According to the requirements of the Work Plan for Detection and Preventive Disinfection of Imported High-risk Non-cold Chain Container Cargoes, Technical Guidelines for the Preventive Disinfection and Protection of the Surface of the Inside of the Imported High-risk Non-cold Chain Containers and the Surface of the Outsourcing Packaging of the Cargoes Loaded with the Containers are hereby developed.
I. Scope of Application
This guideline is applicable to the preventive disinfection of high-frequency contact parts such as the outer packaging of goods in imported high-risk non-cold-chain containers from high-risk countries, the inner wall of the containers and the door handles, as well as the personal protection of the relevant practitioners. Excluding dangerous chemicals, food, feed and feed additives and other commodities not suitable for the implementation of disinfection, as well as commodities without external packaging or external packaging is easy to cause the penetration of disinfection solution.
Two, the basic principles
According to the characteristics of the disinfection object, choose a safe and effective disinfectant, and use spraying or wiping and other methods of preventive disinfection. When the conventional disinfection method cannot be operated under special environment such as low temperature, effective low-temperature disinfection technology should be adopted, and the disinfection effect must be confirmed.
Disinfection process should pay attention to quality control to ensure the effect of disinfection. Disinfection operations, disinfection work should be recorded in detail, including the date, location, disinfection object, disinfectant name, concentration and duration of action, disinfection equipment, disinfection method, disinfection operator, etc., if necessary, disinfection effect evaluation, relevant information and records should be retained for at least 2 years.
In principle, only one preventive disinfection should be carried out on the outer surface of imported high-risk non-cold chain containers and cargo packages, to avoid repeated disinfection, to avoid increasing unnecessary operation links and costs, and to affect logistics and market supply.
The management of operators should be strengthened, and operators should do a good job of personal protection.
Three, disinfection methods
Normal temperature disinfection methods.
1. Container. Container walls can be used for effective chlorine 500mg / L of chlorine disinfectant, 0.1% to 0.2% of peroxyacetic acid or other effective disinfectant can be used for object surface disinfection spray disinfection. Disinfection should ensure that the container walls are covered with disinfectant, disinfectant dosage of about 200mL / m2 ~ 300mL / m2, to achieve the disinfection effect of time before the next operation. Disinfection of the inner wall of the container shall be carried out in accordance with the relevant provisions of the Civil Aviation Administration of China.
2. The surface of the outer package of the goods. Chlorine disinfectant with effective chlorine 500mg/L, 0.1%-0.2% peroxyacetic acid or other effective disinfectants that can be used on the surface of the object can be used to disinfect by spraying or wiping. Disinfection of the surface of the outer packaging of goods should ensure that the six sides of the outer packaging disinfection, leaving no dead ends, disinfectant dosage of about 200mL / m2 ~ 300mL / m2, to achieve the disinfection effect of time before handling, loading and unloading and other operations.
Low-temperature disinfection method.
In the low-temperature environment, the above conventional disinfection methods can not be operated, should be used for effective low-temperature disinfection methods for disinfection. Can be used to reduce the freezing point of the method to ensure that the disinfectant does not freeze, spray or wipe disinfection at low temperatures; or low-temperature disinfection equipment for disinfection. All low-temperature disinfection methods must be in the corresponding low-temperature conditions to confirm the disinfection effect.
Four, personal protection
