Highly flammable. May cause fire. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS

SWALLOWED ! The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion. ! The material has NOT been classified as "harmful by ingestion". This is because of the lack of corroborating animal or human evidence. ! Pyrophoric compounds may produce gastrointestinal damage resulting fromlocal generation of heat. 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. ! Pyrophoric compounds may produce thermal burns on contact with the eye. SKIN ! The material can produce chemical burns following direct contactwith the skin.

! Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions. ! Pyrophoric compounds can produce irritation with a range of severity. Deep burns can occur in severe cases, with shock. ! Open cuts, abraded or irritated skin should not be exposed to this material. ! 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 has NOT been classified as "harmful by inhalation" nor has it been designated as "irritating to the respiratory system". This is because of the lack of corroborating animal or human evidence. ! Pyrophoric compounds may decompose giving rise to potent irritants of therespiratory tract. ! Welding or flame cutting of metals with zinc or zinc dust coatings may result in inhalation of zinc oxide fume; high concentrations of zinc oxide fume may result in "metal fume fever"; also known as "brass chills", an industrial disease of short duration. [I. 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. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. Welding or flame cutting of metals with zinc or zinc dust coatings may result in inhalation of zinc oxide fume; high concentrations of zinc oxide fume may result in "metal fume fever"; also known as "brass chills", an industrial disease of short duration. [I.L.O] Symptoms include malaise, fever, weakness, nausea and may appear quickly if operations occur in enclosed or poorly ventilated areas.

PERSONAL PROTECTION

RESPIRATOR •Type AX Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent) EYE " Chemical goggles. " Full face shield. HANDS/FEET " When handling corrosive liquids, wear trousers or overalls outside of boots, to avoid spills entering boots. Suitability and durability of glove type is dependent on usage. Important factors in the selection of gloves include: such as: " frequency and duration of contact, " chemical resistance of glove material, " glove thickness and " dexterity Select gloves tested to a relevant standard (e.g. Europe EN 374, US F739, AS/NZS 2161.1 or national equivalent). " When prolonged or frequently repeated contact may occur, a glove with a protection class of 5 or higher (breakthrough time greater than 240 minutes according to EN 374, AS/NZS 2161.10.1 or national equivalent) is recommended. " When only brief contact is expected, a glove with a protection class of 3 or higher (breakthrough time greater than 60 minutes according to EN 374, AS/NZS 2161.10.1 or national equivalent) is recommended. " Contaminated gloves should be replaced. Gloves must only be worn on clean hands. After using gloves, hands should be washed and dried thoroughly. Application of a non-perfumed moisturiser is recommended. " Fire resistant/ heat resistant gloves where practical, otherwise " Heavy-duty chemically resistant gloves capable of providing short-term protection against spontaneous ignition. OTHER ! Wear protective clothing appropriate for the work situation. When handling liquids wear : " non-sparking shoes, " noncombustible or flameproof clothing. " Some plastic personal protective equipment (PPE) (e.g. gloves, aprons, overshoes) are not recommended as they may produce static electricity. " For large scale or continuous use wear tight-weave non-static clothing (no metallic fasteners, cuffs or pockets), non sparking safety footwear. ENGINEERING CONTROLS ! General exhaust is adequate under normal operating conditions. If risk of overexposure exists, wear an approved respirator. Inhalation risk of a pyrophoric material is low however risks of inhalation of combustion products may requires respiratory protection. It is recommended that this material be handled in a closed system or in a fume hood.

APPEARANCE Colourless, pyrophoric liquid which ignites in air burning with a blue flame and giving off a peculiar garlic-odour; reacts violently with water. Miscible with ether, benzene and other hydrocarbons. Terrestrial fate An estimated Koc value of 230, determined from a log Kow of 1.81, indicates that ethane is expected to have moderate mobility in soil. Volatilisation of ethane from moist soil surfaces is expected to be an important fate process given an estimated Henry's Law constant of 0.5 atm-cu m/mole derived from its vapor pressure, 31,500 mm Hg, and water solubility, 60.2 mg/L. Ethane is expected to volatilise from dry soil surfaces based upon its vapor pressure. Ethane was oxidized to ethanol in lake water and soil within 24 hours using cell suspensions from over 20 methyltrophic organisms. This suggests that biodegradation may be an important fate process. However ethane is a gas and therefore volatilisation is expected to be the most important fate process. Aquatic fate Based on an estimated Koc value ethane is not expected to adsorb to suspended solids and sediment. Volatilisation from water surfaces is expected based upon an estimated Henry's Law constant. Using this Henry's Law constant , volatilisation half-lives for a model river and model lake are estimated to be 34 min and 2.2 days, respectively. An estimated BCF of 5 derived from, from its log Kow suggests the potential for bioconcentration in aquatic organisms is low . Alkanes are generally resistant to hydrolysis. Ethane was oxidized to ethanol in lake water and soil within 24 hours using cell suspensions from over 20 methyltrophic organisms. Biodegradation may be an important fate process, however ethane is a gas and therefore volatilisation is expected to be the most important fate process(SRC). Material Value

Section 11 - TOXICOLOGICAL INFORMATION diethylzinc TOXICITY AND IRRITATION ! unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances. ! Asthma-like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a non-allergenic condition known as reactive airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating compound. Key criteria for the diagnosis of RADS include the absence of preceding respiratory disease, in a non-atopic individual, with abrupt onset of persistent asthma-like symptoms within minutes to hours of a documented exposure to the irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to severe bronchial hyperreactivity on methacholine challenge testing and the lack of minimal lymphocytic inflammation, without eosinophilia, have also been included in the criteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an infrequent disorder with rates related to the concentration of and duration of exposure to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that occurs as result of exposure due to high concentrations of irritating substance (often particulate in nature) and is completely reversible after exposure ceases. The disorder is characterised by dyspnea, cough and mucus production. ETHANE: DIETHYLZINC: ! No significant acute toxicological data identified in literature search. ZINC PEROXIDE: None available.

Disposal Instructions All waste must be handled in accordance with local, state and federal regulations. $ For small quantities: " Cautiously add the material to dry butanol in an appropriate solvent. " Reaction may be vigorous and exothermic. Legislation addressing waste disposal requirements may differ by country, state and/ or territory. Each user must refer to laws operating in their area. In some areas, certain wastes must be tracked. A Hierarchy of Controls seems to be common - the user should investigate: " Reduction " Reuse " Recycling " Disposal (if all else fails) This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use. If it has been contaminated, it may be possible to reclaim the product by filtration, distillation or some other means. Shelf life considerations should also be applied in making decisions of this type. Note that properties of a material may change in use, and recycling or reuse may not always be appropriate. DO NOT allow wash water from cleaning equipment to enter drains. Collect all wash water for treatment before disposal. " Recycle wherever possible or consult manufacturer for recycling options. " Consult Waste Management Authority for disposal.
