Can you store chemical hazards in your refrigerator?

In recent years, there have been several hospitals across the country that store ether refrigerators. Why is that? Although there is no fire source in the refrigerator, there is a power supply, and ordinary non-explosion-proof electrical appliances are used.

Since the temperature of the refrigerator is automatically controlled, when the temperature is lower than a certain value, the power supply will be cut off by itself; If the temperature is higher than a certain value, the power supply will be automatically switched on. As a result, when the power supply is switched on or off, electrical sparks often erupt from the contacts of the control elements. Dangerous goods that need to be stored at low temperatures have a very low flash point and boiling point, such as ether, which has a flash point of only -45 degrees Celsius.

Although the temperature inside the refrigerator is around 0 degrees, it still greatly exceeds the flash point of ether. So, if there is a slight gap in the container, there will be an ether vapor leak. The refrigerator is sealed, so the gas cannot escape and accumulates inside the box.

A refrigerator with a capacity of 100 liters, as long as about 6 grams of ether volatilizes into gas, can fill the box with **sexual mixture, which can occur in case of electric sparks**. Therefore, you must not think that the dangerous goods stored in the refrigerator are foolproof and absolutely safe. @陈湘华 (1 page in this article) How to get this article

That's how I studied chemistry. You can't kill this question with one shot, and say yes or no. It depends on what you want to store and for how long.

We have a lot of things in the fridge, and very few can't put in the fridge. There are some things that don't need to be in the fridge.

Tell me the name of what you're going to put in and I'll tell you if I can put it in.

Do not use a mechanical temperature-controlled refrigerator. Explosion-proof refrigerators (at least electronically temperature-controlled frosted refrigerators) should be used to store chemical reagents. Mechanical temperature-controlled frost-type refrigerators are not allowed to store chemical reagents without explosion-proof nuclear plexus modification, and mechanical temperature-controlled frost-free refrigerators are prohibited from storing chemical reagents.

Ordinary refrigerators are not allowed to store volatile organic solvents.

In principle, the laboratory shall not use the refrigerator beyond the time limit (generally the rule is to change the silver cherry blossom for 10 years).

Differential treatment of chemical storage:

Compounds with low boiling points and drugs that need to be stored at low temperatures must be placed in the required ring freezer (cryogenic freezer) as required.

Drugs and reagents prepared in the dark should be stored in brown containers (bottles) or wrapped in dark paper as required.

Medicines, all medicines, should be placed in the medicine cabinet and should not be mixed with the prepared solution.

Liquid medicines are placed in low cabinets. Solid medicines are kept separate from liquid medicines.

Summary. Hello, there are three ways to store hazardous chemicals: isolated storage, separated storage, and separate storage. There are special dangerous goods storage cabinets.

Any amendments made when filling in the documents need to be marked with a reference document next to it.

Yes. When the material is classic, the food should be inspected first, and then differentiated according to the completeness of the packaging area, and then the quantity of the list should be separately, of which the bulk box packaging packaging material must.

What are you asking?

What principles should be observed in the material receiving, receiving and storage operation, and what are the placement operation rules?

1. There should be instructions: production plan, picking list, etc. 2. First-in, first-out principle.

3. The accounts and tents are consistent with the side sheds. 4. Regular protection and inspection to ensure the quality of material audits. 5. Regular inventory.

6. After the goods are issued, the accounts will be placed in time and the accounts will be processed.

Laboratories should not use mechanical temperature-controlled refrigerators for storing chemicals.

To store chemical reagents, use an anti-explosion refrigerator (at least an electronic temperature-controlled frost refrigerator). Mechanical temperature-controlled frost-type refrigerators are not allowed to store chemical reagents without explosion-proof modification, and mechanical temperature-controlled frost-free refrigerators are prohibited from storing chemical reagents. Ordinary refrigerators are not allowed to store volatile organic solvents.

In principle, the laboratory shall not use the refrigerator beyond the time limit (the general provision is 10 years).

The Work Safety Law of the People's Republic of China and the Regulations on the Safety Management of Hazardous Chemicals are explained.

Work Safety Law of the People's Republic of China

Excerpt: Article 96 The meaning of the following terms in this pharaoh's circle:

Dangerous goods refer to flammable and explosive materials, hazardous chemicals, radioactive materials and other materials that can endanger personal safety and property safety.

Major hazard sources refer to units (including sites and facilities) that produce, handle, use or store dangerous goods on a long-term or temporary basis, and the quantity of dangerous goods is equal to or exceeds the critical amount

Regulations on the Safety Management of Hazardous Chemicals

Excerpt: Article 2 The production, operation, storage, transportation and use of hazardous chemicals and the disposal of waste hazardous chemicals within the territory of the People's Republic of China shall comply with the provisions of these Regulations and the relevant national laws and other administrative regulations on production safety.
