Section 2 - HAZARDS IDENTIFICATION CHEMWATCH HAZARD RATINGS Min Max Flammability: 1 Toxicity: 3 Body Contact: 3 Min/Nil=0 Low=1 Reactivity: 2 Moderate=2 High=3 Chronic: 3 Extreme=4 CANADIAN WHMIS SYMBOLS 1 of 13 EMERGENCY OVERVIEW RISK Causes burns. Risk of serious damage to eyes. May impair fertility. Possible risk of harm to the unborn child. Toxic in contact with skin and if swallowed. Risk of explosion if heated under confinement. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS SWALLOWED ! Toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 40 gram may be fatal or may produce serious damage to the health of the individual. ! The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion. ! After oral dosing of hexafluoroacetone in rats, moderate to severe CNS depression persisting for several days was noted. No other signs were discernible. On gross necropsy, no abnormalities were evident. EYE ! The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating. ! If applied to the eyes, this material causes severe eye damage. ! Undiluted hexafluoroacetone sesquihydrate was instantly painful and produced a severe extensive injury in the rabbit eye. When rinsed with water 20 seconds after instillation, the eye appeared to return to normal 29 days after exposure except for a small corneal injury with local vascularisation. The unwashed eye showed extensive corneal opacity, scar tissue, pannus, and chronic conjunctivitis. SKIN ! Skin contact with the material may produce toxic effects; systemic effectsmay result following absorption. ! The material can produce chemical burns following direct contactwith the skin. ! Undiluted hexafluoroacetone sesquihydrate is a severe skin irritant as expected by its acidic (pH = 1) nature. Concentrations below 50% produced mild to no irritation on rabbit skin. The irritation response at higher concentrations included definite erythema that became scaly and developed crusts 1 to 5 days postapplication. One drop of undiluted dihydrate produced marked erythema and blanching to guinea pig skin, but no irritation was seen with dilutions of 0.1 to 10%. After dermal application, there was no measurable amount of material remaining on the skin of the rabbits at the end of the exposure period. The exposed area was erythematous and scaly and developed crusts (eschar formation) 2 to 5 days after exposure. Mild CNS depression preceded death, but no other abnormal signs were evident. On gross necropsy, no abnormalities were present except for discolouration and oedema of the exposed skin. ! Fluorides are easily absorbed through the skin and cause death of soft tissue and erode bone. Healing is delayed and death of tissue may continue to spread beneath skin. ! Open cuts, abraded or irritated skin should not be exposed to this material. ! Solution of material in moisture on the skin, or perspiration, may markedly increase skin corrosion and accelerate tissue destruction. ! Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. INHALED ! If inhaled, this material can irritate the throat andlungs of some persons. ! The material is not thought to produce adverse health effects following inhalation (as classified using animal models). Nevertheless, adverse effects have been produced following exposure of animals by at least one other route and good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting. ! Symptoms of exposure may be burning sensation, coughing, wheezing, shortness of breath, headache, nausea, vomiting. An acute severe inhalation exposure may be fatal as a result of spasm, inflammation and edema of larynx, chemical pneumonitis and pulmonary oedema. For hexafluoroacetone dihydrate, the maximum concentration causing irritation of the upper respiratory tract was reported to be 32 mg/m3 (equivalent to 26 mg/m3 hexafluoroacetone). After inhalation exposure by rats, depression of the central nervous system (CNS) was manifest as hind leg instability and loss of postural and righting reflexes . The effects persisted for several hours. Most of the fatalities occurred 2 to 6 days after exposure. There was little, if any, lung damage. There were no histological findings in heart, kidney, or liver. ! Acute effects of fluoride inhalation include irritation of nose and throat, coughing and chest discomfort. A single acute over-exposure may even cause nose bleed. <\p>. CHRONIC HEALTH EFFECTS ! Repeated or prolonged exposure to corrosives may result in the erosion of teeth, inflammatory and ulcerative changes in the mouth and necrosis (rarely) of the jaw. Bronchial irritation, with cough, and frequent attacks of bronchial pneumonia may ensue. <\p>. Ample evidence exists from experimentation that reduced human fertility is directly caused by exposure to the material. Results in experiments suggest that this material may cause disorders in the development of the embryo or fetus, even when no signs of poisoning show in the mother. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or 2 of 13 biochemical systems. Animal testing with the gas at 12 ppm for rats and dogs (13 weeks @ 6 hour) showed testicular degeneration and atrophy, hyperglycaemia, anemia. In reproduction toxicity studies in which pregnant rats were exposed during organogenesis, minimal but statistically significant decreases in female offspring body weight were seen at exposure by inhalation to 0.76 mg/m3, and a higher incidence of hydronephrosis, one anophthalmic foetus and 2 stunted fetuses at a dermal dose of 0.75 mg /kg bw , the lowest concentration/dose tested. Hydrogen fluoride easily penetrates the skin and causes destruction and corrosion of the bone and underlying tissue. Ingestion causes severe pains and burns in the mouth and throat and blood calcium levels are dangerously reduced. <\p>.

" Urgent hospital treatment is likely to be needed. EYE ! If this product comes in contact with the eyes: " Immediately hold eyelids apart and flush the eye continuously with running water. " Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. SKIN ! If skin or hair contact occurs: " Immediately flush body and clothes with large amounts of water, using safety shower if available. " Quickly remove all contaminated clothing, including footwear. INHALED " If fumes or combustion products are inhaled remove from contaminated area. " Lay patient down. Keep warm and rested. NOTES TO PHYSICIAN ! Treat symptomatically. for poisons (where specific treatment regime is absent): ----------------------------------------------------------------------------------------------------------------BASIC TREATMENT ---------------------------------------------------------------------------------------------------------------- " Establish a patent airway with suction where necessary. " Watch for signs of respiratory insufficiency and assist ventilation as necessary. Following acute or short term repeated exposure to hydrofluoric acid: " Subcutaneous injections of Calcium Gluconate may be necessary around the burnt area. Continued application of Calcium Gluconate Gel or subcutaneous Calcium Gluconate should then continue for 3-4 days at a frequency of 4-6 times per day. If a "burning" sensation recurs, apply more frequently. " Systemic effects of extensive hydrofluoric acid burns include renal damage, hypocalcemia and consequent cardiac arrhythmias. Monitor hematological, respiratory, renal, cardiac and electrolyte status at least daily. Tests should include FBE, blood gases, chest X-ray, creatinine and electrolytes, urine output, Ca ions, Mg ions and phosphate
