7. Thoroughly clean the work area to GHA approval and apply two coats of non-slip wax to the terrazzo floor.

8. Remove containment barriers at the living room entrance and the bedroom entrance. Repair any wall damage that may have resulted from the installation/removal of the containment barriers.

Note: this unit is not equipped with central air conditioning, unit is equipped with central heat only

All work is to be performed in accordance with manufactures specifications, industry standards, best work practices and the included mold remediation protocol. All work is to be performed by skilled and qualified workmen in best practices of the trade and in compliance with Building Regulations and or Government Laws, Statues and Ordinances and the included mold remediation protocol Specific Mold Remediation Requirements

1. Air Scrubber: Two 500 CFM air scrubber should be used to provide filtered air during remediation activities. Install the air scrubber’s in the hallway and in the kitchen.

The use of an air scrubber will provide a less hazardous indoor environment for remediation workers, reduce, or eliminate mold spore dispersion to other areas of the residence, and facilitate a successful post-remediation verification.

2. HVAC: Due to the adverse effects of heat stress on workers and productivity, and the possibility of further mold colonization because of increased indoor relative humidity, AirSpec suggests the use of a portable A/C unit during remediation. Attach a high efficiency filter at the return air plenum. High- efficiency filters must be used in an HVAC system during remediation because conventional HVAC filters are typically not effective in filtering particles the size of mold spores. A filter with a minimum efficiency of 50 to 60% or a rating of MERV 8, as determined by Test Standard 52.2 of the American Society of Heating, Refrigerating and Air-Conditioning Engineers, may be appropriate.

3. If an A/C unit is not used, dehumidifiers may be required to keep humidity levels below 65%.

4. Contents: Based on the IICRC S520 Reference Guide for Professional Mold Remediation, the articles of household goods in the work area are in a Condition 3 environment. Condition 3 is an indoor environment contaminated with the presence of actual mold growth and associated spores on the building materials. Actual growth includes growth that is active or dormant, visible, or hidden. The S-520 standard classifies household goods into three categories: porous, semi- porous, and non-porous.

· Porous materials are organic materials that quickly absorb water and provide an excellent food source for molds (e.g., clothing, and other textiles, padded or upholstered items, leather, taxidermy, paper goods and fine art).

· Semi-porous materials are organic materials that absorb water slowly, but still provide a possible food source for molds (e.g., unfinished wood and masonry).

· Non-porous are organic materials which have been altered to not absorb water easily; inorganic or synthetic materials, which do not absorb significant amounts of moisture and/or do not provide a food source for molds (e.g., finished wood, glass, plastic, metal).

Cleaning settled spores from the work area contents can be accomplished by HEPA vacuuming all porous and semi-porous horizontal surfaces and damp wiping all non- porous horizontal surfaces. All linens or textiles should be laundered or dry-cleaned.

5. Containment: Build containment barriers at the living room, on the entrance to the guest bedroom. All containment barriers should, at a minimum, be made of 4 – 6-mil plastic for walls and ceilings and 10-mil plastic for floors. All plastic edges should be secured tightly with painters’ tape and staples, if necessary. Other methods include the use of furring strips, zip-pole, PVC pipe, and two-by-four construction to secure the plastic edges. If there is no direct egress from the containment entrance to the outdoors, place plastic or paper carpet matting in between the containment egress point and the exit door to the residence.

6. Place a MERV 8 filter in the plastic containment barrier, if necessary, to keep the plastic containment barrier from collapsing due to the negative pressure and to prevent unfiltered air from entering the containment.

7. When a decontamination chamber is used, establish an appropriate entry and exit, which is attached to the containment as a transitional space between work areas and unaffected areas of the building. Tack mats can be placed immediately outside the entrance of the decontamination chamber to limit contaminants from being tracked into unaffected areas after removing disposable protective clothing (booties).

8. According to the S520, decontamination chambers are utilized to “provide a transition space between the containment (contaminated area) and surrounding clean areas” (i.e., non-work areas). The objective of decontamination chambers includes “decontaminating the exterior surfaces of plastic bags or sheeting used to contain contaminated materials, remediation tools, and the exterior clothing of personnel when exiting the work area”.

9. Negative pressurization of the containment will capture mold spores that are released during the surface cleaning of bags, tools, and clothing; however, this configuration may not be as effective as a configuration that includes a decontamination chamber. Containments utilizing air scrubbers only (without negative pressurization) should not be expected to capture mold spores during the cleaning of bags, tools, and clothing.

10. Seal all plumbing and gas lines to prevent back-drafting during the operation of the air filtration devices (i.e., AFDs, such as: negative air machines and air scrubbers).

