Zenova Group PLC announced that Zenova FX range of 6 and 9 litre extinguishers are now approved as marine equipment according to the Merchant Shipping (Marine Equipment) Regulations (MER) by BSI for use on onboard UK flagged ships and vessels. This latest designation follows on quickly from other important certification awards for the Group's extinguisher range in both the UK and Europe, for high-performance specification duty on both land and sea.
