Five year replacement recommendation.
MUREX WELDING PRODUCTS is reminding users that Pressure Regulators and Flashback Arrestors contain elastomeric components which deteriorate and cause the units to fail in service. Pressure Regulators used in 'low wear' situations such as educational establishments, laboratories and similar applications are particularly prone to failure. Indeed a number of very serious incidents have occurred as the usual result of an elastomeric component failure is a large discharge of gas from the over pressure relief valve. In response to the need for industry safety, the British Compressed Gases Association recommended in their Code of Practice 7 that Regulators and Flashback Arrestors be replaced or refurbished after 5 years in service or manufacturers recommendation. This is an excellent recommendation and has been widely adopted by industry.
