What is the minimum clearance that must be maintained in the fencing of compression equipment and dispensing systems?

The minimum clearance that must be maintained in the fencing of compression equipment and dispensing systems is essential for safety and accessibility. This clearance is critical to ensure that there is sufficient space for personnel to operate safely and to allow for emergency response if necessary. Additionally, maintaining the specified clearance helps prevent accidental contact with the equipment, which can pose significant risks.

A clearance of 2 feet is recognized as an adequate distance to provide both the necessary physical separation between the equipment and any surrounding obstacles while also ensuring that the area remains accessible for maintenance or operational activities. This standard is generally established based on industry guidelines to enhance safety in environments where compressed natural gas operations take place.

In contrast, the other options specify distances that are greater than what is mandated, which may be impractical in certain installations or exceed the necessary spacing to ensure safety and operational efficiency. Therefore, the specified 2 feet clearance is both sufficient and compliant with established safety practices.
