The ambient air present in some workplaces can directly affect the health of workers who face it. The use of chemicals or confined space work are just a few examples of situations that can expose them to different contaminants potentially present in the ambient air of the workplace.
These contaminants can be found in the form of particles, aerosols, gases, smoke, or steam. It is therefore essential to know the products used and their volatility in the air to be able to choose an appropriate respiratory protection.
