Preliminary questions [34579]

24551

there is some evidence that inhaling respirable crystalline silica dust may be a factor in the development or worsening of the condition under consideration.

34641 the veteran has inhaled respirable crystalline silica dust as defined in the Statements of Principles for rheumatoid arthritis at some time.

40346the veteran has established the causal connection between inhaling respirable crystalline silica dust and VEA service for rheumatoid arthritis.

34642the veteran has established the causal connection between inhaling respirable crystalline silica dust and VEA service for the clinical onset of rheumatoid arthritis.

34643the veteran has established the causal connection between inhaling respirable crystalline silica dust and operational service for the clinical onset of rheumatoid arthritis.
