Industrial Premises

In addition to offices, industrial premises may contain manufacturing processes which involve water either in storage tanks or for cooling or spraying.

If any of the process water has a temperature between 20°C – 45°C, then legionella bacteria can proliferate. The risk become greater if the process is intermittent, greater still if a cooling tower is used.

The risk becomes greater where working conditions are hot or dusty, drinking water coolers can quickly become fouled and should undergo regular testing.
