Inhalation: Get medical attention immediately. Move exposed person to fresh

air. If it is suspected that fumes are still present, the rescuer

should wear an appropriate mask or self-contained breathing

apparatus. Keep person warm and at rest. If not breathing, if

breathing is irregular or if respiratory arrest occurs, provide artificial

respiration or oxygen by trained personnel. It may be dangerous to

the person providing aid to give mouth-to-mouth resuscitation. If

unconscious, place in recovery position and get medical attention

immediately. Maintain an open airway. Loosen tight clothing such

as a collar, tie, belt or waistband. In case of inhalation of decomposition products in a fire, symptoms may be delayed. The

exposed person may need to be kept under medical surveillance for 48 hours.

Ingestion: Get medical attention immediately. Wash out mouth with water.

Move exposed person to fresh air. Keep person warm and at rest.

If material has been swallowed and the exposed person is

conscious, give small quantities of water to drink. Stop if the

exposed person feels sick as vomiting may be dangerous. Do not

induce vomiting unless directed to do so by medical personnel. If

vomiting occurs, the head should be kept low so that vomit does

not enter the lungs. Chemical burns must be treated promptly by a

physician. Never give anything by mouth to an unconscious

person. If unconscious, place in recovery position and get medical

attention immediately. Maintain an open airway. Loosen tight

clothing such as a collar, tie, belt or waistband.

Skin contact: Get medical attention immediately. Wash skin immediately with

plenty of water and soap. Remove contaminated clothing and

shoes. Continue to rinse for at least 10 minutes. Chemical burns

must be treated promptly by a physician. Wash clothing before

reuse. Clean shoes thoroughly before reuse.

waterways, drains and sewers. Inform the relevant authorities if

the product has caused environmental pollution (sewers, waterways, soil or air).

Methods and materials for containment and cleaning up

Small spill: Move containers from spill area. Vacuum or sweep up material and

place in a designated, labelled waste container. Use spark-proof

tools and explosion-proof equipment. Dispose of via a licensed waste disposal contractor.

Large spill: Move containers from spill area. Prevent entry into sewers, water

courses, basements or confined areas. Vacuum or sweep up

material and place in a designated, labelled waste container. Avoid

creating dusty conditions and prevent wind dispersal. Use sparkproof

tools and explosion-proof equipment. Dispose of via a licensed waste disposal contractor.

Handling and storage

Precautions for safe handling: Avoid exposure - obtain special instructions before use. Put on

appropriate personal protective equipment). 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. Avoid

exposure during pregnancy. 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. Electrical equipment and lighting should be

protected to appropriate standards to prevent dust coming into

contact with hot surfaces, sparks or other ignition sources. Empty

containers retain product residue and can be hazardous. The

product is registered with strictly controlled conditions

and must therefore be handled as such. Refer to the

industry guidance prepared by Concawe/Cefic/EFCG for advice on the confirmation of strictly controlled conditions.

Conditions for safe storage, including any incompatibilities

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.

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.

Remarks: Keep under nitrogen or argon. Take precautionary measures

against electrostatic discharges. Avoid all possible sources of

ignition (spark or flame). Vent waste air only via suitable separators or scrubbers.
