It’s important to understand the differences because Category 2 and Category 3 water present health risks to your employees and customers and need to be handled differently. The most likely sources of clean water would be water from a pipe, water heater, steam lines or even rainwater. The basic rule of thumb is that it should look and smell like tap water.
Many parts of a car are challenging to clean and dry because they are hard to access. Door locks, window regulators, power seat motors, heating and air conditioning components, and many small parts are tucked away in enclosed areas or up under the dash. These items may work okay immediately following a flood, only to fail later due to contamination by dirty water.
Fire and Water Restoration companies are regulated by the appropriate state's Department of Consumer Affairs - usually the state contractors license board. In California, all Fire and Water Restoration companies must register with the California Contractors State License Board.[10] Presently, the California Contractors State License Board has no specific classification for "water and fire damage restoration."
After you learn how to remove mold, you’ll want to prevent it in the future. The key to stopping most mold is to control dampness. The worst infestations usually occur in damp crawlspaces, in attics and walls where water has leaked in from the outside, and in basements with poor foundation drainage. Stopping leaks, ensuring good ventilation in attics, keeping crawlspaces dry and routing water away from the foundation are the best defenses on how to get rid of mold.

Inspect the defects. To find the source of the defects, we perform a visual inspection as high as 24x magnification, use dye-penetrant inspection (DPI), or use fluorescent penetrant inspection (FPI). This allows us to find small pits, microscopic cracks and larger cracks in the gate. If these defects are not identified and repaired, more problems can arise for the gate and the mold.

The first order of business in assessing water damage to the electrical equipment in any industrial plant is to gather all pertinent drawings and documentation available and perform a walkthrough of the entire electrical infrastructure. However, at times, drawings and documentation may not be available due to destruction (Photo 1). In this case, walkthroughs must be performed through tribal knowledge of plant personnel. Keep in mind the initial assessment is preliminary in nature, and an absolute understanding of the damage will not be gained until the equipment is disassembled in its entirety.
Locate and repair the source of the leak. The source of the problem is usually apparent once you remove the drywall and expose the framing. If the leak source is not easily determined, consult a licensed contractor before you replace the drywall. You must repair the cause of the leak or mold and mildew will eventually reform over the new drywall. An unresolved leak may also create additional damage to framing, insulation, siding and flooring.

Assessing the severity of the damage is important for determining what is needed to start water damage repair and water removal. There are several different categories assigned to water damage. Category 1 refers to clean water, or water that does not pose a threat to humans. Possible causes of this type of damage include broken appliances or sink overflows. Category 2 water is also called gray water. This means that the water is contaminated and may cause sickness of ingested. This type of water contains microorganisms. Broken toilets, broken sump pumps, and seepage may cause category 2 water damage. Category 3 water is known as black water. This type of water is unsanitary, as it contains bacteria and other organisms that cause sickness. The possible sources of black water damage include sewage problems and contamination of standing water.

In addition to the obvious damage it does to upholstery and carpeting, floodwater is a corrosive and abrasive mixture of water and dirt that works its way into every seam and crevice of a vehicle. Sewage and chemical contaminants may also be present in floodwater, and in coastal areas salt water from ocean storm surges can increase the possibility of vehicle damage and costly auto repairs. Even if a car is mechanically safe to drive, sanitary concerns could make it unwise for you to do so.
Air movers help to ventilate the affected area, circulate air so that the moisture can be extracted by dehumidifiers and dry damp materials such as drywall and floors.
