Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
Following exposure to gas, remove the patient from the gas source or contaminated area. NOTE: Personal Protective Equipment (PPE), including positive pressure self-contained breathing apparatus may be required to assure the safety of the rescuer. Prostheses such as false teeth, which may block the airway, should be removed, where possible, prior to initiating first aid procedures. 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:
Not specified.
🖐️ Skin Contact
If skin contact occurs: 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:
Not specified.
👁️ Eye Contact
Open the eyelid(s) wide to allow the material to evaporate. 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. The patient may be in great pain and wish to keep the eyes closed. It is important that the material is rinsed from the eyes to prevent further damage. Ensure that the patient looks up, and side to side as the eye is rinsed in order to better reach all parts of the eye(s). Transport to hospital or doctor. Even when no pain persists and vision is good, a doctor should examine the eye as delayed damage may occur. If the patient cannot tolerate light, protect the eyes with a clean, loosely tied bandage. Ensure verbal communication and physical contact with the patient. DO NOT allow the patient to rub the eyes DO NOT allow the patient to tightly shut the eyes DO NOT introduce oil or ointment into the eye(s) without medical advice DO NOT use hot or tepid water.
Symptoms:
Not specified.
🍽️ Ingestion/Swallowing
Not specified.
Symptoms:
Not considered a normal route of entry.
🚨 Immediate Medical Attention Required
Maintain an open airway and assist ventilation if necessary. Treat coma and arrhythmias if they occur. Avoid (adrenaline) epinephrine or other sympathomimetic amines that may precipitate ventricular arrhythmias. Tachyarrhythmias caused by increased myocardial sensitisation may be treated with propranolol, 1-2 mg IV or esmolol 25-100 microgm/kg/min IV. Monitor the ECG for 4-6 hours.
Medical Treatment
There is no specific antidote. Administer activated charcoal, if available. DO NOT induce vomiting because of rapid absorption and the risk of abrupt onset CNS depression. Administer activated charcoal, although the efficacy of charcoal is unknown. Perform gastric lavage only if the ingestion was very large and recent (less than 30 minutes).
Fire Fighting Measures & Emergency Response
Fire suppression methods, extinguishing media, and firefighting safety procedures
✅ Suitable Extinguishing Media
Dry chemical, CO2 or water spray to extinguish gas (only if absolutely necessary and safe to do so).
❌ Unsuitable Extinguishing Media
DO NOT use water jets.
⚠️ Specific Fire Hazards
HIGHLY FLAMMABLE: will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Fire exposed containers may vent contents through pressure relief valves thereby increasing fire intensity and/or vapour concentration. Vapours may travel to source of ignition and flash back. Containers may explode when heated - Ruptured cylinders may rocket. Fire may produce irritating, poisonous or corrosive gases. Combustion products include: carbon monoxide (CO), carbon dioxide (CO2), hydrogen fluoride, other pyrolysis products typical of burning organic material.
🔥 Fire Fighting Instructions
FOR FIRES INVOLVING MANY GAS CYLINDERS: To stop the flow of gas, specifically trained personnel may inert the atmosphere to reduce oxygen levels thus allowing the capping of leaking container(s). Reduce the rate of flow and inject an inert gas, if possible, before completely stopping the flow to prevent flashback. DO NOT extinguish the fire until the supply is shut off otherwise an explosive re-ignition may occur. If the fire is extinguished and the flow of gas continues, use increased ventilation to prevent build-up of explosive atmosphere. Alert Fire Brigade and tell them location and nature of hazard. Consider evacuation. Fight fire from a safe distance, with adequate cover.
🛡️ Firefighter Protection Equipment
Wear breathing apparatus plus protective gloves.

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 containing another gas.
• Avoid generation of static electricity.
• Earth all lines and equipment.
• DO NOT transfer gas from one cylinder to another.
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. 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. 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.
