Understanding Manufacturing and Product Defects in California
- Last Updated:
What California Law Gives You After a Product Defect Injury at Work
When a defective product injures you on the job in California, workers’ compensation is usually the first step, but it is rarely your only option. Labor Code § 3852 allows you to file a separate civil lawsuit against any third-party manufacturer, supplier, or distributor whose defective product caused your injury, on top of your workers’ comp claim. And if your employer manufactured the defective product, sold it to someone else, and you encountered it as a consumer rather than as part of your job, Labor Code § 3602(b)(3) may let you sue your own employer in civil court. Workers who reported the defect and then faced retaliation are separately protected under Labor Code § 6310.
What California Law Required Before You Were Ever Injured
Every California employer has a pre-existing legal obligation to keep your workplace safe. Labor Code § 6400 requires every employer to furnish a place of employment that is safe and healthful, to eliminate recognized hazards, and to comply with all occupational safety and health standards under Cal/OSHA. This duty applies directly to defective machinery, tools, and equipment in manufacturing environments. When an employer knows a piece of equipment is defective and leaves it in service, that failure is a violation of § 6400.
How Cal/OSHA Safety Standards Become Evidence in a Lawsuit
Knowing an employer violated a safety rule is one thing. Using that violation in court is another. Labor Code § 6304.5 is the mechanism that bridges the two: it allows Cal/OSHA safety standards, though not the administrative citations themselves, to be introduced in a civil negligence lawsuit as evidence of the applicable standard of care. In practice, this means that if an employer failed to guard a press in violation of a specific Cal/OSHA machine-guarding standard, that violation can be presented to a jury as evidence that the employer breached its duty to you. The statute does not create strict liability. It gives injured workers a concrete, documented benchmark to establish what the employer was required to do and failed to do.
Workers' Compensation Is Usually the Starting Point, but Not Always the End
Under Labor Code §§ 3600 through 3602, workers’ compensation is the exclusive remedy against your employer for most on-the-job injuries. That means, in most situations, you cannot sue your employer in civil court even if they were negligent. However, two important exceptions exist when a defective product is involved. For a full overview of how these rights fit into the broader landscape of California employment protections, see the California Employment Law Guide covering wages, harassment, wrongful termination, and more.
The Product-Liability Exception: Suing Your Own Employer for a Defective Product
Labor Code § 3602(b)(3) carves out a narrow but real exception to the exclusive-remedy rule. Three conditions must all be met:
- Your employer manufactured the defective product.
- The employer sold, leased, or otherwise transferred the product to an independent third party for valuable consideration.
- You encountered the product as a consumer, not in the course of your job duties for that employer.
All three elements are required. The California Court of Appeal drew the line precisely in Behrens v. Fayette Manufacturing Co. (1992) 4 Cal.App.4th 1567, 1574-1575. In that case, the employer manufactured wind turbines and sold them to third parties. An employee was sent by the same employer to repair one of those turbines and was injured by a defect. The court held the exception did not apply because the employee encountered the turbine as part of her primary job duties, not as a consumer. The exclusive-remedy rule barred her civil suit against the employer. Behrens shows exactly where the line is drawn: if your employer sent you to work on or with the product, the exception likely will not protect you.
When the Manufacturer Is Someone Else: Your Right to Sue a Third Party for Product Defects
The more commonly available pathway is a third-party lawsuit under Labor Code § 3852. If the machine, tool, or equipment that injured you was manufactured, distributed, or supplied by someone other than your employer, you can pursue a separate civil claim against that party. This right exists independently of your workers’ comp claim. You do not have to choose one or the other.
For workers in manufacturing settings specifically, this matters enormously. The press, conveyor, forklift, or power tool that injured you was almost certainly made by a company that had no direct employment relationship with you. Under California product liability law, manufacturers, distributors, and sellers can each face liability for a defective product that reaches the marketplace in a dangerous condition. Labor Code § 3852 preserves your right to pursue that claim while your workers’ comp case continues. You can learn more about how these protections apply in manufacturing plant worker rights and legal support.
