The Dangers of Working With Power Tools—and Your Rights If You’re Hurt
Power tools cause thousands of serious injuries every year—lacerations, amputations, eye injuries, electric shock, and hearing loss are common. When a defective tool, a missing safety guard, or another party’s negligence causes the injury, California workers can recover through workers’ compensation and, where a third party or a product defect is involved, a separate personal-injury or product-liability claim for full damages.

What are the most common power-tool injuries?
The most frequent serious injuries include deep lacerations and amputations from saws and grinders, eye injuries from flying debris, electric shock and burns from faulty or improperly grounded tools, crush injuries, and hearing loss from prolonged exposure. Nail-gun and table-saw injuries are among the most severe and are frequently tied to missing or defeated safety guards.
When is a power-tool injury someone else’s fault?
A power-tool injury may support a claim beyond workers’ comp when a defective tool (a design or manufacturing defect, or inadequate warnings) caused the harm—a product-liability claim against the manufacturer—or when another party removed a guard, failed to maintain equipment, or created an unsafe condition. Under California law, a manufacturer can be strictly liable for a defective product that injures a user.
What compensation is available?
Workers’ compensation covers medical treatment and a portion of lost wages regardless of fault. A third-party or product-liability claim can add the rest—full lost earnings, future medical care, and pain and suffering—which workers’ comp does not pay.
How do you prove a defective-tool claim?
Preserve the tool itself—do not discard or repair it—along with the packaging, manual, and any warnings. Photograph the injury and scene, keep the receipt or purchase record, and get names of witnesses. A product-liability case often turns on expert examination of the tool and its safety features, so the physical evidence is essential.

Frequently Asked Questions
Can I sue the manufacturer of a defective power tool?
Yes. If a design defect, manufacturing defect, or inadequate warning caused your injury, you can bring a product-liability claim. California applies strict liability, meaning you generally need to prove the defect and that it caused your injury, not that the manufacturer was careless.
What should I do with the tool after an injury?
Keep it. Do not throw it away, repair it, or return it. The tool, its guards, packaging, and manual are the key evidence in a defective-product claim and must be preserved for expert inspection.
Does workers’ comp cover power-tool injuries?
Yes, if you were injured on the job, workers’ compensation covers medical care and part of your lost wages regardless of fault. A separate third-party or product claim can recover pain and suffering and full lost earnings.
How long do I have to file a claim?
In California you generally have two years to file a personal-injury or product-liability lawsuit (CCP §335.1) and one year for a workers’ compensation claim.
