2.3 First Aid
Swallowed
If victim is conscious and productive vomit has not already occurred, remove poison by ipecac emesis or gastric lavage. Maintain airway, respiration and blood pressure. Obtain medical attention. Administration of gastric lavage should be performed by qualified medical personnel.
Eye
Wash eyes immediately with large amounts of water or normal saline, occasionally lifting upper and lower lids, until no evidence of chemical remains (at least 15-20 minutes). Get medical attention immeidately.
Skin
Remove contaminated clothing and shoes immediately. Wash with soap or mild detergent and large amounts of water until no evidence of chemical remains (at least 15-20 minutes). Get medical attention immediately.
Inhaled
Remove from exposure area to fresh air immediately. Perform artificial respiration if necessary. Keep person warm and at rest. Treat symptomatically and supportively. Obtain medical attention immediately.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
In single ingestion episodes, give syrup of ipecac and/or perform gastric lavage if productive vomitnig has not already occurred. Activated charcoal does not bind the lithium effectively and is not useful in isolated lithium toxicity. Raising the sodium intake does not increase lithium clearance. Treat symptomatically based on individual reactions of patient and judgement of doctor.
