First-aid measures
Description of first aid measures
Inhalation:
In case product dust is released:
Move victims into fresh air.
If symptoms persist, consult a physician for treatment.
Skin contact:
Wash off immediately with plenty of water.
If symptoms persist, consult a physician for treatment.
Eye contact:
Keeping eyelid open, immediately rinse thoroughly for at least 5 minutes using plenty of water or, if necessary, eye rinsing solution.
In case of persistent discomfort: Consult an ophthalmologist.
Ingestion:
Clean mouth with water and drink afterwards plenty of water.
After absorbing large amounts of substance / In case of discomfort: Supply with medical care.
Most important symptoms and effects, both acute and delayed
Symptoms:
Eye irritation
Hazards:
Harmful if swallowed.
Indication of any immediate medical attention and special treatment needed
If required, therapy of irritative effect.
Fire-fighting measures
Extinguishing media
Suitable extinguishing media:
Carbon dioxide (CO2)
dry powder
dry sand
Unsuitable extinguishing media:
Water
Special hazards arising from the substance or mixture:
Formation of carbon dioxide and carbon monoxide
Advice for firefighters:
Water for fire fighting must not be introduced in the sewer system, subsoil, or surface waters. Assure that there are sufficient fire water retaining facilities Contaminated fire fighting water must be disposed of in conformity with the regulations of the local authorities.
In the event of fire, wear self-contained breathing apparatus.
Employ protective equipment commonly used in the event of fire.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Wear personal protective equipment,
Keep away from sources of ignition - No smoking.
Avoid formation of dust. Ensure sufficient ventilation.
Environmental precautions
No special environmental precautions required.
Methods and material for containment and cleaning up
Immediate action:
Take up discharged product mechanically and gradually hydrolyze in portions in plenty of water. A five-fold volume of water should be added first. Dispose of wastes subsequently according to applicable regulations. Hydrolytic products: magnesium hydroxide (alkaline) and methanol (vapors are flammable).
Additional advice
Never return spills in original containers for re-use.
Handling and storage
Precautions for safe handling
Under inert gas (argon, nitrogen).
Avoid dust formation.
Keep away from water.
Conditions for safe storage, including any incompatibilities
Advice on protection against fire and explosion:
Normal measures for preventive fire protection.
Take precautionary measures against static charges, keep away from sources of ignition.
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:
Store in the original receptacle, keeping this tightly sealed, under cool and dry conditions.
Keep away from direct sunlight.
Protect from warming.
Advice on common storage:
Store away from: oxidizing agents.
Dust explosion class:

Maximum rate of pressure rise: 269,9 bar/s
ignition energy: 10 kJ
Standardized max. rate of pressure increase, KSt: 257,7bar·m/s

Exposure controls / personal protection
Control parameters:
hydrolysis product methanol
Control parameters
200 ppm
260 mg/m3
Indicative
Exposure controls
Engineering measures
Ensure suitable suction/aeration at the work place and with operational machinery.
Personal protective equipment
Respiratory protection
In case product dust is released:
Dust mask with P1 particle filter
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 0,5 mm
Break through time >= 480 min
The material thickness and rupture time data do not apply to non-solute solids / dusts.
Selection of protective gloves to meet the requirements of specific workplaces.
Suitability for specific workplaces should be clarified with protective glove manufacturers.
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
In case of dusts: Wear tight-fitting eye protection (e.g. safety goggles)
Skin and body protection
Flame retardant antistatic protective clothing.
Hygiene measures
Smoking, eating and drinking should be prohibited in the application area.
Wash face and/or hands before break and end of work.
Remove and wash contaminated clothing before re-use.
Apply adequate skin protection agents before handling the product. Assure skin cleaning and skin care after work. Preventive skin protection is recommended.
Protective measures
Handle in accordance with good industrial hygiene and safety practice.
The personal protective equipment used must meet the requirements of directive 89/686/EEC and amendments (CE certification).
It should be defined in the work place in the form of a risk analysis according to directive 89/686/EEC and amendments.
8.2. Exposure controls
Engineering measures
Ensure suitable suction/aeration at the work place and with operational machinery.

Disposal considerations
Waste treatment methods
Product
With respect to local regulations, e.g. dispose of to suitable waste incineration plant.
Other countries: observe the national regulations.
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.
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.
