Standard Procedures

Equipment Application Guidelines

Dehumidification Application Guidelines

The following method can be used to determine the amount of dehumidification, either conventional refrigerant, LGR refrigerant or desiccant, to dry a structure after water damage. These guidelines are based on the IICRC’s S500 standard version 3.

1. Determine the volume of the area that is water damaged and can be isolated from other open areas. Length X Width X Height = Cubic feet of space where dehumidification is required 2. Determine the Class of the Water Damage.

Class 1 (least amount of water, absorption

and evaporation)

Water damage restoration projects that affect only a part of a room or area; or larger areas containing materials that have absorbed minimal

moisture. Little or no wet carpet and/or cushion are present.

Class 2 (large amount of water, absorption

and evaporation)

Water damage restoration projects that affect at least an entire room of carpet and cushion (pad). Water has wicked up walls less than 24 inches. There is moisture remaining in structural materials (e.g., plywood particle

board, structural wood, VCT, concrete and substructure soil).

Class 3 (greatest amount of water,

absorption and evaporation)

Restoration projects in which water has wicked up walls greater that 24 inches, or it enters from overhead affecting the ceiling , walls, insulation,

carpet, cushion, and subfloor. The entire area is saturated.

Class 4 (specialty drying situations)

These consist of wet materials with very low permeance/porosity (e.g., hardwood, plaster, brick, concrete, light wet concrete and

stone).Typically, there are deep pockets of saturation, which require very low relative and specific humidity for drying.

(36)

For LGR Refrigerants divide the cubic footage by the following factors:

Class 1 Cubic footage / 100

For Desiccant Dehumidifiers multiply the cubic footage by the following factor, then divide by 60:

Class 1 Cubic footage X 1 / 60

The result of this calculation will let you know how many CFM are needed on this job.

It is often necessary to use more than one dehumidifier to make up the required CFM for the desired

number of air changes. Moisture Mapper has entered the industry standard equipment ratings into the

(37)

TES Thermal Drying Systems Application Guidelines

The following method is used to determine the amount of equipment that is required when using the TES heating method of drying:

TES 250K and the TES 200K (thermal energy system units) are boilers that are placed outside of the structure, and can power up to six boxes. Each 200k TES can power five TEX boxes.

TEX (thermal exchange boxes) are the exchangers (boxes) that are put in the structure along with a fan. The application rate is as below:

Each TES with five TEX boxes. It can cover up to 1250 square feet for WFD direct containment and up to 40000 cubic feet uncontained.

For carpet containment: Each TEX covers one carpeted area from 100-250 square feet. The carpet must float completely without flapping.

For direct plastic containment of hard surfaces: Each Tex covers from 100-300 square feet.

For open areas that are not directly contained: Each TEX covers 8000 cubic feet when combined with heat from HVAC system, but cannot be considered WFD set up this way.

(38)

Air Scrubber Application Guidelines

An air scrubber captures removable airborne particles and traps them in a disposable HEPA filter. With an activated carbon and potassium permanganate blend absorption filter, a wide range of odors can also be removed.

Air scrubbers should be used on water damage restoration, demolition and construction projects where airborne contaminants such as mold, mildew, or other particles are present.

A general rule for the application of an Air Scrubber is a minimum of four air changes every hour, or one air change every fifteen minutes.

Using a typical air scrubber that provides 1400 CFM of airflow per minute, the following provides a method for determining the number of units that are required.

1. Determine the volume of the area that requires an air scrubber and can be isolated Length X Width X Height = Cubic feet of space where the air is to be cleaned

2. To determine the amount of air flow that is required, take the cubic feet of the space and divide by the number of minutes desired for an air change:

For one air change every 15 minutes, or four air changes per hour

Cubic feet of space to be scrubbed / 15 minutes = CFM of Air Scrubbers Required 3. It is often necessary to use more than one air scrubber to make up the required CFM for the desired

(39)

Air Mover Application Guidelines

The number of air movers required is often subjective, but can be estimated based upon the area to be dried. As a rule of thumb, the more aggressive the air movement, the greater the rate of evaporation assuming that the air in contact with the surface to be dried can hold additional moisture.

