Firefighters

You have the strongest position in California workers' compensation — and the one most often left unused.

Full salary instead of two-thirds under § 4850. Presumptions that make cancer, heart trouble, pneumonia, and post-traumatic stress industrial unless the department proves otherwise. And several of those presumptions follow you into retirement.

Full salary, not two-thirds

Labor Code § 4850 gives eligible firefighters a leave of absence at full salary in lieu of temporary disability, for up to one year.

Full salary, not two-thirds, and not capped at the 2026 maximum of $1,764.11 a week.

(On tax: ordinary workers' compensation benefits are excluded from gross income under IRC § 104(a)(1), and § 4850 salary continuation is generally treated the same way because it is paid in lieu of temporary disability under the workers' compensation law. But § 4850 itself says nothing about taxation, agencies differ in how they report it, and this is a tax question rather than a Labor Code one — confirm it with a tax professional.)

It covers city and county firefighters, certain district and state classifications, and fire department members in a range of roles. The statutory list is specific. If someone has told you § 4850 does not apply to your classification, that is worth checking against the text rather than accepting.

The presumptions — what they actually do

A presumption reverses the burden of proof. Ordinarily you must show the job caused the condition. Under a presumption, the condition is industrial unless the department proves it is not — and for most of these, the statute provides that the presumption may not be attributed to any disease existing before employment.

Cancer — Labor Code § 3212.1. This is the one that matters most and is claimed least. The presumption applies to a firefighter who demonstrates exposure to a known carcinogen, and it extends past separation from service on a sliding scale tied to years of service — up to 120 months.

Read that again. A cancer diagnosis years after you retired can still be a claim. People do not file because they no longer think of themselves as firefighters. The statute still does.

Heart trouble — § 3212. Includes hypertension. Extends past retirement on the same sliding scale.

Pneumonia and tuberculosis — § 3212.

Bloodborne infectious disease, methicillin-resistant staphylococcus aureus, and meningitis — § 3212.8 and related sections.

Biochemical exposure — § 3212.9.

Post-traumatic stress — § 3212.15. This one has effective dates and sunset provisions that have been extended more than once. Check the current text rather than an article, because published material in this area goes stale fast and the difference is whether you have a presumption or a § 3208.3 case.

The presumptions in detail, condition by condition.

What we see

Cancer. Firefighters are exposed to a documented mix of carcinogens — combustion products, diesel exhaust in the apparatus bay, PFAS in turnouts and in foam, asbestos in older structures. The presumption exists because the science supports it.

Cardiac. Sudden extreme exertion from a resting state, heat, and sustained physiological stress.

Musculoskeletal. Shoulders, knees, and low back from carrying weight over uneven ground. Much of it presents as cumulative trauma, which has its own date-of-injury rule under § 5412 and is fully compensable. How cumulative trauma works.

Hearing loss. Sirens, apparatus, saws, and decades of it. Hearing loss claims.

Post-traumatic stress. Pediatric calls, line-of-duty deaths, mass casualty incidents, and the cumulative weight of a career of them.

Heat illness. When heat becomes a claim.

Retirement is where this gets decided

Industrial disability retirement through CalPERS, a county system, or a city system runs alongside the comp case, and Government Code §§ 21150 and 21153 govern the interaction. A determination in one proceeding can bind the other.

Do not settle a workers' compensation case without knowing what it does to a pending IDR application, and do not let an IDR determination be made without knowing what it does to the comp case. This is the single most consequential coordination problem in public safety claims and it is routinely handled backwards.

Vigil v. County of Kern (2024, en banc) matters where multiple body parts combine. Wilson v. Cal Fire (2019, en banc) matters on apportionment of psychiatric injury.
