| 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. Possible risk of irreversible effects. |
| 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: | Corrosive to skin, eyes, and respiratory tract. Inhalation of ether vapors causes intoxication, drowsiness, stupor and unconsciousness. |
| 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. Possible risk of irreversible effects. |
| 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 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel. |
