Follow up on our Legionnaire’s disease prevention advice

 

 

 

With the recent outbreak of Legionnaire’s disease in multiple areas in New York City, we thought we would take a further look into the importance of temperature monitoring when it comes to Legionnaires prevention.

Legionnaire’s disease was first identified in 1977, following an outbreak at the American Legion convention in 1976, where the outbreak was theorized to have been caused by a faulty air conditioning unit. Since then, on average there are around 25,000 cases of Legionnaire’s reported each year, resulting in around 4000 deaths. Sadly around 75-80% of the cases are in people over 50 years old.

As we’ve mentioned before in previous blog posts, Legionnaire’s sources can include almost any water system and where water remains stagnant, e.g. plumbing systems and cooling towers. The World Health Organization recommends for building and facilities managers to keep hot and cold water systems clean and:

-Hot water should be above 122°F (which requires the water leaving the heating unit to be above 140°F)

-Cold water should be stored below 77°F, but ideally below 68°F

Alternatively, water should be treated with a suitable biocide to limit growth.

Legionnaires prevention

At Hanwell, we have a range of semi and fully automated systems and methods for monitoring temperature, with reporting and alarming systems.

By combining wireless monitoring transmitters and handheld thermometers with barcode scanning technology, monitoring water temperature has never been simpler. All temperature data can be downloaded to a central monitoring system, keeping your records up to date and alarm notifications can be sent by SMS and email 24/7, should any errors occur.

If you would like to find out more about how Hanwell systems can help you with Legionnaires prevention within your facilities, contact our Senior Business Development Manager, Meredith Paetz on 757-478-7557 or complete our enquiry form here.
