ACUTE HAZARDS | PREVENTION | FIRE FIGHTING | |
---|---|---|---|
FIRE & EXPLOSION | Highly flammable. Heating will cause rise in pressure with risk of bursting. Vapour/air mixtures are explosive. | NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. | Use dry powder, foam, carbon dioxide. NO water. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position. |
AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! | |||
---|---|---|---|
SYMPTOMS | PREVENTION | FIRST AID | |
Inhalation | Cough. Sore throat. Laboured breathing. Burning sensation. | Use ventilation, local exhaust or breathing protection. | Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention. |
Skin | Redness. Pain. Skin burns. | Protective gloves. Protective clothing. | Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . |
Eyes | Redness. Pain. Burns. | Wear safety goggles or eye protection in combination with breathing protection. | Rinse with plenty of water for several minutes (remove contact lenses if easily possible). |
Ingestion | Abdominal pain. Burning sensation. Shock or collapse. | Do not eat, drink, or smoke during work. | Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention. |

NOTES |
---|
Some isocyanates are well known to cause respiratory sensitization. However, there are no reports of n-butyl isocyanate or other monoisocyanates causing respiratory sensitization. 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. |
