TYPES OF HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE | Flammable. | NO open flames, NO sparks and NO smoking. | Use powder, alcohol-resistant foam, water spray, carbon dioxide. |
| EXPLOSION | Above 39°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong oxidants. | Above 39°C use a closed system, ventilation and explosion-proof electrical equipment. | In case of fire: keep drums, etc., cool by spraying with water. |
| EXPOSURE | AVOID ALL CONTACT! | ||
| Inhalation | Sore throat. Cough. Burning sensation. Headache. Dizziness. Shortness of breath. Laboured breathing. | Use ventilation, local exhaust or breathing protection. | Fresh air, rest. Half-upright position. Refer immediately for medical attention. |
| Skin | Pain. Redness. Skin burns. Blisters. | Protective gloves. Protective clothing. | Remove contaminated clothes. Rinse and then wash skin with water and soap. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention. |
| Eyes | Redness. Pain. Severe burns. Loss of vision. | Wear face shield or eye protection in combination with breathing protection. | Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention. |
| Ingestion | Sore throat. Burning sensation. Abdominal pain. Vomiting. Shock or collapse. | Do not eat, drink, or smoke during work. | Rinse mouth. Do NOT induce vomiting. If within a few minutes after ingestion, one small glass of water may be given to drink. Refer immediately for medical attention. |
