[Asbestos in the National Navy: Employment-exposure matrix]

Area of Science:

• Occupational Health
• Environmental Medicine
• Naval Medicine

Background:

• Asbestos exposure poses a significant health risk, particularly within military occupations.
• French Navy personnel show a disproportionately high incidence of asbestos-related diseases, with 94% of compensated victims originating from this branch.
• Existing employment-exposure matrices are insufficient for military populations, highlighting a critical gap in occupational health assessment.

Purpose of the Study:

• To develop the inaugural employment-exposure matrix specifically for the French Navy.
• To enhance the accuracy and effectiveness of post-occupational medical surveillance for naval personnel.
• To quantify asbestos exposure risks within various naval roles and environments.

Main Methods:

• A comprehensive bibliographic search was conducted, focusing on asbestos in naval repair, shipboard environments, and foreign naval practices.
• Key databases (e.g., Medline, Pubmed) were queried using terms such as "Navy," "Asbestos," "Shipyard," and "Military."
• Existing theses and relevant literature were systematically reviewed to gather pertinent data.

Main Results:

• Epidemiological and bibliographic data confirm a heightened risk of asbestos-related diseases within the French Navy.
• Key factors influencing risk include specific job roles (especially those with direct asbestos contact, like machine personnel), ship commissioning year, and duration of naval service.
• For personnel without direct asbestos contact, risk is primarily determined by the ship's age, onboard asbestos presence, and seafarer exposure duration.

Conclusions:

• The developed matrix allows for risk classification aligned with French Health Authority recommendations.
• This facilitates the implementation of tailored and adequate post-professional medical follow-up programs for French Navy personnel.
• The findings underscore the need for targeted occupational health strategies in naval environments.
