Exposure to TCDD (Dioxin)

Ischaemic heart disease - Exposure to TCDD (Dioxin) Factor

The chemical name for TCDD is 2,3,7,8-tetrachlorodibenzo-para-dioxin.  It is commonly referred to as dioxin.

For the purposes of this SOP, the RMA defines inhaling, ingesting or having cutaneous contact with a chemical agent contaminated with TCDD as:

• decanting or spraying,
• cleaning or maintaining equipment used to apply,
• being sprayed with,
• handling or sawing timber treated with,
• being in an environment shrouded in dust from timber treated with, or
• using cutting oils contaminated with

Investigative Documents

Preliminary questions [41504]

41505 there is some evidence that having inhaled, ingested or cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) may be a factor in the development or worsening of the condition under consideration.

41506 the veteran inhaled, ingested or cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) at some time.

41507  the veteran has established the causal connection between exposure to TCDD (Dioxin) and operational service for ischaemic heart disease.

41508   the veteran has established the causal connection between exposure to TCDD (Dioxin) and operational service for the clinical onset of ischaemic heart 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.

41509   the veteran has established the causal connection between exposure to TCDD (Dioxin) and operational service for the clinical worsening of ischaemic heart disease.

Clinical onset and operational service [41508]

41510 the veteran inhaled, ingested or had cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) as specified in the Statement of Principles requirement, before the clinical onset of ischaemic heart disease.

41593 operational service made a material contribution to the veteran having inhaled, ingested or cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) as specified before the clinical onset of ischaemic heart disease.

Clinical worsening and operational service [41509]

41511 the veteran has experienced inhalation, ingestion or had cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD), for a cumulative period of at least 1000 hours within a consecutive period of ten years before the clinical worsening of ischaemic heart disease, and where that exposure has ceased, the clinical worsening of ischaemic heart disease occurred within 25 years after cessation.

41594 operational service made a material contribution to the veteran having inhaled, ingested or cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) as specified before the clinical worsening of ischaemic heart disease.
