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

Treatment:

Immediate gastric lavage. Antidote treatment, correction of acid-base balance.

Detection of substance (Methanol) possible in:

Blood

Antidote treatment: ethanol.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

Water spray, foam, CO2, dry powder.

Unsuitable extinguishing media:

Do not use a solid water stream as it may scatter and spread fire.

Special hazards arising from the substance or mixture

May be released in case of fire: toxic gases/vapours.

Closed container may rupture if strongly heated..

Advice for firefighters

Use water spray to cool unopened containers.

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 case of fire, wear respiratory protective equipment independent of surrounding air and chemical

protective suit.

Employ protective equipment commonly used in the event of fire.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Wear personal protective equipment.

Environmental precautions

Do not allow entrance in drainage systems, sewage water, groundwater or soil.

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:

sand (for damming up), sawdust, universal absorbent

Handling and storage

Precautions for safe handling

Provide sufficient ventilation and exhaust at the workplace.

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.

Use only non-sparking tools.

Use explosion-proof equipment.

Storage

Store in a well-ventilated place. Keep container tightly closed.

Avoid heat effect and sources of ignition.

Advice on common storage

Store separately from oxidants

German storage class

3 - Flammable liquids

Exposure controls

Engineering measures

Ensure suitable suction/aeration at the work place and with operational machinery.

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 or wear a self contained respiratory apparatus

Hand protection

Wear protective gloves made of the following materials:.

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.

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) or face protection

Skin and body protection

Wear suitable 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.

Apply adequate skin protection agents before handling the product. Assure skin cleaning and skin care

after work. Preventive skin protection is recommended.

Protective measures

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.

Handle in accordance with good industrial hygiene and safety practices.

Stability and reactivity

Reactivity

Vapours may form explosive mixture with air.

Chemical stability

Stable under recommended storage conditions.

Conditions to avoid

Keep away from heat and sources of ignition.

Incompatible materials

Water, oxidizing agents