Understanding the Workers’ Comp Lien on Your Civil Recovery
Winning a third-party lawsuit does not mean you keep the entire recovery. Under Labor Code §§ 3852 through 3856, the workers’ compensation insurer that has already paid your medical bills and wage-replacement benefits holds a subrogation lien on your civil recovery. The insurer can assert that lien against the proceeds of your civil judgment or settlement, up to the amount of benefits it paid. This is not a reason to avoid a third-party claim. A skilled attorney can negotiate the lien, coordinate both claims strategically, and often produce a net recovery for you that workers’ comp alone could never provide. But it is a reason to have representation that understands both systems at once.
What Happens When You Report a Product Defect and Your Employer Retaliates
Some workers are not just injured by defective products. They report the defect, and then they are punished for it. California law treats that sequence as a serious, independently actionable wrong.
What “Retaliation” Includes Under § 6310
Labor Code § 6310 prohibits any employer, or any person acting on behalf of an employer, from retaliating against you for engaging in any of the following protected activities:
- Making an oral or written complaint to Cal/OSHA or any other governmental agency about employee safety or health conditions.
- Instituting or participating in any proceeding relating to your occupational safety or health rights.
- Participating in an occupational health and safety committee established under Labor Code § 6401.7.
- Reporting a work-related fatality, injury, or illness, or requesting access to occupational injury or illness records.
Retaliation includes discharge, demotion, reduction in hours, reassignment to inferior duties, and any other discriminatory action. A worker who was demoted the week after reporting a defective hydraulic press to HR may not realize that action qualifies as a protected complaint. It does. The complaint does not have to be filed with a government agency to trigger protection. An internal complaint to a supervisor about a dangerous machine can be enough.
Who Is Protected, Including Contract Workers and Temporary Employees
Labor Code § 6310 defines “employer” to include client employers as defined in § 2810.3(a)(1) and any employer covered under § 6400(b). This means that if you work for a staffing agency or a contractor placed at a client’s manufacturing facility, the client employer is covered by § 6310’s anti-retaliation prohibition. You do not lose protection simply because your paycheck comes from a third-party staffing firm. Equally important: the statute explicitly extends protection to family members of the employee who engaged in the protected act. If your spouse was demoted or fired because you reported an unsafe condition, that may also constitute retaliation under § 6310. For a deeper look at how these rights connect to broader workplace protections, see the complete guide to manufacturing plant workers’ rights in California.
The Penalties California Employers and Manufacturers Face from Cal/OSHA
Cal/OSHA’s penalty structure gives you a concrete picture of what the regulatory system can impose on employers who allow defective or hazardous equipment to remain in service. As of January 1, 2024, the confirmed penalty schedule from the California Department of Industrial Relations is as follows:
Violation Type | Base / Minimum Penalty (2024) | Maximum Penalty (2024) |
|---|---|---|
Serious | $18,000 (adjustable ±50%) | $25,000 per violation |
General / Regulatory | Not specified as a floor | $15,873 |
Willful or Repeat | $11,337 minimum | $158,727 |
Why California’s Penalties Are Significantly Higher Than the National Average
These figures are not abstract. According to the Report 2024-115 was released/dated July 2025 (July 17, 2025), not 2024; ‘2024-115’ is the report number, not the publication year [source], Cal/OSHA’s average fine for serious violations in fiscal year 2023 was $8,800. The three-year national average reported by federal OSHA was $3,600. California’s average is more than double the national figure. That gap exists because a 2017 California law requires certain Cal/OSHA minimum and maximum penalties to be indexed to the federal Consumer Price Index for All Urban Consumers (CPI-U), with the 2024 inflation adjustment set at approximately 3.24%. The financial exposure for employers who ignore known equipment defects is substantial and grows each year. That exposure also explains why some employers have a financial incentive to suppress internal safety complaints before they reach Cal/OSHA.
Common Mistakes Workers Make After a Product-Defect Injury, and How to Protect Your Claim
The period immediately after a workplace injury is when most claims are won or lost. Below is a checklist of the most common errors and what to do instead.
