SECTION IV – FIRST AID MEASURES
4.1 Description of the first-aid measures
General information:
After inhalation: Remove person to fresh air. If breathing is difficult, administer oxygen. If not
breathing, give artificial respiration. In case of unconsciousness, place patient stably in side position
for transportation.
After skin contact: Wash skin with cool water and pH-neutral soap or a mild detergent. If
significant skin irritation or rash occurs: get medical advice or attention.
After eye contact: Rinse cautiously with water for several minutes. Remove contact lenses, if
present and easy to do. Continue rinsing.
After swallowing: Do not induce vomiting. If conscious, have the victim drink plenty of water and
call a physician immediately. Never give anything by mouth to an unconscious person.
4.2 Most important symptoms/effects, acute and delayed

repeated inhalation. This product contains crystalline silica. Prolonged or repeated inhalation of
respirable silica from this product can cause silicosis.
Skin contact: Causes skin irritation. Handling can cause dry skin, discomfort, irritation, and
dermatitis. May cause sensitization by skin contact. Product becomes extremely alkaline when
exposed to moisture, and can cause alkali burns and affect the mucous membranes. Precautions
must be observed because burns occur with little warning -- little heat is sensed.
