First aid measures
Description of necessary first-aid measures
Inhalation: Remove the subject from the contaminated area as soon as possible.Transport subject lying down, with the head higher that the body,to a quiet ,uncontaminated and well ventilated location. Administer oxygen (2 .5%calcium gluconate if available ,can be oxygen nebulised with trained personnel)or cardiopulmonary resuscitation if necessary and as soon a possible. If patient is unconscious,give artificial respiration.
Note: Mouth to mouth resuscitation is not recommended. Keep warm (blanket).Seek medical advice in all cases.Take to a hospital.
Skin: Immediately bring the clothed subject under the shower.Remove contaminated shoes, socks and clothing; while washing the affected skin with running water for 5 minutes.
Double bag all contaminated clothing for disposal. Immediately apply calcium glu conate gel 2.5%and massage into the affected area using rubber gloves; continue to massage while repeatedly applying gel until 15 minutes after pain is relieved. 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. Do not use oily drops, ointment ,or HF skin burn treatments. Consult an ophthalmologist or eye specialist immediately in all cases. Take to a hospital immediately.
Ingestion: Consult a physician immediately in all cases.Take to a hospital.
