The current ACoP L8 publication is in 2 parts. Part 1 is an ACoP and provides advice on complying with legal requirements concerning the risk from exposure to legionella bacteria. Part 2 provides technical guidance on the control of legionella in water systems.
The ambien no prescription proposal is to revise Part 1 and to remove part 2, and make it available separately as a revised technical guidance. Both parts will be published by the end of 2013.
