Why monitor tanks on an ICPE or SEVESO site ?

Understanding the challenges: safety, compliance, environment

On an ICPE or SEVESO classified site, the management of industrial tanks leaves no room for improvisation. A storage facility for chemical substances or petroleum products presents a particular risk. risk risk ofemissionof pollutionor evenexplosion. Visit treatment of these risks requires a reliable reliable measurement systemcapable of transmitting information real-time information on levels liquid levels flowsor temperature or pressure thresholds.

👉 A LITTLE HISTORY:
The name “SEVESO” comes from an industrial accident in 1976, near the Italian town of Seveso. A massive leak of dioxin due to the lack of an emergency plan contaminated theenvironmentcontaminated the environmenthospitalization of childrenhospitalization death of animals and serious ecological consequences and health consequences. This event served as the basis for the SEVESO directive subsequently adopted by the European Union, which is still in force today.

Plant safety

Continuous monitoring to anticipate incidents, limit hazardous emissions and avoid breaking points.

Regulatory compliance

Compliance with ICPESEVESO III directive, hazard statements (H224, H225), NF standards and storage threshold requirements.

Preserving the environment

Effluent control, spill limitation, control of gas and chemical emissions into water or air.

What is an ICPE or SEVESO site?

An ICPE (Installation Classée pour la Protection de l’Environnement) refers to any industrial industrial activity likely to emit hazardous substances or generate an impact on the impact on the environment. These installations are subject to strict regulations because of the risks related to their operation: fire, explosion, chemical chemical productswater or air pollution.

Visit SEVESO sitesThese are ICPEs subject to stricter obligations, due to the volume or nature of the substances stored (classified as H224, H225, etc.). They must implement technical provisionstechnical emergency plans and rigorous monitoring of tank levels.

Risks associated with poor reservoir management

No reliable measuring systemindustrial tanks and vessels present a number of hazards:

🔥 Fire or explosion In the event of overfilling or accumulation of flammable gases, particularly on products classified as H224 / H225.

🌍 Soil and water pollution undetected leakage or spillage of effluents or toxic substances

💨 Hazardous substance leak: uncontrolled emissions impacting operators and the immediate environment

Key figures

According to Ineris, nearly 60% of incidents reported at SEVESO sites since 2020 are linked to failure to monitor or maintain of storage equipment.

Regulatory requirements (ICPE / SEVESO decrees)

Operators of ICPE and SEVESO sites must comply with a series oftechnicaladministrative and environmental requirements:

  1. Installation of an automated measurement system and real-time level monitoring
  2. Data recording (stocks, thresholds, volumes) for control by authorities
  3. Detection of anomalies (leakage, overpressure, critical level) with immediate transmission
  4. Prevention plans for hazardous products, particularly highly flammable liquids
  5. Monitoring of indicators relating to 6 RV Risks: fire, explosion, pollution, substances, environment, human

Real-time monitoring and data visualization

Our telemetry system enables continuous continuous measurement of your tanks, cisterns and reservoirs, regardless of the type of type of substance stored (flammable liquid, effluent, chemical product). The data is automatically transmitted to our cloud platform, which can be consulted via web interface and mobile application or on a local display.

In just a few clicks, operators can visualize the status of each installationwith values updated every X minutes (depending on the package chosen, between 2 and 5 minutes). A precise digital twin map of the site allows you to visually locate the equipment under surveillance, as well as any ancillary equipment (fire extinguishers, trucks, etc.).

Additional options (premium offer ) :

  1. Physical alerts (flashing beacon, audible, etc.) and customizable digital alerts
  2. A reading every 2 minutes in the event of movement
  3. Parameterization of your equipment online or on the PLC
  4. IP66 touchscreen
  5. Actuators for pumps or access control via RFIP badge

FAQs

An ICPE (Installation Classée pour la Protection de l’Environnement) site is an industrial industrial facility likely to generate nuisances or risks (pollution, fire, explosion). It is governed by specific regulations according to the hazardous nature of products handled or stored.

The SEVESO directive imposes prevention and control measures for sites handling large quantities of hazardous substances. For tanks, this includes a precise monitoring of levelslevels, safety thresholds, emergency plans (POI), and strict documentary traceability.

A connected gauge measures liquid or gas level inside a tank, using a sensor (radar, pressure, ultrasound). The data is sent automatically to a cloud platformaccessible in real time from any computer or mobile device.

The main risks include : fires, explosions, toxic emissions, leaks of hazardous products, water pollution or soil. Insufficient monitoring or a missed warning can have serious consequences for people and the environment.

Compliance requires rigorous management with real-time monitoring of tank levels, automatic report generation, prevention plans, preventive maintenance and compliance with regulatory thresholds defined in ministerial ministerial decrees ministerial decrees.

The technologies used include radar radar, hydrostatic pressure, ultrasonic or connected to a PLC. The choice depends on monitored productATEX constraints, the available network (NB-IoT, LTE-M, LoRa…) and the level of accuracy required.

For avoid overflow, anticipate incidents, limit emissions and guarantee regulatory compliance. A connected gauge gives you greater safety, efficiency and visibility over the status of your installations, without the need for manual intervention.
