Choice of respiratory protective equipment
       Respiratory Protection 

       Occupational hazards of breathing class is known as the "invisible killer", caused due to long-term inhalation of dust pneumoconiosis has accounted for about 80% of all occupational. Workers are still often see wrong with gauze masks to the protection of respirable dust. Some potentially toxic gases will lead to a more serious injury, even death. Breathing like a wide range of PPE products, how to choose the right product according to the degree of respiratory hazards, became breathe a required course of self-protection. 

       Need to be equipped to assess whether respiratory protection products, you should first confirm the following points: 
       1, the working environment is a confined space, the oxygen concentration of the air is lower than 19.5%, the guarantor of the concentration has been unable to breathe properly. 
       2, the air in the unknown, odorless, poisonous gas? 
       If there are more than risk, must be equipped with active oxygen system, to guarantee job security. 

       Above may exclude, and then detect toxic and harmful gas dust concentration level (OEL), lower than the value of the level prescribed by the State, you do not need to use any masks or masks, if higher than the level of provisions, you will need to select the appropriate respiratory protection products, the vast majority of respiratory protection products in this range assessment selection. 

       The need to use respiratory protection, hazardous air environment can be divided into the following categories, a different environment need to use a different product: 
       Dust (including solid and liquid particles and microorganisms) 
       Toxic gases 
       There are dust and toxic gases 

       Dust masks and filters need to use to filter the air. 
       The dust can be divided into two categories: non-oily dust and oily dust, general coal dust, cement dust, cotton dust, mist, paint fog belong to the non-oily dust, fumes, oil mist, asphalt smoke, coke oven smoke. Diesel exhaust and other oily dust. 

       Non-oily dust and oily dust protection need to use different materials, non-oily dust protection in general non-woven materials are based on electrostatic adsorption filtration of dust particles to purify role. But for oily dust particles, these substances would reduce power attached to the electrostatic nonwoven fabric, so that the fine dust penetration, anti-oil aerosol filter after a special treatment in order to achieve the purpose of the anti-small dust. 

       Toxic gas protection, general use of gas masks, one of the most critical is the selection of cartridges, the working environment of toxic gases following categories: organic gases, acid gases, organic / acidic gas, ammonia and derivatives mercury vapor and chlorine gas mixture, the major manufacturers have a corresponding Cartridges for the work environment, and marked in different colors to distinguish. As long as we can shining select. 

       Dust poison mixed environment generally use the principle of combining cotton filter and cartridges fitted cotton filter in front of the cartridges, the first cotton filter air medium dust filter, then the poison gas filter cartridges This can effectively protect employees working in the the dust toxic gas mixed environment. 
       For only a trace of poison gas, the working environment, some manufacturers developed activated carbon masks, organic vapor odor and acid gas odor respirator protection dust protection part of the toxic trace gas. 

       Esen PPE engineers will work with you, assess all the risks faced by your workshop. And listen to the other requirements of the first-line operators outside for security, to provide you with the most complete solutions respiratory protective equipment.