The air should be aggressively moved throughout a room in a circular pattern with additional upward movement to prevent stratification, or layers of untreated air. Specifically, the air should be directed across floors, walls, ceilings and contents in order to accelerate the evaporation of moisture at the surface of the material to be dried. This circular motion should then be concentrated on specific areas to be dried, Particular attention should be paid to areas that may be isolated from the normal circular motion of the air, i.e. window bays, closets, smaller rooms, voids, floor ducts, etc. Each one of these areas should be checked to ensure air movement.

The following general rules can be used for determining the number of air movers required:

Standard Investigation Guidelines

Investigation Procedures

A loss assessment of water damage at 20935 State road 19, Cicero, IN was performed using standards and procedures as established by the IICRC S500 (Institute of Inspection, Cleaning and Restoration

Certification Standard) and other industry standards as appropriate.

The actual procedures that were used are based upon reliable restoration principles, research and practical experience, trade associations serving the professional disaster restoration industry, chemical formulators and equipment manufacturers, cleaning and restoration training schools, the insurance industry, the scientific and health services community, and others with specialized experience. The collection of data included a thorough on-site inspection of the facility using environmental temperature / humidity and moisture content instrumentation; interviews with the property manager and tenants; a review of documents and drawings of the structure; and an on-site inspection of a similar building located on the same property. A standard for temperature / humidity levels and moisture content of materials was established.

A categorization of the level of contamination of water was established at category 1 .

Category 1 water is referred to as "Clean Water". Clean water originates form a source that does not pose substantial harm to humans. Examples of clean water sources may include, but are not

necessarily limited to, broken water supply lines, sprinkler systems, tub or sink overflows with no contaminants, appliance malfunctions involving water supply lines, melting ice or snow, falling rainwater, broken toilet tanks and toilet bowls that do not contain contaminants or additives. Note that clean water that has contact with structural surfaces and content materials may deteriorate in cleanliness as it dissolves or mixes with soils and other contaminants, and as time elapses.

Category 2 water is referred to as "Gray Water". Gray water contains a significant level of

contamination and has the potential to cause discomfort or sickness if consumed by or exposed to humans. Gray water carries microorganisms and nutrients for microorganisms. Examples of gray water sources may include, but are not necessarily limit to, discharge from dishwashers or washing machines, overflows from washing machines, overflows from toilet bowls with some urine (no feces), sump pump failures, seepage due to hydrostatic pressure, broken aquariums and punctured water beds. Gray water may contain chemicals, biocontaminants (fungal, bacterial, viral, algae) and other forms of contamination including physical hazards.

Time and temperature aggravate category 2 water contamination levels significantly. Gray water in flooded structures that remains untreated for longer than 48 hours may change to category 3 - black water.

Category 3 water is referred to as "Black Water". Black water contains pathogenic agents and is grossly unsanitary. Black water includes sewage and other contaminated water sources entering or affecting the indoor environment. Category 2 water that is not removed promptly from the structure may be reclassified as category 3 water. Toilet backflows that originate from beyond the toilet trap is considered black water contamination, regardless of visible content or color.

Category 3 water includes all forms of flooding form seawater, ground surface water and rising water form rivers r streams. Such water sources carry silt and organic matter into structures and create black water conditions. Additionally, the water is considered to be category 3 water in situations where structural materials and/or contents have been contaminated with such contaminants as

(41)

Following the removal of standing water, a detailed inspection was conducted that considered the extent of water migration, the types and quantities of affected materials and the degree of apparent damage. The information obtained was used to analyze the extent of the damage and to further determine the scope of the job. Professional testing equipment and the principles of psychrometry was used to formulate a plan to dry and restore, or replace both structural materials and contents. The comprehensive inspection included:

Identifying and evaluating health and safety hazards; Determining the source of water;

Determining the need to protect floor covering materials and contents; Determining the extent of moisture intrusion;

Evaluating and assessing structural materials; Evaluating and assessing inventories and contents; Evaluating the HVAC system;

Documenting preexisting conditions not related to the current loss; Establishing drying goals; and

Determining the scope of the mitigation process to support the total restoration plan.

