Different respiratory PPE based on specific work situations.
Dust mask: A plumber working at a site with normal levels of dust and small particles should wear a dust mask to protect against inhaling these particles.
Oxygen respirator: In situations where there are vapors present, like a pipe fitter working for an extended period in a confined space with exposure to vapors, an oxygen respirator is necessary for breathing.
Positive-pressure mask: For a plumber inspecting the interior of a large-diameter pipe, a positive-pressure mask that maintains a higher pressure inside is suitable for protection.
