Guidance on Safe Use
Administrative data
First-aid measures
Product-Specific hazards:
Extremely flammable liquefied gas.
An asphyxiant at high concentrations – oxygen depletion can be fatal.
Contact with the liquid may result in frostbite.
General advice :
Warning before intervention:
Before attempting to rescue casualties, isolate area from all potential sources of ignition including disconnecting electrical supply.
Ensure adequate ventilation and check that a safe, breathable atmosphere is present before entry into confined spaces.
Take care to self-protect by avoiding becoming contaminated – use approved positive pressure air supplied breathing apparatus with a full facepiece.
Move contaminated patient(s) out of the dangerous area.
Seek medical assistance - show the material safety data sheet or label if possible.
Inhalation :
Symptom(s): Exposure to high concentrations may cause asphyxiation.
Move to fresh air.
Do not leave the victim unattended.
Keep patient warm and at rest. If unconscious place in recovery position.
Seek immediate medical attention.
If breathing is difficult, give oxygen if possible, or assisted ventilation.
In the event of cardiac arrest, (no pulse), apply cardiopulmonary resuscitation.
Skin contact :
Symptom(s): Contact with product in liquid form may cause frostbite.
Do not remove clothing that adheres due to freezing.
Immediately flush affected area with plenty of water – continue for at least 15 minutes.
If there are signs of frostbite, (blanching or redness of skin or burning or tingling sensation), do not rub, massage or compress the affected area. Send the casualty immediately to hospital .
Eye contact :
Symptom(s): Contact with product in liquid form may cause frostbite.
Remove any contact lenses.
Flush eyes with water thoroughly and continuously for at least 15 minutes.
Keep eye wide open while rinsing.
If there are signs of frostbite, pain, swelling, lachrimation or photophobia persists, the patient should be seen in a specialist health care facility.
Ingestion :
Is not considered a likely route of exposure – frostbite to the lips and mouth may occur if in contact with the liquid.
Advice to Physician :
A simple asphyxiant gas at normal temperatures and pressures – there is no specific antidote.
In the event of contact with product in liquid form treat for frostbite.
Fire-fighting measures
Where possible stop the flow of gas.
If the flow cannot be stopped allow the fire to burn out, whilst cooling containers and surroundings with a water spray.
Suitable extinguishing media :
LARGE FIRE: Use water spray, water fog or foam.
SMALL FIRE: Dry powder or carbon dioxide (CO2) extinguisher, dry sand or fire fighting foam.
Unsuitable Extinguishing Media :
Do NOT use water jet.
Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam.
Combustion Products :
Carbon monoxide, carbon dioxide and unburned hydrocarbons (smoke).
Specific hazards during fire fighting :
Vapour is denser than air – flashback may be possible over considerable distances.
Cylinders or other containment vessels may explode under fire conditions - use water spray to cool unopened containers.
Do not allow run-off from fire fighting to enter drains or water courses – may cause explosion hazard in drains and may reignite.
Further information :
Special protective equipment for fire-fighters :
Wear an approved positive pressure self-contained breathing apparatus in addition to standard fire fighting gear.
Accidental release measures
General information:
Spillages of material generate large volumes of extremely flammable gas which is heavier than air and will accumulate in low areas or confined spaces.
Stop leak if safe to do so. Avoid direct contact with released material and breathing vapours. Stay upwind.
Keep non-involved personnel away from the area of spillage. Alert emergency personnel.
Enter area only if strictly necessary. A combustible gas detector can be used to check for flammable gas or vapours.
Eliminate all ignition sources if safe to do so (e.g. electricity, sparks, fires, flares, etc.).
If required, notify relevant authorities according to applicable regulations.
Personal precautions :
Wear personal protective equipment, including self contained breathing apparatus, unless the atmosphere is proved to be safe.
Environmental precautions :
Land spillage :
Prevent further leakage or spillage if safe to do so.
Prevent spillage from entering drains or any place where accumulation may occur.
Ensure adequate ventilation, especially in confined areas.
Spillages in water or at sea :
Prevent further leakage or spillage if safe to do so.
Spillages of liquid product in the water will likely result in a quick and complete vaporization of the product. Isolate the area and prevent fire/explosion hazard for ships and other structures, taking into account wind direction and speed, until the material is completely dispersed.
If the spillage contaminates rivers, lakes or drains inform respective authorities.
Methods for clean up :
Contain spillage – ventilate area and allow to evaporate.
Further accidental release measures :
Spillages of liquid product will create a fire hazard and form an explosive atmosphere.
Ensure all equipment is non sparking or electrically bonded.
Dispose of wastes safely.
Handling and storage
Risk of explosive mixtures of vapour and air.
Advice on safe handling :
Consider technical advances and process upgrades (including automation) for the elimination of releases.
Minimise exposure using measures such as closed systems, dedicated facilities and suitable general/local exhaust ventilation.
Drain down systems and clear transfer lines prior to breaking containment.
Clean/flush equipment, where possible, prior to maintenance.
Consider the need for risk based health surveillance.
Ensure safe systems of work or equivalent arrangements are in place to manage risks.
Regularly inspect, test and maintain all control measures.
Smoking, eating and drinking should be prohibited.
Use only in well ventilated areas.
Avoid all sources of ignition, oxidising agents, chlorine and hydrogen chloride or hydrogen fluoride..
Take precautionary measures against static discharges, use proper bonding and/or grounding procedures.
Use piping and equipment designed to withstand the pressures to be encountered.
Use a check valve or other protective device to prevent reverse flow.
Cleaning, inspection and maintenance of the internal structure of storage tanks must be done only by properly equipped and qualified personnel as defined by national, local or company regulations.
Handle empty containers with care; vapour residue may be flammable.
Do not pressurise, cut, weld, braze, solder, drill, or grind on containers.
Dispose of rinse water in accordance with local and national regulations.
The vapour is heavier than air, beware of accumulation in pits and confined spaces.
Ensure that all relevant regulations regarding explosive atmospheres, and handling and storage facilities of flammable products are followed.
Storage :
To store only in supplied cylinders or approved vessels.
No smoking.
Store in a designated cool and well-ventilated place.
Cylinders should be secured vertical - and only transported in a secure position in a well ventilated vehicle or hand truck.
Cylinders which have been are opened must be carefully resealed and kept upright.
For maintenance work or conservation, emptied tanks should be purged, and blanketed with inert gas (i.e. nitrogen).
Additional indications:
(If Applicable – Substance registered as isolated intermediate under SCC): This substance is handled under Strictly Controlled Conditions in accordance with REACH regulation Article 17(3) for on-site isolated intermediates and, in case the substance is transported to other sites for further processing, the substance should be handled at these sites under the Strictly Controlled Conditions as specified in REACH regulation Article 18(4). Site documentation to support safe handling arrangements including the selection of engineering, administrative and personal protective equipment controls in accordance with risk-based management systems is available at each manufacturing site.
