What must be provided where appliances and other components requiring service are located within 6 feet of a roof edge?

When appliances and other components requiring service are situated within 6 feet of a roof edge, guards must be installed to provide safety and prevent accidental falls. Guards serve as an important safety feature, ensuring that individuals working on or around these appliances are protected, reducing the risk of falls from the roof's edge. The presence of guards is in alignment with safety practices mandated by codes regarding working on elevated surfaces.

Fencing, signage, and barriers are generally not the primary solutions for addressing the immediate risk of falling from a height when servicing equipment located close to an edge. Fencing may restrict access but wouldn’t necessarily prevent someone from climbing over. Signage can warn individuals of potential dangers but does not offer physical protection. Barriers may provide some level of protection but are not as specifically defined in this context as guards are when it comes to maintaining safety standards around service locations close to roof edges.
