The safety storage and transportation specification
of ethylene ketone in the field of chemical production raw materials
1. Introduction

ethylene ketone is an important organic chemical raw material, widely used in polymer synthesis, medicine, pesticides and other fields. However, ketene has extremely high reactivity and toxicity, and requires extremely high safety during storage and transportation. In order to ensure the safety of ketene during production, use and transportation, it is important to establish strict storage and transportation regulations.

2. the physical and chemical properties of ketene

ketene is a colorless and transparent liquid with a pungent odor. It is highly volatile and easily decomposed in the air to produce toxic acetaldehyde and carbon dioxide. Ketene has a low boiling point and is easily gasified, so it needs special attention during storage and transportation.

3. the toxicity and harm
of
ketene has high toxicity to human body, and can enter the human body through inhalation, skin and eye contact, causing poisoning symptoms. Long-term exposure to ketene may cause serious consequences such as nervous system damage, liver and kidney dysfunction.

4. safety storage specifications for ketene

1. Storage facilities: ketene should be stored in a cool, dry, well-ventilated special warehouse, away from fire, heat and direct sunlight. The warehouse floor shall be anti-skid and equipped with corresponding fire fighting equipment.
2. Storage container: Ketene should be stored in a special stainless steel or glass fiber reinforced plastic container, and the container should be well sealed to prevent leakage.
3. Storage limits: The amount of ketene stored in a single warehouse should not exceed the specified limits to reduce potential risks.
4. Safety management: storage facilities should be managed by special personnel, and regular safety inspection and equipment maintenance should be carried out to ensure storage safety.

5. safety of ketene transport specifications

1. Transport vehicles: ketene should be transported by special tank trucks, and the vehicles should have good sealing performance and anti-static facilities.
2. transport personnel: transport personnel should be professionally trained, familiar with the nature of ketene and safe operation procedures.
3. Transportation route: The transportation route should choose the route with smooth road and smooth traffic as far as possible, and avoid driving in prosperous urban areas or densely populated areas.
4. Emergency measures: corresponding emergency equipment and protective articles, such as fire extinguishers and leakage emergency treatment kits, shall be provided during transportation.

6. Ketene Leakage Treatment Specification

1. Evacuation: In the event of a ketene leak, the people nearby should be evacuated immediately, and a cordon should be set up to prohibit irrelevant personnel from entering the leakage area.
2. Cut off the fire source: cut off all fire sources near the leakage area to prevent the ketene from causing fire or explosion.
3. Leakage treatment: Use special adsorption materials or containment equipment to collect and process the leaked ketene to avoid its diffusion into the environment.
4. Environmental monitoring: After the leakage treatment is completed, the surrounding environment should be monitored to ensure that the air quality meets the standard before the alert can be lifted.

7. conclusion

ketene, as an important chemical raw material, has a high safety risk in the process of production, use and transportation. In order to ensure its safety, it is necessary to formulate strict storage and transportation specifications, strengthen safety management and operation training, and improve the safety awareness and operation skills of relevant personnel. Only in this way can we minimize the safety risk of ketene and protect the safety of people's lives and property.
