in the investigators’ laboratory. 1964. Because methylene chloride has been shown to induce increased numbers of benign and malignant neoplasms in rats and mice, it meets the criteria provided in the OSHA Cancer Policy for classifying a substance as a potential occupational carcinogen; therefore, NIOSH recommends that methylene chloride be considered a potential human carcinogen in the workplace. Occupational Exposure to Methylene Chloride. Signs & Symptoms of Overexposure: inhalation: nausea, headache, vomiting, numbness Methylene chloride toxicity is difficult to diagnose, as early symptoms are similar to those associated with many intoxicants; however, a rising carboxyhemoglobin level, despite removal of the patient from the source of exposure, is pathognomonic. First-aid measures General Advice If symptoms persist, call a physician. These symptoms will disappear shortly after exposure stops: Increased levels of carbon monoxide in the blood, which may cause fatigue, shortness of breath or chest pain Slurred speech. (in Canada and the United States). There was clear evidence of carcinogenicity of dichloromethane for female F344/N rats as shown by increased incidences of neoplasms of the mammary gland.”, In the study of B6C3F1 mice, a statistically significant increase in lung cancers (alveolar/bronchiolar carcinomas) and benign lung tumors (alveolar/bronchiolar adenomas) over controls was reported among males and females exposed at concentrations of 2000 or 4000 ppm. In 1976, the National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL) for methylene chloride was 75 ppm, 261 milligrams per cubic meter (mg/m3), as a TWA for up to a 10-hour workday, 40-hour workweek with a 500 ppm (1740 mg/m3) peak exposure concentration as determined over any 15-minute sampling period during the workday.
