What minimum clearance must be maintained between the railing and CNG compression equipment?

The correct answer, which indicates that a minimum clearance of 24 inches must be maintained between the railing and CNG compression equipment, is important for several safety and operational reasons.

Maintaining this specific clearance is crucial to ensure safe access for maintenance and emergency situations. A 24-inch gap helps prevent accidental contact with the compression equipment, which may be under high pressure and present safety risks. Additionally, this clearance allows for sufficient airflow around the equipment, mitigating the risk of overheating and ensuring that any potential gas leaks can dissipate safely without being trapped or accumulating near the equipment.

Furthermore, adhering to this standard can enhance the safety of personnel working nearby, providing them with a buffer zone to move safely around the equipment while reducing the chance of unintended interference. This standard is part of industry best practices and regulations set forth to minimize risks associated with compressed natural gas operations. Proper spacing also helps in compliance with relevant safety codes and standards, ensuring that facilities operate within legal parameters while safeguarding people and property.
