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.

If inhaled:

Keep patient calm, remove to fresh air, seek medical attention. Immediately administer a corticosteroid from a controlled/metered dose inhaler.

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.

Most important symptoms and effects, both acute and delayed

Symptoms: irritation of respiratory tract, dyspnea, coughing, development of pulmonary edema, cyanosis, The onset of symptoms is delayed for up to 24 hours after uptake.

Indication of any immediate medical attention and special treatment needed

Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote. Pulmonary odema prophylaxis. Medical monitoring for at least 24 hours.

Fire-fighting measures

Further information:

Fire debris must be disposed of in accordance with offical regulations. Suppress gases/vapours/mists with water spray jet.

Accidental release measures

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.

Reference to other sections

Information regarding exposure controls/personal protection and disposal considerations can be found in the related sections.

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.

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. 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.

Protect from temperatures above: 40 °C

The packed product must be protected against exceeding the indicated temperature.

Exposure controls / personal protection

Personal protective equipment

Respiratory protection:

Breathing protection if gases/vapours are formed. Suitable respiratory protection for lower concentrations or short-term effect: 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 ISO 374-1)

Performance level 6, corresponding to a breakthrough time of >480 min according to EN ISO 374-1

nitrile rubber (NBR) - 0.4 mm coating thickness

fluoroelastomer (FKM) - 0.7 mm coating thickness

Performance level 4, corresponding to a breakthrough time of >120 min according to EN ISO 374-1

polyvinylchloride (PVC) - 0.7 mm coating thickness

butyl rubber (butyl) - 0.7 mm coating thickness

Performance level 3, corresponding to a breakthrough time of >60 min according to EN ISO 374-1

chloroprene rubber (CR) - 0.5 mm coating thickness

Performance level 1, corresponding to a breakthrough time of >10 min according to EN ISO 374-1

natural rubber/natural latex (NR) - 0.5 mm coating thickness

Manufacturer's directions for use should be observed because of great diversity of types.

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.

Eye protection:

Tightly fitting safety goggles (splash goggles) (e.g. EN 166)

Body protection:

Body protection must be chosen based on level of activity and exposure., full protection suit with breathing-air supply (f.e. according to EN 943)

General safety and hygiene measures

Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray. Wearing of closed work clothing is required additionally to the stated personal protection equipment. 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. When using, do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift. Gloves must be inspected regularly and prior to each use. Replace if necessary (e.g. pinhole leaks). Take off immediately all contaminated clothing. Wash contaminated clothing before reuse. Store work clothing separately.

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: > 50 °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 contamination.

Incompatible materials

Substances to avoid:

alkaline reactive substances, alcohols, bases, amines, iron compounds, heavy metal salts, water.

Hazardous decomposition products:

hydrogen chloride, carbon dioxide, 2-Ethylhexan-1-ol, 3-(Chloromethyl)heptane.

Disposal considerations

Waste treatment methods

Incinerate in suitable incineration plant, observing local authority regulations.

Hydrolysis with alkali / ammonia solution in water.

Esterification with methanol and afterwards incineriation in a suitable incineration facility.

This product and any uncleaned containers must be disposed of as hazardous waste.

Contaminated packaging:

Be careful when handling empty packing which is not decontaminated and rinsed.

Decontamination of product residues with sodium hydroxide solution / ammonia solution in water.
