Water vapour measurements taken at the £16.5million Pathfinder House in Huntingdon between November 2012 and January last year revealed ­relative humidity routinely fell below the recommended level. The Chartered Institute of Building Service Engineers suggests a relative humidity of 60 per cent, while anything under 50 per cent could impact on peoples health. Further tests were carried out in August when 43 measurements were taken on nine days in the two buildings. The levels were higher than previously, but, according to a HDC Safety Advisory Group report, still cause for concern and often low enough to cause adverse health effects. Reporting to the advisory group in September, the councils environmental health officer Keith Lawson said action had to be taken to provide a comfortable working environment. Now the council is considering offering staff who report ­problems with humidity desk-bound humidifiers. Any further work looks to have been ruled out by the Chief Officers Management Team after three quotes were obtained but not acted on. It is thought the problem with humidity was discovered after an officer complained about their contact lenses drying out. Humidity had not been included in the original build specification. The minutes of the advisory groups latest meeting are due to be discussed at tomorrows (Thursday) HDC cabinet meeting.
