R449A

Remove the patient from the gas source or contaminated area. Remove prostheses such as false teeth. If not breathing spontaneously, administer rescue breathing. If no pulse, administer CPR. If available, administer 100% oxygen. Monitor breathing and pulse continuously.

Symptoms: Respiratory insufficiency, pulmonary oedema, seizures.

Flush skin and hair with running water (and soap if available). For frost-bite: Move casualty into warmth before thawing. Bathe affected area in luke-warm water (not more than 35 deg C) for 10 to 15 minutes without rubbing. Apply a clean, dry, light dressing of fluffed-up dry gauze. Raise and support limbs to reduce swelling. Transport to hospital or doctor.

Symptoms: Cold burns (frost-bite), subsequent blackening of tissue indicating potential necrosis.

Remove patient from gas source. Take to nearest eye wash or source of clean water. Open eyelids wide to allow material to evaporate. Gently rinse with clean, cool water for at least 15 minutes while tilting head back. Ensure patient looks up and side to side. Protect eyes with a clean, loosely tied bandage if light sensitive. Transport to hospital or doctor.

Symptoms: Great pain, potential for delayed damage.

Not considered a normal route of entry. Contact a Poisons Information Centre or a doctor. Administer activated charcoal if available. DO NOT induce vomiting.

SMALL FIRE: Use extinguishing agent suitable for type of surrounding fire. LARGE FIRE: Cool cylinder.

DO NOT direct water at source of leak or venting safety devices as icing may occur.

Containers may explode when heated - Ruptured cylinders may rocket. Fire exposed containers may vent contents through pressure relief devices. High concentrations of gas may cause asphyxiation without warning. May decompose explosively when heated or involved in fire. Contact with gas may cause burns, severe injury and/ or frostbite. Contains low boiling substance: Closed containers may rupture due to pressure buildup under fire conditions.

Alert Fire Brigade and tell them location and nature of hazard. Fight fire from a safe distance, with adequate cover. Use water delivered as a fine spray to control fire and cool adjacent area.

Clear area of all unprotected personnel and move upwind. Alert Emergency Authority and advise them of the location and nature of hazard.

Avoid breathing vapour and any contact with liquid or gas. Protective equipment including respirator should be used. DO NOT enter confined spaces where gas may have accumulated. Increase ventilation.

Clear area of all unprotected personnel and move upwind. Alert Emergency Authority and advise them of the location and nature of hazard. Wear breathing apparatus and protective gloves. Prevent by any means available, spillage from entering drains and water-courses.

Prevent by any means available, spillage from entering drains and water-courses.

Consider use in closed pressurised systems, fitted with temperature, pressure and safety relief valves which are vented for safe dispersal. Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. The tubing network design connecting gas cylinders to the delivery system should include appropriate pressure indicators and vacuum or suction lines. Fully-welded types of pressure gauges, where the bourdon tube sensing element is welded to the gauge body, are recommended. Before connecting gas cylinders, ensure manifold is mechanically secure and does not containing another gas. DO NOT transfer gas from one cylinder to another.

Storage temperature: <52 deg.c>. Cylinders should be stored in a purpose-built compound with good ventilation, preferably in the open. Such compounds should be sited and built in accordance with statutory requirements. The storage compound should be kept clear and access restricted to authorised personnel only. Cylinders stored in the open should be protected against rust and extremes of weather.

Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection. The basic types of engineering controls are: Process controls which involve changing the way a job activity or process is done to reduce the risk. Enclosure and/or isolation of emission source which keeps a selected hazard "physically" away from the worker and ventilation that strategically "adds" and "removes" air in the work environment.

When handling sealed and suitably insulated cylinders wear cloth or leather gloves. Insulated gloves: NOTE: Insulated gloves should be loose fitting so that may be removed quickly if liquid is spilled upon them. Insulated gloves are not made to permit hands to be placed in the liquid; they provide only short-term protection from accidental contact with the liquid.

Chemical goggles. Full face shield may be required for supplementary but never for primary protection of eyes. Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing the wearing of lenses or restrictions on use, should be created for each workplace or task.

Type AX Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent). Cartridge respirators should never be used for emergency ingress or in areas of unknown vapour concentrations or oxygen content. The wearer must be warned to leave the contaminated area immediately on detecting any odours through the respirator. The odour may indicate that the mask is not functioning properly, that the vapour concentration is too high, or that the mask is not properly fitted. Because of these limitations, only restricted use of cartridge respirators is considered appropriate. Cartridge performance is affected by humidity. Cartridges should be changed after 2 hr of continuous use unless it is determined that the humidity is less than 75%, in which case, cartridges can be used for 4 hr. Used cartridges should be discarded daily, regardless of the length of time used. Positive pressure, full face, air-supplied breathing apparatus should be used for work in enclosed spaces if a leak is suspected or the primary containment is to be opened (e.g. for a cylinder change). Air-supplied breathing apparatus is required where release of gas from primary containment is either suspected or demonstrated.

Protective overalls, closely fitted at neck and wrist.

• Unstable in the presence of incompatible materials. • Product is considered stable. • Hazardous polymerisation will not occur.
