Methyl formate boiling point (, flash point (-32): belongs to the extremely flammable liquid in Table 2, with a critical amount of 10 tons.

Ethyl formate has a boiling point ( , flash point (-20) belongs to the highly flammable liquids in Table 2 with a critical amount of 1000 tons.

Hello, these two are not in GB18218-2009 Only ethyl acetate methyl formate Dangerous goods number: 31037 Low flash point flammable liquid ethyl formate Dangerous goods number: 31038 Low flash point flammable liquid According to Table 2, extremely flammable liquid:

Liquids with a boiling point less than or equal to 35 degrees and a flash point less than 0 degrees, or.

Both of these substances can be launched at a critical level of 10 tons.

For the above two substances, the production site shall not exceed 2t, and the storage site shall not exceed 20t.

Hello "What is the critical amount in hazardous chemicals?" The "critical quantity" (GB18218-2009 identification of major hazard sources of hazardous chemicals) is: the critical quantity thresholdquantity refers to the quantity specified for a certain or certain class of hazardous substances, if the quantity of substances in the unit is equal to or exceeds the quantity, the unit is designated as a major hazard source.

It is clearly stipulated in the "GB18218-2009 Identification of Major Hazard Sources of Hazardous Chemicals". This refers to the amount of "stockpile", and its "quantity" reaches or exceeds that is a "major source of danger".

The critical amount of alcohol as a major hazard source of hazardous chemicals is greater than 500 tons.

The main thing is to seal and protect from light! Because it's volatile!

Hope mine can help you! Thank you!

Ethyl acetate (ethyl acetate) containers should be well sealed to prevent leakage. Stored in:

Cool and ventilated place, away from heat and fire. Separate from the oxidant.

In general, it is a concept established in accordance with GB18218 (Identification of Significant Hazards), which refers to the fact that if the hazardous chemicals in the storage or production site exceed the critical amount, then the area constitutes a significant hazard. For more information, please refer to GB18218

Hello "What is the critical amount in hazardous chemicals?" The "critical amount" (GB18218-2009 Identification of major hazard sources of hazardous chemicals) in GB18218-2009 is:

Threshold quantity refers to the quantity specified for a certain or class of hazardous substances, if the quantity of the substance in the unit is equal to or exceeds the quantity, the unit is designated as a major hazard source.

It is clearly stipulated in the "GB18218-2009 Identification of Major Hazard Sources of Hazardous Chemicals".

This refers to the amount of "stockpile", and its "quantity" reaches or exceeds that is a "major source of danger".

The critical amount of liquid oxygen is 200 tons.

Identification basis: according to the identification of major hazard sources of hazardous chemicals (GB18218-2009) - oxidizing gases: gases whose hazards belong to 2 2 items of non-flammable and non-toxic gases and whose secondary hazards are 5 categories; The criteria for the identification of major hazards are a method that stipulates the basis and method for identifying major hazards, as well as the method for calculating the critical amount and maximum amount of major hazards.

The criteria for the identification of major hazards stipulate the basis and methods for identifying major hazards, as well as the methods for calculating the critical amount and maximum amount of major hazards.
