What is the height requirement for the passageway that provides access to appliances under floors?

The correct height requirement for passageways that provide access to appliances under floors is 22 inches. This standard ensures that technicians and service personnel can safely and comfortably access appliances that require maintenance or inspection. A passageway height of 22 inches is adequate for most situations, providing enough room for individuals to maneuver without risking injury or damaging equipment.

This requirement reflects the need for safety and accessibility in mechanical systems, facilitating easier serviceability while maintaining the integrity of the installation area. Standards like this are important for ensuring that mechanical systems are not only functional but also compliant with local codes, promoting overall safety in the building environment.
