What is one common method for reducing exposure to airborne contaminants?

Ventilation systems are a widely recognized method for reducing exposure to airborne contaminants. The primary function of ventilation is to introduce outdoor air into a workspace and remove indoor air, which can help dilute and disperse harmful airborne pollutants. This process improves overall air quality and lowers the concentrations of toxic substances, thereby protecting the health of employees who are working in environments where such contaminants may be present.

Effective ventilation systems can include general dilution ventilation, local exhaust ventilation, or a combination of both. General dilution ventilation works by mixing fresh air with contaminated air to lower pollutant levels throughout a facility. Local exhaust systems, on the other hand, capture contaminants at their source before they can disperse into the ambient environment.

This approach is crucial in many industries, particularly those involving chemicals, dust, fumes, and biological agents, as it addresses potential hazards directly related to the air quality within the workplace. By minimizing the presence of airborne contaminants, ventilation systems play a vital role in occupational health and safety programs.
