These items protect for all to the body - potential exposures Respiratory protection regulations state that the employer must provide 1. 2. 3. - medical eval fit testing training as a minimum medical requirement, technicians performing water damage restoration services need medical consultation with their for appropriate immunizations - Primary health care physician The contract clearly states the agreement between the building owner and the restoration contractor. The form specifies who is responsible for payment and should be signed work begins - Before The technician's first responsibility when arriving at a water damaged sites is to identify, communicate and eliminate - safety hazards The most common safety hazards associated with water damaged structures result in and - slips and falls Federal regulations apply to the handling of based paint and asbestos - lead after safety concerns have been addressed and the initial water source has been stopped, the restorer must complete an evaluation of the water's migration through the Pre-existing conditions should be identified, documented and communicated to all parties during the initial inspection - Materially interested potentially affected the ultimate goal is to find the "edge" of water migration, which moves in a threedimensional path throughout the structure. This is accomplished across carpeted surfaces using a , and across most hard surfaces using a (non-penetrating) moisture meter. - moisture sensor non-invasive Water from a clean source with no substantial risk of causing sickness or discomfort is said to be water - Category one Water that has a significant degree of chemical, biological, and/or physical contamination and potential to cause sickness or discomfort is water - Category two When water intrusion results from a grossly unsanitary source or carries (disease causing) agents, it is said to be a Category 3 - pathogenic Worker and occupant and safety are the first priority on every sewage loss. Areas affected by Category 3 water intrusion are marked and posted as potentially hazardous - Health When resistance is encountered and performing proper services in a category 3 water loss become a challenge, restorers immediately and prevent liability - Stop Work Third party experts are commonly referred to as Indoor Environmental Professionals, or - IEPs Losses where regulated or hazardous materials have contaminated the structure do no change the of water - Category When carpet delamination (the loss of integrity in the adhesives used to laminate the and backing) has occurred, further damage is very likely. For this reason, when extensive carpet delamination is discovered, technicians must call it to the attention of all materially interested parties, document the condition and suggest - Primary Secondary Replacement There are a number of causes for carpet delamination - many of them related to restoration activities - Improper structure. During this process, the restorer inspects all areas - Cleaning procedures must be employed before the drying of a category 2 water loss can continue. At a minimum, affected must be removed and disposed of, and carpet must be thoroughly cleaned using a hot water extraction method - underlay Typical causes of carpet delamination are: 1. 2. 3. 4. - 1. Folding or Stretching when wet 2. Overly aggressive extraction 3. Improper removal of tack strip 4.Improper floating of carpet Hygroscopic materials gain and lose moisture continually in an effort to with the water content in the surrounding air mass. The more hygroscopic the material, the faster it will collect water vapor, and the easier it will suffer damage - Equalize Secondary Various cleaning and decontamination procedures must be used on category 3 water losses, including the removal of all materials affected by the water intrusion - highly porous many building materials will absorb excess water vapor and suffer damage, especially when air is allowed to remain above % relative humidity - 60% Abide by local and regulations when disposing extracted water. Waste water is best disposed of into a sanitary sewer - laws The primary goal of the initial extraction of the affected ares is to contain further of the water within the structure - migration whenever carpet must be disengaged from the tackless strip, a and carpet awl must be used - knee kicker the majority of cushion has a skin or mesh on the top side. the purpose of this skin is to ease during installation; it is not a vapor barrier - Stretching if the carpet is to be re-installed, technicians should avoid cutting carpet seams unless it is absolutely - necessary How many gallons of water are present in the basement that measures 13' X 20' where water is standing at a depth of 4' 5"? - 8,596.016 Gallons 13*20= 260
