SECTION 3: Hazards Identification
Emergency Overview:	Extremely flammable, reacts violently with moisture causing chemical burns on prolonged contact with human tissue. Inhalation of ether vapors can cause intoxication, drowsiness, stupor and unconsciousness. Harmful if swallowed.
Primary Routes of Exposure:	Ingestion, inhalation, skin, eyes.
Eye Contact:	Corrosive to the eyes. May cause severe eye damage.
Skin Contact:	Causes burns to the skin.
Inhalation:	Inhalation of ether vapors causes intoxication, drowsiness and unconsciousness.
Ingestion:	Corrosive to mouth, throat and gastrointestinal tract. Harmful if swallowed.
Acute Health Effects:	Causes burns to skin, eyes and respiratory tract. Inhalation of ether vapors causes intoxication, drowsiness, stupor and unconsciousness. Lithium salts are toxic to the central nervous system.
Chronic Health Effects:	Ingestion of Inorganic bromides may produce depression, psychosis and mental deterioration. Death, due to respiratory failure, may result from severe and continued exposure to ether. Lithium salts are toxic to the central nervous system and may damage kidneys.
NTP:	No
IARC:	No
OSHA:	No

SECTION 4: First Aid Measures
Eye Exposure:	Immediately flush the eyes with copious amounts of water for at least 15 minutes. A victim will need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area immediately with water. Remove contaminated clothing if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove victim to fresh air immediately. Keep the victim lying down and warm. Give oxygen as soon as possible. If shock occurs, respond with appropriate first aid. Transport the victim to a hospital.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give water to dilute the toxin (only if conscious). Induce vomiting only if directed by medical personnel.