11. Structural Remediation: Remove building materials 12-18 inches past the visible mold colonization. All mold-contaminated building materials removed from the work area must be sealed in plastic bags and then the bags must be cleaned, and HEPA vacuumed prior to removal from the work area. In addition, all protective clothing must be HEPA vacuumed before exiting the containment. All mold contaminated building materials can be disposed of as normal solid construction waste. Due to the nature of this project and the possibility of hidden mold colonization, further removal of building materials may be required. Remediation can begin once the negative air machine and/or air scrubber is in place.

12. Hallway, Kitchen, Water Heater Closet, and Washer/Dryer Alcove: Remove, clean, and save the water heater and save for reuse. Remove all water heater closet wall drywall, water heater closet door frame, washing machine alcove drywall. Remove kitchen sink base cabinets upper and lower and save for later use. Remove all drywall from behind the kitchen cabinets. Inspect the back of the bathroom south wall drywall for hidden water damages and/or mold colonization. If damages are found on the bathroom drywall, notify GHA prior to removing the affected building materials.

13. Inspect the inside of the wall cavities around the remediated areas for any further mold colonization. If additional mold growth is found, remove and/or clean the affected building materials, as necessary.

Mold Remediation Protocol

The purpose of the mold remediation protocol is to provide specific mold remediation steps to control and remove the mold growth present. These steps are based primarily on the Institute of Inspection Cleaning and Restoration Certification (IICRC) IICRC S520 Standard and Reference Guide for Professional Mold Remediation.

The S520 standard is a procedural standard and is based on reliable remediation principles, available scientific and industry literature and information, and practical experience.

The IICRC S520 has categorized the indoor environment into three possible conditions when considering the level of mold spore contamination.

Condition 1: An indoor environment that may have settled spores, mold spore fragments or traces of actual growth whose identity, location, and quantity, are reflective of a normal mold spore ecology for a similar indoor environment.

Condition 2: An indoor environment which is primarily contaminated with settled spores that were dispersed directly or indirectly from a condition 3 area, and which may have traces of actual growth.

Condition 3: An indoor environment contaminated with the presence of actual mold growth and associated spores. Actual growth includes growth that is active or dormant, visible, or hidden.

Based on the laboratory analysis of the spore trap air sampling collected, the suspect mold colonization has been confirmed as Condition 3 mold growth.

The entire residence is considered to be a Condition 3 Environment. Remediation and clean-up of the mold contaminated building materials, contents, and furnishings is necessary. It is also necessary to install a negative air machine for proper ventilation during the remediation and follow specific mold removal and cleanup guidelines based on the IICRC S-520 Standard

Microbial Decontamination, Drying, and Clearance Testing

The Scope of Work that addresses microbiological decontamination includes, but is not limited to the following activities in the residence:

Work Process Summary:

1. Set up negative air filtration. (Entire residence will be placed under negative pressure.)

2. Remediate the unit according to the IICRC S520 Standard for a Condition 3 Environment.

3. Begin the cleaning process in the room farthest from the negative air machine and then clean the residence in the direction towards the machine.

4. Conduct a post-remediation inspection.

Specific Mold Remediation Requirements:

1. Containment: No containment barriers are required; the entire residence is considered the work area.

2. Negative Air: One negative air machine should be used to provide ventilation during remediation. Install a negative air machine in the living room and exhaust through the window. A piece of plywood or rigid foam board insulation can be used to support the exhaust duct and provide a tight seal.

Open a window in the bedroom to allow for make-up air flow. The idea is to create an air current through as much of the work area as possible.

The use of a negative air machine will provide a healthy indoor environment for remediation workers, protect mold spore’s dispersion to other areas of the residence, and will also facilitate a successful post-remediation inspection. Negative pressure must be maintained throughout the duration of the remediation. The negative air machine should be converted to air scrubber mode during non-work hours to maintain the security of the residence. The negative air machine should continue to operate for two days after the remediation is completed.

3. HVAC: The unit is not equipped with a method to remove elevated humidity; dehumidifiers may also be required to keep humidity between 30% and 50%

A qualified licensed HVAC contractor is to clean the air handler, ductwork, diffusers, registers prior to post remediation testing. Invoice from the HVAC Contractor performing this work is to be included with the close out documents/invoice for this project.

4. IICRC S-520 Standard and Reference Guide for Professional Mold Remediation:

The S-520 standard classifies household goods into three categories: porous, semi-porous, and non-porous.

Porous materials are organic materials that quickly absorb water and provide an excellent food source for molds (e.g., clothing and other textiles, padded or upholstered items, leather, taxidermy, paper goods and fine art).

Semi-porous materials are organic materials that absorb water slowly, but, still provide a possible food source for molds (e.g., unfinished wood and masonry).

Non-porous are organic materials which have been altered to not absorb water easily; inorganic or synthetic materials, which do not absorb significant amounts of moisture and/or do not provide a food source for molds (e.g., finished wood, glass, plastic, metal).

The remediation of Condition 3 household contents can be summarized as:

Type: Porous, Semi-Porous, Non-Porous Disposition: Restore by cleaning Cleaning settled spores is accomplished by HEPA vacuuming all porous and semi-porous horizontal surfaces and damp wiping all non-porous horizontal surfaces. All linens or textiles should be laundered or dry-cleaned.

NOTE: Porous and semi-porous contents that are severely mold damaged (Condition 3) should be discarded.

All irreplaceable items can be cleaned at the risk of the owner.

5. Remediation: Begin the remediation cleaning process in the room farthest from the negative air machine and then clean the residence in the direction towards the machine.

Any mold-contaminated contents, furnishings, or building materials removed from the work area can be transported directly to a trash receptacle located outside of the unit. All mold contaminated building materials can be disposed of as normal solid construction waste. Remediation can begin once the negative air machine is in place. Remove building materials 12-18 inches past the visible mold colonization.

All Contents, Clothing, Furnishings, & Textiles: Micro-clean (HEPA vacuum and damp wipe with an anti-microbial solution) all salvageable contents in the work area; all salvageable contents should be cleaned by a method based on material composition, manufacturer instructions, and in accordance with the IICRCS-520 Standard for Condition 3 household goods. All cleaned salvageable contest should be store in a climate-controlled storage pod/facility.

All Other Surfaces: Micro-clean all walls, fixtures, appliances, counters, cabinets, doors, window casings, ceilings, etc. inside the residence. Clean any carpeting using hot water extraction methods. Use a minimal amount of water in the cleaning process. (It may be necessary to scrape the ceilings and/or walls prior to micro-cleaning – this will depend on the severity of the mold growth at the time the remediation is being conducted.)

Provide sufficient drying time for all surfaces that were cleaned.

It is expected that the remediation contractor has experience in microbial remediation and therefore will be held to a professional standard with regard to complete removal of contaminated materials. GHA should be contacted if microbial growth outside the scope of this report is found. Any further remediation should be accomplished in accordance with NYC Guidelines, EPA recommendations, or the IICRC S520 Standard. If extensive additional remediation is required, the contractor should contact GHA and provide a description.

Occupancy During Remediation The residence should not be occupied by anyone other than professional mold remediators during remediation activities.

Preliminary Health & Safety Measures The disturbance or dislocation of microbially-contaminated material and the disinfection of microbially contaminated facilities may cause molds, spores, or other biological agents to be released into the building’s atmosphere, thereby creating a potential hazard to workmen and building occupants. Apprise all workers, supervisory personnel, subcontractors and consultants who will be at the job site of the seriousness of the hazard and of proper work procedures that must be followed. It is anticipated that significant amounts of toxigenic fungi can be released by this work activity if proper procedures are not followed. All cleaning and decontamination activities should follow the general guidelines listed below.

1. Protection of the safety and health of remediation workers and building occupants is of paramount importance in mold remediation projects. Each employer must comply with safety and health regulations applicable to businesses that perform this work. Generally, these include, but are not limited to:

i. Use protective coveralls whenever entering a contaminated area.

j. Repair or replace any damaged protective equipment.

k. Dispose of contaminated protective clothing prior to exiting a work area.

l. Wear latex, chemically resistant, or vinyl surgical gloves while inside containment areas.

m. Wear a second pair of work gloves over the surgical gloves to protect against personal injury.

n. In the event a glove is damaged, discard the glove, wash hands with soap and water, and inspect hands for injury.

o. All workers involved in project set up activities shall wear appropriate eye protection and safety shoes.

p. All workers actively involved in removal of moldy building materials, surface cleaning or decontamination activities should wear Impervious gloves when skin/hand contact with active mold growth is likely and full-body protective (TYVEK or similar) disposable clothing at all times.

q. Workers should wear N-95 respirators in the contaminated areas and full-facepiece respirators equipped with P-100 cartridges during remediation activities. All workers involved in applying chlorine-based biocides or cleaning solutions shall wear full facepiece respirators equipped with P-100 pre-filters/cartridges and cartridges approved for use with chlorine or acid gases.

r. Before exiting from the containment, all workers will HEPA vacuum their suits in the decontamination area. Respiratory protection must be disinfected according to manufacturer recommendations.

Cleaning and Decontamination Procedures and Requirements

The following is a general outline of the procedures that should be used to decontaminate building surfaces and addresses the general requirements for a safe and effective cleaning and decontamination project.

1. Preliminary Activities

a. Prior to initiating any micro-cleaning activities, A/C supply and return air vents that will be inside the containment must be sealed off.

b. Attach ground fault circuit interrupters (GFCI’s) to any electrical equipment that will be used in the project.

2. Contents Cleaning – All indicated contents should be cleaned or discarded in accordance with the IICRC S-520 standard.

a. All contents in the containment area should be cleaned by a method based on material composition and manufacturer instructions. After cleaning, all items that were removed from the containment area should be stored in the non-work area or in a remote storage location.

b. Contents should be separated into one of three categories – Non-porous, semi-porous, and porous.

c. All porous and semi-porous contents that were directly water damaged and present active mold growth should be discarded.

d. Non-porous items, in most circumstances, are restorable.

e. Semi-porous and porous items are restorable if only general air contamination is present and/or the mold contamination is only settled spores.

f. Do not dispose of any items without the consent of the financially obligated party and homeowner.

3. Create regulated work area and arrange for containment of work area.

a. Install the Air Filtration Device. Remediation can begin once the AFD is installed. Maintain appropriate air pressure differential control to remove any contaminants that could be released during the removal and cleaning operations and to prevent cross contamination. Use an AFD to exhaust the work area continuously during the project. The AFD should be positioned at the furthest point and/or downwind from the entrance. A sufficient number of AFD’s must be utilized in order to maintain 4-12 air changes per hour or an air pressure differential of -0.02 water gauge in the work area. Visually confirm that a negative air pressure is always present. If negative pressure is lost, stop all remediation activities, and repair the leak.

b. Install necessary environmental control equipment (portable A/C, dehumidifiers) in order to maintain a safe working atmosphere.

4. Work Area Gross Contamination Remediation.

a. All identified impacted materials should be treated and/or removed. The removal of contaminated material should extend two feet past the visible mold contamination.

b. Cut out the impacted building materials in a controlled manner in order to reduce the level of dust and spread of mold. Two-man teams should be employed and HEPA vacuums should be used to control dust.

c. Spraying or misting materials prior to removal is not recommended.

c. Hidden Mold – During the remediation process-hidden mold may be discovered. Small areas of mold may be remediated. Large areas greater than three square feet should be reported to GHA and proper procedures for removal should be agreed upon.

d. The use of encapsulants, sealants, ozone, and ultraviolet light as a substitute for source removal and detailed cleaning is generally not recommended.

e. The exposed structural members, studs, sill plates, floors, and beams should be HEPA vacuumed, treated with the cleaning solution, and HEPA vacuumed again. Heavily impacted structural members that cannot be cleaned should be considered for replacement or sanded and HEPA vacuumed. All other remaining materials should get the HEPA-clean-HEPA treatment.

f. All discarded building materials and personal effects will be gooseneck sealed in plastic bags. All bags leaving the containment must be HEPA vacuumed. There are no specific requirements for the disposal of moldy materials.

5. Decontaminate the containment area after all mold amplification is removed.

a. Thoroughly HEPA vacuum all surfaces within the containment area.

b. Prepare the cleaning solution. MIST the surfaces of all areas that have been HEPA vacuumed and wipe clean.

c. All horizontal and vertical surfaces will then be HEPA-vacuumed again.

d. Remove all waste material from the work area in 6 mil plastic bags and dispose of as normal solid waste.

e. The negative air machines or air scrubbers should be left on for two days after the mold is removed and prior to the post-remediation inspection.

6. Post-Remediation Inspection

a. Post-remediation clearance of the work area can be conducted by request of the interested parties. Clearance testing will be based on accepted microbiological post-remediation testing (clearance) protocols. Testing Contractor will be looking for an environment void of visual microbial growth and moisture. Also, one that does not indicate unusual microbiological conditions with respect to species present and comparison with reference samples.

b. Air scrubbers or negative air should continue to operate for 48 hours after the remediation is completed. Next, the air scrubbers or negative air should be shut down and the post-remediation inspection should occur 24 hours later. This amounts to a three-day period between the time the remediation is completed, and the post remediation inspection occurs. This practice will allow a sufficient number of air changes to help ensure airborne mold spores have been removed from the containment area.

In order to pass a Post-Remediation Inspection, there must be no visible mold on any remaining remediated building materials. If the visual inspection is satisfactory, air sampling will be conducted. All air samples must have a total mold spore count within the ranges specified on the following table. These levels are typical outdoor mold spore levels for the State of Florida compiled by Environmental Microbiology Laboratory Inc. (2008).
