Integrated gas detection, industrial sirens and COMSIR SCADA to comply with the Seveso III Directive (2012/18/EU) and RD 840/2015, with full traceability for internal/external emergency plans and inspections.
The Seveso III Directive (2012/18/EU) and RD 840/2015 require all affected establishments (lower and upper tier) to have an Internal Emergency Plan (PEI); the External Emergency Plan (PEE) is only required for upper-tier establishments and is drawn up by the regional civil protection authority, with the operator's cooperation, to ensure effective public warning in the event of a major accident. At Lafcarr we design and deploy systems that cover the whole cycle: incident detection, notification to the operator and Civil Protection, alarm activation and audible public warning, with an audited record of every action.
A major accident at a SEVESO site —leak, fire or explosion— can escalate within minutes. The operational key is to minimise the time from the start of the incident (t1) to the public receiving the warning (t3), via detection/notification (t2) and alarm activation.
We work on every element of the cycle to cut these times to a minimum: sensors with automatic thresholds, redundant active-active communications and direct siren activation without relying on manual intervention. The warning zone is determined by ISO 9613 acoustic simulation, guaranteeing real, verifiable coverage.

High power for effective coverage around industrial perimeters. Coverage area calculated by ISO 9613 acoustic simulation.
Detection of chlorine, NH₃, H₂S and other toxic gases. Thermal IP cameras for a real-time view of the site.
Local, central or cloud-hosted control solutions, with protected communications and a redundant architecture for maximum availability.
Scenario management, alarm activation, 24/7 traceability and auditable reports. Integration with 112, CECOP and the external plan via standard API.
From the technical drafting of the internal plan to commissioning the system and support during official drills. In-house siren manufacturing, our own software and communications designed not to fail when it matters most.
Detection, control and warning systems deployed in the chemical and petrochemical industries and industrial ports in Spain.
Directional siren network integrated with Civil Protection via TETRA communications, with coordinated activation from the regional CECOP.
Chemical detection and audible warning system integrated with the External Emergency Plan, with coordinated activation from the site's control centre.
Electronic siren network, chemical sensors and COMSIR control at an upper-tier port facility, with redundant IP and radio communications.
We answer the questions most often raised by site operators, Civil Protection officials and engineering firms during design, tendering or plan updates.
The Seveso III Directive (2012/18/EU), transposed in Spain by RD 840/2015, requires all affected establishments to draw up Major Accident Prevention Policies (PPAG) and an Internal Emergency Plan (PEI). Upper-tier establishments must also cooperate with the regional civil protection authority in drawing up the External Emergency Plan (PEE), which that authority approves and activates. The operator must have the technical means to report the incident to Civil Protection and to warn workers and the affected population within the times set out in the applicable plan.
Where the site's risk analysis and internal/external plans call for it, the electronic siren is usually the recommended solution because it doesn't depend on people having an active, up-to-date device: the message reaches everyone at the same time, is consistent, has no distribution errors and works independently of external operators. Other channels (SMS, mobile apps and FM radio) are useful as a complement; the final choice of medium is set out in the plan approved for each site.
The warning zone is determined from the site's risk analysis: type and quantity of substance, accident scenarios and the external plan's intervention and maximum alert zones. Based on that zone, we run an ISO 9613 acoustic simulation to size the number, type and position of sirens needed for effective coverage. The result is an isophone study that can be submitted to the competent authority as technical evidence.
Yes. COMSIR integrates with existing industrial SCADA systems via standard protocols (MODBUS, OPC, IEC 60870-5-104, DNP3 and API/REST). It can also connect with Civil Protection systems (112, CECOP) and the operator's internal emergency plan procedures, so that alarm activation is built into the internal emergency management workflow.
The system includes periodic test and drill protocols with automatic logging in COMSIR: checklist, activation records, the status of every node and communications evidence. All of this is available to present to the competent authority during inspections or external plan reviews, with no extra preparation.
We work with site operators, engineering firms and Civil Protection bodies to design and deploy systems that comply with RD 840/2015: from the acoustic study and technical architecture to commissioning, drills and operational maintenance.
