25217.00 – Halifax Health 200 Wing Remediation Guidance Document Halifax Health Child and Adolescent BHU – Daytona Beach, FL December 5, 2025

These remediation guidelines are based specifically upon the onsite visit and photo documentation collected by EMS on November 3, 2025, and are not intended to take into account the changing conditions within the subject property after this date or conditions in other potentially impacted areas of the facility.

EMS has no firsthand knowledge as to the extent or completeness of any prior building repairs, moisture intrusion, remediation, and/or clean-up efforts that may have taken place at the property or within these target spaces prior to this date. These guidelines are also not intended to address asbestos, lead, or other environmental, health, or safety hazards.

Prior to the implementation of these guidelines, sources of moisture intrusion and/or microbial sources are to be addressed and corrected to prevent further impacts, building material degradation, and microbial amplification. Corrections and repairs are to be made by the appropriate Florida-licensed trade professional(s).

These specifications apply to all individually phased containments. Project phasing for the execution and completion of this project should be defined and agreed upon by the facility, the remediation company, and the consultant. All containment and critical barrier installations should be reviewed by the consultant prior to the commencement of remediation work.

Containment is understood to be the areas where remediation work will be performed, and air clearance activities will take place. The containment is to remain in place and under negative pressure until acceptable post-remediation air verification sampling results have been achieved.

The contained spaces are to remain vacated by the general public, employees, patients, and any personnel who are non-essential to the remediation activities until all remediation activities have been completed and verified through final air verification sampling.

EMS recommends the following products be used, as applicable, for the execution of this remediation guidance:

Bioesque Botanical Disinfectant - to clean and disinfect all surfaces. No rinse is required on food-contact surfaces. It kills mold, viruses, and bacteria (including tuberculosis). EPA-approved to be used with ULV foggers and electrostatic sprayers. EPA-approved to be used in HVAC systems, including ductwork.

Bioesque Mold Resistant Coating - to encapsulate. This product has four EPA-approved ingredients added to help prevent future mold growth and is Lubrizol certified.

Bioesque Protect 90 - to fog. It is safe to use on hard and soft surfaces to protect from mold, fungus, algae, bacteria, and odor-causing bacteria growth. EPA-approved to be used with ULV foggers and electrostatic sprayers as a final step to remediation before clearance testing. EPA-approved to be used in HVAC systems.

Applicable Standards

All remediation work shall be conducted in accordance with applicable IICRC S500, Occupational Safety and Health Administration (OSHA), National Institute of Occupational Safety and Health (NIOSH), and Environmental Protection Agency (EPA) requirements, as well as any applicable state and local requirements.

All remediation activities shall comply with local, state, and federal guidelines associated with the demolition and remediation of moisture-compromised building materials. This includes, but is not limited to, the following:

• City of Daytona Beach

• Volusia County

• State of Florida

• Environmental Protection Agency (EPA)

• Occupational Health and Safety Administration (OSHA)

The Remediation Company (RC) shall follow regulations established by OSHA or recommendations by the National Institute of Occupational Safety and Health (NIOSH), the EPA, and state agencies for the protection of their employees during all remediation work. Personal protective equipment (PPE) is to conform to applicable standards set forth by both NIOSH and the American National Standards Institute (ANSI). The supply of PPE equipment and associated training of employees in the use, maintenance and limitations of the equipment is the sole responsibility of the remediation contractor.

If any requirements, notifications, and/or regulations overlap among or between the above references, the most stringent provisions shall apply.

Containment(s) and Critical Barriers

Based upon the data collected during the on-site assessment, it is recommended that the entirety of the 200 wing be placed under a negative pressure containment. Additionally, it is recommended that each patient room and the therapy room be placed under secondary containments that isolate these spaces from the rest of the wing.

Containments are to remain under negative pressure throughout the duration of the project until post-remediation verification testing confirms that the spaces are safe, containments can be removed, and the spaces can be released for continued occupancy.

Containment

• Containment walls are to be constructed of fire-retardant 6 mil. polyethylene sheeting or edge guard hard panels.

• Using fire-retardant 6 mil. polyethylene sheeting, erect a floor-to-ceiling containment anteroom.

Due to the special security considerations specific to this facility, the anteroom may be located immediately inside the double door entry to the wing from the main corridor.

• A zip door is to be installed at the entry to the wing from the anteroom. Additionally, a zip door is to be installed at the entry to each patient room and therapy room.

• All containment and anteroom doors and barriers, as applicable, are to be sealed tightly at the ceiling and floor.

The RC shall use fire-retardant 6 mil. polyethylene sheeting to install critical barriers to isolate the entirety of each target space from possible contamination sources. These include:

Halifax Health Child and Adolescent BHU – Daytona Beach, FL

• Adjacent spaces

• HVAC supplies/returns

• Pass-through wall vents

• Outlets and switches

• Breaches in the exterior wall envelope

• Open drains

• Above-ceiling spaces

• Exterior windows

Zip doors, edge guard panels, containment barriers, and critical barriers should be inspected regularly to ensure integrity is maintained.

