The present disclosure is directed to a facility design to minimize viral load and, more specifically, to a static building structure having various features to reduce the risk of viral infection, particularly in an athletic locker room area.
Although some recommendations are to maintain six feet of distance between people to reduce risk of disease transmission (i.e., “social distancing”), some experts say this may not necessarily be effective in stopping the spread of disease, particularly in indoor environments. Some recommendations during times of high viral risk are for six feet of distancing between athlete lockers, with athletes wearing mask protection. This is not generally practical, easily applicable, cost effective, or truly impactful in control of pathogen spread. Upon entry to a locker room, e.g., at halftime or in between periods of play, athletes are often breathing heavily and not in a state of quiet respiration (a state assumed in typical six-foot distancing recommendations). Sweat and other bodily fluids from athletes have frequent contact with surfaces in a locker room area, and restroom facilities present a high-risk situation for aerosolization of pathogens. Locker rooms typically present inherently tight, high-risk spaces that require more creative strategic plans beyond traditional social distancing and shielding measures.
In addition, many janitorial protocols call for equipment and cleaning materials that have fragrances or other additive ingredients. However, the presence of cleaning products in the air can be harmful to the lungs, which can be detrimental to the performance of elite athletes. For elite athletes, even a small impact on a player's physiology has the potential to negatively impact athletic performance.
Further, fabric face coverings (masks) are not optimal for player recovery following strenuous exercise as they limit the ability for efficient carbon dioxide exchange. In addition, mask materials are typically absorbent, which poses an issue when a player is perspiring and breathing heavily. Once the mask gets wet, its effectiveness at reducing risk of communicating pathogens is reduced, as well as the player's ability to breathe while wearing it. Also, fabric masks are generally prohibitive to athlete rehydration. Further, masks cannot be worn in shower areas, and do not adequately protect the players' eyes from sprayed droplets or finger to eye transmission.
In addition, clothing and personal belongings are a high touch, high risk for the spread of pathogens. Athletic clothing and gear is of particularly high risk because of the amount of bodily secretions associated with sports, as well as the amount of physical contact between athletes. Further, the handling of laundry in a locker room can be a source of pathogen spread, as locker room staff often provide laundry services, including washing all player uniforms as well as towels, etc. In addition, some personal items, such as sunglasses or hats are worn on the face/head and present a high risk of transmission of pathogens. It is difficult to cleanse clothing and personal belongings with as much frequency as needed to minimize the risk of pathogen transmission.
Also, in the bathrooms, the toilet flushing process results in an aerosolized plume that presents increased risk for pathogen spread. In addition, sinks and soap dispensers can have contact surfaces that promote the spread of pathogens, as well. Further, shower areas present an environment including a large amount of moist air with more rapid spread of droplets.
The present disclosure addresses one or more of the issues identified above.
In one aspect, the present disclosure is directed to a static building structure including an athletic facility. The facility may include a locker room area having disposed therein one or more lockers including ultraviolet lamps. In addition, the facility may include one or more high flow ultra high efficiency particulate air (HEPA) UV-C purifiers. Further, the athletic facility may have a shower area disposed adjacent the locker room area and including one or more far-UV-C lamps.
In another aspect, the present disclosure is directed to a method of minimizing viral load in an athletic facility locker room. The method may include cleansing surfaces without spraying disinfectants onto a cloth or the surface to be cleansed; wearing face shields while residing within the athletic facility; and utilizing third party verification to confirm that anti-viral protocols are being followed.
In another aspect, the present disclosure is directed to a disinfecting locker. The locker may include an enclosure including therein at least one UV-C lamp configured to irradiate the contents of the enclosure. In addition, the locker may include one or more UV-C transparent structures. Further, the locker may include one or more UV-C reflective surfaces.
Other systems, methods, features and advantages of the embodiments will be, or will become, apparent to one of ordinary skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description and this summary, be within the scope of the embodiments, and be protected by the following claims.
The embodiments can be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale, with emphasis instead being placed upon illustrating the principles of the embodiments. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.
The present disclosure is directed to a static building structure including various features to reduce the risk of viral infection. In particular, the description below is directed to implementation of risk reduction features and measures associated with an athletic locker room area. According to the present disclosure, locker rooms can be provided with several features and occupants can adopt various protocols to minimize the risk of infection. However, it will be understood that these measures may be applicable to other types of facilities. Thus, these features and protocols may be applicable various types of indoor facilities. For example, the features and protocols discussed below may be applicable to locker rooms and other changing areas, restroom/bathroom areas, athletic training rooms, fitness centers, weight rooms, conference rooms, video review rooms, and various other indoor areas associated with sports and athletic facilities and/or other types of indoor facilities.
Disinfecting Locker Design
Exemplary disinfecting lockers according to disclosed embodiment may have multiple disinfecting features, such as UV-C lighting, UV transparent shelving, and an electromechanical system configured to initiate operation of the UV lights when the door is closed and prevent operation of the UV lights when the door is open.
