Preventive Measures to Avoid Mould Contamination of Indoor Air
	The Durham District School Board in Ontario has recognized mould as a possible causative agent for poor indoor air quality. The Board believes that staff should not teach, nor children learn, in a mouldy environment. Preventive measures are followed to avoid mould contamination of indoor air in Durham schools. The following measures are taken in the Durham District School Board to prevent mould contamination of indoor air: 1.  Limiting carpet in new schools and additions. 2.  Removal of carpet and replacing with vinyl tile. 3.  Portable buildings are subject to an annual inspection. 4.  Portable buildings are subject to a biannual caulking program. 5.  Older style exhaust fans in portable buildings will continue to be replaced with Xpelair assemblies. 6.  Procedures are in place to report water leaks to the Facilities Services Department. 7.  Procedures are in place to report Indoor Environmental Quality concerns to the Occupational Health and Safety Department.
