SECTION 4: First aid measures
4.1 Description of first aid measures
General information:
Remove breathing equipment only after contaminated clothing have been completely removed.
In case of irregular breathing or respiratory arrest provide artificial respiration.
Immediately remove any clothing soiled by the product.
Seek immediate medical advice.
First aiders shall pay attention to self-protection.
After inhalation:
Supply fresh air. If required, provide artificial respiration. Keep patient warm. Consult a doctor if symptoms persist.
In case of unconsciousness place patient stably in side position for transportation.
After skin contact:
After rinsing with water thoroughly, apply 2.5% Ca-gluconate solution or Ca-gluconate gel immediately. Do not rub
hard.
Apply the solution or the gel every 1-2 hours. Continue applying them every several hours even after the pain iseased.
If they are not at hand, keep rinsing with warm water for at least 30 minutes and call for a doctor immediately. Hand
this SDS to the doctor.
After eye contact: Rinse opened eye for several minutes under running water. Then consult an opthalmologist.
After swallowing:
Do not induce vomiting; Consult a doctor immediately.
Drink plenty of water and provide fresh air. Consult a doctor immediately.
4.2 Most important symptoms and effects, both acute and chronic:
After skin contact: the affected skin becomes painful and red.
After eye contact: irritation of the mucous membranes.
After swalloing: nausea, stomachache.
Protection of rescuers: Wear self-contained breathing apparatus and fully protective suit to avoid contact with toxicsubstances.
4.3 Indication of any immediate medical attention and special treatment needed:
Medical supervision for at least 48 hours.
