Manufacturing and Aerospace Workers

Machine operators, assemblers, machinists, welders, fabricators, platers and finishers, maintenance technicians, and quality inspectors.

If a machine did it, there are usually two claims

Workers' compensation is exclusive as to your employer. It is not exclusive as to the company that built the machine.

Where a guard was removed, bypassed, inadequate, or never designed for the foreseeable use of the equipment, there is a products liability case against the manufacturer — and unlike comp, it pays for pain and suffering and disfigurement.

The recurring defendants: press brakes, punch presses, and shears without functioning point-of-operation guarding; conveyors without emergency stops within reach; industrial mixers, balers, and compactors; injection molding machines; CNC equipment; robotic cells with defeated interlocks; and maintenance contractors on lockout/tagout failures.

Preserve the machine. Do not let it be repaired, modified, or scrapped. In a machine injury case this is the difference between a product claim and no product claim, and it has to happen in days.

How third-party claims and liens work.

The 240-week benefit

Labor Code § 4656(c)(3) gives nine listed conditions 240 compensable weeks of temporary disability instead of 104 — 136 extra weeks, up to about $240,000 at 2026 rates.

Four of the nine turn up constantly in this industry:

Amputations · severe burns · high-velocity eye injuries · chemical burns to the eyes

And the 104-week stop is an automated counter, not a judgment about your case. If nothing in the file flags § 4656(c)(3), benefits end on schedule and you are told that is the law. The full framework. · Amputation. · Burns. · Eye injuries.

The exposures

Metals. Hexavalent chromium in stainless welding and plating — a lung carcinogen. Cadmium. Manganese, which produces a parkinsonian syndrome. Lead. Beryllium, which causes chronic beryllium disease and is frequently misdiagnosed as sarcoidosis — a significant issue in aerospace.

Solvents. Trichloroethylene, methylene chloride, toluene, xylene, and n-hexane. Chronic toxic encephalopathy from long-term solvent exposure is real, ratable, and almost always attributed to age, stress, or depression instead. Establishing it requires formal neuropsychological testing. How brain impairment is rated.

Asbestos. Southern California's aerospace and industrial footprint was large, and latency runs 20 to 50 years. Under § 5412 the clock starts at first disability plus knowledge — not at exposure — so claims from 1970s and 1980s exposure are still timely today. Asbestos claims.

Silica, in blasting and finishing. Silicosis claims.

Isocyanates, in coatings — and sensitization can end a career. Chemical exposure claims.

Noise. And note the rating trap: the AMA formula averages 500, 1,000, 2,000 and 3,000 Hz, subtracts a 25 dB fence, and weights your better ear five times more heavily. The classic noise notch at 4,000 Hz is not one of the rated frequencies. Hearing loss.

And heat, in foundries, forges, and enclosed production areas — now covered by 8 CCR § 3396 since July 23, 2024. Heat illness.
