Flood Damage Clean Up


Water accumulated due to flood causes extensive damage to the flooring ad structure of the home and it is essential that the accumulated water should be removed as quickly as possible. If water has been stagnant on the structure for more than a few hours extensive damage will be caused. In most cases the floor and the walls that have been submerged by the water will be damaged. It is extremely vital to start the drying process throughout the structure. The best way to promote drying out of the interiors of the structure is through cross ventilation. To do this one has to open al the doors and windows facilitating maximum air movement throughout the room. One should also open closets that have been submerged in the water.

It is not advisable to use dryers or heaters to help the drying process since the same helps promote humidity in the structure and this will lead to the formation of bacteria and mildew. Rather one should turn on the fans and air conditioners. One should let the ventilation process till the interiors are totally dry. One can purchase a water meter that is available in paint and hardware stores to check the humidity level of the soaked surface.

A humid ground is the breeding place for bacteria and fungus. Once all the damaged materials have been removed one should wash down all the surfaces using disinfectants. The bleach that one uses in the household is best suited for this purpose and the same will help one you to get rid of mold and mildews and will also prevent them from growing too. Strong bleach in the ratio of 5:1 (five parts of water to one part of bleach) is recommended and the same can be sprayed using the standard garden sprayer. One should be adequately protected and should wear goggles and face mask along with rubber gloves. Do not use the bleach on fabrics since it might discolor them and even damage the fabric. Some items like mattresses that are totally soaked cannot be recovered and it is best to dispose them.

There are some precautions that one should follow when working in areas that have been inundated with contaminated water and these should be carried out only when there is no standing water left in the house. If your vaccination is not up to date, take a tetanus shot. Electric supply should be turned off from the mains before one enters the house to avoid electrocution. Get the wiring tested from a certified electrician before turning on the power. One should also check that all the gas appliances are turned off and that the main valve of the pipe supplying the gas is turned off too. One should try to avoid direct contact with the contaminated water too. Keep an eye out for insects and small creatures. These get displaced from their natural habitats when flood occurs and tend to flow with the flood water. Hence it is recommended to check out for them throughout you home, especially in corners, cabinets and dark spaces.

Clean Room Controls, Design and Other Variables


A clean room is an environment that is used for the manufacturing of precision equipment or conducting of scientific research that has a strictly controlled level of contamination. Clean rooms use specifically designed equipment to control the amount of particles per cubic meter at a specified particle size in the room. In some cases even air temperature and humidity controls are needed.

Air Filtration

Regardless of cleanliness class, the air to all clean rooms is filtered thru HEP (High Efficiency Particulate Air) or ULPA (Ultra Low Particulate Air) filters. These filters are rated for 99.99 percent efficiency on 0.3 micron particles (HEPA) and 0.128 micron particles UULPA). Cleanliness is a function of how much clean air is mixed with the contaminated air in the room. The more clean air, the greater the contaminant dilution, and the higher the level of cleanliness. Clean rooms also take advantage of another feature of the filters and that is the pleating of the media in the manufacturing process. This pleating effect causes the air passing thru the filter to be delivered in a jet stream. The collective results of these multiple air streams produces a column of clean air moving uniformly away from the filter face.

Temperature Control

The process within the space generally dictates the temperature range that can be tolerated. If there are non-specific requirements, the human factor usually will guide the selection.

Humidity Control

Often overlooked in the design of a clean room is the stringent humidity requirement. This can vary, again depending on the process involved. Between 40 percent to 60 percent is typical with a variation usually not greater than 5 percent.

Walls

Walls can be constructed of any non-shedding material that can be wiped down easily and kept clean. Walls can be gypsum board with a seamless coating on metal studs or they can be modular. Modular walls have a tax advantage in they are considered tangible property and can be taken down and moved.

Floors

The best clean room floors are poured seamless systems, seamless sheet vinyl, epoxy, or vinyl tile in that order. Products that limit dust penetration and can be easily maintained are required.

