Provide for compensation under the Nebraska Workers' Compensation Act for cancers experienced by firefighters

Nebraska's LB 400 expands the state's Workers' Compensation Act to cover specific cancers diagnosed in firefighters as occupational diseases. It directly affects professional and volunteer firefighters with five or more years of service, creating a rebuttable presumption that certain cancers (like lung, leukemia, or bladder cancer) are work-related if linked to exposure to listed carcinogens - such as diesel exhaust, formaldehyde, or asbestos - during firefighting duties. The bill specifies 25 cancer types and their associated carcinogens, and establishes a presumption for active firefighters diagnosed during employment, plus a 60-month window post-retirement for retired firefighters. This eliminates the need for complex proof of causation in covered cases, streamlining compensation claims for affected firefighters.
