True or False: Air vent rates can be used if occupants are on a bibs system, even while breathing oxygen.

Air vent rates play a crucial role in maintaining the quality of breathable air within a confined space, especially when occupants are utilizing a bibs system that delivers oxygen. Using air vent rates in conjunction with a bibs system ensures that there is an adequate supply of fresh air to dilute any potential contaminants while the system is operational, thus providing a safer environment for users.

When occupants are on a bibs system, they are receiving a concentrated source of oxygen, which might lead to an altered air quality requirement. However, implementing air vent rates is still essential to prevent the build-up of carbon dioxide and other gases that might be present, ensuring that the conditions remain safe and breathable. Thus, it is accurate to say that air vent rates can indeed be used in this context, as they enhance safety and ventilation even when occupants are breathing supplemental oxygen.

Other options suggest limitations or specific circumstances that would apply to the use of air vent rates. However, the assertion that they can be utilized without these constraints is supported by practices aimed at ensuring proper air quality, regardless of the oxygen delivery method.
