Important: Abrasive stones break down during mold and die polishing, grinding, tool sharpening, and dressing of cutting & grinding wheels. The resulting dust is classified by OSHA as inert or nuisance dust. Please consult the Material Safety Data Sheet for each stone; data provided therein pertains primarily to the dust produced during and after use. Please note that hazards may change when abrasive stones are used in conjunction with solvents, cutting fluids or other chemicals. For more complete information, consult the Material Safety Data Sheets of chemical products used with abrasive stone products.
Cut through the paper facing of the drywall sheet with a razor knife. Cut along the drawn lines. Break the drywall along the face cut, and fold the drywall slightly to make a crease in the paper backing of the drywall sheet. Cut through the crease in the backing paper with a razor knife from the backside of the drywall sheet, and remove the unwanted portion of drywall. To make cuts that are perpendicular to each other, use a keyhole saw for the shorter of the two cuts, and then fold and cut the drywall.
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, it’s important to have a working flashlight and turn off all water and electrical sources within the home, says Dr. Maurice A. Ramirez, author of “The Complete Idiot’s Guide to Disaster Preparedness.” Even if the power isn’t operational, it’s a good idea to go to your fuse box and turn off the main, plus all of the individual fuse connections. That way, if the power is reactivated, you’re not at risk for mixing standing water and electricity.
After a mold has been cleaned, repaired, changed over, and final-checked, it needs to be given a new status and moved to one of three areas—typically racked in holding/storage area, reset in the press, or staged as a back-up mold in a molding-cell operation. It could also go to an outside vender for rebuild or production. You should know where your molds are.
Our technicians are certified by the Institute of Inspection, Cleaning and Restoration Certification (IICRC), which is the hallmark of professional knowledge in the cleaning and restoration industry. You will be able to tell the difference: Rainbow International emergency water damage crews use state-of-the-art equipment and we employ Rapid Structural Drying techniques to dry your structure as quickly and completely as possible.
Drying - We determine the amount and type of drying equipment needed. Typically, we install a combination of drying fans, dehumidifiers, and negative air machines. We examine many factors (such as when the loss occurred, the magnitude of water damage, and size of the affected areas) to determine the best drying strategy to utilize as well as the quantity of equipment necessary. 
When a disaster of this magnitude occurs, the first things a plant will need are lighting and pumps. This requires the use of on-site generators and temporary power connections. It's highly recommended to not allow the plant distribution system to be back-fed. If a motor is required to turn a pump, a portable motor starter fed by the generator should be installed on a temporary panel next to the motor.
Repairing mold-damaged drywall is not difficult, but correcting the cause of the mold can often be challenging. Roof leaks, an improperly installed vapor barrier, leaky pipes, or constant contact with water from sinks, tubs, and showers can cause mold damage. Mold happens whenever moisture is constantly present. Mold spores attach to the paper facing of the drywall, the paper becomes a food source, and the mold colony propagates and grows. Long-term exposure to mold spores can be harmful, especially if a person is allergic to mold. You should consider consulting a mold removal specialist to determine the type of mold that is present, and you should always wear a face mask and gloves when working with mold.
Among the most common and most preventable causes of water damage are burst pipes. Burst pipes typically happen because of clogs and freezing. Prevent the damage by finding a family plumber to do annual inspections. Regular inspections and maintenance are a cost-effective, preventative measure. Installing new plumbing typically runs between $350 to $2,000.

HEPA air scrubbers remove contaminants from the air. This is an especially important piece of fire damage restoration equipment, as lingering soot particles can lead to health problems in a structure’s inhabitants after a fire. Commercial air scrubbers are also important in mold remediation when filtering mold spores from the contaminated environment. HEPA filtration ensures that even the smallest soot or mold particles are removed from the air.
