_____________________________________________________________________________________________ Avoid release to the environment. Local authorities should be advised if significant spillages cannot be contained. 6.3 Methods and material for containment and cleaning up Methods for containment Prevent further leakage or spillage if safe to do so. Cover powder spill with plastic sheet or tarp to minimize spreading. Methods for cleaning up Avoid dust formation. Do not dry sweep dust. Wet dust with water before sweeping or use a vacuum to collect dust. Take precautionary measures against static discharges. Use non-sparking tools and equipment. Material becomes slippery when wet. Use caution if wet. After cleaning, flush away traces with water. 6.4 Reference to other sections See section 13 for more information.

7. Handling and storage 7.1 Precautions for safe handling Handling Handle in accordance with good industrial hygiene and safety practice. Avoid contact with skin and eyes. Avoid handling causing generation of dust. Material becomes slippery when wet. Use caution if wet. Avoid breathing dust; if exposed to high dust concentration, leave area immediately. Fine dust dispersed in air may ignite. Take precautionary measures against static discharges. Hygiene measures Use good work and personal hygiene practices to avoid exposure. Do not eat, drink or smoke when using this product. Wash hands and face before breaks and immediately after handling the product. 7.2 Conditions for safe storage, including any incompatibilities Technical measures/precautions

Ensure adequate ventilation. Provide appropriate exhaust ventilation at places where dust is formed. Keep airborne concentrations below exposure limits.

Storage precautions

Keep away from open flames, hot surfaces and sources of ignition. Keep containers tightly closed in a dry, cool and well-ventilated place.

8. Exposure controls/personal protection 8.1 Control parameters Exposure limits

Component Carbohydrate polymer ( 60-100 )

Control as an ACGIH particulate not otherwise specified (PNOS): 10 mg/m3 (Inhalable); 3 mg/m3 (Respirable) and an OSHA particulate not otherwise regulated (PNOR): 15 mg/m3 (Total); 5 mg/m3 (Respirable).

ACGIH TLV Not determined

OSHA PEL Not determined

8.2 Exposure controls A risk assessment is recommended to be performed by a qualified and trained personnel to analyze the worksite and recommends the appropriate controls such as engineering controls, work practice controls, and administrative controls as primary means of reducing employee exposure. When there is a remaining hazards after applying the primary controls, Personal Protective Equipment (PPE) must be used.