Post-Injury Mistakes That Can Damage Your Claim
- Failing to photograph the defective equipment before it is repaired or replaced. Once the machine is repaired, modified, or removed, critical physical evidence of the defect is gone. Photograph the equipment, its settings, any missing guards, and the surrounding area as soon as it is safe to do so.
- Not reporting the injury and the defect in writing. An oral report can be denied or minimized. Submit a written injury report that specifically identifies the equipment and describes the defect. Keep a copy.
- Assuming workers’ comp is your only option and not asking whether a third party was involved. Under Labor Code § 3852, if the equipment was made or supplied by any party other than your employer, you likely have a separate civil claim. Many workers never ask this question and lose that right by inaction.
- Waiting too long to seek legal advice. Civil claims have statutes of limitations that run independently of your workers’ comp filing. Delay can permanently bar your civil claim even if your workers’ comp case is still open.
- Discarding communications about the defect. Text messages, emails, work orders, and maintenance logs that reference the defective condition are evidence. Preserve every communication you have access to, including any complaints you or a coworker made before the accident.
- Failing to identify witnesses. Coworkers who saw the defective condition, complained about it, or witnessed the injury are valuable witnesses. Get their names and contact information before they change jobs or memories fade.
- Not documenting retaliation as it happens. If your employer demotes you, cuts your hours, or reassigns you after you reported an unsafe condition, write down the dates, the people involved, and what was said. That contemporaneous record is often the most credible evidence in a § 6310 retaliation claim.
- Signing a broad release without understanding what it covers. Some employers offer quick settlements shortly after an injury. A broad release can waive your right to a third-party civil lawsuit. Never sign any document before consulting an attorney.
What This Means If You Were Injured by Defective Equipment at Work
If you were hurt by a defective machine, tool, or product on the job, your first practical step is to preserve everything: photographs, written reports, communications, and witness information. Those records will determine whether your civil claim survives. Second, do not assume workers’ compensation closes the file. If the equipment was made by any party other than your employer, Labor Code § 3852 gives you a civil claim that can pursue compensation beyond what workers’ comp provides, including damages that workers’ comp does not cover at all. Third, if your employer punished you after you reported the defect, treat that as a separate legal wrong under Labor Code § 6310, with its own remedies. The statutes are specific, the penalty exposure for employers is significant, and the window to act is finite. Contact an attorney before taking any action that might settle or limit your rights.
Frequently Asked Questions
Can I sue the manufacturer and still receive workers’ compensation benefits?
Yes. Labor Code § 3852 expressly preserves your right to pursue both. The workers’ comp insurer will have a subrogation lien on your civil recovery under §§ 3852 through 3856, but that lien can often be negotiated. The two claims are separate and can run concurrently.
What if I am a temp worker or placed by a staffing agency? Do I have the same rights?
Yes. Labor Code § 6310’s anti-retaliation protection covers workers of contractors and temporary staffing firms through the client employer definition in § 2810.3(a)(1). Your third-party civil claim under § 3852 is also unaffected by your employment structure. The identity of who made the defective product matters more than who issues your paycheck.
What counts as “retaliation” under California law?
Under Labor Code § 6310, retaliation includes any discriminatory action: termination, demotion, schedule reduction, reassignment, or any other adverse change taken because you made a safety complaint, participated in a safety proceeding, or reported a workplace injury. Internal complaints to a supervisor about a defective product qualify as protected activity.
Does my employer have to have known about the defect for me to have a claim?
Not necessarily. A third-party product-defect claim under Labor Code § 3852 is based on the manufacturer’s conduct, not your employer’s knowledge. If the product was defectively designed or manufactured, the maker may be liable regardless of whether your employer had prior notice. Your employer’s knowledge of the defect matters more to a negligence claim against the employer and to any Cal/OSHA enforcement action.
What is the Cal/OSHA maximum penalty for a willful safety violation in 2024?
As of January 1, 2024, the maximum Cal/OSHA penalty for a willful or repeat violation is $158,727, with a minimum of $11,337. These figures are adjusted annually based on the federal CPI-U under the 2017 California indexing law.
