FOX Corporation requires the implementation of specific steps, as specified on this Procedure, when water intrusion has occurred into any employee-occupied building.

1.0 SCOPE

This document applies to all FOX Corporation (FOX) locations where a water intrusion event has occurred. The event may impact various building construction materials and ceiling components within the interior of the affected building(s).

2.0 Definitions

Water Intrusion Event – An incident involving the incursion of water into spaces that are occupied or can be occupied. The incident may involve clean or contaminated water that results from, but not limited to, flooding, leaks, or spills.

Gray Water – Water containing a significant level of contamination and has the potential to cause discomfort or sickness if consumed by or exposed to humans.

3.0 Responsibilities

In addition to required Environmental, Health and Safety (EHS) Program responsibilities discussed in EHS001, EHS Policy, the responsibilities described below are necessary to ensure the effectiveness of the procedure.

3.1 Facilities Maintenance

Facilities Maintenance personnel are responsible for following the appropriate protocols defined by this procedure as it applies to the nature of the work areas affected.

Facilities Maintenance will ensure that employees performing in areas where water intrusion has occurred are trained in this Procedure

3.2 Employees

All Fox employees will observe the requirements specified in this Procedure

3.3 Environmental, Health and Safety Department

The EHS Department will perform a periodic review of this Procedure (at minimum, annually) to ensure that all procedures are current and meet established regulatory requirements.

4.0 Procedure

Evidence of water intrusion into work areas presents a variety of hazards to workers due to potential exposures to various materials that may be affected by contact with water. Prevention of exposure relies upon proper removal of the material prior to conducting other work operations.

4.1 General Requirements

The removal process will be performed in accordance with the following:

a. Prior to the start of the removal process, a Job Safety Analysis (JSA) must be conducted by the Department performing the work, in accordance with EHS 104, Job Safety Analysis.

1. The JSA will be used to determine if other hazards that might not be readily apparent need to be considered during the removal process.

2. This analysis must identify all physical, biological, radiological, mechanical, electrical, and other potential hazards.

3. Questions to be considered include:

· Does high electrical voltage exist in the immediate area?

· Will equipment in the area pose a point of operation or power transmission hazard?

· Does a fall hazard exist because of the material’s location?

· Is adequate lighting available for the removal activities?

Upon completion, the JSA must be submitted to the EHS Department for review and approval.

b. All employees involved in the cleaning process must be made aware of the safety and health hazards and PPE requirements contained in the JSA, prior to the start of cleanup activities.

c. Protective measures might include lockout/tagout considerations (see EHS 403, Lockout/Tagout), and confined space entry considerations (see EHS 404, Confined Spaces).

4.2 Training

Department Heads will ensure that those employees performing work activities in areas where water intrusion has occurred have been trained in this Procedure.

4.3 Specific Requirements

To preempt microbial growth, immediate action by Facilities Maintenance personnel is required following a significant rain event, flood or water leak. The following list of considerations, (if carried out quickly and carefully) should prevent or significantly reduce the likelihood of further damage to building materials.

1. If applicable, shovel out the worst of the mud and silt before it dries. Use a hose if necessary.
2. Before the area has dried out, scrub the floors and woodwork with a stiff brush, plenty of water, a detergent, and a disinfectant. A solution of 1/4-cup liquid chlorine bleach per one gallon of water makes an adequate disinfectant. Test a small area for colorfastness. Remove the mud and silt from corners, cracks, and crevices.
3. Clean glued-down carpet in place before attempting to pull it up. Use a wet/dry vacuum to extract the water and then shampoo the carpet with detergent.
   Glued-down carpet may be adhered to asbestos-containing flooring material; confer with EHS before pulling up the carpet. If the carpet is not glued down, roll up the carpet and move it to another location for cleaning. Remove and discard the spongy carpet padding. After the carpets are rinsed, quickly dry them by turning on the heat and using dehumidifiers. Wet carpet should be thoroughly dried within 48 hours; if this is not possible, discard the carpet. Materials contaminated with sewage or gray water must be completely discarded.
4. If a professional carpet cleaner is retained, a steam cleaning method (hot-water extraction) is preferred.
5. After the carpet is thoroughly dried, vacuum the area. Give floors a thorough final washing with a non-sudsing cleaning product. Repeat the drying
   process. Vacuum again. Until the floors are thoroughly dried, runners should be placed on tile, or other slippery floors to help prevent slips and falls. The musty smell can be reduced by following these procedures:
6. Sprinkle baking soda over the carpet, working it in with a broom or sponge mop.
7. Leave the baking soda treatment on overnight.
8. Vacuum the baking soda out. Vacuum twice, moving back and forth in a different direction the second time.
9. Walls may wick up and retain water. Water may also accumulate in the interstitial spaces between walls. Prior to disturbing wall systems (drywall, baseboard), confer with EHS to determine if asbestos is an issue. Remove all wet baseboards and drill holes between studs a few inches above the floor to drain these areas. Inspect the drywall and the interstitial spaces to determine if it is wet. Use a moisture meter to determine the extent of penetration.
10. Wet walls must be removed to at least the flood level, or dried by cutting holes at strategic locations to increase air circulation. Serious fungi contamination can occur on the back of the drywall if left wet. Cut several inspection holes in the walls to determine if the wall interior is wet.
11. Walls containing fiberglass insulation must be removed. Check the metal track for water accumulation.
12. Wet ceiling tiles must be dried or discarded.
13. Water can flow a considerable distance on hard ceilings. Thoroughly inspect hard ceilings that may be wet. Dry or remove all wet ceiling gypsum board.
14. The area under floor-mounted cabinets is difficult to dry out. The cabinets must either be lifted or panels removed from the cabinet to allow for water removal and drying.
15. Paper products and boxes must be completely dried or discarded.
16. Electrical circuits in the walls under the floors and in ceilings may be wet. These should be inspected by a qualified electrician.
17. Computers and other electronic equipment should be inspected by a qualified technician before they are re-energized.
18. Good ventilation is essential to the rapid removal of water vapor. Open windows and doors and/or adjust the ventilation equipment to provide as much air exchange to the outside as possible or use blowers and dehumidifiers until the carpet is dried. Use a dehumidifier to extract water out of the room air and maintain relative humidity to less than 70 percent (less than 60 % is desirable).
