Petroleum refining and oil-refinery work generates the largest share of benzene exposure lawsuits. Benzene is a chemical in crude oil and gasoline, and chemical and petrochemical manufacturing is the second-largest source of claims.
These lawsuits are personal injury claims by workers who developed blood cancers after benzene exposure at work. The pattern matters for readers checking a possible claim, because the industry alone does not prove a case. Specific jobs, products, and medical history carry more weight.

Which refinery and gasoline jobs face the most claims?
Refinery workers face the most claims because crude oil, gasoline, and refinery streams contain benzene. Hughes Law Offices reports that refinery owners have paid leukemia and myeloma verdicts tied to those exposures, described in an analysis by Hughes Law Offices. Jobs inside refineries, around process units, and around maintenance and turnaround work appear most often. Gasoline-related jobs also file frequently.
CDC/NIOSH lists gas-station attendants, gasoline truck drivers, mechanics, and workers who store or transport benzene and petroleum products, noted on the CDC/NIOSH benzene page. These jobs involve repeated breathing of vapors and skin contact with fuel. One California verdict shows how oil-site exposure can reach beyond a plant. In June 2023, a Santa Barbara County jury awarded $63 million against Chevron and Union Oil after finding they covered up a benzene-laden oil-production sump beneath a home, according to news.law reporting in the report on the Chevron verdict. The later buyer developed multiple myeloma.
Why do chemical, plastic, and rubber workers file claims?
Chemical and petrochemical manufacturing is a second major source of claims. The American Cancer Society states that benzene is used to make plastics, lubricants, rubbers, dyes, detergents, drugs, and pesticides. That broad use creates many points of exposure across production, handling, and cleanup. Rubber-tire, plastics, and rubber manufacturing workers are high-risk claimants.
CDC/NIOSH identifies benzene use in rubber processing and release during tire production. Exposure can come from solvents, process streams, heat, and poor ventilation. Shoe manufacturing and repair is another repeated source. CDC/NIOSH states that benzene was historically used as a solvent and remains as a contaminant in adhesives and solvent mixtures. Repair shops using older glues and solvents face special concern.
What other jobs appear in benzene cases?
Steel and coke-oven work appears repeatedly in benzene cases. CDC/NIOSH includes coke-oven emissions and steel operations among listed exposure settings. Printers exposed to inks and press washes are another group. Laboratory technicians also appear because benzene has been used as a reagent and solvent.
Firefighters face exposure through toxic smoke from burning chemicals and fuels. CDC/NIOSH lists each of these work settings. Railroad and maritime workers round out the repeated group. Their claims often involve fuel, lubricants, solvents, and cargo vapors. Job title alone is not enough, so work location, duties, and materials matter.
What injuries and proof problems shape a claim?
The injuries alleged are mainly blood and bone-marrow cancers. The Law Firm of Melinda J. Helbock states that benzene is classified as an IARC Group 1 human carcinogen linked to acute myeloid leukemia, myelodysplastic syndrome, non-Hodgkin lymphoma, and multiple myeloma, explained in the firm's review of California benzene settlements. That link drives most lawsuit injuries.
Time delay is the main practical limit. The same firm states that benzene cancers often appear 5 to 15 years after first exposure. Workers must prove specific products, jobs, and exposure history, not only industry employment. Readers considering a claim should preserve proof promptly:.
- keep employment records, job titles, dates, and work sites
- write down product names, solvents, fuels, and suppliers while memory is fresh
- save medical records with diagnosis name and diagnosis date
