4.1Description of necessary first-aid measures
If inhaled
Fresh air, rest. Refer for medical attention.

Following skin contact
Remove contaminated clothes. Rinse skin with plenty of water or shower.

Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Following ingestion
Rinse mouth. Do NOT induce vomiting. Give nothing to drink. Refer for medical attention .

4.2Most important symptoms/effects, acute and delayed
Inhalation of mist causes coughing and irritation of mucous membranes. Ingestion, even of diluted preparations, has a corrosive effect on the esophagus and stomach. Contact with more concentrated solutions can cause severe burns of skin or eye. (USCG, 1999)

4.3Indication of immediate medical attention and special treatment needed, if necessary
Immediate First Aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention.