Ceilings

Most clean rooms are designed with positive pressure plenums, or ceiling spaces. This requires a special grid system that is usually factory gasketed or it can be a gel system on the more stringent rooms. The grids typically support the HEPA filters, lights, and panels and can weight as much as 12 pounds per squire foot. 12 gauge wire is used to support the grid.

HEPA Filter Units

The heart of any clean room design is the filtration that is required. Some are ducted but the most common are fan powered units. The typical 2' x 4' unit has a capacity of 700 to 800 cfm, with a 1/3 hp motor. Latest designs also include energy efficient watt motors.

Clean Room Lights

Lights are specially constructed for clean rooms so they are sealed air tight. They also produce heat which must be taken into account. Typical lighting is 70 to 100 foot candles.

Variables

While we know what the hardware mentioned above produces in regards to release of microbes, heat etc., the one element that changes daily is human element. It has been said that "absolute cleanliness" cannot be maintained with man's involvement, that robots are the only way to eliminate this source of particulate pollution. Even fully gowned, workers are constantly shedding skin particles. Gowning is required.

Gowning

Garments can include hair covering, beard or mouth covering, body covering, shoe covering and gloves with any combination of the above. Garments should be put on in a gowning room. This room should also be HEPA filtered.

Testing and Certification

Once the room is completed, most specifications call for testing and certification. Some requirements state that the room should be test annually also. Testing is usually conducted by an independent testing agency using the ISO Standards. It is also imperative for the owner to purchase a clean room monitor in order to determine the daily status of the room.

Lab Equipment for Clean Rooms and Critical Environment


There are some facets of medicine, industry and scientific research where there is a need for an environment as completely free as possible of any outside pollutants or substances that could bring in unwanted factors or variables to whatever procedure is being investigated, developed or operated on.

For this purpose, laboratories with critical environments called 'clean rooms' have been developed. There are a huge variety of types of facilities and apparatus and clothing designed and available for a very wide range of research and control laboratories. Cole-Parmer stocks the equipment you need for a clean room as well as all the usual laboratory equipment and all the glassware you require.

A clean room's level of contamination has to be a controlled one, with a specified level of contamination, which is the number of particles per cubic meter. For instance, the air in a typical urban street contains approximately 35,000,000 particles per cubic meter.

An ISO 1 clean room may have no particles at all of a size above 0.5 microns, and only 12 particles per cubic meter or smaller than that.

The critical environments developed may be as large as a whole huge factory premises manufacturing sensitive foods or materials, biotechnology, electronic technology, medicines, or they can be as small as a pre-term baby's incubator. Obviously, the degree of sterility will vary greatly.

Some 'clean rooms' may be moderate, such as an ICU hospital ward where all instruments and equipment is sterilized but protective clothing may be limited to a face mask and sterile gloves. In an operating theater, sterile gowns, foot and head coverings are usually added. The room is generally isolated from entrance by anyone who is not involved in the actual surgery or medical procedure.

In very critical environments, more sophisticated clothing is sometimes worn, even to the extent of helmets and separate breathing apparatus. Cole-parmer have a range of protective clothing, pro-clean overalls, gloves, head and foot covers, and masks to prevent contamination.

Everything inside the clean room is sterilized and/or decontaminated. Even cleaning materials and tools are specialized for use inside the controlled environment, and kept sterile. Cole-Parmer supply all the necessary specialized cleaning agents, mops and brushes you need. Airflow, filtration, air pressure, humidity and temperature are generally also controlled.

The entrances and exits are where the highest precautions are normally taken, with a 'gray room' where clothing is changed before entering a vacuum chamber, air lock, or air shower, where even the sterile clothing is decontaminated before entrance into the clean room itself. Cole-Parmer provide extremely useful layered adhesive-coated mats that capture dirt and dust so you don't track it into the clean room. When the top layer is dirty, you peel that layer off to expose a fresh surface underneath.

