First-aid measures

4.1 Description of first aid measures

General advice:

Seek medical advice in case of symptoms caused by eye or skin contact, inhalation or swallowing. Remove contaminated or soaked clothing immediately and dispose of safely.

If inhaled:

Move to fresh air.

In case of skin contact:

Before washing use a dry brush to remove dust from skin.

Wash off with plenty of water and soap immediately.

In case of eye contact:

Rinse immediately with plenty of water, also under the eyelids, for at least 10 minutes.

Remove contact lenses if this can be easily done.

Immediate further treatment in ophthalmic hospital/ ophthalmologist.

If swallowed:

Rinse out mouth.

Drink 1 or 2 glasses of water.

Do NOT induce vomiting.

4.2 Most important symptoms and effects, both acute and delayed

Symptoms:

Nausea

Vomiting

Irritation of skin and mucous membranes

Risks:

In contact with aqueous liquids, the product hydrolyses to flammable gases and strong alcaline hydroxide.

4.3 Indication of any immediate medical attention and special treatment needed

Treatment:

Do NOT induce vomiting. In case of the intake of large amounts, pump out stomach ensuring to avoid reinhalation. In case of skin irritation, use corticoid containing external preparations.

5.3 Advice for firefighters

Special protective equipment for firefighters:

In the case of fire, wear respiratory protective equipment in-dependent of surrounding air and chemical protective suit.

Further information:

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

Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Personal precautions:

Wear personal protective equipment; see section 8.

Keep out unprotected persons.

Avoid all contact with water and moisture.

Keep away from sources of ignition - No smoking.

6.2 Environmental precautions

Environmental precautions:

Do not allow substance to enter soil, bodies of water or sew-age canals.

6.3 Methods and material for containment and cleaning up

Methods for cleaning up:

Pick up mechanically and collect in a suitable container. Avoid formation of dust.

Keep containers open; do not seal hermetically.

Keep away from water and humidity.

6.4 Reference to other sections

For disposal considerations see section 13.

Handling and storage

7.1 Precautions for safe handling

Advice on safe handling:

Provide sufficient ventilation and exhaust at the workplace.

Avoid dust formation.

Avoid deposition of dust.

Protect against humid air and water.

Handle and open container with care.

Advice on protection against fire and explosion:

Contact with water liberates extremely flammable gases. Protect against humid air and water. Keep away from combustion sources such as sparks, flames and unprotected light sources Use only explosion-proof equipment. No sparking tools should be used.

Hygiene measures:

Do not breathe vapors/dust. Contact with skin, eyes and clothes must be strictly avoided Remove contaminated or saturated clothing immediately and dispose of safely. Before reuse remove dust in a dry manner, then wash. Keep working clothes separately. Do not eat, drink or smoke while working. Wash hands, and/or face before breaks and when workday is finished. Keep away from food, drink and animal feeding stuffs.

7.2 Conditions for safe storage, including any incompatibilities

Requirements for storage areas and containers:

Store in a dry place. Protect from moisture. recommended: cover with dry inert gas.

Advice on common storage:

Incompatible with acids and bases.

Incompatible with oxidizing agents.

Never allow product to get in contact with water during storage.

Packaging material:

Suitable material: Mild steel, Aluminum
