Corrugated Stainless Steel Tubing – or CSST – is a flexible yellow pipe used to provide natural gas and propane to many homes and businesses. If you live or work in a structure built between 1990 and 2006, or if gas line work was performed on your building during that period, be aware of possible safety hazards associated with CSST. Get educated now to ensure your home or building is protected.

CSST safety facts

1. Many CSST pipe systems are not installed to current model code requirements.

Some 500,000 new homes in the United States have CSST installed each year. But since regulations directing how pipes are bonded and grounded were not adopted until 2006, it’s smart to have your piping system inspected by a licensed electrician.

2. Properly bonding and grounding a CSST gas line system is critical.

Direct bonding better secures electrical continuity and conductivity through metal pipes, while grounding can send any lightning strike into the ground. CSST systems installed before the bonding/grounding rules are susceptible to lightning strikes, which can cause electrical shocks.

Direct bonding on your natural gas system reduces the chances of electrical shock, as well as a natural gas leak or fire.

3. CSST piping can be damaged by lightning.

Lightning striking a CSST gas line system can be extremely dangerous. A strike on or near a building can travel through the structure’s piping system and cause a damaging power surge that can produce a gas leak or fire.
