In general, respiratory trauma is not obvious. Symptoms can appear after a while, even, for example, when a person has already reached retirement age. Therefore, it is important that all employees of specialized enterprises associated with the danger of respiratory damage can regularly use the appropriate respiratory protection. All of these PPE must meet generally accepted international standards and be suitable for each employee individually.

Respiratory PPE helps prevent poisoning that occurs in the workplace. They are especially relevant among builders, metallurgists, gas workers and representatives of professions associated with an increased concentration of harmful substances and dust. To choose such devices correctly, you should take into account the following nuances:
- Nature, character, degree of danger;
- Chemical and physical properties of air pollution;
- Concentration of harmful substances;
- Permissible level of concentration of pollutants;
- The period of use of PPE;
- Labor activity of employees, its conditions and the possibility of stress, both physical and psychological;
- Functionality and limitations of PPE.
Isolating and filtering PPE for respiratory organs
In a manufacturing plant where hazardous substances are regularly disposed of, respiratory protection devices are required. They are divided into insulating and filtering . Insulating products help to protect the worker when there is a deficiency of CO2 in the room, and in the air there are toxic substances exceeding the norm. Filtering devices are used if the oxygen composition is normal and the concentration of hazardous substances is limited.
Filtering PPE clean the incoming air from unnecessary impurities. As a result, clean air goes to the respiratory organs. Waste mixtures are discharged from the appliance. Such devices are divided into respirators and gas masks . It is advisable to use them when there is sufficient oxygen in the working room.
Filtering PPE is distinguished by a special design, which has a face that fits tightly to the respiratory organs. The main characteristic of such devices is the high degree of protection of the device. It denotes the rate of decrease in the concentration of the corresponding chemical impurities.
Respirators are divided into two types: filtering devices and mouth
