First-aid measures
DESCRIPTION OF FIRST AIRD MEASUREMENTS
General advice:
First Aid responders should pay attention to self-protection and use the recommended protective clothing
Move out of dangerous area.
Take off contaminated clothing and shoes immediately.
Keep warm and in a quiet place.
If inhaled:
Provide fresh air.
If not breathing, give artificial respiration.
Keep the victim calm and in a semi-upright position.
Consult a physician.
In case of skin contact:
Wash off immediately with plenty of water for at least 15 minutes.
Call a physician immediately.
In case of eye contact:
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Call a physician immediately.
If swallowed:
Clean mouth with water and drink afterwards plenty of water.
Never give anything by mouth to an unconscious person.
Do NOT induce vomiting.
Call a physician immediately.
MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED
Symptoms:
Symptoms of poisoning may appear several hours later.
Risks:
If swallowed, severe burns in the oral cavity and throat as well as danger of perforation of the digestive tract and stomach.
INDICATION OF ANY IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED
Treatment:
Treat symptomatically.
For specialist advice physicians should contact the Poisons Information Service.
Keep under medical supervision for at least 48 hours.
