What is the recommended clearance for vent hoods above public walkways?

The recommended clearance for vent hoods above public walkways is 7 feet. This height is established to ensure safety and accessibility for the public. By maintaining a minimum clearance of 7 feet, this specification helps to prevent accidental contact with the vent hoods, which might be hazardous if they are positioned too low. This requirement is particularly important in areas where people frequently walk, to avoid any potential injuries or obstructions.

Choosing a height that is lower than 7 feet could compromise safety, making it more susceptible to interference from pedestrians and possibly leading to accidents. Ensuring that vent hoods are well above the average human height contributes to a safer public environment.
