Respiratory protective equipment (RPE) is made to protect the wearer against the inhalation of airborne hazards in the work enviroment. Respiratory protection is very important and can help prevent many unwanted health complications. It should be used only if there is no other option. It is very important to fit test them and make sure there are no loose fittings and the equipment suits right. If used right they filter out the hazardous gases and vapors and provide clean air for the wearer.
