SECTION 11 TOXICOLOGICAL INFORMATION IMMEDIATE HEALTH EFFECTS Eye Irritation: The eye irritation hazard is based on evaluation of data for similar materials or product components. Skin Irritation: The skin irritation hazard is based on evaluation of data for similar materials or product. components. Skin Sensitization: This material did not cause skin sensitization reactions in a Buehler guinea pig test. Acute Dermal Toxicity: LD50: >5ml/kg (rabbit). Acute Oral Toxicity: LD50: > 5 ml/kg (rat) Acute Inhalation Toxicity: 4 hour(s) LC50: >5mg/I (rat). ADDITIONAL TOXICOLOGY INFORMATION: This product contains gas oils. CONCAWE (product dossier 951107) has summarized current health, safety and environmental data available for a number of gas ails, typically hydradesuifurized middle distillates, CAS 64742-80-9, straight-run middle distillates, CAS 64741-44-2, and/or light cat-cracked distillate CAS 64741-59-9. CARCINOGENICITY:All materials tested have caused the development of skin tumors in mice, but all featured severe skin irritation and sometimes a long latency period before tumors developed. Straight-run and cracked gas oil samples were studied to determine the influence of dermal irritation on the carcinogenic activity of middle distillates. At non-irritant doses the straight-run gas coil was not carcinogenic, but at irritant doses,weak activity was demonstrated. Cracked gas oils, when diluted with mineral oil, demonstrated carcinogenic activity irrespective of the occurrence of skin irritation. Gas oils were tested on male mice to study tumor initiating/promoting activity. The results demonstrated that while a straight-run gas oil sample was neither an initiator or promotor, a blend of straight-run and FCC stock Id was both a tumor initiator and a promoter. GENOTOXICITY: Hydrotreated &hydrodesulfurized gas oils range in activity from inactive to weakly positive in in-vitro bacterial mutagenicity assays. Mouse lymphoma assays on straight-run gas oils without subsequent hydrode su[ph urization gave positive results in the presence of S9 metabolic activation. In-vivo bone marrow cytogenetics and sister chromatic exchange assay exhibited no activity for straight-run components with or without hydrodesulphurization. Thermally-or catalytically cracked gas oils tested with in-vitro bacterial mutagenicity assays in the presence of S9 metabolic activation were shown to be mutagenic. in-vitro sister chromatic exchange assays on cracked gas oil gave equivocal results both with and without S9 metabolic activation. In-vivo bone marrow cytogenetics assay was inactive for two cracked gas oil samples.Three hydrocracked gas oils were tested with in-vitro bacterial mutagenicity assays with S9, and one of the three gave positive results. Twelve distillate fuel samples were tested with in-vitro bacterial mutagenicity assays &with S9 metabolic activation and showed negative to weakly positive results. In one series, activity was shown to be related to the PCA content of samples tested. Two in-vivo studies were also conducted. A mouse dominant lethal assay was negative for a sample of diesel fuel. in the other study, 9 samples of No 2`heating oil containing 50% cracked stocks caused a slight increase in the number of chromosomal aberrations in bone marrow cytogenetics assays. DEVELOPMENTAL TOXICITY: Diesel fuel vapor did not cause fetotoxic or teratogenic effects when pregnant rats were exposed on days 6-15 of pregnancy. Gas oils were applied to the skin of pregnant rats daily on days 0-19 of gestation. All but one (coker light gas oil) caused fetotoxicity (increased resorptions, reduced litter weight, reduced litter size) at dose levels that were also maternally toxic. This product may contain significant amounts of Polynuclear Aromatic Hydrocarbons (PAH's)which have been shown to cause skin cancer after prolonged and frequent contact with the skin of test animals.
