Schools can learn from temperature monitoring technology

Schools can learn from temperature monitoring technology

Schools need to keep on top of maintenance and repair costs and keep their buildings in the best possible condition to help children fulfil their potential. This is where being forewarned is being forearmed, says Derek Richardson, an environmental manager for Ellab Monitoring Solutions Ltd (formerly Hanwell).

School’s out for summer

In addition to normal times when schools are usually closed for weekends and holidays, Covid-19 and the subsequent lockdowns and restrictions have added to the challenge of maintaining classrooms and learning facilities when the lights are out and all the pupils and staff are at home.

Intermittent occupancy resulting in sporadic heating and ventilation encourages moisture to evaporate and condense in a school structure. Reacting swiftly to catch leaking pipes or water coming in from outside is vital, especially for buildings that are often more exposed to weather and may be attended less frequently.

As we know many school buildings are part of our historic heritage but their age makes the inspection and maintenance of drainage systems particularly difficult. Water coming through roofs due to blocked gutters and downpipes can soak into timbers and framework causing potentially hundreds of thousands of pounds worth of damage. Compare that to the tiny cost of putting modern monitoring systems in place.

Canteen hygiene

Then there’s the strict hygiene requirements for canteens, ensuring that fridge and freezer stock are not subject to potentially dangerous temperature variations or even equipment failure. Automated wireless monitoring systems provide real-time tracking of the environment in which food is kept – and could save the day in the event of incidents such as power cuts, fridge failures or doors left open.

Early detection can help nip potential problems in the bud. The last thing canteen staff need on returning to school is to lose valuable stock because of temperature fluctuations caused by dodgy conditions or faulty fridges. Food safety is paramount so why leave your stock to chance.

Wireless solutions are flexible so you can easily move or expand the number of sensors to ensure they are always in the optimum positions, and provide continuous output for consistent and accurate readings, wherever you are.

We recognise that a school canteen needs product reliability as much as any other food outlet. Our Notion Lite system provides accurate, wireless real-time monitoring 24/7 for fridges or freezers.

Notion Lite records and stores a critical log of historical temperature data, sends out warnings to multiple users and triggers an audible alarm day or night whenever any user-set thresholds are exceeded, providing ultimate peace of mind.

Teaching best practice

In fact, the latest monitoring systems can also gather data to give head teachers information on what they might need to do to improve the environment within the school.

The key thing is to react swiftly to environmental changes which can be triggered by temperature fluctuations and increasing humidity levels. Undetected flooding or leaks can cause irreparable damage from the top to the bottom of schools. So, an early warning system can prevent interrupted learning time and financial implications.

Reducing the risk of an outbreak of Legionnaire’s disease within water systems can best be achieved using temperature monitoring and control. As Legionella thrives between 20?C – 45?C best practice should be to ensure the following temperatures are maintained at all times – hot water stored above 60? while cold water should be kept below 20?C.

Top of the class

Manual monitoring and checking of environmental conditions in high-risk systems such as water tanks and wash rooms where Legionella can thrive are time consuming, laborious and open to error. Monitoring systems supplied by the likes of Ellab makes preventative measures a breeze.

Hard to access areas can be monitored with wireless sensors that measure pipe and tank temperatures as well as flow using non-intrusive ultra-sonic clamps on flow meters. Places such as wash rooms and shower facilities can be fitted with inexpensive thermocouples linked to a junction box where the data is easily accessed by a handheld device. Alarms are generated from both the wireless sensors and handheld readings alike and can be sent directly via SMS to mobile devices or desktop PCs.

It is estimated there are over 5,000 listed school buildings in England and they face a variety of environment-related challenges which can result in damage to vulnerable areas and contents. Embracing flexible and reliable monitoring equipment to warn of possible problems offers the best possible protection for learning facilities and their students.
