Hazards identification : Liquefied gas.

Extremely flammable.

 

First aid measures

-Inhalation : In high concentrations may cause asphyxiation. Symptoms may include loss of

mobility/consciousness. Victim may not be aware of asphyxiation.

In low concentrations may cause narcotic effects. Symptoms may include dizziness, headache, nausea and loss of co-ordination.

Remove victim to uncontaminated area wearing self contained breathing apparatus. Keep victim warm and rested. Call a doctor. Apply artificial respiration if breathing stopped.

- Skin/eye contact : For liquid spillage - flush with water for at least 15 minutes.

-Ingestion : Ingestion is not considered a potential route of exposure.

 

Flammable class : Extremely flammable.

Specific hazards : Exposure to fire may cause containers to rupture/explode.

Hazardous combustion products : If involved in a fire the following toxic and/or corrosive fumes may be produced by thermal decomposition :

Carbonyl fluoride.

Carbon monoxide.

Hydrogen fluoride.

 

Extinguishing media

-Suitable extinguishing media : All known extinguishants can be used.

Specific methods : If possible, stop flow of product.

Move away from the container and cool with water from a protected position.

Do not extinguish a leaking gas flame unless absolutely necessary. Spontaneous/

explosive re-ignition may occur. Extinguish any other fire.

Special protective equipment for fire fighters: Use self-contained breathing apparatus and chemically protective clothing.

 

 

Personal precautions : Wear self-contained breathing apparatus when entering area unless atmosphere is proved to be safe.

Evacuate area.

Ensure adequate air ventilation.

Eliminate ignition sources.

 

Environmental precautions : Try to stop release.

Prevent from entering sewers, basements and workpits, or any place where its accumulation can be dangerous.

 

Clean up methods : Ventilate area.

 

Storage : Segregate from oxidant gases and other oxidants in store.

Keep container below 50°C in a well ventilated place.

 

Handling : Ensure equipment is adequately earthed.

 

Suck back of water into the container must be prevented.

Purge air from system before introducing gas.

Do not allow backfeed into the container.

Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. Contact your gas supplier if in doubt.

Keep away from ignition sources (including static discharges).

Refer to supplier's container handling instructions.

 

Personal protection : Ensure adequate ventilation.

Do not smoke while handling product.

 

Physical state at 20 °C : Liquefied gas.

Colour : Colourless gas.

Odo(u)r : Sweetish. Poor warning properties at low concentrations.

Relative density, gas (air=1) :2.9

Relative density, liquid (water=1) :1.2

Solubility in water [mg/l] : No reliable data available.

Flammability range [vol% in air] : 9.5 to 19

Auto-ignition temperature [°C] : Not known.

Other data : Gas/vapour heavier than air. May accumulate in confined spaces, particularly at or below ground level.

 

Stability and reactivity : Can form explosive mixture with air.

Thermal decomposition yields toxic products which can be corrosive in the presence of moisture.

May react violently with oxidants.

 

Toxicity information : No known toxicological effects from this product.

 

Ecological effects information : Not covered by the 'Montreal Protocol'.

Global warming factor [CO2=1] : 3800

 

General : Do not discharge into areas where there is a risk of forming an explosive mixture

with air. Waste gas should be flared through a suitable burner with flash back

arrestor.

Toxic and corrosive gases formed during combustion should be scrubbed before

discharge to atmosphere.

Do not discharge into any place where its accumulation could be dangerous.

Contact supplier if guidance is required.

Other transport information : Avoid transport on vehicles where the load space is not separated from the driver's compartment.

Ensure vehicle driver is aware of the potential hazards of the load and knows what to do in the event of an accident or an emergency.

Before transporting product containers :

- Ensure that containers are firmly secured.

- Ensure cylinder valve is closed and not leaking.

- Ensure valve outlet cap nut or plug (where provided) is correctly fitted.

- Ensure valve protection device (where provided) is correctly fitted.

- Ensure there is adequate ventilation.

- Compliance with applicable regulations.

 

EC Classification : Not included in Annex I.

Proposed by the industry.

F+; R12

 

EC Labelling

- Symbol(s) : F+ : Extremely flammable

- R Phrase(s) : R12 : Extremely flammable.

- S Phrase(s) : S9 : Keep container in a well-ventilated place.

S16 : Keep away from sources of ignition - No smoking.

S33 : Take precautionary measures against static discharges.

 

Ensure all national/local regulations are observed.

Ensure operators understand the flammability hazard.

Contact with liquid may cause cold burns/frostbite.

The hazard of asphyxiation is often overlooked and must be stressed during operator training.
