Humidity a concern for electrical contractors 

Data showing spiking humidity levels on construction sites are a growing concern for electrical contractors working in the sector, according to a new report from temporary power company, Aggreko.  

The report reviews data from World Weather Online to compare mean relative humidity levels in the UK’s construction hotspots, showing an average of around 76% – well above the recommended levels of between 40-60% on a construction site. 

With a rise in humidity comes a rise in moisture which is infamously known for causing issues on electrical installations. With this pressing concern in mind, Aggreko’s new campaign, ‘The Hidden Cost of Humidity on Site,’ is aiming to generate awareness of issues surrounding temperature and moisture control. 

Those managing electrical risk during refurbishment work are being alerted to the fact that if the atmosphere on site is not controlled effectively, moisture, in the form of water vapor, can find its way into the smallest areas and spaces of any components. This in turn can leave corrosive deposits behind that continue to cause damage after drying.
