HEALTH & SAFETY


Increased wet deluge testing can exacerbate corrosion within pipework


and IG55, which are composed of naturally occurring gases which make up the atmosphere: nitrogen, argon and CO2


Tere are alternatives to discharging


testing and maintenance activities on assets.


VARIETY OF SOLUTIONS Te company’s systems range from gas suppression to fire-fighting foam and firewater deluge and it has been developing them to have a lower carbon footprint. For gas suppression, the firm avoids discharging systems to check enclosure leakage rates by undertaking integrity testing to ensure that fire- extinguishing concentrations will be held for the required time. With global warming being a key environmental issue now and for the future, Blaze promotes the use of inert gas systems such as IG541


– the latter being the by-product of other industrial processes. Te company also advocates the use of chemical suppression agents such as Novec 1230, which has a global warming potential of one and an atmospheric lifetime of only a few days. In 2015, the US Environmental


Protection Agency founded the PFOA stewardship programme for firefighting foam manufacturers worldwide to commit to the withdrawal of products containing fluorosurfactants having a carbon chain length greater than C6. Tis change has a significant impact


on firefighting foam users. Biodegradable synthetic-based fluorine-free products are now widely used. However, foam agents that do not contain fluorinated surfactants usually contain higher concentrations of hydrocarbon surfactants and solvents to compensate for the lack of film formation. Tis results in a more acute aquatic toxicity than the agents they replaced.


firefighting foam and when testing of foam producing equipment is required, Blaze recommends the use of test foams that do not have detrimental environmental impact.


THE ISSUE OF CORROSION Saltwater corrosion to oil rigs reduces the condition of assets considerably and this poses a safety and financial threat to operators. Currently in an offshore environment, deluge systems are tested by passing seawater through the system, which is sprayed over the equipment on the oil rig. Tis seawater causes accelerated corrosion of the equipment and the deluge system itself. Wet testing currently takes place anywhere between every six months to every five years, with older systems requiring more frequent testing than newer systems. Tis increased wet deluge testing exacerbates corrosion within the pipework, resulting in possible unplanned shut-downs to rectify the resulting damage. Frequent wet testing also increases
