Accidental release measures

6.1. 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.
6.2. Environmental precautions
Discharge into the environment must be avoided.
6.3. 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

7.1. 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:
Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept handy.
7.2. Conditions for safe storage, including any incompatibilities
Segregate from alkalies and alkalizing substances.
Further information on storage conditions: 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.
Storage stability:
Storage temperature: < 20 °C
Storage duration: 6 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

8.1. Control parameters
Components with occupational exposure limits
75-44-5: phosgene; carbonyl chloride
TWA value 0.08 mg/m3 ; 0.02 ppm (OEL (EU))
STEL value 0.4 mg/m3 ; 0.1 ppm (OEL (EU))
592-34-7: butyl chloroformate; chloroformic acid butyl ester
8.2. 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 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
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
Do not breathe vapour/spray. Avoid contact with the skin, eyes and clothing. 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 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.

10.2. 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.
10.3. 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.
10.4. 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.
