How to disinfect surgical mask

How to disinfect disposable masks?

Ethylene oxide sterilizer is used for disinfection. Generally, 6 cubic sterilizer consumes 3.6-4.8kg ethylene oxide at a time.

Why does the production mask use the ring disinfection cabinet?

Ethylene oxide disinfection cabinet is a kind of commonly used sterilization equipment. Under certain conditions, it uses ethylene oxide gas to fumigate the masks and other items sealed in the sterilization room at low temperature to achieve sterilization.
Ethylene oxide can destroy all kinds of microorganisms. It has strong penetrability and can penetrate microporous cotton wool products, plastic films, cartons and other packaging items. The disposable mask after sterilization is placed in a well ventilated room and can be used safely after volatilization.

Precautions for ethylene oxide sterilizer

1. The following sterilization conditions can be used:
Ethylene oxide concentration 450-1200mg / L
Relative humidity 50% - 80% . 
Temperature 37-63 ℃
Sterilization time 90-300min.
2. During loading, the clearance between articles shall be 10 mm, and the loading capacity shall not exceed 80% of the volume of the inner chamber, so as to facilitate the smooth flow of ethylene oxide gas. According to the requirements of the technical code for disinfection of medical and health institutions issued by the Ministry of health, the residual ethylene oxide in sterilized articles shall be less than 10mg / kg.
3. Ethylene oxide is flammable and explosive. When 3% ethylene oxide is contained in the air, explosive mixture gas will be formed, and combustion or explosion will occur in case of open fire. Therefore, the sterilizer and gas tank must be away from the fire source (such as matches, cigarette butts and electrical places prone to flash static electricity and sparks).
4. in case of combustion, water spray or foam extinguishing agent, carbon disulfide extinguishing agent and dry powder extinguishing agent should be used; if not timely plugging, it should be allowed to burn and transfer the container from the fire site.
5. Ethylene oxide has moderate toxicity. A large number of acute or chronic inhalation of ethylene oxide, eye contact, skin contact and digestive tract contact with ethylene oxide are harmful to human body.
