First-aid measures

1 Description of first aid measures
General information:
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 face piece.
Move contaminated patient(s) out of the dangerous area.
Seek medical assistance - Show the material safety data sheet or label if possible.
(Subject to applicability) A high hydrogen sulphide (H2S) and/or carbon monoxide (CO) content may cause specific hazard conditions.

Following inhalation:
Move exposed person to fresh air.
Do not leave the victim unattended.
Keep person warm and at rest.
If the casualty is unconscious, place in the recovery position.
Call a doctor immediately.
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.
(1) Remove casualty to fresh air as quickly as possible.
(2) Immediately begin artificial respiration if breathing has ceased.
(3) Obtain medical advice for further treatment.

Following skin contact:
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.

Following eye contact:
Rinse opened eye for several minutes under running water. Then consult a doctor.
Remove contact lenses, if possible.
If there are signs of frostbite, pain, swelling, lachrimation or photophobia persists, or in case of damage from high pressure jets, the patient should be seen in a specialist health care facility.

Following ingestion/aspiration:
Not considered a likely route of exposure.
Frostbite to the lips and mouth may occur if in contact with the liquid.

2 Most important symptoms and effects, both acute and delayed
Exposure to high concentrations may cause asphyxiation.
Contact with product in liquid form may cause frostbite (skin/eye). Ingestion is not considered a likely route of exposure.
Notes for the doctor:
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 (hydrogen sulphide) or CO ( carbon oxide), follow the specific protocols.

Fire-fighting measures

1 Extinguishing media
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:
Water spray.
Water fog (specifically trained personnel only).
Foam.
SMALL FIRE:
Carbon dioxide.
Dry chemical powder.
Dry sand. Fire fighting foam.

Unsuitable extinguishing media:
Do not use direct water jets on the burning product.
Simultaneous use of foam and water on the same surface is to be avoided.

2 Special hazards arising from the substance or mixture
In case of insufficient cooling of containers:
BLEVE (Boiling Liquid Expanding Vapour Explosion): Complete rupture of the container followed by ignition and explosion of the mass.
Hazardous combustion products:
Carbon Dioxide (CO2).
Carbon monoxide (CO).
Unburned hydrocarbons(smoke).

3 Advice for fire-fighters
Other 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.

Specific fire-fighting methods:
Standard fire fighting gear.
Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks engulfed in fire.
For massive fire, use unmanned hose holders or monitor nozzles.
If it is impossible to put out the fire, withdraw from area and let fire burn.

Accidental release measures

1 Personal precautions, protective equipment and emergency procedures
Eliminate possible causes of ignition if safe to do so (e.g. electricity, sparks, fires, flares).
Prevent entry into waterways, sewers, basements or confined areas.
Stop leak if safe to do so.
Keep non-involved personnel away from the area of spillage. Alert emergency personnel.
Enter area only if strictly necessary.
A gas detector can be used to check for flammable gas or vapours.
If required, notify relevant authorities according to applicable regulations.

1.1 For non-emergency personnel
Avoid direct contact with released material and breathing vapours.
Stop all work that requires an open flame, stop all vehicles, and stop all machines and equipment that may cause sparks or flames.
All equipment used when handling the product must be grounded. Stay upwind.

1.2 For emergency responders
Spillages of material generate large volumes of extremely flammable gas which is heavier than air and will accumulate in low areas or confined spaces.
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.
(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.


2 Environmental precautions
SPILLAGES ON TO LAND
Prevent seepage into sewage system, workpits and cellars.
Stop or contain leak at the source, if safe to do so.
When inside buildings or confined spaces, ensure adequate ventilation.
SPILLAGES IN WATER OR AT SEA.
Stop or contain leak at the source, 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.
Prevent fire/explosion hazard for ships and other structures in the area, taking into account wind direction and speed, until the material is completely dispersed.
Inform respective authorities in case of seepage into water course or sewage system.


3. Methods and material for containment and cleaning up

Handling and storage

1 Precautions for safe handling
GENERAL INFORMATION
Risk of explosive mixtures of vapour and air. Ensure that all relevant regulations regarding explosive atmospheres, and handling and storage facilities of flammable products, are followed.
Minimise exposure using measures such as closed systems, dedicated facilities and suitable general/ local exhaust ventilation.
Cleaning, inspection and maintenance of internal structure of storage tanks must be done only by properly equipped and qualified personnel as defined by national, local or company regulations.
Consider the need for risk based health surveillance.
(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.

1.1 Protective measures
Use only in well ventilated areas.
Consider technical advances and process upgrades (including automation) for the elimination of releases.
Drain down systems and clear transfer lines prior to breaking containment.
Clean/flush equipment, where possible, prior to maintenance.
Ensure safe systems of work or equivalent arrangements are in place to manage risks. Regularly inspect, test and maintain all control measures.
Avoid all sources of ignition, oxidising agents, chlorine and hydrogen chloride or hydrogen fluoride.
Use piping and equipment designed to withstand the pressures to be encountered.
Use a check valve or other protective device to prevent reverse flow.
Handle empty containers with care; vapour residue may be flammable.
Take precautionary measures against static discharges, use proper bonding and/or grounding procedures.

Measures to protect the environment:
Spillages of material generate large volumes of extremely flammable gas which is heavier than air and will accumulate in low areas or confined spaces.
Use explosion-proof apparatus / fittings and spark-proof tools.
Use tools/equipment electrically bonded. Dispose of wastes safely.
