The exposure that ends careers

Isocyanates, in two-part polyurethane paints, clearcoats, primers, and hardeners.

They cause occupational asthma with sensitization — and sensitization is the key word. Once you are sensitized, exposure at any level, however small, can provoke a severe reaction.

Which means the practical consequence is not a percentage of impairment. It is that you can never work in a body shop again.

That gap — between a modest impairment rating and a total loss of occupational capacity — is where these cases are won or lost, and it is why vocational evidence matters more here than the AMA Guides do. How permanent total disability is proved.

Get the Safety Data Sheets. Your employer must maintain them and make them accessible, and must retain exposure records for 30 years. Request them in writing. How to build a chemical exposure claim.

The rest of the chemistry

Solvents — toluene, xylene, methylene chloride, and mineral spirits in cleaners, thinners, and degreasers. Chronic toxic encephalopathy from long-term solvent exposure is real, ratable, and almost always misattributed to age, stress, or depression. Establishing it requires formal neuropsychological testing. How brain impairment is rated.

Welding fume, including hexavalent chromium in stainless work, and manganese, which produces a parkinsonian syndrome.

Asbestos in brake and clutch work. Latency of 20 to 50 years, and the deadline rules are unlike anything else in the code — under § 5412 the clock starts at first disability plus knowledge, not at exposure. A mechanic who worked brakes in the 1980s and is diagnosed today may well have a timely claim. Asbestos claims.

Diesel exhaust, battery acid, carbon monoxide, and silica in blasting and body filler sanding.

The mechanical injuries

Shoulders — a lifetime of overhead work under a lift. This is the signature cumulative trauma injury of the trade, and it comes with a rating fact worth knowing in advance: the AMA Guides contain no impairment value for a rotator cuff tear, and a repair that restores motion can rate at zero. What carries value is lost motion — and a distal clavicle resection, which has a fixed value and is routinely buried in the operative report. The full explanation.

Backs, from lifting transmissions, wheels, and equipment.

Hands and wrists, from impact wrenches, ratchets, and sustained grip. Vibration is an independent risk factor, and hand-arm vibration syndrome is under-diagnosed. Carpal tunnel and repetitive strain.

Knees, from kneeling, squatting, and concrete. Knee injuries.

Burns, from exhaust, coolant, and welding. Burn injuries.

Eye injuries — grinding, cutting, and chipping. High-velocity eye injuries are on the § 4656(c)(3) list, which means 240 weeks of temporary disability instead of 104. Eye injuries.

Crush and amputation — lifts, jacks, presses, and tire machines. A machine injury is frequently a product case against the manufacturer, which pays for pain and suffering when comp does not. Amputation. · Third-party claims.

And noise. Hearing loss.
