Ozone gas-generator rooms must be ventilated to achieve how many air changes per hour for safety?

The correct answer is based on safety standards regarding the ventilation of ozone gas generator rooms. Ozone is a potent oxidizing agent and can be harmful to both humans and materials due to its high reactivity. To ensure a safe working environment, it is recommended that ozone generator rooms achieve a minimum of six air changes per hour. This ventilation rate helps to dilute any ozone gas that might escape into the area, thereby reducing the potential for harmful exposure.

Maintaining this level of air changes is essential for controlling ozone concentrations within acceptable limits set by health and safety regulations. Effective ventilation can significantly reduce the risk associated with ozone and enhance overall air quality for personnel working in or near these environments.

Higher rates of air changes, like ten, twelve, or eight, may be beneficial in specific cases, but the standard minimum accepted level for general safety is established at six air changes per hour, making it the most appropriate choice in this context.
