Hazardous Ingredients

Hazardous % CAS LD50 LC50 Ingredients Number (species and route) Acetone 100 67-64-1 Oral-Rat: 5,800 mg/kg Inhalation-Rat: 50.1 g/m3/8 hr Dermal-Rabbit: 20,000 mg/kg . SECTION 3 – PHYSICAL DATA Physical State: Liquid Boiling Point: 56.5 C Freezing Point: -94.7 C Odour and Appearance: Odour Threshold: Evaporation Rate: Clear, Colourless Liquid 100-150 ppm ND (not determined) Sweet, pleasant odour Vapour Pressure: Vapour density: (air=1) Specific Gravity: 181.7 mmHg at 20 C 2 1.0 at 20C pH: NA (not applicable) Coefficient of water/oil distribution: ND (not determined) SECTION 4 – FIRE AND EXPLOSION DATA Flammability: Highly flammable and can be a severe fire hazard. The vapour easily forms explosive mixtures with air at room temperature. Extinguishing Media: dry chemical, carbon dioxide or foam Hazardous Combustion Products: Carbon monoxide Flashpoint: -17.8 C (closed cup) Autoignition Temperature: 578 C Upper Flammable Limit: 12.8% by volume Lower Flammable Limit: 2.6% by volume Explosion Data: Sensitivity to Mechanical Impact: Low Explosion Data: Sensitivity to Static Discharge: ND (not determined) SECTION 5 – REACTIVITY DATA Conditions under which unstable: Stable under normal conditions Incompatibility with other substances: May react with strong oxidizers such as peroxides and nitrates; halogenated hydrocarbon/alkali mixtures. Hazardous polymerization: Will not occur Conditions of reactivity: Strong oxidizers Hazardous decomposition products: Carbon monoxide SECTION 6 – TOXICOLOGICAL PROPERTIES Route of Entry: Skin contact, Eye contact, Inhalation, Ingestion Effects of acute exposure: May cause slight irritation to the skin. Severe irritant to the eyes. Primary route of exposure is inhalation of vapour; produces irritation of the upper respiratory tract. Prolonged exposure may cause headaches or dizziness. Ingestion may result in gastrointestinal irritation with possible nausea, vomiting, headache, dizziness, unconsciousness and injury to the kidneys and liver. Small amounts aspirated during vomiting may cause lung injury, possible death. Effects of chronic exposure: No known serious long-term effects. Long-term contact with the liquid removes natural oils from the skin. Irritancy: Liquid is mildly irritating on skin contact. Severe irritant to eyes. Sensitization: None known Carcinogenicity: No evidence of cardinogenicity Teratogenicity: No evidence of teratogenicity Reproductive Toxicity: No evidence of reproductive toxicity. Mutagenicity: No evidence of mutagenicity Toxicologically synergistic products: unknown SECTION 7 – PREVENTIVE MEASURES Engineering Controls to be used: Adequate ventilation to maintain air concentrations below exposure limits. General dilution ventilation may be adequate when acetone is used in small amounts at room temperature. Explosion-proof local exhaust ventilation is normally needed for large scale use or at elevated temperatures. Respiratory Protection: If local ventilation is inadequate, wear an air-purifying respirator equipped with organic vapour cartridges. In confined spaces or emergency situations wear self-contained breathing apparatus. Protective Clothing: Avoid skin contact. Wear neoprene, butyl or styrene-butadiene rubber gloves. Eye Protection: Splash-proof chemical goggles Other: An eyewash should be located near an area where acetone is routinely handled.
