What type of system must be provided and operated in areas with irritating or health-hazardous contaminants?

In areas where there are irritating or health-hazardous contaminants, it is essential to use an exhaust system. An exhaust system is designed specifically to remove contaminated air from a space and replace it with cleaner air from outside. This is critical in maintaining air quality and ensuring the health and safety of occupants.

The primary function of an exhaust system is to capture and vent hazardous fumes, vapors, or particulate matter directly outside, preventing them from accumulating in occupied spaces. This type of system is particularly important in industrial settings, laboratories, or any area where harmful substances are produced or used. By effectively removing contaminants at their source, exhaust systems help to minimize the risk of exposure and related health issues.

While filtration, ventilation, and heating systems play significant roles in overall air quality and comfort, they do not specifically address the need to eliminate or mitigate harmful contaminants as effectively as an exhaust system. Filtration systems are excellent for purifying air but primarily function by trapping particles rather than removing stale, contaminated air. Ventilation systems help to circulate air and can reduce contaminants, but they do not always guarantee the removal of harmful gases or fumes from the space. Heating systems, focusing on temperature control, do not provide any direct removal of contaminants. Thus, in environments with
