First-aid measures

Description of first aid measures
General information:
Take persons to a safe place. Observe self-protection for first aid.
After contact with the eyes:
Rinse immediately with plenty of water for 10-15 minutes. Seek medical advice in case of continuous irritation.
After contact with the skin:
Remove contaminated or soaked clothing. Immediately rinse with plenty of soap and water. In the event of a visible skin change
or other complaints, seek medical advice (show label or SDS where possible).
After inhalation:
Keep the patient calm. If unconscious place in stable sideways position. Protect against loss of body heat. In cases of sickness
seek medical advice (show label or SDS if possible).
After swallowing:
If conscious, give several small portions of water to drink. Do not induce vomiting. Seek medical advice immediately and clearly
identify substance.

Most important symptoms and effects, both acute and delayed
Any relevant information can be found in other parts of this section.

Indication of any immediate medical attention and special treatment needed
Methanol (CAS 67-56-1) is readily and rapidly absorbed at all exposure routes and is toxic by all routes. Methanol may cause
irritation of the mucosa, as well as nausea, vomiting, headaches, vertigo and visual disorders, including blindness (irreversible
damage to the optic nerve), acidosis, spasms, narcosis and coma. There may be a delay in the onset of these effects after

Fire-fighting measures

Extinguishing media
Suitable extinguishing media:
water mist , extinguishing powder , alcohol-resistant foam , carbon dioxide , sand .
Extinguishing media which must not be used for safety reasons:
water jet .

Special hazards arising from the substance or mixture
Risk of hazardous gasses or fumes in the event of fire. Exposure to combustion products may be a health hazard! Hazardous
combustion products: carbon oxides , silicon oxides , incompletely burnt hydrocarbons , toxic and very toxic fumes .

Advice for firefighters
Special protective equipment for fire fighting:
Use respiratory protection independent of recirculated air. Keep unprotected persons away.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Secure the area. Wear personal protection equipment (see section Exposure controls/personal protection).
Keep unprotected persons away. Avoid contact with eyes
and skin. Do not inhale gases/vapours/aerosols. If material is released indicate risk of slipping. Do not walk through spilled

Environmental precautions
Prevent material from entering surface waters, drains or sewers and soil. Close leak if possible without risk. Contain any fluid that
runs out using suitable material (e.g. earth). Retain contaminated water/extinguishing water. Dispose of in prescribed marked
containers. Inform authorities if substance leaks into surface waters, sewerage or ground.

Methods and material for containment and cleaning up
Take up mechanically and dispose of according to local/state/federal regulations. Do not flush away with water. For small
amounts: Absorb with a neutral (non-acidic / non-basic) liquid binding material such as diatomaceous earth and dispose of
according to government regulations. For large amounts: Liquids may be recovered using suction devices or pumps. If flammable,
only air driven or properly rated electrical equipment should be used. Clean any slippery coating that remains using a detergent /
soap solution or another biodegradable cleaner. Silicone fluids are slippery; spills are a safety hazard. Apply sand or other inert
granular material to improve traction.
Further information:
Exhaust vapours. Eliminate all sources of ignition. Consider explosion protection. Observe notes under section Handling and storage.

Reference to other sections
Relevant information in other sections has to be considered. This applies in particular for information given on personal protective
equipment (section Exposure controls/personal protection) and on disposal (section Disposal considerations).

Handling and storage

Precautions for safe handling:
Ensure adequate ventilation. Must be syphoned off in situ. Spilled substance increases risk of slipping. Avoid formation of
aerosols. In case of aerosol formation special protective measures are required (exhausting by suction, respiratory protection).
Observe information in section Exposure controls/personal protection. Keep away from incompatible substances in accordance with section Stability and reactivity.

Exposure controls / personal protection

Control parameters
Maximum airborne concentrations at the workplace:
CAS No. Material Type mg/m3 ppm Dust fract. Fibre/m3
67-56-1 Methanol AGW 270,0 200,0
Methanol (CAS no. 67-56-1): Refer to Technical Rules for Hazardous Substances "TRGS 900" for more details on the German AGW.

Exposure controls
Exposure in the work place limited and controlled
General protection and hygiene measures:
Avoid contact with eyes and skin. Do not inhale gases/vapours/aerosols. Do not eat, drink or smoke when handling.
Personal protection equipment:
Respiratory protection
In case of long or strong exposure: gas mask filter ABEK .
Eye protection
tight fitting protective goggles .
Hand protection
Protective gloves made of butyl rubber . Gloves suitable for up to 60 minutes' use. The selection of appropriate gloves not only
depends on the material, but also on other quality characteristics, and may vary depending on the manufacturer. Please observe
information from your glove supplier in terms of permeability and breakthrough time.
Skin protection
protective clothing .

Exposure to the environment limited and controlled
Prevent material from entering surface waters, drains or sewers and soil. Do not introduce large amounts into purification plants.

Further information for system design and engineering measures
Observe information in section Handling and storage.

Stability and reactivity

If stored and handled in accordance with standard industrial practices no hazardous reactions are known.
Relevant information can possibly be found in other parts of this section.

Conditions to avoid

Incompatible materials
Reacts with: water , basic substances and acids . Reaction causes the formation of: methanol .

Disposal considerations

Waste treatment methods
Material that cannot be used, reprocessed or recycled should be disposed of in accordance with Federal, State, and local
regulations at an approved facility. Depending on the regulations, waste treatment methods may include, e.g., landfill or
Uncleaned packaging
Completely discharge containers (no tear drops, no powder rest, scraped carefully). Containers may be recycled or re-used.
Observe local/state/federal regulations. Uncleaned packaging should be treated with the same precautions as the material.
Waste Disposal Legislation Ref.No.(EC)
It is not possible to determine a waste code for this product in accordance with the European Waste Catalogue (EWC) since it is
only possible to classify it according to how it is used by the customer. The waste code is to be determined within the EU in liaison
with the waste-disposal operator.
