Claimant Report - Inhaling Respirable Crystalline Silica Dust [CR9314]
Preliminary questions [40654]
there is some evidence that inhaling respirable crystalline silica dust in an enclosed space may be a factor in the development or worsening of the condition under consideration.40730 the veteran has inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease at some time.
40731 — the veteran has established the causal connection between inhaling respirable crystalline silica dust in an enclosed space and VEA service for fibrosing interstitial lung disease.
40732 — the veteran has established the causal connection between inhaling respirable crystalline silica dust in an enclosed space and VEA service for the clinical onset of fibrosing interstitial lung disease.
40734 — the veteran has established the causal connection between inhaling respirable crystalline silica dust in an enclosed space and operational service for the clinical onset of fibrosing interstitial lung disease.
or
40735 — the veteran has established the causal connection between inhaling respirable crystalline silica dust in an enclosed space and eligible service for the clinical onset of fibrosing interstitial lung disease.
or
the clinical onset of the condition under consideration occurred after the end of the veteran's last period of VEA service. the condition under consideration permanently worsened.40733 — the veteran has established the causal connection between inhaling respirable crystalline silica dust in an enclosed space and VEA service for the clinical worsening of fibrosing interstitial lung disease.
40736 — the veteran has established the causal connection between inhaling respirable crystalline silica dust in an enclosed space and operational service for the clinical worsening of fibrosing interstitial lung disease.
or
40737 — the veteran has established the causal connection between inhaling respirable crystalline silica dust in an enclosed space and eligible service for the clinical worsening of fibrosing interstitial lung disease.
Clinical onset and operational service [40734]
the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours. the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours before the clinical onset of fibrosing interstitial lung disease. where the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours before the clinical onset of fibrosing interstitial lung disease, the first such inhalation commenced at least five years before the onset. operational service made a material contribution to the veteran's inhalation of respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours before the clinical onset of fibrosing interstitial lung disease.Clinical onset and eligible service [40735]
the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 3000 hours. the veteran inhaled respirable crystalline silica dust in an enclosed space 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. where the veteran inhaled respirable crystalline silica dust in an enclosed space 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 ten years before the onset. eligible service made a material contribution to the veteran's inhalation of respirable crystalline silica dust in an enclosed space 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.Clinical worsening and operational service [40736]
the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours. the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours after the clinical onset and before the clinical worsening of fibrosing interstitial lung disease. where the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours before the clinical worsening of fibrosing interstitial lung disease, the first such inhalation commenced at least five years before the worsening. operational service made a material contribution to the veteran's inhalation of respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 1500 hours before the clinical worsening of fibrosing interstitial lung disease.Clinical worsening and eligible service [40737]
the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 3000 hours. the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 3000 hours after the clinical onset and before the clinical worsening of fibrosing interstitial lung disease. where the veteran inhaled respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 3000 hours before the clinical worsening of fibrosing interstitial lung disease, the first such inhalation commenced at least ten years before the worsening. eligible service made a material contribution to the veteran's inhalation of respirable crystalline silica dust in an enclosed space as defined in the Statements of Principles for fibrosing interstitial lung disease for a cumulative period of at least 3000 hours before the clinical worsening of fibrosing interstitial lung disease.