As you can see, there is a whole industry devoted to the production of conditions for sterility and decontamination, ranging from architecture, building and engineering, to protective clothing manufacture, as well as machinery, apparatus, tools and equipment. You will find most of the apparatus and equipment you need at Cole-Parmer specialists.

How to Clean Up After Water Damage and Do I Need a Professional?


Within minutes..

Water spreads quickly to additional areas, rapidly increasing the scope and cost of the loss. Stains from furniture can dye carpet permanently. Paper goods are damaged by moisture absorption and warping.

Within hours...

Furniture in direct contact with water swells or splits. Drywall swells and disintegrates; paneling warps. Odor becomes an issue.

Within days..

Mold develops, along with the characteristic "musty" odor. Sensitive components in pianos and organs swell and malfunction with elevated humidity. Metal surfaces begin to corrode. Doors and window casings swell and distort or delaminate. Wood decking, joists and studs begin to swell, warp and split. Electronic components malfunction due to moisture condensation. Allergic reactions escalate.

Within weeks..

Mold discolors and destroys organic materials (jute backings, paper coverings on drywall, paneling, wood). Structural wood warps and splits, while chemicals in wood dissolve and discolor or destroy finishes. Costs escalate dramatically as the requirement for gutting the structure and replacing components becomes necessary. Health hazards are everywhere. Building Occupants may be required to leave their property due to safety and health hazards. Children & the elderly are at higher risk due to weaker immune systems

This is an incredibly technical field of study with constantly evolving technologies that allow professionals to dry buildings completely within 2-3 days with little or no demolition with CLEAN WATER. Typically water damage is far more progressive than what is visible without special tools (thermal cameras, moisture meters and hygrometers are crucial).

Any water other than category 1 "clean" water has completely different protocols and major health hazards will likely be present (and made worse) if the steps needed are not taken. There should be no need to "disinfect" carpet in a clean water loss. You cannot truly sanitize a porous surface such as carpet and you do not need to apply chemicals if the water is from a clean source and dried within 24-48 hours (thorough cleaning is all that is required). In states such as Maine if a company applies disinfectants or antimicrobials they need to be a licensed Master pesticide applicator or risk stiff fines.

To dry carpet, sub floor, hardwood & walls QUICKLY WITHOUT MOLD requires very specialized equipment(often a heat drying application), a sound understanding of temperature/humidity control and moisture meters to measure moisture content to verify that materials have been dried properly. These situations should only be handled by a certified, highly experienced technician.

Time is a huge factor and MANY water damage situations do not require professional help. If there is concrete flooring with glue down carpet, or floor tiles over concrete with little or no wall damage with clean water then a person can certainly handle their own water loss with the right equipment, desire and a little training.

To dry a structure with sub floor, drywall, padded carpet, plaster, hardwood floors, behind cabinets, in a crawlspace or large area it could very well mean permanent loss of property value, refusal of insurance coverage and serious health risk to occupants.

Reputable contractors warranty their work for at least 3-5 years, have liability and pollution insurance, hold IICRC certifications, provide a thorough water damage report when work concludes (we provide a 25 page report documenting everything that takes place including all of the temperature, humidity and moisture readings), have good references and yes will charge for their services like any other professional. The Better Business Bureau is a good resource as well.

Like any professional, liability is a huge factor, the average company will likely have several hundred thousand dollars in specialized equipment, a team of certified professionals with years of experience and tools to determine (and show you) the extent of damages both visible and hidden.

And lastly, there is a reason insurance companies suggest calling in a restoration firm. And not because they want to spend thousands of unnecessary dollars. It is because we save them thousands and thousands of unnecessary dollars. These savings come from rapid drying which can prevent the need for demolition, preventing mold growth, preventing bacterial development, preventing law suits and getting the home owners back in the area quickly and safely.

Another major factor is documentation and warranties. When a property is sold you must disclose water losses or risk major law suits. When handled properly by professionals this is no problem. You have the documentation and we are only a phone call away.

In Summary yes, many small water damage situations do not require the cost of professional restoration firms. However when needed we can be an invaluable resource to you in your time of need.