Foot Traffic

The RC shall restrict traffic entering and exiting the contained area to only the necessary remediation personnel during all remediation activities and will ensure that all travel paths for materials and waste debris remain clear for the duration of the project.

The RC shall utilize sticky walk-off mats inside the entry to the containment from the anteroom to control footwear dust and dirt tracking. Walk-off mats are to be inspected regularly for dirt loading and changed as they become laden with dirt. Mat edges are to be secured to the floor to prevent a tripping hazard.

• New shoe coverings are to be donned upon each entry into the main containment and are to be removed and discarded upon each exit.

Negative Pressure Specifications

HEPA-filtered negative air/scrubber machines equipped with GFCI overcurrent protection shall be used to provide negative pressure to the contained spaces. The effluent air shall be exhausted to the exterior of the building.

• A minimum of -.02 inches of water column pressure differential relative to outside pressure is to be maintained within the negative pressure containment(s).

• A differential pressure recorder with data-logging capability is recommended. If unavailable, a number of negative air machines are to be used that ensure a minimum of 6 air exchanges per hour by calculation. Visual verification that all scrubbers are operational is to be documented a minimum of three (3) times per eight (8)-hour shift and spaced at least two (2) hours apart.

• During demolition or dust-generating activities inside containment(s), HEPA filters and pre-filters should be changed a minimum of twice daily.

• In areas where non-demolition or dust-generating activities are taking place, HEPA filters and pre-filters are to be changed daily.

• Negative air/scrubber machines are to be cleaned by vacuuming and antimicrobial wet wiping before new filter installation.

HVAC System

The HVAC system servicing the unit is to undergo cleaning and sanitization. This should include spiral fans, drip pans, interior air handling units, coils, gasketing, and supply/return grills. Additionally, any interior-lined ducts or duct board is to be encapsulated. Once complete, the system(s) should be isolated from areas undergoing remediation until remediation has been completed.

This work shall be completed as per the National Air Duct Cleaners Association (NADCA) cleaning standard ACR 2013 - Assessment, Cleaning, and Restoration 2013.

Halifax Health Child and Adolescent BHU – Daytona Beach, FL

Soft Goods

All soft goods materials, such as clothing and textile furniture that lend themselves to professional cleaning, should be bagged and removed from the contained areas for cleaning. Bags are to be HEPA vacuumed and antimicrobial wet-wiped prior to removal from containment.

Multi-layer textiles that do not lend themselves to cleaning, such as mattresses, are to be completely wrapped in poly, the poly secured with duct tape and removed from containment for disposal. Poly is to be HEPA vacuumed and antimicrobial wet-wiped prior to removal from containment.

Hard Goods

All non-porous hard goods, fixturing, and furniture shall be HEPA vacuumed and wet-wiped, using Bioesque or an equivalent EPA-approved antimicrobial, and re-vacuumed. After cleaning, mobile hard goods are to be completely wrapped in poly, the poly secured with duct tape, and removed from containment. These items should not be returned to the wing until post-remediation air verification sampling has been performed and acceptable air quality results have been achieved.

Wet wipes are to be changed frequently.

All used wipes are to be bagged and disposed of as microbial contaminated debris, or, if applicable, bagged and sent for professional cleaning.

Demolition, Cleaning, and Sanitization

Patient Rooms and Therapy Room

• As indicated on the attached impact map, chalk and score the walls along the flood cut lines in preparation for drywall removal.

• Make clean cuts along the detail lines to remove the impacted drywall walls along with any associated impacted insulative materials, and bag them for disposal.

• With the wall cavities open, any source(s) of moisture are to be identified and corrected, and the wall cavity is to be inspected for any additionally impacted materials that may need to be removed.

• Perform structural drying as required and verify that all materials are dry prior to proceeding.

• Impacted structural components such as studding and sill plates are to be evaluated for deterioration and repair or replacement.

• All exposed structural members are to be cleaned, sanitized, and encapsulated using a Lubrizol-certified anti-microbial encapsulant.

• Gross cleaning is to be accomplished through the use of wire brushes, scrapers, nylon brushes, rags, etc. Upon completion of gross cleaning, structural members are to be HEPA vacuumed, followed by wet wiping using Bioesque antimicrobial, and re-vacuumed.

• Build back as required. At the conclusion of build-back, all new drywall is to be encapsulated using Lubrizol-certified Bioesque Mold Resistant Coating to prevent future microbial amplification.

• Foggers utilizing Bioesque Botanical Disinfectant are to be placed above ceiling access hatches within the patient rooms and the therapy room as applicable.

o Bioesque Botanical Disinfectant is to be fog-applied in a concentration of 1-1.25 gallons per 1,500 sqft. of space in the above-ceiling spaces.

• Upon completion of the initial fogging, the above-ceiling space is to receive a second fogging using Bioesque Protect 90.

o Bioesque Protect 90 is also to be fog applied in a concentration of 1-1.25 gallons per
