6 Packaging, marking, transportation and storage

6.

Industrial Ethylene Oxide should be packed in stainless steel cylinders, or be filled in tankers with stainless steel.

6.

Industrial ethylene oxide should be firmly on the packaging container mark, indicating the product name, manufacturer name and address, trademark, production date or batch number, quality grade, net mass, production license number and serial number of this standard and so on

6.
3 Transportation and storage

The storage and transportation of steel cylinders filled with industrial ethylene oxide shall be carried out in accordance with the "Cylinder Safety Supervision Regulations"
.

Tank trucks filled with industrial ethylene oxide should be transported under a nitrogen seal.
The volume fraction of nitrogen should not be less than 99.
9%, the volume fraction of oxygen in the sealed nitrogen should not exceed 0.
5%, and the pressure of the sealed nitrogen should be 0.
28MPa～0.
35MPa
.
In addition, it should also implement the "Pressure Vessel Safety Technical Supervision Regulations", "Liquefied Gas Tank Truck Safety Supervision Regulations" and other relevant regulations
.

The material of industrial ethylene oxide storage tank should be stainless steel
.
Storage tanks containing industrial ethylene oxide should be sealed with nitrogen, the volume fraction of nitrogen should not be less than 99.
9%, the volume fraction of oxygen in the nitrogen sealing should not be greater than 0.
5%, the sealing pressure of nitrogen should be 0.
07MPa～0.
35MPa, and the storage temperature should not be less than 99.
9%.
Above 10°C
.

7 security

7.
1 Ethylene oxide is a flammable and explosive toxic liquid with a boiling point of 10.
7°C, a flash point of -17.
8°C, and a self-ignition point of 429°C.
The volume fraction of the explosion limit is 3% to 100%
.
When the temperature is higher than 40°C, ethylene oxide starts to polymerize
.
Ethylene oxide can decompose or polymerize when it comes in contact with catalysts (such as aluminum chloride , iron oxides, aluminum oxide , potassium metal, acids, alkalis), releasing a lot of heat, and can cause explosions in severe cases
.

7.
2 Ethylene oxide is a strong anesthetic, which can cause acute and chronic poisoning
.
Short-term inhalation of low-concentration ethylene oxide vapor can irritate the eyes and nose and cause congestion of the swelling.
Short-term exposure to high-concentration ethylene oxide vapor can cause headache, nausea, vomiting and difficulty breathing
.
Liquid ethylene oxide can cause skin frostbite if it comes in contact with the skin
