At what distance from roof edges must guards be provided for appliances that require servicing?

Guards must be provided at a distance of 10 feet from roof edges for appliances that require servicing to ensure the safety of personnel during maintenance work. This requirement is based on the need to prevent falls and provide adequate protection while technicians access these appliances.

By mandating this distance, the code acknowledges the potential hazards associated with working near the edge of a roof and aims to minimize the risk of accidents. The 10-foot barrier serves as an effective precautionary measure, ensuring that workers have a safe working area that maintains a buffer from the dangers associated with falling off the roof or being close to the roof edge while performing maintenance tasks.

Understanding the importance of this requirement is crucial, as it reflects best practices in safety and compliance with local regulations in mechanical installations and maintenance operations.
