Respiratory protection equipment ensures that you breathe clean air while also protecting you from dangerous gases or airborne particles. Airline filtration and CO monitors remove pollutants from the air supply and measure gas concentrations. In emergency scenarios and dusty work environments, disposable respirators and dust masks keep airborne particles out. Emergency escape breathing apparatus and escape hoods protect people from toxic air for a brief period of time, allowing them to flee a dangerous situation. Fit-testing equipment checks if a respirator fits the wearer adequately. Respirators and gas masks function with filtering cartridges to give clean air when working in potentially dangerous settings. SCBA (self-contained breathing apparatus) pulls high-quality breathable air from a compressed-air cylinder and delivers it to the attached face mask. PAPR (powered air purifying respirator) draws in ambient air and filters it before blowing it into the attached face mask.
