Successful Re-assessment of the GS01 SIL2 Certificate with Excellent Field History Data   27 Feb 2019

GasSecure is pleased to announce the recent successful re-assessment of the SIL2 (safety integrity level 2) certificate for the GS01 – the world’s first wireless infrared gas detector for flammable gases – by 3rd party assessor Exida. On re-assessment of the GS01 gas detector according to the IEC 61508:2010 standard, the products’ field history was analysed. This history is used to verify the failure rates as predicted by the initial FMEDA (failure mode effect and diagnostic analysis).

Launched in 2012 and SIL2 certified since 2015, the GS01 has now gained an excellent track record from thousands of devices installed. An estimate of the MTBF (mean time between failure) calculated from the service record of the installed base resulted in an MTBF of 192 years. This more than confirms the FMEDA estimate of 55 years and our promise: Wireless in design, safe in use. The GS01 remains the only wireless gas detector for flammable gases that is both SIL2 capable and carries the gas performance approval (per EN 60079-29-1) for Methane and Propane.

You will find our SIL2 certificate with corresponding documentation on Exida’s website (search for GasSecure).
