Contamination: An Interruption That Means Business
Even a small fire can cause smoke contamination throughout a much larger area, including as the result of spread through sealed doors in some circumstances. Water damage related to fire-fighting activities can also cause mould to contaminate and damage stock as well as the building structure.
