What it does
This bill prohibits lawsuits against manufacturers and sellers of stone slab products (like quartz countertops) for injuries workers suffer from silica dust exposure during fabrication—even if the product itself is safe when sold. The bill shields manufacturers and sellers from liability for harm caused by third-party fabricators' failure to follow workplace safety rules, and requires dismissal of all pending cases.
Why we flagged it
The bill's operative mechanism is a blanket immunity for stone slab manufacturers and sellers from civil liability for workplace injuries caused during product fabrication, regardless of product design or warnings. This is a classic liability carve-out, not a safety or consumer-protection measure.
What the text implies
- Workers injured by silica dust may have no solvent defendant to sue: fabricators are often small, undercapitalized shops; manufacturers remain wealthy and judgment-proof to injured workers.
- The bill does not require manufacturers to design safer products, provide warnings, or improve product safety—it only shields them from liability for harm caused by others' non-compliance with existing OSHA rules.
- State tort law is preempted for an entire product category and injury type, centralizing immunity in federal law and removing a traditional check on manufacturer accountability.
- Fabricators face full liability exposure even when manufacturers could have engineered safer products or provided better guidance on safe handling.
- The bill's framing of lawsuits as 'frivolous' and a 'burden on commerce' may discourage injured workers from pursuing claims even against fabricators, due to chilling effect and reduced legal resources.

Who it affects
Workers injured by silica dust during stone slab fabrication lose their right to sue manufacturers and sellers, even when those companies could have designed safer products or warned of risks. The bill transfers all liability to fabricators (often small shops with limited assets) while shielding profitable manufacturers from accountability, leaving injured workers with fewer recovery options.
Who stands to gain
- Stone slab manufacturers (quartz, engineered stone producers)
- Stone slab importers and distributors
- Retailers and suppliers of stone slab products
Named in the bill
Manufacturers of stone slab products, Sellers and distributors of stone slab products, Fabricators (third-party cutters and installers), OSHA (Occupational Safety and Health Administration), California Labor Code, Federal courts, State courts
