Claim of Lemery v. Flintkote Co.
Claimant, who developed acute pharyngitis and bronchitis in 1967, experienced a significant worsening of his respiratory condition in 1973 when his employer changed to a “dry” cement manufacturing process, exposing him to extreme dust. This exposure led to pneumonia, chronic bronchitis, and eventual incapacitation, forcing him to stop working multiple times. After being advised not to return to work under dusty conditions, he was re-employed as a janitor in a dust-free area, and his symptoms diminished. The Workers' Compensation Board found that his employment exposure aggravated a preexisting nondisabling bronchitis into a disabling condition, allowing his claim for benefits. The employer and carrier appealed, arguing that occupational aggravation of a nonoccupational disease is not compensable. The court affirmed the Board's decision, stating that the ultimate test is whether employment causes a disability that previously did not exist.
