Respiratory Protection is in the highest class for personal protective equipment. The air we breathe must be as clean as possible. Even the smallest dust particles can cause considerable damage. Think of the danger of asbestos. Furthermore gases and vapours in the environment are serious risks to health. If insufficient measures are taken, acute poisoning can occur in the short term and a serious disease in the long run. The presence of hazardous substances in the air is therefore seen as a big risk.
That is why all respiratory protection products from VWR are classified in the PPE-class 3, the class with the greatest risk.
