Ventilation in the workplace is used to control the work environment by doing what?

• A. Using PPE
• B. A method of controlling the work environment by supplying air or exhausting air
• C. Isolating hazard with barrier
• D. Substituting with a less hazardous chemical

Answer: (B)

Ventilation controls the work environment by moving air to dilute and remove airborne hazards. Supplying fresh air lowers the concentration of contaminants, while exhausting air removes contaminated air, heat, and odors. This can be done as general ventilation or local exhaust ventilation, making it an engineering control aimed at air quality and comfort. It’s distinct from relying on PPE, isolating hazards with barriers, or substituting with a less hazardous chemical, which are different approaches to protection.
