Guyson International's Blast & Wash Division based at Skipton, England is registered to ISO 9001:2015 and ISO 45001:2018.

Mark Viner, Guyson’s Blast & Wash Division’s Managing Director, stated “The award of the ISO 9001:2015 standard, demanded a high degree of leadership commitment and is underpinned by having an effective quality management system in operation throughout the company. Guyson’s successful certification is testament to the positive engagement of our staff at all levels and demonstrates a clear aspiration to embrace the standard as a fundamental element of our customer-focused strategies and consistency of services.”

The latest BSI certification is the ISO 45001:2018 award for ‘Occupational Health and Safety Management’, replacing OHSAS 18001:2007 which Guyson's Blast & Wash Division had held for many years.

To support our environmental commitments and efforts we are currently working towards ISO 14001:2015 for our Blast & Wash division and using this standard as a benchmark for best practice throughout Guyson.

Guyson's Hose & Couplings division (based in Guiseley, near Leeds) is also certified to ISO 9001:2015.
