What is the minimum distance mechanical intakes must be from any potentially hazardous source?

The minimum distance that mechanical intakes must be from any potentially hazardous source is established to ensure the safety and efficiency of the HVAC system. This distance of 10 feet is crucial for preventing contamination of the air intake by harmful substances that may be released from sources such as vents, exhaust systems, or chemical storage areas.

Having intakes positioned too close to these potentially hazardous sources could lead to the introduction of harmful pollutants into the system, compromising indoor air quality and potentially leading to health risks for occupants. By maintaining a distance of 10 feet, the design effectively minimizes any negative impact on the air being circulated, ensuring cleaner and safer operation of the HVAC system.

This standard is often mandated in building codes or best practices within the HVAC industry, highlighting its importance in protecting both the functionality of the equipment and the well-being of individuals utilizing the building.