Based upon the above procedures, a proposal was provided to remove standing water, and to dry the structure to its normal state of equilibrium using desiccant and refrigeration based dehumidification systems and specially designed air moving equipment

(42)

Drying Standards

Structural materials and contents have a certain percentage of moisture for the environment in which they exist. The "normal equilibrium", or moisture content of hygroscopic materials, varies depending upon both relative humidity and temperature in the surrounding air. When these materials are neither gaining nor losing moisture, equilibrium moisture content has been reached.

The dry standard is determined by taking moisture content readings from known dry materials in an undamaged area or similar structure, and using these readings to establish a drying goal. Each floor of the building has been divided into segments where the initial moisture content of the structure was

established. Then, a dry standard was established as a target, and the appropriate environment was created to dry the structure. The drying process was monitored, altering the application of dehumidifiers, air movers, and temperature to create the proper environment to dry the appropriate material. Particular attention was directed toward areas where drying was slow, or non existent

Moisture content of materials is a function of the environment in which they exist. Material exposed to high relative humidity will seek a moisture content equilibrium consistent with the high relative humidity. These materials are regarded as hygroscopic in that they attract moisture from the air.

Conversely, materials exposed to low relative humidity will give up moisture, dry out, and stabilize at a low moisture content equilibrium. The following is a graphic depiction of moisture content as a function of exposure to relative humidity.

The ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc) standard noted above is the design standard for relative humidity in buildings. Accordingly, materials will

equilibrate within the shaded area.

In addition to being exposed to high relative humidity associated with water damage, materials go through a cycle of picking up moisture, and giving up moisture due to normal seasonal changes in temperature and humidity. Thus the design condition is 35% to 60%. The following drawing shows the

(43)

(44)

Environmental Conditions

The damaged structure must be monitored starting with the initial loss assessment and evaluation, and continuing throughout the restoration process. Monitoring procedures may include, but are not

necessarily limited to, temperature and humidity readings, updating progress reports and checking the moisture content of structural materials with a moisture meter. When applicable, monitoring also must include checking equipment operation, work progress and indoor / outdoor environments.

Psychrometry is the science and practice associated with atmospheric air mixtures, their evaluation, control and affect on materials and occupant health and comfort. Drying effectiveness is determined by four factors: temperature, humidity, air movement and time. Managing the relationship between these factors is critical.

Temperature: This refers to the standard or common temperature that is obtained by using a dry-bulb thermometer. Temperature has an effect on the formation of some microorganisms, along with odor and the potential for increased damage to materials on which they grow. Moreover, the health of occupants may be adversely affected when microorganisms proliferate.

Humidity: Temperature has a direct effect on relative humidity. As temperature increases, the moisture holding capacity of air increases, and since the actual moisture in the air remains the same, the relative humidity decreases. Conversely, as temperature decreases, the moisture holding capacity of air decreases, and since4 the actual moisture in the air remains the same, the relative humidity increases. Lower relative humidity promotes evaporation. Higher relative humidity not only slows evaporation, but I can result in condensation if it reaches the saturation point. High relative humidity can result in increased secondary damage. High humidity within structures can cause condensation on colder surfaces, which in turn can promote microorganism growth. This growth may lead to odor and permanent damage. The health of occupants may be adversely affected when microorganism proliferate in closed environments. Grains per pound: Once temperature and relative humidity are known, specific humidity (weight of moisture in the air) can be determined. This is measured in grains of moisture per pound of dry air, which provides a precise measurement of the drying capability of the environment regardless of the

temperature. Accordingly, a target level is established in grains per pound.

Vapor pressure: Once temperature and relative humidity are known, vapor pressure (the force exerted by water vapor on surrounding surfaces) can be determined. Moisture seeks a level of equilibrium with the surrounding environment. The lower the vapor pressure within a room, the faster a structure and its contents will dry.

