Guidance on Safe Use

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

exposure.

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

material.

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.

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

Disposal considerations

Waste treatment methods

Material

Recommendation:

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

incineration.

Uncleaned packaging

Recommendation:

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.
