Most important symptoms and effects, both acute and delayed
Symptoms
None known
Hazards
None known
Indication of any immediate medical attention and special treatment needed
If substance has been swallowed:
Gastric lavage, administration of activated charcoal, acceleration of gastrointestinal passage.

Fire-fighting measures

Suitable extinguishing media
foam, water spray, CO2, dry powder
Special hazards arising from the substance or mixture
Closed container may rupture if strongly heated.
In case of fire cool endangered containers with water.
Special protective equipment for fire-fighters
In case of fire: wear a self contained respiratory apparatus
Advice for firefighters
Water used to extinguish fire should not enter drainage systems, soil or stretches of water.
Ensure there are sufficient retaining facilities for water used to extinguish fire.
Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Wear personal protective equipment; see section 8.
Keep out unprotected persons.
Do not inhale vapours / aerosols.
Leave room immediately.
Alert all persons!
Keep away from sources of ignition - No smoking.
Environmental precautions
Do not allow entrance in sewage water, soil stretches of water, groundwater, drainage systems.
Should not be released into the environment.
Cover over drainage system. Avoid penetration into drainage system or in rooms situated at a lower level because of danger of explosion.
Methods and material for containment and cleaning up
Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).
Fill into marked, sealable containers.
To be disposed of in compliance with existing regulations.
Suitable binder: diatomaceous earth, universal absorbent

Handling and storage

Handling
Precautions for safe handling
Open the containers with caution.
If possible, use material transfer/filling, metering and blending plants that are closed, or provide for local suction devices.
Advice on protection against fire and explosion
Take precautionary measures against static discharges.
Keep away from sources of ignition - No smoking.
Explosion protection equipment required.
When repairs of the production system are to be made (e.g. welding work), the section to be repaired must be essentially free of product.
Storage
Conditions for safe storage, including any incompatibilities
Keep containers tightly closed in a cool, well-ventilated place.
Protect from moisture.
Comply with storage regulations and regulations prohibiting storage of hazardous substances in non-stationary containers in the same room (TRGS 510).

Exposure controls / personal protection

Control parameters

Engineering measures
If possible, use material transfer/filling, metering and blending plants that are closed, or provide for local suction devices.
Priority should be given to closed-system units.
Personal protective equipment
Respiratory protection
In case of dusts/vapours/aerosols being formed or if the limit values like TLV are exceeded:
use respiratory equipment with suitable filter (filter type A) or wear a self contained respiratory apparatus
Use only respiratory protection equipment with CE-symbol including four digit test number.
The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self-contained breathing apparatus must be used.
Note time limit for wearing respiratory protective equipment.
Hand protection
Glove material for example, butyl-rubber
Material thickness 0,5 mm
Break through time >= 480 min
Selection of protective gloves to meet the requirements of specific workplaces.
Suitability for specific workplaces should be clarified with protective glove manufacturers.
The information is based on our own tests, references from the literature and information from glove manufacturers, or derived by analogy with similar materials.
Please observe that the daily duration of usage of a chemical protective glove is in practice far shorter due to the many influencing factors (e.g. temperature, mechanical strain on the glove material) than the permeation time determined acc. EN 374.
Eye protection
close-fitting protective goggles (e.g. closed goggles)
Skin and body protection
When handling larger quantities:
Wear protective clothing made from non-flammable fibres.
Hygiene measures
When using, do not eat, drink or smoke. Wash face and/or hands before break and end of work.
Remove immediately all contaminated clothing.
Wash contaminated clothing before re-use.
Protective measures
Handle in accordance with good industrial hygiene and safety practices.
It should be defined in the work place in the form of a risk analysis according to directive 89/686/EEC and amendments.
If workplace exposure limits are exceeded and/or larger amounts are released (leakage, spilling, dust) the indicated respiratory protection should be used.
If there is the possibility of skin/eye contact, the indicated hand/eye/body protection should be used.
Do not breathe in vapours or aerosols.
Avoid contact with skin and eyes.

Stability and reactivity

Incompatible materials
Exothermic reaction with:, acids, alkalines, Incompatibility with, humidity, water

Hazardous decomposition products
Methanol in case of hydrolysis.

Disposal considerations

Product
With respect to local regulations, e.g. dispose of to suitable waste incineration plant.
Uncleaned packaging
Do not reuse empty containers and dispose of in accordance with the regulations issued by the appropriate local authorities.
If there is product residue in the emptied container, follow directions for handling on the container's label.
Incorrect disposal or reuse of this container is illegal and can be dangerous.
Other countries: observe the national regulations.
Waste Key Number
No waste key number as per the European Waste Types List can be assigned to this product, since such classification is based on the (as yet undetermined) use to which the product is put by the consumer.
The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.
