Guidance on Safe Use
Administrative data
First-aid measures
Description of first aid measures
Take off all contaminated clothing immediately.
Inhalation
If aerosol or mists are formed:
Move victims into fresh air.
In case of persistent discomfort: Consult doctor immediately.
Skin contact
Wash off immediately with plenty of water.
Consult a doctor in the event of permanent skin irritation.
Eye contact
With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.
Continue rinsing process with eye rinsing solution.
Protect unharmed eye.
Call ambulance. (Cue: caustic burn of the eyes)
Immediate further treatment in eye clinic/by eye doctor. continue rinsing eye until arrival at ophthalmic hospital.
Ingestion
Have the mouth rinsed with water.
Only when patient fully conscious:
Have patient drink plenty of water in small sips.
Consult a physician immediately.
Most important symptoms and effects, both acute and delayed
Symptoms
After absorbing large amounts of substance:
Liberation of reaction products (Methanol) can lead to symptoms of poisoning.
Possible signs of poisoning:
daze, dizziness, nausea, colicky abdominal pain, respiratory disturbance.
Symptoms upon increasing intoxication: dysopia, loss of eyesight.
Indication of any immediate medical attention and special treatment needed
If required, therapy of irritative effect.
Treatment:
Early endoscopy in order to assess mucosa lesions in the oesophagus and stomach which may appear. If necessary, aspirate leftover substance.
Detection of substance (Methanol) possible in:
Blood
Antidote treatment: ethanol.
Fire-fighting measures
Suitable extinguishing media
foam, water spray, CO2, dry powder
Special hazards arising from the substance or mixture
Hazardous fumes in fires, specific to the product:
nitrogen oxides (NOx)
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
Use personal protective equipment.
Environmental precautions
Do not allow entrance in sewage water, soil stretches of water, groundwater, drainage systems.
Methods and material for containment and cleaning up
Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).
Transfer into suitable containers.
To be disposed of in compliance with existing regulations.
Suitable binder: sand (for damming up), sawdust
Handling and storage
Handling
Precautions for safe handling
Application, processing: Provide good ventilation or extraction.
Advice on protection against fire and explosion
Keep away from sources of ignition - No smoking.
Storage
Conditions for safe storage, including any incompatibilities
Keep containers tightly closed in a cool, well-ventilated place.
Protect from moisture.

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 ABEK) 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
Glove material for example, Fluorinated rubber (Viton)
Material thickness 0,4 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)
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.
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.
Use protective clothing / face shield if necessary.
Do not breathe in vapours or aerosols.
Avoid contact with skin and eyes.
Stability and reactivity
Possibility of hazardous reactions
Exothermic reaction with: acids
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
