ACUTE HAZARDS | PREVENTION | FIRE FIGHTING | |
---|---|---|---|
FIRE & EXPLOSION | Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive. Risk of fire and explosion on contact with oxidants. | NO open flames, NO sparks and NO smoking. NO contact with oxidizing agents or acids. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. | Use powder, alcohol-resistant foam, water in large amounts, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. |
AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! | |||
---|---|---|---|
SYMPTOMS | PREVENTION | FIRST AID | |
Inhalation | Cough. Sore throat. Burning sensation. Nausea. Headache. Vomiting. Laboured breathing. Convulsions. | Use ventilation, local exhaust or breathing protection. | Fresh air, rest. Half-upright position. Refer immediately for medical attention. |
Skin | MAY BE ABSORBED! Redness. Pain. Further see Inhalation. | Protective gloves. Protective clothing. | First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . |
Eyes | Redness. Pain. | Wear face shield or eye protection in combination with breathing protection. | Rinse with plenty of water (remove contact lenses if easily possible). |
Ingestion | Sore throat. Further see Inhalation. | Do not eat, drink, or smoke during work. Wash hands before eating. | Rinse mouth. Rest. Do NOT induce vomiting. Refer immediately for medical attention. |
SPILLAGE DISPOSAL | CLASSIFICATION & LABELLING |
---|---|
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable non-plastic containers. Do NOT absorb in saw-dust or other combustible absorbents. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. |

OCCUPATIONAL EXPOSURE LIMITS |
---|
TLV: 0.01 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans). MAK: skin absorption (H); sensitization of skin (SH); carcinogen category: 2; germ cell mutagen group: 3A |
ENVIRONMENT |
---|
The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. |
NOTES |
---|
Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT take working clothes home. Rinse contaminated clothing with plenty of water because of fire hazard. |
