Section 4: First Aid Measures
In case of accidental exposure, this section provides first aid measures. For diethyl ether, the recommended actions include:
- Inhalation: Move the person to fresh air and keep them at rest in a position comfortable for breathing. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
- Skin Contact: Immediately wash the affected area with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes.
- Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, lifting the upper and lower eyelids occasionally. Seek medical attention if irritation persists.
- Ingestion: Do not induce vomiting. Rinse the mouth and drink plenty of water. Seek medical attention immediately.
Section 5: Fire-Fighting Measures
Diethyl ether is highly flammable, and this section provides guidelines for extinguishing fires involving the chemical. It recommends using dry chemical, carbon dioxide, or foam extinguishers. Water should not be used as it can spread the fire. Firefighters should wear appropriate protective gear, including self-contained breathing apparatus.
Section 6: Accidental Release Measures
This section outlines the steps to take in case of a spill or leak. For diethyl ether, the recommended actions include:
- Ventilate the area to disperse the vapors.
- Absorb the liquid with inert material and place it in a suitable container for disposal.
- Avoid sources of ignition.
- Wear appropriate personal protective equipment (PPE).
Section 7: Handling and Storage
Proper handling and storage are crucial for preventing accidents. This section provides guidelines for safe handling practices and storage conditions. Diethyl ether should be stored in a cool, dry, well-ventilated area away from sources of ignition. Containers should be tightly closed when not in use, and ground all equipment containing material.
Section 8: Exposure Controls/Personal Protection
This section details the exposure limits and personal protective equipment (PPE) required when handling diethyl ether. The recommended exposure limits are:
| Type | Limit |
|---|---|
| Time-Weighted Average (TWA) | 400 ppm (1200 mg/m³) |
| Short-Term Exposure Limit (STEL) | 500 ppm (1500 mg/m³) |
PPE should include safety glasses with side shields, chemical-resistant gloves, and protective clothing. In case of potential inhalation, use a respirator with an organic vapor cartridge.
Section 9: Physical and Chemical Properties
This section provides detailed information on the physical and chemical properties of diethyl ether. Key properties include:
- Appearance: Colorless liquid
- Odor: Characteristic ether odor
- Boiling Point: 34.6°C
- Melting Point: -116.3°C
- Vapor Pressure: 58.6 kPa at 20°C
- Vapor Density: 2.55 (air = 1)
- Solubility in Water: Slightly soluble
Section 10: Stability and Reactivity
This section discusses the stability of diethyl ether and its potential reactivity with other substances. Diethyl ether is stable under normal temperatures and pressures but can form explosive peroxides upon exposure to air. It is incompatible with strong oxidizing agents and should be kept away from heat, sparks, and open flames.
Section 11: Toxicological Information
This section provides detailed information on the toxicological effects of diethyl ether. It includes data on acute and chronic toxicity, as well as carcinogenicity and reproductive toxicity. Diethyl ether is classified as a Category 2 carcinogen by the International Agency for Research on Cancer (IARC). It can cause central nervous system depression, skin and eye irritation, and respiratory irritation.
Section 12: Ecological Information
This section outlines the environmental impact of diethyl ether. It is highly volatile and can contribute to air pollution. It is also toxic to aquatic life and should be disposed of according to local regulations to prevent environmental contamination.
Section 13: Disposal Considerations
Proper disposal of diethyl ether is essential to prevent environmental and health hazards. This section provides guidelines for safe disposal. Diethyl ether should be disposed of in accordance with local, state, and federal regulations. It should not be poured down drains or into the environment. Containers should be properly labeled and stored until disposal.
Section 14: Transport Information
This section provides information on the safe transport of diethyl ether. It includes UN numbers, proper shipping names, and hazard classes. Diethyl ether is classified as a flammable liquid and should be transported in accordance with the regulations for hazardous materials.
