What is required for corrugated stainless steel tubing (CSST) gas piping that is not listed as arc-resistant?

For corrugated stainless steel tubing (CSST) gas piping that is not listed as arc-resistant, bonding is required to ensure the safety and integrity of the gas piping system. Bonding involves connecting the CSST to a grounding system to protect against electrical faults and ensure that any electrical currents have a low-resistance path to the ground. This is critical because it helps to prevent potential electrical arcing, which could lead to fire hazards or explosions.

Bonding acts as a safety measure to mitigate the risks associated with stray electrical currents that can affect the CSST, especially in homes or buildings where electrical interference is present. Proper bonding ensures that both the gas piping and any attached appliances maintain a consistent electrical potential and reduces the likelihood of dangerous arcing events.

The other options, such as coating or insulating, while relevant in their own right, do not serve the same purpose as bonding in preventing electrical hazards associated with CSST piping. Grounding, while often confused with bonding, refers specifically to connecting an electrical system to the earth to dissipate electrical energy, which, although important, does not replace the need for bonding in this context.
