Guidance on Safe Use

First-aid measures

Eye contact:

Get medical attention immediately. Call a poison center or physician. Immediately

flush eyes with plenty of water, occasionally lifting the upper and lower eyelids.

Check for and remove any contact lenses. Continue to rinse for at least 10 minutes.

Inhalation:

Remove patient to fresh air and keep at rest in a position comfortable for breathing.

Loosen tight clothing such as a collar, tie, belt or waistband. Consult a physician

immediately if symptoms such as shortness of breath or asthma are observed.

Skin contact:

Wash with plenty of soap and water. Remove contaminated clothing and shoes.

Continue to rinse for at least 10 minutes. Get medical attention if symptoms appear.

Ingestion:

Wash out mouth with water. Remove dentures if any. Remove patient to fresh air

and keep at rest in a position comfortable for breathing. If material has been

swallowed and the exposed person is conscious, give small quantities of water to

drink. Do not induce vomiting unless directed to do so by medical personnel.

Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention if

symptoms appear.

Protection of first-aiders:

No action shall be taken involving any personal risk or without suitable training. If it

is suspected that fumes are still present, the rescuer should wear an appropriate

mask or self-contained breathing apparatus. It may be dangerous to the person

providing aid to give mouth-to-mouth resuscitation. Wash contaminated clothing

thoroughly with water before removing it, or wear gloves.

Fire-fighting measures

Extinguishing media

- Suitable extinguishing media:

Use dry chemical powder. Waterspray.

- Unsuitable extinguishing media:

Do not use water jet.

Special hazards arising from the substance or mixture

- Hazards from the substance or mixture:

Fine dust clouds may form explosive mixtures with air.

-Hazardous thermal decomposition products:

Carbon, nitrogen and sulfur oxides

Advice for firefighters

- Special precautions for fire-fighters:

Promptly isolate the scene by removing all persons from the vicinity of the incident if

there is a fire. No action shall be taken involving any personal risk or without

suitable training. Move containers from fire area if this can be done without risk.

Use water spray to keep fire-exposed containers cool.

- Special protective equipment for fire-fighters:

Fire-fighters should wear appropriate protective equipment and self-contained

breathing apparatus (SCBA) with a full face-piece operated in positive pressure

mode. Clothing for fire-fighters (including helmets, protective boots and gloves)

conforming to European standard EN 469 will provide a basic level of protection for

chemical incidents.

Not explosive

Accidental release measures

Personal precautions, protective equipment and emergency procedures

- For non-emergency personnel:

No action shall be taken involving any personal risk or without suitable training.

Evacuate surrounding areas. Keep unnecessary and unprotected personnel from

entering. Do not touch or walk through spilt material. Shut off all ignition sources.

No flares, smoking or flames in hazard area. Do not breathe dust. Provide

adequate ventilation. Wear appropriate respirator when ventilation is inadequate.

Put on appropriate personal protective equipment.

- For emergency responders:

If specialised clothing is required to deal with the spillage, take note of any on suitable and unsuitable materials.

See also the

information in "For non-emergency personnel".

Environmental precautions

Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains

and sewers. Inform the relevant authorities if the product has caused environmental

pollution (sewers, waterways, soil or air).

Methods and material for containment and cleaning up

- Small spill:

Move containers from spill area. Avoid dust generation. Using a vacuum with

HEPA filter will reduce dust dispersal. Place spilled material in a designated,

labeled waste container. Dispose of via a licensed waste disposal contractor.

- Large spill:

Move containers from spill area. Approach the release from upwind. Prevent entry

into sewers, water courses, basements or confined areas. Avoid dust generation.

Do not dry sweep. Vacuum dust with equipment fitted with a HEPA filter and place

in a closed, labeled waste container. Avoid creating dusty conditions and prevent

wind dispersal. Dispose of via a licensed waste disposal contractor.

Handling and storage

Precautions for safe handling

- Protective measures:

Put on appropriate personal protective equipment. Persons with a

history of skin sensitization problems should not be employed in any process in

which this product is used. Do not get in eyes or on skin or clothing. Do not breathe

dust. Do not ingest. Avoid the creation of dust when handling and avoid all possible

sources of ignition (spark or flame). Prevent dust accumulation. Use only with

adequate ventilation. Wear appropriate respirator when ventilation is inadequate.

Keep in the original container or an approved alternative made from a compatible

material, kept tightly closed when not in use. Take precautionary measures against

electrostatic discharges. Empty containers retain product residue and can be

hazardous. Do not reuse container.

- Advice on general occupational hygiene:

Eating, drinking and smoking should be prohibited in areas where this material is

handled, stored and processed. Workers should wash hands and face before

eating, drinking and smoking. Remove contaminated clothing and protective

equipment before entering eating areas.

Conditions for safe storage, including any incompatibilities

Store in accordance with local regulations. Store in a segregated and approved area. Store in original container protected from direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials and food and drink. Store locked up. Eliminate all ignition sources. Separate from oxidizing materials. Keep container tightly closed and sealed until ready for use.

Containers that have been opened must be carefully resealed and kept upright to prevent

leakage. Do not store in unlabelled containers. Use appropriate containment to avoid environmental contamination.

Exposure controls / personal protection

- Hygiene measures:

Avoid ingestion, inhalation, skin and eye contact. Handle in accordance with good

industrial hygiene practice and any legal requirements. Wash hands, forearms and

face thoroughly after handling chemical products, before eating, smoking and using

the lavatory and at the end of the working period. Contaminated work clothing

should not be allowed out of the workplace. Wash contaminated clothing before

reusing. Ensure that eyewash stations and safety showers are close to the

workstation location.

- Eye/face protection:

Safety eyewear complying with an approved standard should be used when a risk

assessment indicates this is necessary to avoid exposure to liquid splashes, mists,

gases or dusts. If contact is possible, the following protection should be worn,

unless the assessment indicates a higher degree of protection: If inhalation

hazards exist, a full-face respirator may be required instead. Recommended:

tightly fitting safety goggles

- Skin protection:

Hand protection:

Chemical-resistant, impervious gloves complying with an approved standard should

be worn at all times when handling chemical products if a risk assessment indicates

this is necessary. < 1 hour (breakthrough time): butyl or neoprene.

Use gloves approved to relevant standards e.g. EN 374 (Europe), F739 (US).

Suitability and durability of a glove is dependent on usage, e.g. frequency and

duration of contact, chemical resistance of glove material and dexterity. Always

seek advice from glove suppliers. Additional information can be found for instance

at www.gisbau.de.
