Potential health effects

ACUTE EXPOSURE The following acute (short term) health effects may occur immediately or shortly after exposure to this product: Exposure to this product can occur in the workplace or in the environment following releases to air, water, land, or groundwater. This product can enter the body when breathed in with contaminated air or when consumed with contaminated food or water. It can also be absorbed through skin contact. Effects of this product on human health and the environment depend on how much of the product is present and the length and frequency of exposure. Effects also depend on the health of a person or the condition of the environment when exposure occurs. Repeatedly breathing large amounts of Toluene, such as when "sniffing" glue or paint, can cause permanent brain damage. As a result, humans can develop problems with speech, hearing, and vision. Humans can also experience loss of muscle control, loss of memory, and decreased mental ability. Other studies show that repeat exposure to large amounts of hydrocarbon solvents adversely affects the nervous system, the kidneys, and the liver of animals. High vapor concentrations are irritating to the eyes and the respiratory tract, may cause coughing, headaches and dizziness, are anaesthetic and may have other central nervous system effects. Lower levels may cause trouble concentrating, headaches, and slowed reflexes. Very high levels can cause death. Narcotic effects occur at levels below the exposure standard. If a large amount ( > 1 ml/kg) is ingested and retained, symptoms of CNS depression and irritation occur and include weakness, dizziness, unconsciousness and convulsions. Corneal damage will occur after prolonged contact. Prolonged, repeated skin contact with low viscosity materials may de-fat the skin resulting in possible irritation and dermatitis. TARGET ORGANS : Central nervous system, eyes, skin, gastro-intestinal tract, blood, liver and kidneys ACUTE EXPOSURE (continued) SWALLOWED Considered an unlikely route of entry in commercial/industrial environments. The liquid is irritating and may be toxic if swallowed. Tends to break into a foam if the patient vomits. Ingestion can result in nausea, cramps, pain, vomiting, diarrhoea and central nervous system depression. Small amounts of liquid aspirated into respiratory system during ingestion or from vomiting may cause broncho-pneumonia or pulmonary oedema. If the victim is uncoordinated there is a greater likelihood of vomit entering the lungs and causing subsequent complications. EYE The vapor and the liquid are both severe eye irritants if exposure is prolonged. The liquid is highly irritating to the eyes and is capable of causing pain and severe conjunctivitis. The liquid is capable of causing corneal injury and severe damage with loss of sight if not promptly and adequately treated. SKIN Contact with the skin may result in severe irritation and drying of the skin which may lead to dermatitis if contact is prolonged. Toxic effects may result from skin absorption. Capable of causing skin sensitisation and allergic skin reactions. Open cuts, abraded or irritated skin should not be exposed to this material. The material may accentuate any pre-existing skin condition. INHALED This product is a central nervous system depressant. CNS depression characterised by dizziness and headache. Vapor/mist is extremely irritating to mucous membranes, upper respiratory tract and lungs. Inhalation hazard is increased at higher temperatures. Toxic effects are increased by consumption of alcohol. Repeated exposure may cause sensitisation and/or allergic reactions. Acute effects from inhalation of high concentrations of vapor are pulmonary irritation, including coughing, with nausea; central nervous system depression - characterized by headache, dizziness, increased reaction time, loss or co-ordination, fatigue, lassitude, irritability and gastrointestinal disturbances (e.g. nausea, anorexia and flatulence). If exposure to highly concentrated solvent atmosphere is prolonged this may lead to narcosis, unconsciousness, even coma and possible death. 3. continued CHRONIC EXPOSURE can occur at some time after exposure to liquid hydrocarbons and can last for months or years Repeated exposure may damage bone marrow, causing low blood cell count. Evidence from animal tests indicate that repeated or prolonged solvent inhalation exposures could result in kidney disorders, nervous system impairment, liver and blood changes. [PATTYS]. Repeated exposure to this product can cause headaches, loss of appetite, nausea, and liver and kidney damage, poor memory, difficulty in concentration and may cause brain damage. This chemical has not been adequately evaluated to determine whether brain or other nerve damage could occur with repeated exposure. However, many solvents and other petroleum based chemicals have been shown to cause such damage. Effects may include reduced memory and concentration, personality changes (withdrawal, irritability), fatigue, sleep disturbances, reduced coordination, and/or effects on nerves supplying internal organs (autonomic nerves) and/or nerves to the arms and legs (weakness, "pins and needles"). Repeated exposure can damage bone marrow, causing low blood cell count. Xylenes can damage the liver and kidneys. Repeated exposure to Xylenes can cause poor memory, difficulty in concentration and other brain effects. It can also cause damage to the surface of the eye and cause stomach problems. Prolonged or continuous skin contact with the liquid may cause de-fatting with drying, cracking, irritation and dermatitis following. Chronic Toluene habituation occurs following intentional abuse (glue sniffing) or from occupational exposure. Ataxia, incoordination and tremors of the hands and feet (as a consequence of diffuse cerebral atrophy), headache, abnormal speech, transient memory loss, convulsions, coma, drowsiness, reduced colour perception, frank blindness, nystagmus (rapid, involuntary eye movements), decreased hearing leading to deafness and mild dementia have all been associated with chronic abuse. SKIN Prolonged or repeated skin contact causes severe irritation and may lead to de-fatting and dermatitis. Capable of causing skin sensitisation and allergic skin reactions. MIXED EXPOSURES Because smoking can cause heart disease, as well as lung cancer, emphysema, and other respiratory problems, it may worsen respiratory conditions caused by chemical exposure. Even if you have smoked for a long time, stopping now will reduce your risk of developing health problems. Because more than light alcohol consumption can cause liver damage, drinking alcohol can increase the liver damage caused by liquid hydrocarbons. 4 .