Air movement: Aggressively moving dry air over a surface of the material to be dried will accelerate the drying process through increased evaporation.

Instruments Used in Water Damage Restoration Procedures

There are several types of instruments that are used to establish moisture content of material, and to monitor temperature and humidity conditions during the job.

In all instances, the instruments are delicate and should be treated with care. When not in use, they should be stored in their carrying case and kept in a temperature-controlled environment. Do not leave instruments in vehicles overnight where they may be subjected to cold temperatures, or during the day where they may be subjected to high temperatures.

These instruments should be calibrated periodically in accordance with the Operation and Maintenance Manuals.

The following is a short summary of the types of instruments and their intended use:

Moisture Content Meters:

These instruments measure the moisture content of a material and there are several types available. Penetrating Resistance Meters - These devices use two pin or nail like electrodes that must penetrate the material to be measured. The electrical resistance between the two pins is determined with a lower resistance indicating that material is wet, and the higher resistance indicating that the material is dry.

There are several different types of probes that can be used with penetrating resistance meters; short pins, insulated pins that they only read at the tips, extended insulated pins, and pins that are attached to a hammer probe.

There are also several different types of meters that provide sensitivity settings for the type of material to be measured, and the temperature of the material.

Non-Penetrating Meters-These meters are designed for wood and other structural materials when penetration may cause damage. They are also very effective during the initial survey or when a quicker measurement is required.

Most non-penetrating meters work by sending an electronic radio wave into the material that is being measured. The instrument then measures the return signal determining the power loss and converting it to a relative moisture content reading.

The primary purpose of this device is to document the conditions that were maintained during

the water damage restoration process. These units should be distributed throughout the areas that are being dried, but should not be mounted in close proximity to dehumidifiers, open doors or windows, or

on outside walls. These areas may provide false readings. Also, mount one unit outside. Thermo hygrometers - This instrument provides a reliable, rapid and highly accurate

measurement of relative humidity and temperature via a direct digital readout. Some of the more expensive units measure wet bulb temperature (dew point), and absolute humidity. The primary use is to monitor environmental conditions that have been specifically created to dry the water damaged structure

and contents.

The instruments and probes are sensitive to shock and extreme conditions, and should be treated

with care. Do not expose the probes directly to high air streams, i.e. the exhaust from the dehumidifiers,

or to chemicals or dust.

Infrared Thermometer- This is a non-contact infrared device that measures the temperature of a

material at the surface by comparing the infrared energy emitted from the material. Temperatures can be

measured from one to forty feet away, and can provide an indication of moisture present. This instrument provides a simple method of surveying materials that are not easily within

reach. Materials that have recently become wet will show a different temperature than materials that are

dry. Also, if insulation behind a wall is wet, it will lose its insulating quality and show a different temperature that a wall with dry insulation.

Environmental Considerations

Environmental conditions should be monitored and recorded on a daily basis. The application of equipment, and the specifics of the drying plan should be altered based upon environmental conditions both inside and outside of the structure that is being dried.

The target relative humidity for drying structures will vary based upon several factors, i.e. location in the country, tightness of the structure, time of year, amount of power to run dehumidifiers, and the ability of the installed HVAC system to operate.

For planning purposes, the ideal initial target for a water damage restoration project is as follows regardless of external conditions:

Control relative humidity within 25% to 40% to accelerate the drying

Keep temperature initially below 70 degrees Fahrenheit to prevent mold and mildew As the drying project proceeds, allow the temperature to increase to accelerate the drying.

The following conditions should be monitored on a daily basis in order to modify the drying plan as require:

External Temperature - temperature outside of the structure to be dried

External Relative Humidity - relative humidity outside of the structure to be dried Internal Temperature - temperature in each area of the structure

Internal Relative Humidity - relative humidity in each area of the structure

Additionally, the NOAA report for local conditions can be downloaded from WWW.NWS.NOAA.GOV for comparison with local measured conditions. This document will also be included in the final report. (Note: sometimes NOAA.GOV doesn’t respond, use WWW.NOAA.COM and this will forward you to the NOAA home page.)
