Respiratory protective equipment selection general principles

In the absence of a correct judgment of the nature of the pollutants in the operating environment, whether the concentration of pollutants is higher than the relevant standards and whether the operating environment is deficient in oxygen, improper respiratory protection equipment is selected to perform the operation, resulting in accidents.
Respiratory protective equipment is generally divided into filter type and isolation type. There are strict differences in the use of the operating environment. Correct selection of respiratory protection products is the first step in our work to effectively protect ourselves.
Respiratory protective equipment selection general principles:
Without protection, no one should be exposed to an air environment that can or may harm health.
1. According to the relevant national occupational health standards, the air environment in the operation shall be evaluated to identify the nature of the harmful environment and determine the degree of damage. 2. Respirators that are recognized by the country and meet the requirements of the standard shall be selected.
3. When selecting respiratory protective equipment, reference should be made to the technical specifications of its instructions for use and to the conditions of its use.
The correct choice of respiratory protective equipment should also be based on the toxic and harmful environment, the type of pollutants, the concentration of pollutants, the operating conditions, the characteristics of the laborers' head and face, and the physical conditions of the laborers.
Due to the wide variety of respiratory protective equipment and the different operating conditions and physical conditions of the operators, it is difficult to determine the contraindications for the use of respiratory protective equipment. It is necessary to make judgments in light of the actual situation in each area. Although many people are physically weak, they can safely use respiratory protective equipment as long as they can control the intensity of work and have enough rest time. Only by having a clear understanding of the nature of respiratory protective equipment, can we choose the right one, so that we can truly protect ourselves and avoid the occurrence of major casualty accidents.
