3 2 - H373No data MixturesNot ApplicableCommentNaturally occuring mineral. This product contains a small quantity of quartz, crystalline silica. Prolonged and repeated exposure toconcentrations of crystalline silica exceeding the workplace exposure limit (WEL) may lead to chronic lung disease such assilicosis. IARC Monographs, Vol. 68, 1997, concludes that there is sufficient evidence that inhaled crystalline silica in the form ofquartz or cristobalite from occupational sources causes cancer in humans. IARC Classification Group First aid of first-aid measuresInhalationIf inhaled, remove from area to fresh air. Get medical attention if respiratory irritationdevelops or if breathing becomes mouth.

4 Do not induce vomiting without medical advice. Never give anything by mouthto an unconscious person. Get medical attention if symptoms contactPage 2 / 11 Wash off immediately with soap and plenty of water removing all contaminated clothes andshoes. Get medical attention immediately if symptoms (All Grades) Safety data Sheet numberMI11713 Revision date02/Apr/2014 Eye contactRemove contact lenses. Promptly wash eyes with lots of water while lifting eye to rinse for at least 15 minutes. Get medical attention if any discomfort important symptoms and effects, both acute and delayedGeneral adviceThe severity of the symptoms described will vary dependant of the concentration and thelength of exposure.
