If you don’t have an account, you can register now. HSG Part 1 is concerned with cooling towers and Part 2 is concerned with hot and cold water services. All of the documents may be downloaded from the HSE website.
The original L8 ACOP and guidance contained 61 pages whereas the new set of publications that replaced it amount to pages so there must be something new. The ACOP itself is little changed apart from the introductionwith most of the legionellz identical to the original. However, if you were complying with the intent of the ACOP beforeyou will almost certainly be compliant now.
There is also a desire ldgionella simplify the bureaucracy for very small businesses i. On the other hand employers must now provide information and training to all staff that might influence the risk exposure, not just those those appointed to carry out control measures. The previous guidance contained a basic description of the different types of cooling towers followed by a brief section on management, treatment and monitoring.
The authors would no doubt argue that maintaining a clean and efficient cooling system is a prerequisite to the successful control of legionella bacteria. However, much of legionellw new text is background information rather than legionellla guidance.
The new text mentions evaporative air cooling using evaporation directly or indirectly to cool ventilation air but then clouds the issue by suggesting that these systems may or may not require notification under the Notification of Cooling Towers and Evaporative Condensers Regulation.
However, as they have little in common with cooling towers it would have made more sense to include them in Part 3. The chapter on requirements of a cooling water treatment programme actually contain very few requirements or usable guidance other than Table 1.
Overall, the new elements of information and guidance relate to legione,la general operation of the cooling tower to reduce fouling and corrosion. Maintenance activity may legionelpa to be adjusted to meet the new guidance on fouling though it is likely that contractors following good practice would already comply.
Plant operators only need to ensure that their operating and maintenance regime for the cooling towers is sufficiently well documented to meet the requirements of the ACOP, both in terms of written procedures and the recording of tests and inspections. HSG Part 2 section 2 provides a more extensive description of domestic hot water systems than the previous guidance. There are several new guidelines that could increase maintenance and monitoring.
Of particular note are the requirements for increased monitoring of non-sentinel outlets on a rotational basis and legionells of sub-loop return temperatures in the domestic hot water circulation. There are also a couple of issues that have apparently been deleted such as cleaning water legionela and measuring the inlet temperature to TMVs. It is not clear whether these were intentionally deleted or lost in the editorial process so it p8 seem sensible to follow the original guidance.
HSG Part 3 is little more than a list of systems that may be encountered and draws from checklist 3 in the original guidance. There are some additional tasks associated with dental equipment but otherwise the scope and frequency of monitoring and maintenance is the same as previously. This does not mean that a risk assessment compiled according to the old guidance is invalid but it is important to regularly review any risk assessment, and consequent operating and maintenance procedures, on a regular basis and particularly when circumstances change or new guidance comes along.
