How far horizontal separation is required between ducts conveying explosive substances and exterior walls?

The requirement for horizontal separation between ducts that convey explosive substances and exterior walls is crucial for safety and compliance with established regulations. A horizontal separation of 6 feet is necessary to reduce the risk of fire or explosion hazards affecting adjacent structures. This distance helps to ensure that any potential leaks or unintended discharges from the ducts do not come into direct contact with the building, which could lead to catastrophic outcomes.

The specified distance serves multiple purposes: it minimizes the likelihood of hazardous materials reaching the exterior walls, allows for safer maintenance access, and provides a buffer zone that can protect the integrity of the building during emergency situations. Adhering to this standard is fundamental in drafting safe mechanical designs in environments where explosive substances are present, ensuring compliance with safety codes and contributing to the overall safety of the structure and its surroundings.
