First-aid measures

Description of first aid measures
Immediately remove contaminated clothing. If the patient is likely to become unconscious, place and
transport in stable sideways position (recovery position). First aid personnel should pay attention to
their own safety.
On skin contact:
Immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist.
On contact with eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open,
consult an eye specialist.
On ingestion:
Immediately rinse mouth and then drink 200-300 ml of water, seek medical attention.
Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific
antidote, administer corticosteroid dose aerosol to prevent pulmonary odema. Medical monitoring for
at least 24-48 hours.

hydrogen chloride, phosgene; carbonyl chloride, carbon oxides, halogenated compounds
The substances/groups of substances mentioned can be released in case of fire.
Advice for fire-fighters
Special protective equipment:
Wear self-contained breathing apparatus and chemical-protective clothing.
Further information:
Suppress gases/vapours/mists with water spray jet. Fire debris must be disposed of in accordance
with offical regulations.

Accidental release measures

The product is irritating to eyes even at low concentrations in the air.
Personal precautions, protective equipment and emergency procedures
Wear a self-contained breathing apparatus. Avoid contact with the skin, eyes and clothing. Keep
people away and stay on the upwind side.
Environmental precautions
Discharge into the environment must be avoided.
Methods and material for containment and cleaning up
For large amounts: Pump off product. Dispose of absorbed material in accordance with regulations.
For residues: Pick up with suitable absorbent material. Dispose of absorbed material in accordance
with regulations.

Handling and storage

Precautions for safe handling
Ensure thorough ventilation of stores and work areas. Protect against moisture. Use only in enclosed
systems. Adequate extraction of the vapours is necessary when working with open containers. In
case of insufficient ventilation, wear suitable respiratory equipment.
Protection against fire and explosion:
Keep away from sources of ignition - No smoking. Take precautionary measures against static
Conditions for safe storage, including any incompatibilities
Segregate from alkalies and alkalizing substances.
Further information on storage conditions: Protect from direct sunlight. Protect against heat. Keep
only in the original container. Keep container tightly closed and dry; store in a cool place. Frequently
check condition of drums (increase in pressure, bulging, rust). Product has to be immediately
consumed or disposed of, if signs of pressure increase or bulging are being detected at a drum.
Storage stability:
Storage temperature: < 20 °C
Storage duration: 12 Months
If the stated storage temperature is exceeded the shelf life can be reduced.
From the data on storage duration in this safety data sheet no agreed statement regarding the
warrantee of application properties can be deduced.
Improper storage may result in pressure build up in the drums.
Keep only in the original container in a cool, dry, well-ventilated place away from ignition sources,
heat or flame.
Storage stability is based upon ambient temperatures and conditions described.

Exposure controls / personal protection

Control parameters

No DNEL value available.
Exposure controls
Personal protective equipment
Respiratory protection:
Breathing protection if gases/vapours are formed. Gas filter for gases/vapours of organic compounds
(boiling point >65 °C, e. g. EN 14387 Type A) Suitable respiratory protection for higher
concentrations or long-term effect: Self-contained breathing apparatus.
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials short-term contact and/or splashes (recommended: At least protective index 2,
corresponding > 30 minutes of permeation time according to EN 374)
butyl rubber (butyl) - 0.7 mm coating thickness
fluoroelastomer (FKM) - 0.7 mm coating thickness
Supplementary note: The specifications are based on tests, literature data and information of glove
manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g.
temperature) it must be considered, that the practical usage of a chemical-protective glove in
practice may be much shorter than the permeation time determined through testing.
Manufacturer's directions for use should be observed because of great diversity of types.
Eye protection:
Tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield.
Body protection:
Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting
boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case
of dust).
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Avoid inhalation of vapour. The substance was
registered as a transported isolated intermediate. The manufacturer/importer has received the
confirmation by the user that the substance is used under strictly controlled conditions in accordance
with art. 18 of the REACH regulation (EC) No 1907/2006.

Chemical stability
Even when products are stored appropriately a slowly decomposition reaction takes place. If the
storage conditions and duration are taken into account, no hazard is caused by the product.
Possibility of hazardous reactions
At elevated temperatures gas forming exothermic decomposition reaction may occur. The formation
of gaseous decomposition products builds up pressure in tightly closed containers if the product is
greatly overheated. Evolution of corrosive gases/vapours. Reacts with water and basic components
to generate heat. Reacts with activated carbon. Reacts with alkalies and metals. Reacts with
alcohols, amines, aqueous acids and alkalies. Reacts with water and moisture, with formation of
hydrogen chloride. Partly very violent reactions with bases and numerous organic classes of
substances such as alcohols and amines. Impurities promote decomposition. Energy is released
when reacting with e.g. acids, alkaline reacting substances, amines or catalysts. ppm traces of heavy
metals reduce the onset temperature and lead to instability and exothermic product release with gas
formation. Vapours may form ignitable mixture with air.
Conditions to avoid
Temperature: > 39 °C
Avoid all sources of ignition: heat, sparks, open flame. Avoid direct sunlight. Avoid electro-static
charge. Avoid humidity. Avoid heat. Avoid prolonged storage. Disregard of the conditions mentioned
may result in undesirable decomposition reactions. Avoid excessive temperatures. Avoid
Incompatible materials
Substances to avoid:
alkaline reactive substances, alcohols, bases, amines, iron compounds, heavy metal salts, water
Hazardous decomposition products
Hazardous decomposition products:
chloroethane, hydrogen chloride, Carbon dioxide, methanol

Disposal considerations
