Legionnaire's disease
The health and hygiene-related criteria established by Royal Decree 909/2001, article 2, inform us of areas of application of prevention and control of Legionnaire's disease through the adoption of health and hygiene-related measures for installations that can transmit legionnaire's disease.
Air-conditioning ducts are included in the areas of application, and according to article 6 and 7 of the Decree, we should bear in mind the risk of contracting an illness even when adequate preventive measures and pertinent maintenance programs are followed.
