Our technical office at your service!

We offer design for Gas Fire ATEX SIL, D.P.R. 37/08 e D.M. 04.05.1998

Outlines the main design engineering services fire gas extinguishing system that may be provided by our Company SV sistemi di sicurezza with respect to new installations of fire detection & alarm and fire-fighting systems.

1) Fire risk analysis within the overall risk analysis of the plant
2) SIL (Safety Integrity Level) classification of the fire safety functions in the SIL evaluation of the process, i.e when the fire safety functions are considered as safety instrumented functions;
3) Review of Code (NFPA) and local requirements and compliance with the requirements of the authorities having jurisdiction (AHJ);
4) Preliminary design of fire alarm and fire-fighting systems for acceptance by the local authorities

Request for issuing the Certificate of Fire Prevention

In the context of D.P.R. 37/08 e D.M. 04.05.1998
    • Listing of fire work adjustment (through inspection / in the concerned areas or opinions of existing compliance);
    • Fire-fighting assistance to supervision (for the proper implementation of the work planned, with determination of no significant variations for fire safety and verification of the individual works included in the list);
    • Responsibility for requesting CPI (collecting certifications and declarations required, submission of the request of the ICC to the Provincial Command of the Fire Brigade, general final exam activity, presentation of DIA to the Provincial Command of the Fire Brigade and protocollato returning the document to the client);
    • Evaluation of fire risks (according to Annex 1 of the Ministerial Decree 10 March 1998, through the determination of fire hazards, identification of exposed persons, the elimination or reduction of fire hazards, the classification of the level of residue fire risk and the adequacy of safety measures);
    • Escape routes (general and particular predisposition of graphic tables, compiled in the Mechanical Protection Fire project, the fire evaluation risk and the Emergency plan);
    • the emergency plan preparation (on the basis of Annex VIII of the Ministerial Decree of 10 March 1998, the fire protection project of the fire risk assessment);

Request for renewal of Fire Prevention Certificate

In the context of D.P.R. 37/08 e D.M. 04.05.1998
    • Acquisition by the practitioner of the existing fire prevention certificate; intention to renew and request for Fire Prevention Certificate renewal ;
    • Execution of reconnaissance visits;
    • Drafting of legal paper technical expertise to be vowed and then forwarded to the Command of the Fire Brigade;

Design

Technical design of the following firefighting system typologies:
    • automatic fixed fire detection and fire alarm signal (UNI9795);

2)   Hazardous area classification for gas detection applications

3)   Design of gas detection systems (both combustible and toxic gases) based on engineering evalutation

4)   Verification of compliant installation (where required by the authority having jurisdiction)

5)   Retrofitting of automatic fire safety systems

6)   Site supervision and support to the installation team

7)   Project management for new fire detection and fire extinguishing systems

8)  Training on fire detection and fire extinguishing systems, both at our premises and on site.

Classification of a risk of explosion areas (according to NFPA methods or IEC);

SIL assessment of equipment and systems (IEC 61508);

Functional safety SIL and fire remote Telemanagement

The technological evolution and the increasing performance requirements of detection systems and automatic fire extinguishing have introduced two new features of the fire stations: functional safety sil systems and remote management of remote systems.

Why choose functional safety SIL

The safety integrity level (SIL) is a number indicating the value of the probability that a system is running correctly an instrumental safety function within a predetermined period of time. The SIL is assigned to each safety independent  function (SIF), made by one or more Safety Instrumented Systems (SIS).

It is a number between 1 and 4, where Safety Integrity Level 4 has the highest value and the Safety Integrity Level 1 has the lowest. In practice, the SIL is a quantitative measure of the probability that a given protective function is not performed if it had required the intervention, and allows the designer to reduce the risk of a dangerous situation and quantify the reduction.
