Apply water longer (15 minutes) if calcium glu conate is not available.If finger/finger nails are touched,even if there is no pain, dip them in a bath of 5% calcium glu conate for 15 to 20 minutes. Keep warm (blanket), provide clean clothing. Consult a physician immediately in all cases of skin contact no matter how minor. Take to a hospital immediately.

Eye: Flush eyes with running water for 5 minutes,while keeping the eyelids wide open. Rinse the eyes with a calcium gluconate 1%solution in physiological serum (10 mlof calcium glu conate 10% in 90 ml of physiological serum) for 10 minutes.Continue a calcium gluconate drip into eyes …Then drop wise while transporting. If 1%calcium gluconate is not available continue flushing with water.In the case difficulty opening the eyelids, administer an analgesic eye wash.
