CO₂ Extinguishing Systems with SIL 2 Certificate – Fire Protection for Power, Petrochemical and Process Engineering

Rosenbauer Fire Protection has used the international SIL 2 certification since 2011 and all of the tried and tested CO₂ extinguishing systems therefore meet the special safety requirements in power plant operation and in process engineering. The extinguishing systems are certified for risk classes up to SIL 2 and fit as an integral component in the security concepts of entire systems. The corresponding systems have been developed and installed for clients such as MAN, Kawasaki, Ferrostaal and Atlas Copco.

WATER EXTINGUISHING SYSTEMS

Water-based fire extinguishing systems
make up the largest share of the
extinguishing technology – in case of
sprinkler systems a simple and reliable
technology for decades.

GAS EXTINGUISHING SYSTEMS

The extinguishing effect of inert gases is
achieved by displacing the oxygen in the air.
Assets are protected by the slow response
that is typical of the inert gases CO2,
nitrogen and argon.

SIL 2 is the Key to the Responsibility of the Plant Operator

Statutory Regulations concerning SIL 2

The best possible state of the art security requirements are required by law in most countries. It is up to the operator to decide how to achieve the required degree of safety through practical solutions.

The objectives are often individual developments with a focus on the economic needs of the business. This increases with customisation of the solution but also the individual’s responsibility.

The normalization via the „Safety Integrity Level“ (SIL) however has the advantage of an internationally standardized assessment of protective equipment, defined life cycle management with the documentation of function-related development sections and a comprehensive assessment of the entire protective equipment. The classified and rated CO₂ extinguishing systems from G&S contribute greatly to the safety of people and the environment and to protecting investments.

Rosenbauer CO₂ Extinguishing Systems up to Safety Integrity Level 2

Rosenbauer and its CO₂ extinguishing systems offer a certified fire protection system that can easily be used in safety-related systems. The concepts and methods of IEC 61508 apply to all of the important steps and components.

In a first step, the requirements are agreed with the customer. The SIL standard defines the parameters here that the customer must provide for the planning and implementation of activities. These figures provide the classification results from SIL 1 to SIL 4. The engineers at G&S Group then develop and define the appropriate fire protection system from fire detection to triggering extinguishing.

The monitoring is undertaken by verifying the individual design and manufacturing steps. The validation has already been provided by TÜV Rheinland. A complicated, individual, external check on each plant is therefore no longer necessary up to SIL 2. In the Rosenbauer plant in Mogendorf, the system is then built and tested before it is installed for the customer by an Rosenbauer assembly team. Regular maintenance by Rosenbauer service technicians is an integral part of the SIL certification and guarantees the safe operation of the plant for life.

MINIMIZING THE RISK
IS DEDICATED MAINLY BY:

Definition and assessment of risk by detailed probabilities of the failure of the sensor to the actuator
Definition and implementation of measures to reduce the residual risk
Use of rated or certified devices
Regular testing of correct operational function

Risk-reducing measures are divided into four levels from SIL 1 (low risk) to SIL 4 (very high risk). The demands on the measures to reduce risk and the components used rises with the risk.

Functional Safety by SIL 2

The goal is to ensure the functional safety as part of the overall safety of the systems and machinery. This depends on the correct functioning of the risk reduction systems.

Proper safety functions must be performed under defined error conditions and with a defined high probability.

With the requirements of the international IEC 61508 standard, it now calls for a quantitative verification of the residual risk for the entire protective device consisting of sensors, controllers and actuators.
