Maryland lawmakers push for stricter safety standards on corrugated stainless steel tubing after fatalities

Maryland lawmakers are taking significant steps to enhance safety standards for corrugated stainless steel tubing (CSST) used in gas piping systems, following a series of tragic incidents linked to its failure during lightning strikes. During a recent Environment and Transportation Committee session, Delegate Dana Stein presented House Bill 222, which aims to require CSST that can withstand 36 coulombs of electrical arcing, a substantial increase from the current standard of less than 5 coulombs.

The urgency for this legislation stems from alarming statistics: since 2018, Maryland has recorded three fatalities, including two firefighters, due to CSST failures caused by lightning. Delegate Stein emphasized the need for stronger regulations, noting that while arc-resistant CSST was mandated in 2022, it remains vulnerable to lightning strikes. The proposed bill, if passed, would not take effect until October 2027, allowing manufacturers time to adapt to the new requirements.

Frederick County Executive Jessica Fitzwater and Sarah Laird, widow of Battalion Chief Josh Laird who died in a CSST-related fire, also voiced their support for the bill. Fitzwater highlighted the inadequacy of current testing standards, while Laird shared her personal loss and the ongoing risks posed by CSST failures. She noted that since her husband's death, there have been at least 30 documented CSST lightning fires in Maryland, underscoring the need for improved safety measures.

Michael Fleming, Chief Plumbing and Gas Inspector for Frederick County, added that the existing standards do not adequately protect consumers, as CSST can still be purchased and installed by unlicensed individuals. He urged the committee to pass the bill to prevent further tragedies and ensure public safety.

The committee's discussions reflect a growing recognition of the risks associated with CSST and the need for legislative action to protect Maryland residents and first responders. As the bill moves forward, stakeholders are hopeful that it will lead to safer homes and communities across the state.
