What is the minimum height for guards mounted above a platform surface for roof-mounted equipment?

The minimum height for guards mounted above a platform surface for roof-mounted equipment is set at 42 inches. This standard height is established to ensure adequate protection against falls and to provide a safety barrier for workers who may be accessing the equipment on the roof.

Having guards at this height aligns with safety regulations and best practices, helping to prevent accidents by offering a physical barrier that is high enough to deter individuals from accidentally falling off the platform. The choice of 42 inches reflects a compromise that balances usability and safety, ensuring that the guards are tall enough for most individuals without being excessively obstructive.

Other heights like 36 inches, 48 inches, or 54 inches do not align with the established regulations and could present increased risks to safety. Guards that are too low may not provide the necessary protection, while those that are excessively high could make access to the equipment more difficult. Hence, 42 inches is deemed the most effective and compliant height for maintaining a safe working environment around roof-mounted equipment.
