TYPES OF HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE | Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. | In case of fire in the surroundings, use appropriate extinguishing media. | |
| EXPLOSION | In case of fire: keep drums, etc., cool by spraying with water. | ||
| EXPOSURE | STRICT HYGIENE! | IN ALL CASES CONSULT A DOCTOR! | |
| Inhalation | Cough. Sore throat. Nausea. Vomiting. Diarrhoea. Headache. Dizziness. Drowsiness. Weakness. Convulsions. Confusion. Death Symptoms may be delayed. See Notes. | Use ventilation, local exhaust or breathing protection. | Fresh air, rest. Refer immediately for medical attention. |
| Skin | Redness. Pain. | Protective gloves. Protective clothing. | Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . |
| Eyes | Redness. Pain. | 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 | See Inhalation. | Do not eat, drink, or smoke during work. | Rinse mouth. Do NOT induce vomiting. Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention. |

The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. |
| NOTES |
| The symptoms of acute poisoning do not become manifest until hours or even days after exposure, and they are aggravated by physical effort. |
