What do machinery rooms help protect building occupants from?

Machinery rooms are specifically designed to house mechanical equipment such as HVAC systems, boilers, and chillers, and they play a critical role in protecting building occupants from exposure to refrigerants. Refrigerants are substances used in cooling systems, and their leaks can pose serious health risks. By isolating this equipment in dedicated machinery rooms, the potential for harmful exposure to these chemicals is significantly reduced.

Machinery rooms are typically sealed and ventilated separately, ensuring that any possible leaks or issues do not directly impact the building's living or working spaces. This containment strategy helps minimize risks associated with refrigerants, which can be toxic and pose safety hazards to humans. This focus on safety and environmental health is a key aspect of mechanical system design and compliance with building codes.
