Understanding hazards in Bertrange
The assessment of industrial and natural hazards in Bertrange crosses several official public bases: ICPE (Géorisques DGPR), Seveso sites, flood plans (PPRI), seismicity (BRGM) and radon potential (IRSN). The weighted overall score comes out moderate.
In practice, the town has 3.7 % of surface in ICPE, of which an unrecorded share at the commune level in Seveso sites with major industrial risk. A flood plan (PPRI) covers 1.0 % of the territory (buyer-tenant disclosure mandatory at sale). The radon potential is 1/3 low according to the IRSN classification.
For a purchase, the State of Risks and Pollutions (ERP) is mandatory and must be appended to the sale agreement. It lists all natural disaster orders (CatNat), PPR zones, and known polluted sites. To request systematically, ideally before the offer.

Frequently asked questions
How to know if my address is concerned by a flood plan (PPRI)?
The State of Risks and Pollutions (ERP) is mandatory at sale and rental. The seller or landlord must give it to you appended to the agreement. You can also check directly georisques.gouv.fr with your address.
Seveso site within 500 m: danger?
An upper-tier Seveso site has a PPRT binding on building permits. The lethal effect zone is typically < 500 m, the serious-injury zone < 2 km. At 500-2000 m, risks are monitored (SAIP alert) but existing buildings remain insurable.
High radon: what to do?
Radon is a radioactive gas of geological origin, present in granitic subsoil (Brittany, Massif Central, Vosges). For levels > 300 Bq/m³, IRSN recommendations: enhanced ventilation, slab sealing, continuous measurements. Intervention cost: 500-5000 €.
How does home insurance account for hazards?
Natural disasters are covered mandatorily (12 % contribution of the multi-risk contract). Clay shrink-swell (RGA) is rising rapidly (climate change) and some areas see insurance refusals or high deductibles. Compare several insurers before signing.
Sources: Géorisques (DGPR) — ICPE, Seveso, PPRI, BASIAS/BASOL. BRGM — seismicity, clay shrink-swell. IRSN — radon potential. ERP mandatory at sale (Environment Code L.125-5). The overall score is an NTYP composite (weighting of the dimensions above) — see our methodology.
