HAZARDS IDENTIFICATION *** Colourless liquid or crystals, with a camphor-like odour.FLAMMABLE AND VAPOUR. Vapour is heavier than air and may spread long distances. Distant ignition and flashback are possible. Central nervous system depressant. High vapour concentrations may cause headache, nausea, dizziness, drowsiness, incoordination and confusion. Very high vapour concentrations may cause unconsciousness and death. May cause eye irritation. Aspiration hazard. Swallowing or vomiting of the liquid EFFECTS OF SHORT-TERM (ACUTE) EXPOSURE : tert-Butyl alcohol is a central nervous system depressant. High concentrations can cause irritation of the nose and throat, headache, dizziness, drowsiness, confusion and unconsciousness. No minimum concentrations at which these effects occur have been reported. exposure to concentrations less than 100 ppm is not likely to produce these effects. No ill effects due to occupational exposures have The potency for intoxicatin is approximately 1.5 times that of Direct contact with tert-butyl alcohol only caused slight swelling and redness.(5) SKIN SENSITIZATION: tert-Butyl alcohol caused an allergic reaction in a 58 year old patient who used a skin screen containing alcohol. A patch tests was positive for tert-butyl alcohol.(5) Exposure to liquid is likely to cause irritation. High vapour concentrations are irritating. Related alcohols, such as n-butyl Ingestion of a large amount is likely to have effects similar to related alcohols, such as n-butyl alcohol, if ingested tert-butyl aspirated into the lungs, it may cause severe lung damage (edema), respiratory and cardiac arrest and possibly death. EFFECTS OF LONG-TERM (CHRONIC) EXPOSURE : There have been no reports of specific health effects due to long-term exposure to tert-butyl alcohol SKIN: Repeated or prolonged contact may drying, reddening and cracking of the skin (dermatitis) No human information. Developmental toxicity was seen at doses which tert-Butyl alcohol gave negative results in one bacterial assay and in TOXICOLOGICALLY SYNERGISTIC MATERIALS : Alcohols may interact synergistically with chlorinated solvents (e.g. tetrachloride), aromatic hydrocarbons (e.g. xylene) or dithiocarbamates Probably does not accumulate. tert-Butyl is rapidly absorbed into the It is slowly broken down in the body. It is excreted in exhaled air and the urine. Several days may be required for complete removal from the In general, the toxicity of tert-butyl alcohol is thought to be very to the other butyl alcohols. Some animal evidence indicates that tert-butyl alcohol may increase the acute inhalation toxicity of carbon Remove source of contamination or move victim to fresh air. Remove contamination or move victim to fresh air. If breathing has stopped, personnel should begin artificial respiration (AR) or, if the heart has stopped, cardiopulmonary resuscitation (CPR) immediately. Obtain As quickly as possible, flush with lukewarm, gently flowing water for least 5 minutes or until the chemical is removed. Quickly and gently brush away excess chemical. Wash gently and thoroughly with water and non-abrasive soap for 5 minutes or until chemical is removed. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for at least 20 minutes, or until the chemical is removed while holding the eyelid(s) open. If irritation persists, obtain medical NEVER give anything by mouth if victim is rapidly losing consciousness, unconscious or is convulsing. DO NOT INDUCE VOMITING. Have victim drink to 300 mL (8 to 10 oz.) of water to dilute material in stomach. If occurs naturally, have victim lean forward to reduce risk of Repeat administration of water. If breathing has stopped, trained should begin artificial respiration (AR) or, if the heart has stopped, cardiopulmonary resuscitation (CPR) immediately. Quickly transport Provide general supportive measures (comfort, warmth, rest). Consult a doctor and/or the nearest Poison Control Centre for all exposures minor instances of inhalation or skin contact. All first aid procedures should be periodically reviewed by a doctor familiar with the material its conditions of use in the workplace. *** SECTION 5.

TOXICOLOGICAL INFORMATION *** SKIN IRRITATION: Prolonged contact with rabbit skin failed to cause INHALATION: tert-Butyl alcohol is irritating to the mucous membranes very high concentrations.(1) tert-Butyl alcohol, like the other butyl alcohols, is a central nervous system depressant and the signs of intoxication in animals exposed to its vapour are similar to the other butyl alcohols, i.e. ataxia (muscular incoordination) and narcosis. It a stronger narcotic action upon animals than has normal or isobutyl ORAL: Eighteen repeated daily narcotic doses were not fatal to rats, and no harmful effects resulted from a long-continued, easily The degree of central nervous system depression was measured in rats an inclined plane test which assesses balance. Using this test, alcohol was found to be 4.8 times more intoxicating than ethanol, only by 1-butanol. Recovery was very slow, with no improvement in performance 7 hours after administration.(1). It seems that tert-butyl alcohol is broken down very slowly in the Six rats were fed a high dose (40% of the LD50) of tert-butyl alcohol. After 16 to 18 hours, they were exposed to a high concentration (1,000 carbon tetrachloride for 2 to 2 1/2 hours. Exposure to the alcohol increased the effects of carbon tetrachloride MUTAGENICITY: tert-Butyl alcohol gave negative results in a bacterial assay, the mouse lymphoma assay and the cultured Chinese hamster ovary assay for increased frequency of chromosomal aberrations and TERATOGENICITY AND EMBRYOTOXICITY: Pregnant mice (3 groups of 15) were 0.50, 0.75 or 1.00% (w/v) tert-butyl alcohol from day 6 to day 20 of pregnancy. A developmental delay in physiological and psychomotor performance scores was seen in the offspring. It was not established if this delay in central nervous system was due to permanent or temporary damage. There were signs of toxicity *** SECTION 12.
