Hepatitis A vaccination for Hyperbolic cooling tower cleaning
Rank: Guest

Posted By hogben
Some of my colleagues are engaged in cleaning a hyperbolic cooling tower that uses river water as coolant. One of them has suggested that vaccination for Hep A is required. As a microbiologist I disagree because raw sewage is not dumped into the river and therefore risk assessment suggests it is not necessary. If it were, anyone exposed to river water would require it. Does anyone disagree? Thanks for your help

Not a very common virus and not very serious. Risk of catching it from river water is negligable unless, as you say, raw sewage is being pumped into the river. I think you also have to drink the water to become infected. I would agree that protection is not required.
In cooling towers I would be more wary of Legionella and I take it you have a protocol to deal with this?

Our specialism is legionella control so I certainly hope so. It is less of a problem in hyperbolics that use once through cooling but still a risk
Thanks
