Pyrotechnic Safety for Construction

Pyrotechnic Safety for the Construction Industry

Pyrotechnic safety on construction sites is a legal requirement in France. Decree 2011-45 mandates a pyrotechnic survey 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.

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.

Decree 2011-45 makes it mandatory to conduct a pyrotechnic survey before starting work in these risk zones. The project owner is responsible for site safety and can be held liable in case of accidents.

1. Historical study — analysis of military archives, identification of risk zones
2. Geophysical survey — magnetometric detection of underground anomalies
3. Investigation — excavation and identification of detected objects
4. UXO clearance — neutralisation, defusing or destruction of ordnance
5. Certification — final pyrotechnic clearance certificate

• 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)

DEMINETEC operates within a strict regulatory framework:

• Decree 2005-1325 — pyrotechnic activities regulation
• Decree 2011-45 — mandatory pre-work survey
• ISO 9001 — quality management
• MASE — safety management
• STANAG 2143 — NATO standards (IMEC, CMD 1&2)

When is pyrotechnic survey mandatory on a construction site?

In France, decree 2011-45 requires a pyrotechnic survey before any earthworks, drilling, or construction on a site likely to contain UXO.

What regulations govern pyrotechnic risk in construction?

The framework includes decree 2005-1325 and decree 2011-45, 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.
