Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
If the patient is not breathing spontaneously, administer rescue breathing. If the patient does not have a pulse, administer CPR. If medical oxygen and appropriately trained personnel are available, administer 100% oxygen. Summon an emergency ambulance. If an ambulance is not available, contact a physician, hospital, or Poison Control Centre for further instruction. Keep the patient warm, comfortable and at rest while awaiting medical care. MONITOR THE BREATHING AND PULSE, CONTINUOUSLY. Administer rescue breathing (preferably with a demand-valve resuscitator, bag-valve mask-device, or pocket mask as trained) or CPR if necessary.
Symptoms:
Following exposure to gas, remove the patient from the gas source or contaminated area.
🖐️ Skin Contact
Flush skin and hair with running water (and soap if available). Seek medical attention in event of irritation.
Symptoms:
If skin contact occurs: Immediately remove all contaminated clothing, including footwear.
👁️ Eye Contact
Gently rinse the affected eye(s) with clean, cool water for at least 15 minutes. Have the patient lie or sit down and tilt the head back. Hold the eyelid(s) open and pour water slowly over the eyeball(s) at the inner corners, letting the water run out of the outer corners. Protect the eyes with a clean, loosely tied bandage if the patient cannot tolerate light.
Symptoms:
Even when no pain persists and vision is good, a doctor should examine the eye as delayed damage may occur.
🍽️ Ingestion/Swallowing
For advice, contact a Poisons Information Centre or a doctor. Avoid giving milk or oils. Avoid giving alcohol.
Symptoms:
Not considered a normal route of entry.
🚨 Immediate Medical Attention Required
Use of adrenaline and other catecholamines may be contraindicated due to possible cardiac sensitisation. Treat as for asphyxia.
Medical Treatment
Consider orotracheal or nasotracheal intubation for airway control in unconscious patient or where respiratory arrest has occurred. Positive-pressure ventilation using a bag-valve mask might be of use. Start an IV D5W TKO. If signs of hypovolaemia are present use lactated Ringers solution.
Fire Fighting Measures & Emergency Response
Fire suppression methods, extinguishing media, and firefighting safety procedures
✅ Suitable Extinguishing Media
Use extinguishing agent suitable for type of surrounding fire. Cool cylinder.
❌ Unsuitable Extinguishing Media
Do not direct water at source of leak or venting safety devices as icing may occur.
⚠️ Specific Fire Hazards
Heating may cause expansion or decomposition leading to violent rupture of containers. May emit corrosive, poisonous fumes. High concentrations of gas may cause asphyxiation without warning. May decompose explosively when heated or involved in fire.
🔥 Fire Fighting Instructions
Alert Fire Brigade and tell them location and nature of hazard. Wear breathing apparatus and protective gloves. Fight fire from a safe distance, with adequate cover. Use water delivered as a fine spray to control fire and cool adjacent area.
🛡️ Firefighter Protection Equipment
Wear breathing apparatus and protective gloves. Fight fire from a safe distance, with adequate cover.
Accidental Release Measures & Spill Response
Emergency spill cleanup procedures, containment methods, and environmental protection
💧 Small Spill Procedures
Avoid breathing vapour and any contact with liquid or gas. Increase ventilation.
🌊 Large Spill Procedures
Burn issuing gas at vent pipes. DO NOT exert excessive pressure on valve; DO NOT attempt to operate damaged valve.
🌍 Environmental Precautions
Prevent by any means available, spillage from entering drains and water-courses.

Safe Handling & Storage Procedures
Industrial handling precautions, storage conditions, and workplace safety requirements
⚠️ Handling Precautions
• 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 contain another gas.
• DO NOT transfer gas from one cylinder to another.
🏪 Storage Conditions
• Ensure the use of equipment rated for cylinder pressure.
• Ensure the use of compatible materials of construction.
• Valve protection cap to be in place until cylinder is secured, connected.
• Cylinder must be properly secured either in use or in storage.
Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
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.
🧤 Hand Protection
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.
👁️ Eye Protection
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.
😷 Respiratory Protection
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. Selection of the Class and Type of respirator will depend upon the level of breathing zone contaminant and the chemical nature of the contaminant. Protection Factors (defined as the ratio of contaminant outside and inside the mask) may also be important. 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.
