EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION Cough. Abdominal cramps. Dizziness. Headache. Confusion.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •EYES Redness. Pain.
Face shield or eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
 •INGESTION Nausea. Vomiting. Abdominal pain. Diarrhoea.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Let solidify if molten. Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.
Separated from strong oxidants. Dry.
