Information on barriers to using respirators for hazardous chemicals was also collected. A proper fit check is relatively simple: when inhaling, the respirator should collapse, and when exhaling there should be no leakage around the face. Filters cease to provide protection when saturated with hazardous chemicals, and degrade over time even if sealed. N95 respirators are of better quality and have a better fit and seal than basic surgical masks, thereby providingimproved prevention of aerosolized particle transmission. Some World War II and Soviet Cold War gas masks contained chrysotile asbestos or crocidolite asbestos in their filters,[2][3][4] not known to be harmful at the time. This is small com- pared to the overall cost of great ape tourism operations, although the reliability of supply chains has to be assured.

No. [6] Each filter type protects against a particular hazard and is color-coded: Particle filters are often included, because in many cases the hazardous materials are in the form of mist, which can be captured by the particle filter before entering the chemical adsorber.
