Principles of cleaning: Continuity, cleaner production is not a once-and-for-all, but requires continuous improvement of products and processes.
Preventive, cleaner production emphasizes pollution-free reduction at the source during the product life cycle.
Comprehensive, cleaner production involves the regional economy, society, the environment and other aspects, is a systematic project in which the whole society should participate.
Principle of disinfection: to prevent pathogens from spreading into the society and causing epidemics to occur.
To prevent the sick from being infected by other pathogens, complications and cross-infection.
It also protects healthcare workers from infection. Sterilization alone is not enough to achieve these purposes. It must be accompanied by the necessary isolation measures and aseptic operation at work in order to achieve the effect of controlling the infection.
Different transmission mechanisms cause infectious diseases, the effect of disinfection is different. Gastrointestinal infectious diseases, pathogens with feces or vomit out of the body, the scope of contamination is more limited, such as timely and normal disinfection, cut off the transmission pathway, interrupt the spread of the effect is better.
Respiratory infectious diseases, pathogens with breathing, coughing, sneezing and discharged, and then through the droplets and dust and spread, the scope of contamination is not exact, disinfection is more difficult. Must be taken at the same time space isolation, in order to interrupt the transmission. Insect-borne infectious diseases, such as insecticide and rodent extermination methods.
Methods of cleaning: The implementation of cleaner production from the government's macroscopic point of view: the designation of special policies to encourage cleaner production, improve the existing environmental laws and policies to overcome obstacles, industrial and industry restructuring, and the arrangement of a variety of activities to raise public awareness of cleaner production.
Support industrial demonstration projects, provide technical support to the industrial sector, and incorporate cleaner production into school education at all levels.
Different infectious disease pathogens have their own characteristics and have different tolerances to different disinfection methods. For example, bacterial germ cells have the strongest tolerance to various disinfection measures, and must be treated with sterilizing agents with strong bactericidal power, heat or radiation to achieve better results.
Therefore, it is generally taken as a representative of the most difficult to disinfect. Others, such as Mycobacterium tuberculosis, are sensitive to heat sterilization, but are more resistant to general disinfectants than other bacteria. Fungal spores are very resistant to ultraviolet light, but are more easily killed by ionizing radiation. Enteroviruses have a similar tolerance to peroxyacetic acid as bacterial propagules, but quaternary salts are ineffective against them.
Botulinum toxin is readily destroyed by bases but is highly resistant to acids. As for other bacterial propagules and viruses, spirochetes, mycoplasma, chlamydia, rickettsiae are poorly tolerant of general disinfection. Common disinfection methods can generally achieve good results.
Extended information:
Hospital disinfection system: medical personnel must comply with the principle of disinfection and sterilization, into the human body tissue or sterile organs of the medical supplies must be sterilized, contact with the Instruments and supplies that contact the skin and mucous membranes must be sterilized.
Disinfection of the first choice of physical methods, can not use physical methods of disinfection of the items before choosing chemical disinfection methods.
Used medical equipment and articles should be decontaminated first, thoroughly cleaned and then disinfected or sterilized. Non-infectious disease patients used instruments first with enzyme detergent soak scrub to remove dirt. The equipment and articles contaminated by Class A infectious patients and patients with hepatitis, tuberculosis, AIDS, anthrax or other infectious diseases should be sterilized and then cleaned.
According to the performance of the items and then according to the type of hazardous selection of disinfection and sterilization methods. Heat-resistant, moisture-resistant goods sterilization preferred physical sterilization method. Surgical instruments and articles, a variety of puncture needles, syringes and other preferred pressure steam sterilization. Dry heat sterilization is preferred for oils, powders and creams. Heat-resistant items: a variety of catheters, precision instruments, artificial grafts, etc., can choose to use chemical sterilization methods such as epoxy has been sterilized, low temperature plasma and so on.
The use of chemical methods for sterilization or disinfection. According to different situations to choose sterilization, high-efficiency, medium-effective, low-effective disinfectants. The use of chemical disinfectants must understand the performance of the disinfectant, the role of the disinfectant, the use of the factors affecting the sterilization or disinfection effect, the preparation of precautions and effective concentration. Regularly do the effective concentration test and the monitoring of disinfection and sterilization effect.
Obey the regulations and requirements of the unit and the project unit, and do the work in the area of responsibility in accordance with the operating procedures and cleaning standards. Responsible for the specific implementation of cleaning work, learning relevant business knowledge and skills, receive training, master the basic operating skills of cleaning tools.
Leaving the workstation for any reason to obtain the consent of the shift supervisor in advance, such as the superior to do the decision to have different opinions, should be completed before the discussion. Must be absolutely obedient to the shift supervisor's work transfer or arrangement;? Comply with the correct work procedures and methods, according to the amount of foot traffic at any time to do a good job of cleaning, and regularly patrol the key areas.
Strictly according to the corresponding operating procedures to use, storage, custody of cleaning equipment, facilities, damage or loss of timely report to the foreman for the record, the project manager in accordance with the relevant provisions of the treatment. Correct use of various cleaning agents, waste is strictly prohibited.
Actively participate in sanitation blitz work, such as: VIP visits, rain in front of the door, snow cleaning blitz work.
Promote hygiene knowledge to customers, discourage and stop unhygienic, uncivilized phenomena and behavior. Obligation to maintain the normal use of public **** facilities, equipment condition, in the cleaning process, such as found public **** facilities have been damaged, should be reported in a timely manner.
