TYPES OF HAZARD
|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE-FIGHTING|
|FIRE||Highly flammable.||NO open flames, NO sparks and NO smoking.||Use alcohol-resistant foam, foam, powder, carbon dioxide, fine water spray.|
|EXPLOSION||Vapour/air mixtures are explosive. Heating will cause rise in pressure with risk of bursting.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.||In case of fire: keep drums, etc., cool by spraying with water.|
|EXPOSURE||AVOID ALL CONTACT!|
|Inhalation||Sore throat. Cough. Shortness of breath.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer for medical attention.|
|Skin||Redness. Dry skin.||Protective gloves.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell.|
|Eyes||Redness.||Wear safety goggles or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Do not eat, drink, or smoke during work.||Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .|
|PACKAGING & LABELLING|
|Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.||
