R500

Remove the patient from the gas source or contaminated area. PPE, including positive pressure self-contained breathing apparatus may be required. Remove prostheses such as false teeth. If not breathing, administer rescue breathing. If no pulse, administer CPR. Administer 100% oxygen if available. Summon an emergency ambulance. Keep patient warm, comfortable and at rest.

Immediately remove all contaminated clothing, including footwear. Flush skin and hair with running water (and soap if available). Seek medical attention in event of irritation.

Symptoms: Irritation.

Remove from gas source. Gently rinse with clean, cool water for at least 15 minutes. Tilt head back, pour water from inner to outer corners. Ensure patient looks up and side to side. Transport to hospital or doctor. If light sensitive, protect with a clean, loosely tied bandage.

Symptoms: Great pain, light sensitivity.

Not considered a normal route of entry. Contact a Poisons Information Centre or a doctor. Avoid giving milk, oils, or alcohol. 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.

Heating may cause expansion or decomposition leading to violent rupture of containers. May emit corrosive, poisonous fumes. 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. Vented gas is more dense than air and may collect in pits, basements.

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.

Minor Spills: Avoid breathing vapour and any contact with liquid or gas. DO NOT enter confined spaces where gas may have accumulated. Increase ventilation. Major Spills: Clear area of all unprotected personnel and move upwind. Alert Emergency Authority and advise them of the location and nature of hazard. Remove leaking cylinders to a safe place. Fit vent pipes. Release pressure under safe, controlled conditions. Burn issuing gas at vent pipes. DO NOT exert excessive pressure on valve; DO NOT attempt to operate damaged valve.

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. Remove leaking cylinders to a safe place. Fit vent pipes. Release pressure under safe, controlled conditions. Burn issuing gas at vent pipes. DO NOT exert excessive pressure on valve; DO NOT attempt to operate damaged valve.

Environmental hazard - contain spillage.

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.

Store below 38 deg. C. Cylinders should be stored in a purpose-built compound with good ventilation, preferably in the open. 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. Cylinder must be properly secured either in use or in storage. Valve protection cap to be in place until cylinder is secured, connected.

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.

Butyl rubber gloves. Butyl rubber gloves should be used when handling halogenated aliphatics. Nitrile, PVC-coated nitrile, and PVC protective equipment are not recommended. When handling sealed and suitably insulated cylinders wear cloth or leather gloves.

Safety glasses with side shields. Chemical goggles. [AS/NZS 1337.1, EN166 or national equivalent]. 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. Cartridge performance is affected by humidity. 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. 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.
