Proper ventilation is a critical method to prevent chemical exposure in a workplace because it helps to ensure that harmful vapors, fumes, or dust generated by chemicals are effectively diluted and removed from the air. Adequate ventilation systems, including exhaust fans, air filtration units, and natural airflow, work to maintain air quality by reducing the concentration of airborne contaminants, thereby protecting the health and safety of workers.

While regular inspections and training sessions play important roles in workplace safety by identifying potential hazards and educating employees about proper handling procedures, these measures do not directly eliminate the presence of harmful chemicals in the air. They serve to complement ventilation systems but do not replace them as the primary means of reducing exposure.

Strict attendance policies focus on attendance and do not relate to chemical safety. Therefore, they do not contribute to the reduction of chemical exposure in any meaningful way. Proper ventilation is essential for maintaining a safe environment in workplaces that deal with hazardous substances, making it the most effective and common method for preventing chemical exposure.
