Teach you to choose the best respiratory protection

Safety Protection Respiratory protection products on the market can be described as diverse, and for the correct choice of respiratory protection products, we need more thinking. Below, Luzhou Haigu Safety Protection Technology Co., Ltd. introduces you to how to choose the best respiratory protection products.

The effectiveness of respiratory protective equipment is mainly reflected in two aspects: the ability of respiratory protective equipment to provide clean air for breathing, and the ability to isolate clean air from the mask and air pollution from the outside of the mask.

When choosing safety products, we must consider the latter seriously. Therefore, we need to rely on the closeness of the protective mask to the user's face. An effective method for judging closeness is suitability testing. The so-called suitability test is not simply to check the performance of the respiratory protection mask, but to check the closeness of the mask with each specific user's face. In general, we need to carry out the inspection of the adhesiveness of the mask according to the standard during the inspection and certification of the respiratory protective mask. When choosing a mask, first select a rough face based on the face size provided by each face mask, and then confirm that it can be closed with the suitability test.

The suitability test requires the use of certain reagents (such as particles or gases) to determine whether the mask can reduce the concentration of the reagent outside the mask by detecting or detecting the concentration of the mask inside and outside. Taking the qualitative suitability test as an example, with the aid of a spray device, a special proportioning such as saccharin (sweetness) or a bitter agent liquid spray is sprayed on the premise of confirming that the user can taste the agent, relying on the taste of the user to inspect the spray. ,Judge whether the mask can taste the spray, if you can not taste it, you can generally judge the closeness of the mask is better. If the user can taste the taste in the suitability test, there are two possibilities. One is that the mask type is not suitable, and the other is that the mask is worn or adjusted improperly. Therefore, a second chance is provided for each failed test, and the test is repeated by adjusting the elasticity of the headband, the position of the mask, and the elasticity of the nose clip. If there is still taste, the user should choose another model or brand of protective mask. Qualitative fitness testing equipment is relatively simple and easy to implement. For situations where a full face mask is required, the suitability of the mask needs to be determined by a quantitative suitability test. It is advisable to contact the mask supplier to provide the relevant service. The suitability test should be performed when the respiratory protection mask is used for the first time, and once a year thereafter, suitability testing should be provided by the unit providing respiratory protection products.

Zhuozhou Haigu safety protection experts introduced: Each suitability test has applicability and limitations, general qualitative suitability test can only be suitable for half masks, or the environment where the concentration of protection pests does not exceed 10 times the exposure limit, quantitatively suitable Sex tests are suitable for all types of masks. For a filter-type respirator, mask types and appropriate filter elements should be selected according to the type, characteristics and concentration of harmful substances on the site. When the type of harmful substance is unknown or not alert or the warning is poor, and there is no suitable filter element, filter respiratory protection cannot be selected.

In general, anti-particulate filter elements should be used for microbiological, radioactive and nuclear explosives (nuclear dust), as well as general dust, smoke, and fog. However, it is necessary to distinguish between the level of filtration efficiency and the type of filter element, and the selection of filtration efficiency. The principle is that carcinogenicity, radioactive and highly toxic particulates should be selected with the highest efficiency. Microorganisms should at least choose the efficiency at 95%, and the principle of category selection is: if it is oily particulate matter (such as oil mist, asphalt fume, some high-boiling organics The release of toxic agents produces oily particles, etc.) Oil-resistant filter elements should be selected. If the particulate matter is also volatile, it must also be equipped with a filter element that protects the corresponding gas.

The best way to pick the best respiratory protection products for suitability testing is the detailed introduction of Haigu experts who will teach you to choose the best respiratory protection products and hope to help you.
