STABILITY AND REACTIVITY <br />NORMALLY STABLE? (CONDITIONS TO AVOID): Stable <br />INCOMPATIBILITIES: Strong acids. Open flame. <br />HAZARDOUS DECOMPOSITION PRODUCTS: <br />Material does not decompose. Combustion products include carbon monoxide, oxides of nitrogen. <br />HAZARDOUS POLYMERIZATION: Will not occur <br />11. TOXICOLOGICAL INFORMATION <br />IMMEDIATE (ACUTE) EFFECTS: Possible skin irritation which is accentuated by sunlight. <br />DELAYED (SUBCHRONIC AND CHRONIC) EFFECTS: IARC has classified wood dust as a human carcinogen. <br />Normal handling of the creosote treated wood would not be expected to generate wood dust, but cutting, grinding <br />and/or other activities may generate wood dust. <br />OTHER DATA: <br />Persons with pre-existing disease or a history of ailments involving the skin or respiratory tract may be at a greater <br />than normal risk of developing adverse health effects from woodworking operations with this product. <br />The IARC monographs (Vol. 35) states that there is sufficient evidence for the carcinogenicity of creosote in <br />experimental animals. The NTP Annual Report on Carcinogens states that creosote oils are carcinogenic in <br />experimental animals. Creosote does not appear in the OSHA Subpart Z Table. Epidemiological studies of workers <br />in the woodtreating industry have shown no significant health effects due to occupational exposure to creosote. <br />Many cohort and case -control studies of cancer of the nasal cavities and paranasal sinuses have shown increased risks <br />associated with exposure to wood dust. Adenocarcinoma of the nasal cavities and paranasal sinuses is clearly <br />associated with exposure to hardwood dust. Occupational exposure to wood dust does not appear to have a causal <br />role in cancers of the oropharynx, hypopharynx, lung, lymphatic and haematopoietic systems, stomach, colon or <br />rectum. <br />No known ingredients which occur at greater than 0.1 %, other than those listed above, are listed as a carcinogen in <br />the IARC Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Humans, the NTP Annual Report <br />Current Issue Date: May, 1996 Page 5 of 7 <br />
