Fumigation disinfection is a common and effective method of sterilization, widely used in medical institutions, food processing plants, laboratories and other places that require a highly clean environment. Through the use of hot steam or chemicals, fumigation disinfection can completely kill bacteria, viruses, fungi and other pathogens, thus effectively preventing the spread of infectious diseases. In this article, we will introduce the operation steps and precautions for fumigation disinfection.
Operating steps
Step 1: Select the appropriate fumigation disinfectant
The choice of fumigation disinfectant should be based on the types of pathogens that need to be killed and the characteristics of the environment in which it is used to determine. Common fumigant disinfectants include peroxyacetic acid, formaldehyde, chlorine and so on. Peroxyacetic acid is widely used in medical institutions, has a high bactericidal effect and is less polluting to the environment. Formaldehyde is a toxic gas, mainly used in laboratories and other special environments. Chlorine gas, on the other hand, is commonly used in food processing plants and other places.
Step 2: Preparation of fumigation equipment
According to the selected fumigant disinfectant, prepare the corresponding fumigation equipment. Common fumigation equipment includes hot steam generators, fumigation boxes, fumigation chambers and so on. Hot steam generators are used in places where hot steam is used for fumigation and disinfection by heating water to produce high-temperature steam. Fumigation boxes and chambers are used in places where chemicals are used for fumigation and disinfection by spraying or releasing fumigants into the air.
Step 3: Pretreatment
Before fumigation, the items to be disinfected need to be pretreated. First, the items to be disinfected are cleaned to remove surface dirt and impurities. Then, the articles are classified and grouped according to different materials and sizes for easy operation and better results when fumigating and disinfecting.
Step 4: Fumigation
According to the selected fumigant and fumigation equipment, follow the corresponding operation steps for fumigation. For the use of hot steam fumigation disinfection of the premises, the first hot steam generator heated to a set temperature, and then the steam into the fumigation room or fumigation box, to maintain a certain period of time. For places where chemical substances are used for fumigation and disinfection, the fumigant is sprayed or released into the air at a specified concentration and dosage, and kept for a certain time.
Step 5: Ventilation
After the fumigation and disinfection is finished, ventilation is needed to exhaust the fumigant residues and harmful gases. Open doors and windows to ensure indoor and outdoor air circulation to accelerate the evaporation and dilution of the fumigant. At the same time, the use of air purifiers and other equipment for air purification to further improve indoor air quality.
Precautions
Precautions 1: safety protection
When fumigating and disinfecting, you should strictly follow the safety regulations and wear protective gear, such as gloves, masks and goggles. Avoid contact with fumigants and harmful gases that may cause harm to the body.
Note 2: pay attention to environmental adaptability
Different fumigant disinfectants are suitable for different environments and items. At the same time, pay attention to the adaptability of the fumigant to avoid damage to some special materials and articles.
Precautions 3: Strictly control the dose and time
The dose and time of the fumigant disinfectant is an important factor to ensure the disinfection effect. According to the types of pathogens and the characteristics of the environment, we should strictly control the dose of fumigant and fumigation time to ensure that the disinfection effect meets expectations.
Note 4: Regular testing of disinfection effect
Regular testing of disinfection effect is an important part of ensuring fumigation disinfection. This can be done by collecting samples for laboratory testing or using bio-indicators for on-site testing to assess whether the disinfection effect meets the requirements. If the disinfection effect is found to be unsatisfactory, the dose of fumigant used and the fumigation time should be adjusted in time, or other measures should be taken to improve the disinfection effect.
Conclusion
Fumigation disinfection as an effective sterilization method, widely used in various fields. By choosing the right fumigant disinfectant and fumigation equipment, and following the correct operating steps for fumigation disinfection, the pathogens can be completely killed to ensure the cleanliness and safety of the environment. However, when carrying out fumigation and disinfection, we also need to pay attention to safety protection, environmental adaptability, dosage and time control, as well as regular testing of the disinfection effect. Only under the premise of strict compliance with operating procedures and precautions, fumigation disinfection can maximize the effect and protect our health and safety.
