CARSAT Bretagne: what grants exist to prevent occupational risks?

The role of CARSAT Bretagne

CARSAT Bretagne acts on behalf of Assurance Maladie — Risques professionnels and processes applications for prevention financial aid from establishments within its territory. The schemes can fund certain equipment, diagnostics, training or layout changes related to occupational health and safety. The aid varies according to headcount, sector, the risk targeted and the applicable specifications.

The two grants referenced in Capital OS

The reference database links two grants to CARSAT Bretagne: « Locaux + sûrs » (safer premises) and « Réduction de l’exposition au gaz radon » (reducing radon gas exposure). The first concerns the design or renovation of workplace premises; the second covers screening, expert assessment and reducing radon exposure. They are intended for specific prevention projects, not for general investments unrelated to an occupational risk.

Locaux + sûrs: building or renovating with prevention built in

This grant aims to improve working conditions by adapting premises to the planned activity. The listed eligible expenses include collective fall-from-height protection, secure roof access, protection of fragile overhead lighting elements, separating traffic flows on outdoor circulation routes, as well as certain natural lighting and acoustic absorption fittings.

Conditions for Locaux + sûrs

The listed conditions include being up to date on occupational accident and disease (AT/MP) contributions, membership of an occupational health and prevention service (SPST), an up-to-date DUER (single risk assessment document) in line with applicable rules, no ongoing formal notice or additional contribution, and informing staff representatives of the project and the application.

Reducing exposure to radon gas

This aid aims to reduce employees’ exposure to radon in workplace premises. The reference database cites initial screening, assessment of entry pathways when measurements exceed 300 Bq/m³, work to reduce exposure, and an electronic measuring device. Second-hand equipment, leasing, hire-purchase and expenses borne by an SCI (real-estate holding company) are listed as excluded.

Who can benefit from the grants?

The listings target micro-businesses and small companies, with precise conditions linked to headcount, contribution scheme, occupational risk and project type. For radon, the project must aim to reduce exposure in workplace premises. Location in Brittany or company size alone is not enough to demonstrate eligibility.

How do you apply for the aid?

First identify the risk, then check the award conditions and the list of eligible expenses. Prepare quotes, prevention supporting documents, administrative paperwork and, for radon, the required measurements or diagnostics. CARSAT Bretagne states that Subvention Prévention applications are filed from the company account on Net-entreprises, via the AT/MP account. Check whether the application must be registered before placing the order or starting the work.
