A vent-limiting orifice is only allowed to approximately discharge how much gas in a 24-hour period?

1 cubic foot
10 cubic feet
20 cubic feet
24 cubic feet

The correct answer is: 24 cubic feet

A vent-limiting orifice is designed to mitigate the potential hazards associated with the uncontrolled release of gas, particularly in situations where the gas supply may not be secure. The allowable discharge of around 24 cubic feet of gas in a 24-hour period is a specified limit that ensures safety while also permitting a manageable amount of gas to escape in case of a system failure or malfunction. This limit is set to prevent excessive gas accumulation, which could pose a risk of explosion or fire if not properly controlled. Setting the orifice discharge rate at 24 cubic feet strikes a balance between maintaining safety standards and allowing for potential operational variances. Higher discharge rates would increase the risk of gas buildup, while lower rates might not sufficiently mitigate risk in all scenarios. Overall, the specification aligns with best practices and safety regulations in gas fitting and venting systems.
