What must be maintained in a hydrogen piping system if mechanical joints do not provide electrical continuity?

• A. Electrical isolation
• B. Grounding
• C. Electrical resistance
• D. Bonding jumper

Answer: (D)

In a hydrogen piping system, if mechanical joints do not provide electrical continuity, a bonding jumper must be maintained to ensure electrical continuity throughout the system. The purpose of a bonding jumper is to connect various sections of the piping together, thereby minimizing the potential difference between those sections and ensuring that they are at the same electrical potential. This is crucial in preventing the buildup of static electricity, which can lead to unsafe conditions, especially in systems handling flammable gases like hydrogen. When mechanical joints fail to provide electrical continuity, the risk of electric arc or sparking increases, which can be hazardous in environments where hydrogen is present. By using a bonding jumper, the integrity of the electrical pathway is preserved, allowing any stray static charge to be safely dissipated, thereby enhancing the overall safety and reliability of the piping system.
