Disinfection is a very professional operation. In daily life, many people do not have relevant professional knowledge. Once the operation is improper, it will have adverse effects. Next, let's take stock of the nine common mistakes in using disinfectants at home~

In daily life, is the more frequent disinfection, the better the degree of sanitation?

Answer: wrong. In daily life, except for the specific pathogen pollution or the high incidence season of various infectious diseases, it is usually not necessary to carry out frequent disinfection, just do a good job in daily cleaning.

02 in order to achieve better disinfection effect, should the concentration of disinfectant be as high as possible?

Answer: wrong. Disinfectants are chemical agents, which usually have some side effects. When choosing the concentration of disinfectant, the corrosiveness and side effects of disinfectant should be fully considered while ensuring the disinfection effect.

Is your disinfectant effective?

Answer: wrong, in fact, the more expensive disinfectants available in the market are relatively less corrosive, sensitizing and side effects, and have better affinity with the surface of the object to be disinfected. Although the disinfection effect is not strong, it can meet the needs of most household disinfection.

Most of the more expensive disinfectants are compound quaternary ammonium salt disinfectants, which are not necessary for families.

Common disinfectants are:

Chlorine disinfectant (84 disinfectant), bromine disinfectant (dibromohyne), chlorine dioxide disinfectant tablet, quaternary ammonium salt disinfectant, 70-80% ethanol (alcohol). They can disinfect the tabletop, floor, sanitary ware and other surfaces of the family. Among them, chlorine containing disinfectant (84 disinfectant), bromine containing disinfectant (dibromohyne) and chlorine dioxide disinfectant tablet are highly effective disinfectants, which have certain corrosiveness and bleachability. It is not recommended to use them for disinfection of non-ferrous textiles and metal appliances.

Quaternary ammonium salt disinfectant and 70-80% ethanol (alcohol) are medium and low efficiency disinfectants with low skin irritation, but they can not kill the resistant viruses such as hand foot mouth disease enterovirus and norovirus in a short time.

matters needing attention:

● wear gloves when preparing disinfectant and disinfecting, and pay attention to protect yourself from being corroded by disinfectant.

The disinfectant is now used and prepared, and it is easy to fail after long-term use.

● dry bleaching powder and bleaching powder emulsion should not be poured into the sewer after disinfection to prevent sediment blockage.

● the disinfectant shall be wiped again with clear water after use to remove the residual disinfectant on the surface and avoid skin irritation.

● disinfectants should be kept in a dry, dark and ventilated environment, and children should not be exposed to them.

There is no mention of toilet cleaning in the table above. Is it not a disinfectant?

Answer: Yes, the main component of CLP is acids (slow-release organic acid preparation or liquid fast detergent mainly composed of hydrochloric acid), which can effectively remove alkali scale and have certain bactericidal function, but it is not a disinfectant.

Clean toilet clean cannot be mixed with other disinfectants. Once mixed, it is easy to cause disinfectant activation or chemical reaction to produce harmful gases. For example, clean toilet clean and 84 disinfectant will react rapidly to produce irritating toxic gas chlorine, which will cause damage to human body and even endanger life.

Is cleaning and disinfection one thing?

Answer: No, the focus of cleaning is to remove visible dirt and some bacteria; the focus of disinfection is to kill pathogenic microorganisms.

06 will cleaning agent and disinfectant work better together?

Answer: wrong. Most disinfection methods will be interfered by organic matters to some extent. Therefore, before disinfection, cleaning agent will be used for thorough cleaning to remove the visible dirt, so as to ensure the disinfection effect. However, it is not the detergent and disinfectant used together, it will achieve better results.

Most cleaning agents are ionic surfactants. If they are used together with disinfectants, they will react to reduce their effectiveness and even produce harmful gases. Therefore, they cannot be used together. Of course, except for cleaning disinfectant products on the market.

In order to ensure the quality of disinfection, should it be cleaned first and then disinfected?

Answer: not entirely. In most cases, in order to ensure the quality of disinfection, it is necessary to clean before disinfection. But if the contamination is very serious, such as human infection of H7N9 virus and Vibrio cholerae, in order to ensure the safety of operators, advanced disinfection and harmless treatment should be progressied, and then cleaned and sterilized.

In the winter and spring of 2008, the incidence of respiratory infectious diseases is high. Can families use disinfectants to disinfect the air?

Answer: air disinfection is a highly professional disinfection operation. During disinfection, it should be ensured that the disinfection factor emitted from the sterilizer / machine can reach the form of aerosol (or gas), i.e. the disinfection factor is in the state of suspended in the air for a long time (> 20 minutes), making the disinfection factor fully contact with all kinds of pathogenic microorganisms suspended in the air, so as to kill all kinds of pathogenic microorganisms The effect of pathogenic microorganisms.

Therefore, air disinfection using disinfectant spray method is not feasible, ordinary sprayers are not suitable for air disinfection, special equipment should be used for ultra-low volume spray disinfection, that is, most of the disinfectant sprayed out of the particle size is less than 50 m, and the general home can not be carried out. The purpose can be achieved by opening a window for ventilation or using a circulating air disinfector.

09: can silverware be tested or disinfected?

Answer: because silver can react with arsenide, people think it can test poison, but only arsenide.

Silver alloy material has the function of auxiliary antibacterial and bacteriostatic, but silver ware, silver containing material and silver ion preparation can not be used as disinfectant.
