What type of barriers must protect appliances that are subject to mechanical damage?

Appliances that can be exposed to mechanical damage must be protected by approved barriers to ensure their safe operation and longevity. Approved barriers are designed to withstand impacts and shield the equipment from potential harm caused by external forces, such as accidental contact or falling objects. This protection is particularly vital in settings like commercial kitchens or mechanical rooms, where appliances are often in high-traffic areas or are subjected to rough handling. The use of barriers enhances safety by preventing damage that could compromise the performance of the appliances or create hazardous situations.

Other types of barriers, like temporary or flexible barriers, may not meet the necessary safety and durability standards required by the code. They might not provide adequate protection over time or in various situations, making them unsuitable for the intended purpose. Therefore, it is essential that the barriers used are specifically approved and meet the relevant regulations outlined in the North Carolina Mechanical Code.
