What is the most common problems with negative pressure respirators?
What is the most common problems with negative pressure respirators? The main disadvantage of negative-pressure respirators is that if any leaks develop in the system (i.e., a crack in the hose or an ill fitting mask or facepiece), the user draws contaminated air into the facepiece during inhalation. What are the two main types of […]
