Pyrotechnic Safety for the Construction Industry
Pyrotechnic safety on construction sites is a legal requirement in France. The French Labour Code requires employers and project owners to assess risks, including pyrotechnic risk, before any earthworks, drilling, or construction on sites likely to contain unexploded ordnance (UXO). DEMINETEC, certified ISO 9001 and MASE, supports construction companies in managing explosive risk, from historical study to final clearance.
Why secure your construction site?
France has thousands of sites contaminated by war munitions: former WWI and WWII battlefields, military training areas, firing ranges, and bombed sites. Every year, construction sites uncover unidentified explosive ordnance, causing serious or fatal accidents.
The French Labour Code requires employers and project owners to assess risks before starting work in these zones: the pre-works pyrotechnic survey is the tool for this assessment. The project owner is responsible for site safety and can be held liable in case of accidents.
Our methodology
- Historical study — analysis of military archives, identification of risk zones
- Geophysical survey — magnetometric detection of underground anomalies
- Investigation — excavation and identification of detected objects
- UXO clearance — neutralisation, defusing or destruction of ordnance
- Certification — final pyrotechnic clearance certificate

Types of projects concerned
- Road and rail works in bombed zones
- Deep foundations and excavations
- Pipeline and utility installation
- Quarries and mines
- Port developments and underwater works (via SEMTEC)
- Construction on former military sites
- Renewable energy projects (wind farms, solar)

FAQ — Pyrotechnic Safety for Construction
When is pyrotechnic survey mandatory on a construction site?
In France, the French Labour Code (articles L4121-1 to L4121-3 and L4531-1) requires employers and project owners to assess risks, including pyrotechnic risk, before any earthworks, drilling, or construction on a site likely to contain UXO. A pyrotechnic survey is how this assessment is carried out.
What regulations govern pyrotechnic risk in construction?
The framework includes decree 2005-1325 and the French Labour Code (risk assessment), plus STANAG 2143, IMAS, ISO 9001 and MASE.
How does DEMINETEC secure a construction site?
Historical study, geophysical survey, investigation, UXO clearance, and certification.
What types of projects require pyrotechnic safety?
All projects in risk zones: excavations, foundations, pipelines, quarries, port developments, construction on former military sites.
