Sodium 2-methylbutan-2-olate

Guidance on Safe Use

First-aid measures

Description of first aid measures

Pay attention to self-protection.

Remove victims from hazardous area. Immediately remove soiled or soaked clothing and remove it to a safe distance. Keep victim warm, in a stabilized position and covered.

Do not leave victims unattended.

If the casualty is unconscious: Place the victim in the recovery position.

Inhalation

Potential for exposure by inhalation if dusts or smoke are generated.

Move victims into fresh air.

With labored breathing: Provide with oxygen. Consult a doctor.

If the casualty is not breathing: Perform mouth-to-mouth resuscitation, notify emergency physician immediately.

Skin contact

Wash off affected area immediately with plenty of water for at least 15 minutes.

If symptoms persist, consult a physician for treatment.

Eye contact

With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.

Consult an ophthalmologist immediately if the symptoms persist.

When dealing with caustic substances, notify emergency physician immediately (key words: burns in eye).

Ingestion

Rinse mouth.

Immediately give large quantities of water to drink.

Obtain medical attention.

When dealing with caustic substances, notify emergency physician immediately.

Most important symptoms and effects, both acute and delayed

Symptoms

Irritation of skin and mucous membranes

Causes burns.

daze,

Headache, vertigo, somnolence (sleepiness), nausea.

Health injuries may be delayed.

Hazards

Strongly irritating to corrosive.Harmful in contact with skin and if swallowed.                                                                               .Vapours may cause drowsiness and dizziness

Indication of any immediate medical attention and special treatment needed

The initial focus is only on the local action, possibly characterized by a progressive tissue irritation; caustic substances result in quickly progressing deep

tissue damage.

In the eye, caustic dusts or smoke cause, depending on the intensity of exposure, severe irritation, destruction, and ablation of the epithelium of the

conjunctiva and cornea, corneal clouding, edema and ulcerations.

Danger! Possible loss of eyesight!

Superficial irritations and damage up to ulcerations and scarring develop on the skin.

After accidental absorption in the body, the pathology and clinical findings are dependent on the kinetics of the substance (quantity of absorbed substance,

the absorption time, and the effectiveness of early elimination measures (first aid)/ excretion - metabolism).

A specific action of the substance is unknown.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:       dry sand, dry powder, alcohol stable extinguishing foam

Unsuitable extinguishing media: water, foam, Halons, Carbon dioxide (CO2), Do not use full-force water jet in order to avoid dispersal and spread of the fire

Special hazards arising from the substance or mixture

Reacts violently with water and foam.

In the case of fire, the following hazardous smoke fumes may be produced: carbon monoxide, carbon dioxide.

organic products of decompositionIn case of fire-fighting with water or foam be aware of dangers of corrosion and of slipping.

Combustion residues must be disposed of properly.

Advice for firefighters

Contaminated extinguishing water must be treated at a suitable disposal plant in accordance with waste management laws.

Water used to extinguish fire should not enter drainage systems, soil or stretches of water.

In case of fire, remove the endangered containers and bring to a safe place, if this can be done safely.

Use water spray to cool unopened containers.

Fire residues should be disposed of in accordance with the regulations.

Pay attention to self-protection.

Keep out unprotected persons.

In case of fire: full protective suit and wear a self contained respiratory apparatus

Accidental release measures

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Avoid dust formation.

Keep away from sources of ignition - No smoking.

Suitable binder: dry sand

Reference to other sections

Wear personal protective equipment.

Handling and storage

Precautions for safe handling

Decant and handle product in separate areas only, e.g. use glove boxes, cabinets with differential pressure switch etc.

Ensure that apparatus and pipelines are free from leaks. Do not ventilate into the open.

Dedicated loading/unloading stations required.

Conditions for safe storage, including any incompatibilities

Advice on protection against fire and explosion

Take precautionary measures against static discharges.

Keep away from sources of ignition - No smoking.

No sparking tools should be used.

Avoid dust formation.

If dusts develop, explosive dust/air mixtures may form.

Storage

Store in the original receptacle, keeping this tightly sealed, under cool and dry conditions.

Protect from warming.

Avoid humidity and water.

Storage under inert gas (nitrogen) recommended.

Suitable materials: polyethylene

Unsuitable materials: light metals and their alloys, Aluminium, Zinc

Further information

In order to ensure due transportation, make certain that stacks are of the correct height, containers are securely fastened so as not to fall off, and labelled

according to the regulations.
