First-aid measures

Inhalation
Remove patient from exposure, keep warm and at rest. Oxygen may be beneficial if breathing is laboured or patient is cyanotic. Apply
artificial respiration if breathing has ceased or shows signs of failing.
Obtain immediate medical attention.
Skin Contact
Remove contaminated clothing. After contact with skin, wash immediately with plenty of water. If symptoms develop, obtain medical attention.
Eye Contact
Immediately irrigate with eyewash solution or clean water, holding the eyelids apart, for at least 10 minutes. Obtain medical attention.
Ingestion
Do not induce vomiting. Provided the patient is conscious, wash out mouth with water and give 200-300 ml (half a pint) of water to drink.
Obtain immediate medical attention.
Further Medical Treatment
Symptomatic treatment and supportive therapy as indicated. Adrenaline and similar sympathomimetic drugs should be avoided following
exposure as cardiac arrhythmia may result with possible subsequent cardiac arrest.

Fire-fighting measures

Extremely flammable. The gas is heavier than air and may travel a considerable distance to a source of ignition and flash back. Combustion will evolve toxic vapours (hydrogen chloride and carbon monoxide in addition to carbon dioxide).
Vinyl chloride is normally handled as a liquid under pressure. In fire conditions the pressure will increase. There is a danger of vessels or
pipework rupturing explosively, with the vinyl chloride expanding into a fireball.
Extinguishing Media For small fires, use water fog, CO2 or dry powder.
Large fires are difficult to extinguish and should not be attempted if there is a risk of further generation of an explosive cloud. If possible stop the flow and allow the fuel to die out. The fire may be restricted by use of expanded foam.
Fine water sprays should be used to cool vessels and pipework and for absorption of hydrogen chloride gas generated in the fire. Consideration should be given to the destination of the run-off water, which may be acidic.
Bulk water must not be used for fighting fires involving pools of liquid vinyl chloride, as this will increase the evaporation rate and the intensity of the fire.
Fire Fighting Protective Equipment A self contained breathing apparatus and full protective clothing must be worn in fire conditions.

Accidental release measures

Warn occupant downwind of potential fire or explosion hazard. Evacuate the area. Eliminate sources of ignition. Wear full protective equipment to prevent skin and eye contamination and inhalation of vapours. Provided it is safe to do so, isolate the source of the leak.
Contain liquid spillages. Do not allow spillages to enter drains, sewers, or waterways Adsorb spillages onto sand, earth or any suitable adsorbent material. Do not adsorb onto sawdust or other combustible materials.

Handling and storage

HANDLING
Avoid contact with eyes, skin and clothing. Do not breathe vapour.
Provide adequate ventilation, including appropriate local extraction, to ensure that the defined occupational exposure limit is not exceeded.
The vapour is heavier than air; beware of pits and confined spaces.
Avoid contact with naked flames and hot surfaces as there is a fire risk.
Ensure that equipment is properly earthed for dispersion of electrostatic charges.
Ensure that equipment is properly decontaminated before dismantling for maintenance, inspection etc.
STORAGE
Vinyl chloride is normally stored in carbon steel or stainless steel equipment. Keep in a cool well ventilated place away from sources of heat or ignition.Avoid contact with air or oxygen as potentially dangerous peroxides may be formed. An inhibitor (e.g. hydroquinone) may be required in some
situations to minimise the risk of peroxides initiating the polymerisation of vinyl chloride.

Please note: The requirements for the handling of vinyl chloride monomer using the conditions described in this section and in the relevant sections of the Chemical Safety Report refer to the use of this substance as a monomer for the manufacture of polymers and for the use of vinyl chloride as a chemical intermediate where handling according to Strictly Controlled Conditions is required.

Exposure controls / personal protection

Atmospheric concentrations should be minimised and kept as low as reasonably practicable below the occupational exposure limit.
Wear suitable protective clothing and eye/face protection.
Wear thermal insulating gloves and a face shield when handling liquified gases.
Wear suitable respiratory protective equipment if exposure to levels above the occupational exposure limit is likely.
For vinyl chloride, the most appropriate respiratory protective equipment is compressed air-line or self contained breathing apparatus.

Stability and reactivity

Incompatible materials: oxidising agents , aluminium and light alloys
Hazardous Reactions Can react violently if in contact with oxidising agents
Can react with air or oxygen to form vinyl polyperoxide which is shock and heat sensitive and will detonate under certain conditions.
May polymerise violently if exposed to air, oxygen or contaminants such as polyperoxides particularly at high temperatures.
Hazardous Decomposition Product(s) Thermal decomposition will evolve toxic and corrosive vapours. ( hydrogen chloride , Carbon Monoxide )

Disposal considerations

Disposal should be in accordance with local, state or national legislation.
Waste polyvinyl chloride slurry containing significant levels of residual vinyl chloride should be stripped of vinyl chloride prior to suitable treatment of the liquid waste for general disposal. Solid polyvinyl chloride waste should be preferably be dried before disposal. Disposal should be in accordance with local, state or national legislation.
