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.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention. Immediately inhale corticosteroid dose
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.
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

Extinguishing media
Suitable extinguishing media:
dry powder, carbon dioxide, foam
Unsuitable extinguishing media for safety reasons:
Special hazards arising from the substance or mixture
hydrogen chloride, nitrogen oxides, carbon oxides
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:
Fire debris must be disposed of in accordance with offical regulations.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Breathing protection required. Avoid contact with the skin, eyes and clothing.
Environmental precautions
Do not empty into drains.
Methods and material for containment and cleaning up
For small amounts: Contain with absorbent material (e.g. sand, silica gel, acid binder, general purpose
binder, sawdust). Dispose of absorbed material in accordance with regulations.
For large amounts: Contain with absorbent material (e.g. sand, silica gel, acid binder, general purpose
binder, sawdust). 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. Protect against heat.
Protection against fire and explosion:
Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should
be kept handy.
Conditions for safe storage, including any incompatibilities
Suitable materials for containers: glass, Steel with polyethylene liner, stainless steel with
PTFE-coating, Isolemail PM Noir, special steel Hastelloy B3 2.4600, Proco-Enamel
Unsuitable materials for containers: carbon steel (iron), Stainless steel 1.4571, Stainless steel 1.4306
Further information on storage conditions: Keep container tightly closed in a cool, well-ventilated
place. Storage at a proportionate temperature is required, to avoid 'breathing' of containers.
Storage stability:
Storage temperature: 20 °C
Storage duration: 6 Months
From the data on storage duration in this safety data sheet no agreed statement regarding the
warrantee of application properties can be deduced.
Protect from temperatures above: 35 °C
The packed product must be protected against exceeding the indicated temperature.

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
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 (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
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray.

Chemical stability
The product is stable if stored and handled as prescribed/indicated.
Possibility of hazardous reactions
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. 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

chloromethane; methyl chloride, hydrogen chloride, Carbon dioxide

Disposal considerations

Waste treatment methods
Hydrolysis with alkali / ammonia solution in water.
Esterification with methanol and afterwards incineriation in a suitable incineration facility.
Contaminated packaging:
