OBSERVATIONS & FINDINGS

There is a heat exchanger located in the southwest corner of the boiler room that is leaking and is the source of moisture that has allowed mold to develop in this part of the boiler room and the adjacent locations. The leak from this heat exchanger cannot be fixed without shutting down the heating/cooling system for the building. This is being addressed as part of the boiler replacement project, which will include the installation of temporary boilers to allow the building to remain occupied while the project is completed.

Water damage was evaluated in the boiler room, and any adjacent locations possibly affected by the water leak from the heat exchanger. Some amount of fungal growth (mold) contamination was determined to exist associated with building materials (wallboard) at four (4) of the five (5) suspect locations.

1. Boiler Room (119) - Wallboard in contact with water from the heat exchanger has allowed mold to develop at the base of the walls in the southwest corner. Mold exists (mainly behind vinyl base) at the base of the south and west walls in the boiler room as a result of the heat exchanger leak. Unrelated to the heat exchanger leak, a small amount of historic water damage/mold was determined to exist at the base of the wall in the northeast corner of the boiler room in the vicinity of the hot water heater. Currently, there was no moisture identified at this location and the minimal damage that exists is believed to be historic in nature.

Mold was sampled at the base of the west wall in the boiler room and determined to be Penicillium/Aspergillus, and Ulocladium species. There is approximately 15 square feet of mold behind the vinyl base at this location with an unknown amount inside of the wall cavity. On the east wall, behind the water heater there is <1 square foot of mold also at the base of the wall behind the vinyl base.

Remediation will require the removal of wallboard to a height of 4 feet from the entire south and west walls, and approximately 10 linear feet from the northeast corner. Approximately 200 square feet of wallboard will need to be removed in the boiler room to address the current mold concerns. It is recommended that, as part of the project, the bottom 4 feet of wallboard be removed from all of the boiler room walls and replaced with materials more resistant to water damage and mold such as glass fiber faced Gypsum Wall Board, or equivalent. Consult with Building Science Corporation (BSC) with regard to wallboard replacement material for the boiler room.

2. Mechanical (118) – Water damaged wallboard and small amounts of mold were determined to exist at the base of the north wall that is shared with the boiler room. Again, the mold identified was only at the base of the wall and behind the vinyl base, and is the result of the heat exchanger leak.

There is approximately 5 square feet of mold behind the baseboard at this location with an unknown amount inside of the wall cavity. Remediation will require the removal of wallboard to a height of 4 feet from the north mechanical room wall, adjacent to the boiler room, from the doorway to the northwest corner and a small section of the west wall. Approximately 80 square feet of wallboard will need to be removed from this location to address the current mold concerns.

3. CCMS (112) – Mold was found to exist in the northeast corner of the CCMS room and at this location the mold was visible to a height of about 2 feet up the wall behind a storage cabinet. Unlike in the boiler and mechanical rooms, where it appears that residual heat in the area has likely dried moisture from the wallboard minimizing mold growth on the exposed wall surface, conditions in the CCMS have allowed mold to develop on the exposed surface and not just behind the vinyl base. There is over 10 square feet of mold contamination on finished surfaces at this location.

Mold was sampled on the east wall in the CCMS room and determined to be Stachybotrys species. Remediation will require the removal of wallboard to a height of 4 feet from the east, north and a small section of the west walls.

Approximately 80 square feet of wallboard will need to be removed from the CCMS room. Sealing the return air vent and minimizing access into the CCMS room is recommended to help minimize any potential for exposure should the exposed mold be inadvertently disturbed prior to its removal.

4. Fiber Optics Electronics (111) – The northeast corner of Room 111, that is adjacent to the areas of concern, was evaluated by removing the vinyl base, testing for moisture, and visually inspecting for signs of water damage and mold.

Findings in this area were unremarkable as signs of water damage/mold in this area were not identified. Remediation at this location is not necessary.

5. Stair No. 1 (102) – Moisture was determined to exist in the south wall of the stairwell to a height of about 2 feet above the bottom level of the stairs. Mold was observed behind the vinyl base at this same location, which is adjacent to both the boiler room and the CCMS water damaged locations. Mold was not observed on the finished walls above the vinyl base.

Mold was sampled from behind the base on the south wall of Stair No. 1 and determined to be Penecillium/Aspergillus and Stachybotrys species.

Remediation will be required to remove the wallboard to a height of 4 feet from the south and east walls at this location. Approximately 56 square feet of wallboard will need to be removed from this location. The thickness and number of layers of wallboard that will need to be removed will need to be field verified.

CONCLUSIONS & DISCUSSION

Mold remediation will need to occur in the identified locations and should occur in conjunction with the current boiler replacement project. Based upon the visual observations, evaluation, and review of all available data, GA recommends that the following remediation steps be conducted. The goal of remediation is to clean or remove the materials affected by fungal growth in a way that prevents the emission of fungi and dust contaminated with fungi from leaving the work area and entering other areas of the building.

Project Sequence -

As with any water damage/fungal growth event, the source of the moisture needs to be identified and corrected prior to or in conjunction with any remediation, in order to minimize the possibility of the fungal growth problem reoccurring. As work in the boiler room will be necessary in order to address the source of the water that has caused the noted damage, sequencing the remediation with the construction work will be necessary.

It is recommended that the following actions be completed in the boiler room in order to help ensure a successful project.

1. Walls inside of the boiler room that are contaminated with mold should be protected to ensure that the mold is not disturbed by work/demolition activities inside of the boiler room. This can be accomplished by installing plywood along the bottom of the west and south walls of the boiler room at any location that could possibly be damaged. The plywood should be held up off the floor so that it does not wick moisture.

2. Complete the cutover and install for the temporary boilers. Ensure that work activities, including temporary plumbing and electrical work, do not disturb any of the identified mold contaminated wall locations.

3. Complete demolition work of equipment from inside of the boiler room. Again, ensure that work activities do not disturb identified mold contaminated locations.

4. Remediate the mold/water-damaged materials from the boiler room and adjacent locations. Complete necessary inspections, testing, and rebuild. It is estimated that this work activity will require approximately 2 weeks to complete.

5. Continue with boiler replacement project work.

Necessary water damage and mold remediation activities based upon findings to date:

• The attached interior remediation procedures shall be utilized for the removal of all interior wallboard that is water damaged and any associated insulation in the Boiler Room and adjacent locations.

The potential health hazard for building occupants and maintenance personnel to the fungal growth material that has been identified is currently minimal. Addressing the materials identified as recommended will help ensure that the risk to personnel and the facility are appropriately managed.

REMEDIATION COST ESTIMATE

Estimated costs for this remediation work to be conducted at this location:

$ 11,250.

Estimated costs for remediation oversight and project clearance:

$ 7,400.

REMEDIATION RECOMMENDATIONS

Appendix A – Boiler Room and Adjacent Locations

Interior Remediation Procedures

These recommendations are designed to assist in the interior evaluation, removal and cleanup of materials contaminated or likely contaminated with visible fungal growth and surfaces contaminated with fungal contaminated dust. These remediation procedures should be completed in the order provided and documentation that each step was properly completed should be maintained. All remediation and clearance work activities shall be completed in accordance with the FAA’s ATO IAQ Program Implementation Requirements – Chapter 5.

1. Identify and correct all potential sources of moisture intrusion – remove leaking heat exchanger.

2. Remediation workers shall be trained in the handling of hazardous waste materials and the health effects of fungal growth.

3. Proper protection for remediation workers should at least consist of, disposable protective coveralls, eye protection, gloves, and a properly fitted NIOSH-approved respirator with P-100 HEPA filters.

4. All contents within the designated work areas (Boiler Room and adjacent contained locations) shall be inspected, cleaned with a high efficiency particulate air (HEPA) vacuum and/or by wet wiping if necessary, and properly stored.

5. Isolate the work areas and create a directional airflow from other areas of the building into the work area. Turn the work area into a negative pressure enclosure by constructing isolation barriers and exhausting air from the work area to the outside through negative air machines equipped with HEPA filtration. Ensure that any gaps between the work area and the other areas of the base building have been sealed. This is to ensure that fungal spores and dust from the construction does not migrate to other areas of the building during the cleanup activity.

6. Ensure that any supply and return air grills located in the work area are isolated from the work area.

7. Remove the materials that are contaminated or likely contaminated with fungal growth at each location where water damage is determined to exist.

7.1. Remove the interior wallboard walls to a height of 4 feet at locations as depicted in the attached location sketch. This will include drywall and any existing wall insulation.

7.2. In all circumstances, removal of drywall and insulation shall be at least 2 feet beyond where visible fungal growth is observed.

7.3. Dust suppression methods, such as misting (not soaking) surfaces prior to remediation, are recommended.

8. Thoroughly clean all surfaces that remain within the enclosed area. Following the removal of all visible fungal growth with a HEPA vacuum, all surfaces shall be cleaned with a damp cloth, hard brush and a detergent solution.

9. Materials to be removed shall be taken from the work area sealed in a minimum of 6-mil plastic.

10. As the removal of fungal growth from semi-porous surfaces is a difficult task, coat any semi-porous surfaces (unfinished drywall in wall cavities) that remain within the work area with a fungal protective coating.

11. Upon completion, all areas within the work area should be dry and visibly free of fungal contamination, dust, and debris.

12. A visual inspection of the work area coupled with air sampling will be used to determine if the fungal growth remediation has been successful prior to the start of re-construction activities. Gandalf Associates, Inc. can conduct this interim inspection once all of the required remediation work has been completed, and the contained area has not been disturbed for at least 24 hours.

13. Following any remediation activity, visual inspections should be conducted at appropriate intervals to ensure that completed corrective actions have eliminated the cause of the fungal growth.

In addition to the above procedures, documentation (i.e. checklists) should be maintained on a daily basis for the following:

Engineering controls such as critical barriers and containment, are being properly maintained;

Safety and security of the site and site conditions are verified;

Any potential fire and/or health hazards are properly managed;

Proper fungal growth remediation procedures are being followed to ensure that materials are being removed in a way that prevents the emission of fungi and dust contaminated with fungi from leaving the work area, and that workers performing the remediation activities use appropriate personal protective equipment.

Exposure controls

Appropriate engineering controls

Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection.

The basic types of engineering controls are:

Process controls which involve changing the way a job activity or process is done to reduce the risk.

Personal protection

Eye and face protection Chemical goggles.

Full face shield may be required for supplementary but never for primary protection of eyes.

Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants.

Skin protection See Hand protection below

Hands/feet protection

Wear chemical protective gloves, e.g. PVC.

Wear safety footwear or safety gumboots, e.g. Rubber When handling corrosive liquids, wear trousers or overalls outside of boots, to avoid spills entering boots.

NOTE:

The material may produce skin sensitisation in predisposed individuals. Care must be taken, when removing gloves and other protective equipment, to avoid all possible skin contact.

Contaminated leather items, such as shoes, belts and watch-bands should be removed and destroyed.

The selection of suitable gloves does not only depend on the material, but also on further marks of quality which vary from manufacturer to manufacturer. Where the chemical is a preparation of several substances, the resistance of the glove material can not be calculated in advance and has therefore to be checked prior to the application.

The exact break through time for substances has to be obtained from the manufacturer of the protective gloves and has to be observed when making a final choice.

Body protection See Other protection below

Other protection Overalls.

P.V.C apron.

Barrier cream.

Respiratory protection

Type A Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent)

Cartridge respirators should never be used for emergency ingress or in areas of unknown vapour concentrations or oxygen content.

The wearer must be warned to leave the contaminated area immediately on detecting any odours through the respirator. The odour may indicate that the mask is not functioning properly, that the vapour concentration is too high, or that the mask is not properly fitted. Because of these limitations, only restricted use of cartridge respirators is considered appropriate.

Cartridge performance is affected by humidity. Cartridges should be changed after 2 hr of continuous use unless it is determined that the humidity is less than 75%, in which case, cartridges can be used for 4 hr. Used cartridges should be discarded daily, regardless of the length of time used

SECTION 11 Toxicological information

Information on toxicological effects

Inhaled

The material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage.

Not normally a hazard due to non-volatile nature of product The material has NOT been classified by EC Directives or other classification systems as 'harmful by inhalation'. This is because of the lack of corroborating animal or human evidence.

Ingestion The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion.

The material has NOT been classified by EC Directives or other classification systems as 'harmful by ingestion'. This is because of the lack of corroborating animal or human evidence.

Skin Contact

The material can produce chemical burns following direct contact with the skin.

Skin contact is not thought to have harmful health effects (as classified under EC Directives); the material may still produce health damage following entry through wounds, lesions or abrasions.

Open cuts, abraded or irritated skin should not be exposed to this material Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.

Eye The material can produce chemical burns to the eye following direct contact. Vapours or mists may be extremely irritating.

If applied to the eyes, this material causes severe eye damage.

Chronic

Repeated or prolonged exposure to corrosives may result in the erosion of teeth, inflammatory and ulcerative changes in the mouth and necrosis (rarely) of the jaw. Bronchial irritation, with cough, and frequent attacks of bronchial pneumonia may ensue.

Long-term exposure to respiratory irritants may result in airways disease, involving difficulty breathing and related whole-body problems.

Skin contact with the material is more likely to cause a sensitisation reaction in some persons compared to the general population.

Substance accumulation, in the human body, may occur and may cause some concern following repeated or long-term occupational exposure.

EDTA TETRASODIUM SALT

* Sigma Aldrich - for the dihydrate For ethylendiaminetetraacetic acid (EDTA) and its salts:

EDTA is a strong organic acid, with a high affinity for alkaline-earth ions (for example, calcium and magnesium) and heavy-metal ions (such as lad and mercury), resulting in highly stable chelate complexes. The ability of EDTA to complex is used commercially to either promote or inhibit chemical reactions, depending on application.

EDTA and its salts are expected to be absorbed by the lungs and the gastrointestinal tract; absorption through skin is unlikely. They cause mild skin irritation, and severe eye irritation.

SODIUM CARBONATE

For sodium carbonate:

Sodium carbonate has little potential for skin irritation, but is irritating to the eyes. Due to its alkaline properties, irritation of the airways is also possible.

There is no data available for animal studies regarding the repeated dose toxicity of sodium carbonate by any route.

There is no evidence that sodium carbonate causes whole-body effects under normal handling and use. Sodium carbonate does not reach the foetus or the reproductive organs, which shows that there is no risk for developmental or reproductive toxicity.

The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.

ALCOHOLS C12-14 SECONDARY ETHOXYLATED

Polyethers (such as ethoxylated surfactants and polyethylene glycols) are highly susceptible to being oxidized in the air. They then form complex mixtures of oxidation products.

Animal testing reveals that whole the pure, non-oxidised surfactant is non-sensitizing, many of the oxidation products are sensitisers. The oxidization products also cause irritation.

Humans have regular contact with alcohol ethoxylates through a variety of industrial and consumer products such as soaps, detergents and other cleaning products. Exposure to these chemicals can occur through swallowing, inhalation, or contact with the skin or eyes. Studies of acute toxicity show that relatively high volumes would have to occur to produce any toxic response.

Both laboratory and animal testing has shown that there is no evidence for alcohol ethoxylates (AEs) causing genetic damage, mutations or cancer. No adverse reproductive or developmental effects were observed.

Tri-ethylene glycol ethers undergo enzymatic oxidation to toxic alkoxy acids. They may irritate the skin and the eyes. At high oral doses, they may cause depressed reflexes, flaccid muscle tone, breathing difficulty and coma.

CARBONATE

Asthma-like symptoms may continue for months or even years after exposure to the material ends. This may be due to a non-allergic condition known as reactive airways dysfunction syndrome (RADS) which can occur after exposure to high levels of highly irritating compound. Main criteria for diagnosing RADS include the absence of previous airways disease in a non-atopic individual, with sudden onset of persistent asthma-like symptoms within minutes to hours of a documented exposure to the irritant.

The following information refers to contact allergens as a group and may not be specific to this product.

Contact allergies quickly manifest themselves as contact eczema, more rarely as urticaria or Quincke's oedema. The pathogenesis of contact eczema involves a cell-mediated (T lymphocytes) immune reaction of the delayed type. Other allergic skin reactions, e.g. contact urticaria, involve antibody-mediated immune reactions.

CHLORIDE

The material may cause severe skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin. Repeated exposures may produce severe ulceration.

Alkyldimethylbenzylammonium chlorides are in the list of dangerous substances of council directive, classified as 'harmful in contact with skin and on ingestion', and 'corrosive and very toxic to aquatic organisms'. It can cause dose dependent skin and eye irritation with possible deterioration of vision, possible sensitisation in those with pre-existing eczema. It does not cause cancer, genetic defect, foetal or developmental abnormality.
