MODERATE

The bill was finalized into its enrolled version, adding formal signatures and proofreading details required for Governor approval.

The bill's scope was expanded to explicitly include 'gas piping' alongside corrugated stainless steel tubing in the study requirements and prohibitions.

REQUIREMENT

The prohibited tubing specification was updated to explicitly include 'non-arc-resistant' tubing, clarifying the safety standard beyond just nonconductive materials.

The study mandate was broadened to include 'gas piping' systems and an analysis of fire risks from lightning strikes.

The study's purpose was clarified to specifically address preventing fire hazards associated with commonly used fuel gas piping systems in residential and commercial buildings.

The study scope was updated to analyze the effectiveness of existing standards and identify areas for improvement.
