The first step of a water mitigation is for our technician once onsite is to perform a loss assessment. This is performed to collect the data needed to determine the extent of the loss physical structure and contents. An evaluation is determined and prioritize health and safety precaution for the residence and workers. The technician will determine which category the water loss is which can be a category 1, 2 or 3. The category 1 is a clean water loss that does not pose a substantial harm to humans. An example of clean loss is a broken water supply line, sink or tub overflows that do not have contaminants. A category 2 is called a grey water because the water contains a significant level of contamination as has the possibility to cause discomfort or sickness if exposed or consumed by human. An example of a grey loss is washer machine or dishwasher overflow. If a category 2 remains untreated for longer than 48 hours may change to a category 3. Black water is what a category 3 is referred to. An example of category 3 is a toilet backflow. This type of water loss indicated that structure materials and contents have been containment. It is important for the technician to determine the cause of loss to determine how the water loss is handled.
