What is the minimum clearance required for commercial clothes dryer exhaust duct to combustible materials?

The minimum clearance required for commercial clothes dryer exhaust duct to combustible materials is 6 inches. This requirement is established to ensure safety by preventing the risk of fire. Clothes dryer exhaust ducts can become quite hot during operation, and maintaining a clearance distance of 6 inches provides an adequate buffer that helps mitigate the potential for heat transfer to nearby combustible materials.

This standard is part of the larger goal of ensuring that mechanical systems operate safely in commercial settings, where the risk of fire can be heightened due to increased usage and the presence of more complex systems. By adhering to this clearance requirement, installers and operators can reduce the likelihood of accidents and enhance the overall safety of the facility.
