On March 10, 2025, Maryland lawmakers introduced House Bill 222, a significant piece of legislation aimed at enhancing safety standards for fuel gas piping systems in buildings. The bill specifically targets the use of corrugated stainless steel tubing, a common material in gas piping, by establishing stringent requirements to ensure its reliability and safety.

The primary purpose of House Bill 222 is to mandate that any corrugated stainless steel tubing used in new constructions or major renovations must either meet the LC1027 standard outlined in the latest International Fuel and Gas Code or demonstrate the ability to withstand at least 36 coulombs of electrical arcing charge through a designated testing process. This move comes in response to growing concerns about the safety of gas piping systems, particularly in light of incidents involving gas leaks and explosions.

Key provisions of the bill stipulate that only compliant tubing can be utilized in new customer-owned natural gas or liquefied propane piping systems, as well as in significant renovations affecting over 50% of a property’s square footage. Violators of these regulations could face civil penalties of up to $1,000, underscoring the bill's emphasis on accountability and safety.

The introduction of House Bill 222 has sparked discussions among lawmakers and industry experts regarding its implications for public safety and construction practices. Proponents argue that the bill is a necessary step to prevent potential hazards associated with substandard materials, while critics express concerns about the financial burden it may impose on builders and property owners, particularly in the context of rising construction costs.

As the bill progresses through the legislative process, its potential impact on Maryland's construction industry and public safety remains a focal point of debate. If enacted, the law is set to take effect on October 1, 2027, giving stakeholders time to adapt to the new requirements.

In summary, House Bill 222 represents a proactive approach to ensuring the safety of fuel gas piping systems in Maryland, reflecting a commitment to protecting residents from the risks associated with inadequate materials. As discussions continue, the bill's fate will be closely watched by both supporters and opponents, highlighting the ongoing dialogue about safety standards in the construction industry.
