HAZARDS IDENTIFICATION HEALTH HAZARD DATA: The major effect of exposure to this product is headache, drowsiness, irritation of the eyes and nose, and lungs. Target organs include the respiratory system, nervous system, and mucous membranes. HAZARDS OF COMBUSTION PRODUCTS: Carbon monoxide and carbon dioxide can be found in the combustion products of this product and other forms of hydrocarbon combustion. Carbon monoxide in moderate concentrations can cause symptoms of headache, nausea, vomiting, increased cardiac output, and confusion. Exposure to higher concentrations of carbon monoxide can cause loss of consciousness, heart damage, brain damage, and/or death. Exposure to high concentrations of carbon dioxide can cause simple asphyxiation by displacing available oxygen. Combustion of this and other similar materials should only be carried out in well ventilated areas. The National Kerosene Heater Association has released preliminary test results that indicate no increased emissions of carbon monoxide or nitrogen dioxide resulted from using red-dyed kerosene in new generation heaters. MEDICAL CONDITION GENERALLY AGGRAVATED BY EXPOSURE: Medical conditions which have the same symptoms and effects as those outlined under the health hazard information section can be aggravated by exposure to this product. MEDICAL LIMITATION: N/A ROUTES OF EXPOSURE INHALATION: Irritation of the upper respiratory tract and eyes, with possible euphoria, dizziness, headache, incoordination, ringing in the ears, convulsions, coma, and respiratory arrest. SKIN CONTACT: Defatting of the skin may occur with continued and prolonged contact. Irritation and burning sensation may occur on exposure to the liquid or mists, as well as the possibility of blisters. Hair loss can occur upon chronic exposure. SKIN ABSORPTION: Not significant. EYE CONTACT: Severe burning sensation with temporary irritation and swelling of lids. INGESTION: Irritation of the mucous membranes of throat, esophagus and stomach which may result in nausea and vomiting; central nervous system depression may occur, if absorbed (see Inhalation symptoms above). If aspirated, chemical pneumonitis may occur with potentially fatal results. EFFECTS OF OVEREXPOSURE ACUTE: See above. CHRONIC: May cause dermatitis. Animal studies have shown development of cancerous tumours, but no correlation in humans has been established. CARCINOGENICITY INFORMATION Kerosene is not listed as carcinogenic by NTP, OSHA, and ACGIH. IARC has listed kerosene as a probable human carcinogen (2A). MUTAGENICITY/TERATOGENICITY/ REPRODUCTIVE TOXICITY INFORMATION Mutagenicity: Not a mutagen. Teratogenicity: No teratogenic effects are observed.

SPECIAL FIRE FIGHTING PROCEDURES: Pressure-demand, self-contained breathing apparatus should be provided for fire fighters in buildings or confined areas where this product is stored. Storage containers exposed to fire should be kept cool with water spray. UNUSUAL FIRE AND EXPLOSION HAZARD: Vapour accumulation is possible, and flashback can occur with explosive force if vapours are ignited. Transfer to and from commonly grounded containers. SENSITIVITY TO STATIC DISCHARGE /MECHANICAL IMPACT: May accumulate static charge. No sensitivity to impact. 6. ACCIDENTAL RELEASE MEASURES If material is spilled, steps should be taken to contain liquid and prevent discharges to streams or sewer systems and control or stop the loss of volatile materials to the atmosphere. Remove ignition sources. Absorb spilled material with non-combustible materials such as cat litter, dirt, sand, or petroleum sorbent pads/pillows. Do not use combustible materials like rags, wood chips, or sawdust. Remove contaminated materials to an appropriate disposal container. For large spills dike spill area with sand or dirt to contain material and cover sewers/drains. Remain upwind and keep unnecessary people away. Contact trained emergency response team for cleanup. Remove liquid using grounded suction pumps, isolate hazard area, and deny entry. Spills or releases should be reported, if required to the appropriate local, provincial, and federal regulatory agencies. 7. HANDLING AND STORAGE INFORMATION Store only in approved containers.
