Water Damage Categories
This is part 5 Of 5 part series. (Yes, there is that much to say about mould!)
Water originates from a sanitary water source and does not pose a substantial risk from dermal, ingestion, or inhalation exposure.
Examples of Category 1 water include broken water lines, melting ice and snow, broken toilet tanks or bowls, or tub and sink overflows that do not contain contaminants or additives.
Category 1 water may become Category 2 or 3 water for numerous reasons including coming into contact with building materials, and mixing with soils or other contaminants. Odours can also signify that Category 1 water has deteriorated. In addition, the age, type and history of the building as well as the general housekeeping can affect Category 1 water.
Water contains a significant amount of contamination and has the potential to cause discomfort or sickness if contacted or consumed by humans.
Category 2 water can potentially have unsafe levels of microorganisms or nutrients available for microorganisms to flourish and chemical or biological additives.
Examples of Category 2 water include discharge from dishwashers or washing machines, overflows from toilet bowls on the room side of the trap with some urine but no faeces, broken aquariums and waterbeds. For the same reasons stated for Category 1, Category 2 water can deteriorate into Category 3 water.
Water is grossly contaminated with pathogenic, toxigenic or other harmful agents.
Examples of Category 3 water include sewage, toilet backups originating beyond the toilet trap, ground water and water from weather related events.
Water damage is a serious issue and can pose severe immediate risks. Quick remediation of water damage will assist in the prevention of mould growth, however based upon the category list above make sure that a professional contractor or environmental consultant is consulted.
