Safety and Compliance

Our Pyrotechnic Depollution Operators (PDOs), Pyrotechnic Site Managers (PSMs) and Mine Clearance Technicians are qualified and highly experienced. They ensure that pyrotechnic clearance complies with the strictest standards, guaranteeing site safety and environmental protection. Each intervention is carried out with absolute rigor to minimize risks and ensure regulatory compliance.

Comprehensive Project Management

We take charge of every stage of your pyrotechnic cleanup project, from historical and technical study to waste disposal . This integrated approach allows you to benefit from a turnkey solution, simplifying the management of these complex projects and providing you with total peace of mind.

Complex interventions

We very often intervene during complex clean-up operations on sites with several types of contaminants (chemicals, asbestos, heavy metals, hydrocarbons...). Our "Pyro" experts can then rely on all the complementary skills of the Séché Environnement group, specialists in hazardous waste and large-scale remediation operations.

Reactivity and flexibility

We are renowned for our ability to intervene quickly and adapt to all situations, whether for emergency interventions or planned projects. Our team is ready to respond as quickly as possible to help you ensure business continuity.

Administrative procedures management

We have a perfect knowledge of the necessary administrative and regulatory procedures, and can also help you coordinate relations with prefectural or municipal services or civil security.

Cutting-edge technologies

To guarantee the efficiency of our interventions, we use state-of-the-art equipment such as a multi-probe cart or a remotely-operated hydraulic excavator. These advanced technologies enable us to detect and neutralize unexploded ammunition with greater accuracy and speed, reducing disruption and costs on your worksite.

How do we do it?

The stages of your project

1. Historical and Technical Study of Pyrotechnic Pollution (HTPP)

This first step involves consulting local, national and international archives to assess risks and identify areas potentially contaminated by unexploded ordnance. SNCF archives, bombing mission reports and other historical sources are analyzed to obtain an overview of the contamination.

2. Pyrotechnic assessment

Diagnostics involves the use of advanced technologies to detect anomalies in the soil. Commonly used methods include:

  • Magnetometry: measuring variations in the earth`s magnetic field to detect metallic objects.
  • Electromagnetism: using electromagnetic detectors to identify potential targets.
  • Georadar (GPR): sending electromagnetic waves into the ground to detect changes in dielectric constant.
  • Multi-probe carts: mapping electromagnetic disturbances over large areas.

3. Risk assessment

If anomalies are detected, a risk assessment is carried out to determine the nature of the objects found and their hazardousness. This step is crucial for planning clean-up operations in complete safety.

5. Pyrotechnic clean-up

This stage involves excavating the identified targets and confirming their nature. Techniques used include:

  • Mechanical excavation: using hydraulic excavators to dig and extract objects. We have a remotely operated excavator to avoid endangering our operators.
  • Manual intervention: manual approach for sensitive or hard-to-reach objects.
  • Neutralization and destruction: we facilitate civil security intervention to neutralize and destroy unexploded ordnance.

6. Waste management

Pyrotechnic residues and other hazardous waste are treated and disposed of in accordance with current regulations. This may include sorting, disposing of or burning the waste to minimize its environmental impact.

7. Pyrotechnic clearance certificate

After any intervention we provide you with a Pyrotechnic Clearance Certificate which guarantees that your site is now safe for future users. This is an essential document to meet the requirements of public authorities and insurers.
