Table of Physical and Chemical Properties and Hazardous Characteristics of Ether

Chemical name

Chinese name: 乙醚  English name: ethyl ether CAS No.: 60-29-7          Molecular formula: C4H10O Molecular weight: 74.12

Hazard Code: 31026 Hazard Category: Class 3.1 Low Flash Point Flammable Liquid UN Number: 1155


Hazard Overview

Health hazards: The main function of this product is general anesthesia. Acute massive exposure can lead to early excitement, followed by drowsiness, vomiting, pale complexion, bradycardia, decreased body temperature, and irregular breathing, which can be life-threatening. The temporary effects after acute contact include headache, irritability or depression, salivation, vomiting, decreased appetite, and excessive sweating. Liquids or high concentration vapors are irritating to the eyes. Chronic effects: Long term low concentration inhalation can cause headaches, dizziness, fatigue, drowsiness, proteinuria, and polycythemia. Long term skin contact can cause dryness and cracking of the skin.

Explosive hazard: This product is extremely flammable and irritating.


Emergency measures

Skin contact: Remove contaminated clothing and rinse with plenty of running water.

Eye contact: Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention.

Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.


Fire protection measures

Dangerous characteristics: Its vapor and air can form explosive mixtures, which are highly flammable and explosive when exposed to open flames and high heat. Can react strongly with oxidants. After being left in the air for a long time, it can generate explosive peroxides. In a fire scene, heated containers pose a risk of explosion. Its vapor is heavier than air and can spread to a considerable distance at lower levels. It will ignite and reignite when exposed to a source of fire.

Harmful combustion products: carbon monoxide, carbon dioxide.

Fire extinguishing method: Move the container from the fire scene to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished. If the container in the fire has changed color or produced sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: insoluble foam, carbon dioxide, dry powder, sand. Using water to extinguish the fire is ineffective.


Emergency response to leakage

Quickly evacuate personnel from the contaminated area to a safe zone, isolate them, and strictly restrict their entry and exit. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static work clothes. Cut off the leakage source as much as possible. Prevent the flow into restricted spaces such as sewers and drainage ditches. Minor leakage: Absorb with activated carbon or other inert materials. You can also rinse with a large amount of water, dilute the washing water, and put it into the wastewater system. Massive leakage: Construct embankments or dig pits to contain it. Cover with foam to reduce steam disaster. Transfer to a tanker or dedicated collector using an explosion-proof pump, and recycle or transport to a waste disposal site for disposal.


Handling and Storage

Precautions for operation: Closed operation, comprehensive ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear filter type gas masks (half face masks), chemical safety goggles, anti-static work clothes, and rubber oil resistant gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid contact with oxidants. Fill appropriately, leaving 5% empty volume. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.

Storage precautions: Usually, products are added with stabilizers. Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 26 ℃. The packaging requires sealing and must not come into contact with air. It should be stored separately from oxidants and avoid mixing storage. Not suitable for large-scale storage or long-term storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.

Transportation information

Packaging method: Small opening steel drum; Ordinary wooden box outside the ampoule bottle; Screw mouth glass bottles, iron cap pressed mouth glass bottles, plastic bottles, or ordinary wooden boxes outside metal drums (cans).

Transportation precautions: Railway transportation is used. When using small opening steel drums for packaging from April to September each year, refrigerated transportation is limited. Transport vehicles should be equipped with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks during transportation. It is best to transport in the morning and evening during summer. The tank truck used for transportation should have a grounding chain, and a perforated partition can be installed inside the tank to reduce static electricity generated by vibration. It is strictly prohibited to mix and transport with oxidants, edible chemicals, etc. During transportation, it should be protected from direct sunlight, rain, and high temperatures. When stopping midway, one should stay away from sources of fire, heat, and high temperature areas. The exhaust pipe of the vehicle carrying the item must be equipped with a flame retardant device, and the use of mechanical equipment and tools that are prone to generating sparks for loading and unloading is prohibited. When transporting by road, follow the prescribed route and do not stay in residential or densely populated areas. It is prohibited to slip during railway transportation. It is strictly prohibited to use wooden boats or cement boats for bulk transportation.
