Questions: What is considered a best practice when a plece of equipment that uses compressed air is taken out of service? Check the equipment on a weekly basis to ensure there are no air leaks Shut off air flow to the equipment as far back in the distribution system as possible Install a flow meter in front of the out-of-service equipment to alert someone if too much air is flowing to the equipment Install a flow controller in advance of the out-of-service equipment to reduce pressure and minimize artificial demand

The answer is the second one: Shut off air flow to the equipment as far back in the distribution system as possible.

Explanation for each option:

• Check the equipment on a weekly basis to ensure there are no air leaks: While regular maintenance and checks for air leaks are important, this option does not directly address the best practice for taking equipment out of service. It is more of a general maintenance practice.

• Shut off air flow to the equipment as far back in the distribution system as possible: This is considered a best practice because it ensures that no compressed air is wasted on equipment that is not in use. By shutting off the air flow as far back as possible, you minimize the risk of leaks and unnecessary energy consumption.

• Install a flow meter in front of the out-of-service equipment to alert someone if too much air is flowing to the equipment: While installing a flow meter can be useful for monitoring air flow, it does not prevent air from reaching the out-of-service equipment. It is more of a monitoring tool rather than a preventive measure.

• Install a flow controller in advance of the out-of-service equipment to reduce pressure and minimize artificial demand: A flow controller can help manage air pressure and demand, but it does not address the fundamental issue of stopping air flow to equipment that is not in use. It is more of a control measure rather than a direct action to take equipment out of service.

In summary, the best practice when taking equipment out of service is to shut off the air flow as far back in the distribution system as possible to prevent unnecessary air usage and potential leaks.
