Managing the risks of Legionella

Every employer is responsible for controlling the risks from a range of hazardous substances in order to ensure the health, safety and welfare of its employees. Legionella bacteria is one such hazardous substance which is potentially fatal. By their very nature, emergency safety showers and eye washes possess certain traits that pose a risk factor.

What can I do to reduce the risk of Legionella bacteria within my safety shower and eye wash equipment?

Weekly activation: an essential task recommended in international and European standards. Not only can you check that your equipment is functioning properly, but the activation will also flush the pipes of any sediment and decrease the risk of stagnant water in the system.

Monthly: Inspect water storage tanks.

At least quarterly: Clean and disinfect shower heads, nozzles, roses, ‘Y’ strainers, and water storage tanks.

At least every six months: Flush through and purge to drain ensuring three to five times the volume of water in the stagnant zone is drawn off.

Regular servicing: Hughes recommends emergency tank showers are emptied, cleaned, and refilled with potable water every six to twelve months. Book a regular service of your safety equipment via the Hughes service team for complete peace of mind.
