Guidance on Safe Use

First-aid measures

Description of first aid measures

Take off all contaminated clothing immediately.

Inhalation:

In case product dust is released:

Possible discomfort: severe irritation of mucous lining (nose, throat, eyes), cough, sneezing, flow of tears

Move victims into fresh air.

If breathing difficulties occur:

Keep patient half sitting with upper body raised.

Call a physician immediately.

Skin contact:

Wash off immediately with plenty of water.

Consult a physician.

Eye contact:

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

Continue rinsing process with eye rinsing solution.

Protect unharmed eye.

Call ambulance. (Cue: caustic burn of the eyes)

Immediate further treatment in ophthalmic hospital/ ophthalmologist.

Continue rinsing eye until arrival at ophthalmic hospital.

Ingestion:

Do NOT induce vomiting.

Only when patient fully conscious:

Have the mouth rinsed with water.

Have patient drink plenty of water in small sips.

Notify ambulance immediately (keyword: chemical burn).

Most important symptoms and effects, both acute and delayed:

Symptoms

None known

Hazards

None known

Indication of any immediate medical attention and special treatment needed

Therapy as for chemical burn.

If substance has been swallowed:

Early endoscopy in order to assess mucosa lesions in the oesophagus and stomach which may appear.

If necessary, suck away leftover substance.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:       

water spray

Carbon dioxide (CO2)

Dry powder

Foam

Unsuitable extinguishing media:       High volume water jet

Special hazards arising from the substance or mixture

In the case of fire, the following hazardous smoke fumes may be produced: hydrogen chloride.

carbon monoxide, carbon dioxide

organic products of decomposition

Advice for firefighters

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

Ensure there are sufficient retaining facilities for water used to extinguish fire.

Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

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

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Use personal protective equipment.

Ensure adequate ventilation.

Avoid contact with the skin and the eyes.

Environmental precautions

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

Methods and material for containment and cleaning up

Pick up mechanically. Pour into containers which can be tightly sealed. Dispose of absorbed material in accordance with the regulations.

Use only non-sparking tools.

Handling and storage

Precautions for safe handling

Provide good ventilation or extraction.

In case of insufficient ventilation, wear suitable respiratory equipment.

Handle under inert gas

Do not use sparking tools.

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.

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.

Storage

Keep containers tightly closed in a cool, well-ventilated place.

Keep away from direct sunlight.

Protect from moisture.

Keep at temperatures of between 2 °C and 8 °C.

Under inert gas keep in a cool place.

Do not store together with: oxidizing agents

Exposure controls / personal protection

Engineering measures:

Ensure good ventilation during processing.

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 (filter type ABEK) or wear a self contained respiratory apparatus

Use only respiratory protection equipment with CE-symbol including four digit test number.

The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self-contained breathing apparatus must be used.

Note time limit for wearing respiratory protective equipment.

Hand protection:

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.

The material thickness and rupture time data do not apply to non-solute solids / dusts.

Eye protection:

close-fitting protective goggles (e.g. closed goggles) or face protection

Skin and body protection

When handling larger quantities:

One-way protective suit (dust-sealed)

Flame retardant antistatic protective clothing.

Hygiene measures:

When using, do not eat, drink or smoke. Wash face and/or hands before break and end of work.

Remove immediately all contaminated clothing.

Dispose of promptly.

Protective measures:

Handle in accordance with good industrial hygiene and safety practice.

The personal protective equipment used must meet the requirements of directive 89/686/EEC and amendments (CE certification).

If workplace exposure limits are exceeded and/or larger amounts are released (leakage, spilling, dust) the indicated respiratory protection should be used.

If there is the possibility of skin/eye contact, the indicated hand/eye/body protection should be used.

Use protective clothing / face shield if necessary.

Do not breathe vapours/dust.

Avoid contact with skin and eyes.

Stability and reactivity

Disposal considerations

Waste treatment methods

Product:

Confer with the producer.

Special treatment is necessary.

Uncleaned packaging:

Do not re-use empty containers.

Confer with the producer.

If there is product residue in the emptied container, follow directions for handling on the container's label.

Incorrect disposal or reuse of this container is illegal and can be dangerous.
