Ammonia Anhydrous (R717)

Remove the patient from the gas source. Remove prostheses such as false teeth. If not breathing, administer rescue breathing. If no pulse, administer CPR. If available, administer 100% oxygen. Monitor breathing and pulse continuously. Keep patient at rest in a semi-recumbent posture.

Symptoms: Headache, cough, bronchospasm, nausea, vomiting, pharyngeal and retrosternal pain, conjunctivitis. Severe inhalation produces laryngospasm, signs of upper airway obstruction (stridor, hoarseness, difficulty in speaking) and pulmonary oedema.

Flush body and clothes with large amounts of water. Remove contaminated clothing. For frost-bite: move to warmth, bathe in luke-warm water (not more than 35 deg C) for 10 to 15 minutes without rubbing. Apply clean, dry, light dressing. Raise and support limbs to reduce swelling.

Symptoms: Cold burns (frost-bite), potential necrosis.

Remove patient from gas source. Gently rinse affected eye(s) with clean, cool water for at least 15 minutes while holding eyelids open. Ensure patient looks up and side to side. Transport to hospital or doctor.

Symptoms: Conjunctivitis, potential corneal abrasion.

Contact a Poisons Information Centre or a doctor. Not considered a normal route of entry.

Symptoms: Nausea, vomiting.

Water spray or fog, foam, dry chemical powder, BCF (where regulations permit).

Containers may explode when heated - Ruptured cylinders may rocket. May burn but does not ignite easily. Fire exposed cylinders may vent contents through pressure relief devices thereby increasing vapour concentration. Fire may produce irritating, poisonous or corrosive gases. Runoff may create fire or explosion hazard. 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. May be violently or explosively reactive. Fight fire from a safe distance, with adequate cover.

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 full body clothing with breathing apparatus. 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.

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. Valve protection cap to be in place until cylinder is secured, connected. Cylinder must be properly secured either in use or in storage.

CARE: Explosive vapour air mixtures may be present on opening vessels which have contained liquid ammonia. Fatalities have occurred 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. Recommended materials: BUTYL/NEOPRENE, CPE, VITON/NEOPRENE, SARANEX-23. Ansell Glove Selection: AlphaTec® 02-100, AlphaTec® 58-735, AlphaTec® 15-554, TouchNTuff® 93-700, TouchNTuff® 92-500, TouchNTuff® 92-605, TouchNTuff® 93-250, AlphaTec® Solvex® 37-185, AlphaTec® 38-612.

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 K Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent). 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.

Overalls. PVC Apron. PVC protective suit may be required if exposure severe.

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