What is ventilation classified as in terms of hazard control strategy?

Ventilation is classified as an engineering control because it involves modifying the work environment to reduce or eliminate exposure to airborne contaminants or hazardous substances. Engineering controls are designed to create safer working conditions through physical changes to the workplace or the use of technology.

In the case of ventilation, it helps to remove harmful substances from the air, dilute them to safer levels, or provide fresh air to dilute pollutants. This is a proactive measure that directly addresses the source of the hazard rather than relying on human behavior or administrative procedures, which are associated with administrative controls.

Ventilation systems can be designed and installed based on specific hazards present in a workplace, making them effective and efficient at maintaining air quality and protecting the health and safety of workers.
