First-aid measures

Product-Specific hazards:
Extremely flammable liquefied gas.
May cause cancer and genetic defects.
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.
(Subject to applicability) a high hydrogen sulphide (H2S) and/or carbon monoxide (CO) content may cause specific hazard conditions

Where there is potential for exposure: restrict access to authorised persons; provide specific activity training to operators to minimise exposures.
Wear suitable gloves and coveralls to prevent skin contamination.
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.
(Subject to applicability: If there is any suspicion of inhalation of H2S or CO, rescuers must wear breathing apparatus, belt and safety rope, and follow rescue procedures. Remove casualty to fresh air as quickly as possible. Immediately begin artificial respiration if breathing has ceased. Obtain medical advice for further treatment).


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.
(Subject to applicability: In case of effects from inhalation of H2S or CO, follow the specific protocols.)

Fire-fighting measures

Where possible stop the flow of gas and if safe to do so.
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 :
In case of a large fire or in confined or poorly ventilated spaces wear full fire resistant protective clothing and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode 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.
(Subject to applicability): When the presence of dangerous amounts of H2S and/or CO around the spilled product is suspected or proved, additional or special actions may be warranted, including access restrictions, use of special protection equipment, procedures and personnel training.

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

Obtain special instructions before use.
Risk of explosive mixtures of vapour and air.
(Subject to applicability) A specific assessment of inhalation risks from the presence of H2S and/or CO in tank headspaces, confined spaces, product residue, tank waste and waste water, and unintentional releases must be made to help determine controls appropriate to local circumstances.

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 transport information
Preamble
0.1 The transportation of dangerous goods (by land, water or air) is a specialized professional field. Dangerous goods transport is regulated by an extensive body of recommendations, regulations, rules and agreements to ensure an adequate and harmonised level of safety for man and environment. Whereas some of these requirements have been adopted as European Union legislation, others are legally binding international treaties or sector agreements. They cover all the relevant technical aspects involved in the transport of dangerous goods (e.g. choice of equipment, labelling, documentation, packaging design, testing procedures, operating procedures etc.).
0.2 In addition to legal obligations discussed in the previous paragraph, Member states will also have in place detailed binding regulations governing the general conduct of transport activities, including licensing and inspection of vehicles, the authorization of drivers and other personnel, and issues relating to the rules of the road. There may also be specific national exceptions and requirements.
0.3 The legal framework and its accompanying detailed provisions will specify which actions are necessary/mandatory, advisable or forbidden. Extensive repetition of this background information is not practicable in a safety data sheet, and could make the document too long and difficult to read and understand, especially in an emergency when clear, brief information is needed.
0.4 The consideration of this background information enables the content of the safety data sheet to be concentrated on the identification of a product's proper shipping name and its hazard classification. Where it is relevant, other information may be added. This information will act as key for the professional for retrieving the necessary specific information in the relevant body of transport codes, rules and regulations.
0.5 Substances in this category may be classified differently. Factors affecting classification include composition, initial boiling point and vapour pressure. The differences are explained in additional transport information paragraphs that have been numbered.

Additional transport information 02
There is a hierarchy in the choice of proper shipping name. Specific substances names take precedence over N.O.S. names for specific types of chemical that in turn take precedence over generic N.O.S. names. Hydrocarbon gas, liquefied consists of hydrocarbon gas from natural gas or from distillations of petroleum which are liquefied by pressure. The use of UN 1965 requires the proper shipping name to incorporate the technical name. According to section 3.1.2.8.1 of the UN Model Regulations (15th revised edition) the technical name shall be a recognized chemical or other name used in scientific and technical handbooks, journals and texts. For land transport (ADR/RID) and inland waterway transport the technical name could be Mixture A, Mixture A01, Mixture A02, Mixture A1, Mixture B1, Mixture B2, Mixture B, Mixture C, propane, butane or the chemical name(s) of not more than two of the constituents which most predominantly contribute to the hazard(s). For marine transport (IMDG), air transport (ICAO/IATA) the technical name could be propane, butane or the chemical name(s) of not more than two of the constituents which most predominantly contribute to the hazard(s).
