Preliminary questions [40655]

40677

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

40752 the veteran has inhaled respirable crystalline silica dust in an open environment as defined in the Statements of Principles for fibrosing interstitial lung disease at some time.

40753the veteran has established the causal connection between inhaling respirable crystalline silica dust in an open environment and VEA service for fibrosing interstitial lung disease.

40754the veteran has established the causal connection between inhaling respirable crystalline silica dust in an open environment and VEA service for the clinical onset of fibrosing interstitial lung disease.

40756the veteran has established the causal connection between inhaling respirable crystalline silica dust in an open environment and operational service for the clinical onset of fibrosing interstitial lung disease.

or

40757the veteran has established the causal connection between inhaling respirable crystalline silica dust in an open environment and eligible service for the clinical onset of fibrosing interstitial lung disease.

or

7334

the clinical onset of the condition under consideration occurred after the end of the veteran's last period of VEA service.

7335

the condition under consideration permanently worsened.

or

40759the veteran has established the causal connection between inhaling respirable crystalline silica dust in an open environment and eligible service for the clinical worsening of fibrosing interstitial lung disease.

Clinical onset and operational service [40756]

40760

40762

the veteran inhaled respirable crystalline silica dust in an open environment as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 3000 hours before the clinical onset of fibrosing interstitial lung disease.

40766

where the veteran inhaled respirable crystalline silica dust in an open environment as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 3000 hours before the clinical onset of fibrosing interstitial lung disease, the first such inhalation commenced at least five years before the onset.

40770
