EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Blue lips or finger nails. Blue skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES
Face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
