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

Fire-fighting measures
Suitable extinguishing media: dry powder, carbon dioxide, alcohol-resistant foam
Unsuitable extinguishing media for safety reasons: water
The product is sparingly soluble in water and is only covered.
Special hazards arising from the substance or mixture: hydrogen chloride, phosgene; carbonyl chloride, carbon oxides, halogenated compounds
Special protective equipment for fire-fighters: 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
Wear a self-contained breathing apparatus. Avoid contact with the skin, eyes and clothing. Keep people away and stay on the upwind side.
Discharge into the environment must be avoided.
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
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.
Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept handy.
Segregate from alkalies and alkalizing substances.
Protect from direct sunlight. Keep only in the original container. Frequently check condition of drums (increase in pressure, bulging, rust). Keep container tightly closed in a cool, well-ventilated place. Product has to be immediately consumed or disposed of, if signs of pressure increase or bulging are being detected at a drum. Protect against moisture. Protect against heat. Storage at a proportionate temperature is required, to avoid 'breathing' of containers.
Keep only in the original container in a cool, dry, well-ventilated place away from ignition sources, heat or flame.

Exposure controls / personal protection
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 for short-term contact (recommended: At least protective index 2, corresponding > 30 minutes of permeation time according to EN 374)
fluoroelastomer (FKM) - 0.7 mm coating thickness
butyl rubber (butyl) - 0.7 mm coating thickness
nitrile rubber (NBR) - 0.4 mm coating thickness
Eye protection: Tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield.
Do not breathe vapour/spray. Avoid contact with the skin, eyes and clothing. The substance was registered as a transported isolated intermediate. When processing large amounts. 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.

Stability and reactivity
Corrodes metals in the presence of water.
Reacts with water/air.
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: > 40 °C
Avoid all sources of ignition: heat, sparks, open flame. Avoid direct sunlight. Avoid electro-static charge. Avoid humidity. Avoid heat. Disregard of the conditions mentioned may result in undesirable decomposition reactions. Avoid excessive temperatures. Avoid contamination.
Incompatible materials: alkaline reactive substances, alcohols, bases, amines, iron compounds, heavy metal salts, water
Hazardous decomposition products: hydrogen chloride, Carbon dioxide, 1-chlorobutane; butyl chloride
