EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS!

•INHALATION Cough. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain. Blurred vision.
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 take to a doctor.
•INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest.