As also shown in
The UV-C lamps used in the disclosed lockers may be configured to emit ultraviolet light with a wavelength in the range of 255 nm to 280 nm. In some embodiments, the lamps may be LED type lamps.
In order to facilitate the application of UV-C light to various areas of the enclosure, one or more walls of the enclosure may be reflective of UV-C light. For example, as shown in
Also, in some embodiments, interior supports, such as shelves and/or clothes hanger rods may be formed of UV-C transparent material so as to avoid blocking the UV light from being delivered about the enclosure. An exemplary UV-C transparent material from which such supports may be formed is quartz. For example, as shown in
In some embodiments, UV-C transparent shelving may be utilized in order to sanitize the underside of the user's belongings. For example, in some embodiments, a UV-C lamp may be positioned directly under a UV-C transparent shelf in order to disinfect the underside of the user's glasses or the soles of their shoes.
The locker may also include a locking system with automatic locking and unlocking. For example, the system may include a detection device, such as a proximity sensor, that detects the presence of a fob carryable by a user. When the fob comes within a few feet of the locker, the locker may unlock automatically. When the fob is taken more than a few feet away from the locker, the locker may lock automatically. In some embodiments, the system may be configured to detect the proximity of a smartphone of a user. In some embodiments, there may be a feature where one can wave a foot or hand near a portion of the locker and it will unlock and possibly open.
In some embodiments,
Gear Sanitization
In some embodiments, sports-specific equipment that is difficult to cleanse may be storable in a dedicated UV-C enclosure. For example, football helmets and padding cannot be laundered with uniforms and other clothing. A locker may be configured with one or more compartments dedicated for irradiating such equipment with UV-C light.
As shown in
Similarly, third compartment 615 may be configured to house and disinfect football shoulder pads 640, and possibly other padding. As shown in
In some cases, certain equipment may be located in its own dedicated area. For example,
As shown in
Facility Configuration
Anti-viral lockers, such as those discussed above, may be incorporated into an athletic facility, e.g., a locker room.
Airflow
Rather than utilizing harsh cleaning products that could be damaging to athletes' lungs, efforts should be made to keep cleaning products as nontoxic as possible and avoid unnecessary inhalation of substances. One way to provide disinfection without harsh cleaning products is to improve air quality using high flow ultra high efficiency particulate air (HEPA) UV-C (ultraviolet lamp) purifier units. This equipment can be easily retrofitted in existing locker rooms as these units can be brought in and simply plugged into a preexisting electrical outlet. These units have the ability to turn over room air within the locker room at a rapid pace (within minutes), and are viricidal to pathogens in the air. This not only minimizes contact of droplets with players' faces, but also minimizes the volume of droplets potentially settling on the ground and other surfaces.
Moreover, along with the use of these units, airflow analysis is conducted for site-specific flow patterns, ensuring that air flow is directed away from individuals. In general, the pattern of flow of air down the row of lockers across multiple players is to be avoided. Units are strategically placed such that air is drawn away from people rather than crossing through a group. Specific room volume is matched with an appropriate unit or units to ensure strategic laminar flow of air away from personnel. Further, units are strategically placed specific to the room to control airflow.
As shown in
In addition, the other adjacent areas may include additional HEPA UV-C units. For example, in some embodiments, shower area 815 may include a fifth HEPA UV-C unit 835. In some embodiments, toilet area 820 may include a sixth HEPA UV-C unit 836. Further, in some embodiments, laundry area 825 may include a seventh HEPA UV-C unit 837.
Shower Area
In order to keep up with the high moisture environment in the shower area, the shower area may include one or more far-UV-C lamps in the ceiling or walls. Far-UV-C has the ability to maintain germicidal properties, while remaining safe for human exposure. As shown in
Laundry
A designated separate area for dirty linen placement is provided. In addition, separate staff wearing higher level PPE are to be responsible for properly removing and washing soiled linen. As shown in
Bathroom Protocols
In order to prevent the plume of droplets created by flushing toilets, the disclosed toilets may include a feature that prevents flushing unless the lid is down. As shown in
In addition, toilet area 820 may include one or more urinals 865 that are continuous flow or no flow in order to avoid the flush mechanism altogether. Further, all sinks (870) and soap dispensers may have no-touch operation. For example, sinks 870 may be motion activated for touchless use.
Surface Control
In conjunction with airflow and air treatment, the cleaning of locker room surfaces is to be done often. Surfaces will be regularly wiped specifically with products that do not have fragrances, additives, or unnecessary ingredients. For example, simple solutions of water and 70% alcohol may be used as an option that is both economical and non-toxic. Any possible skin irritant or substance that may cause a skin hypersensitivity reaction over time is to be avoided. Further, whenever possible, cleaning solution is to be put on a cloth and the cloth will be used to wipe surfaces. This minimizes fumes in the locker room environment.
In addition, any new proposed floor cleaning products are to be pre-tested in order to ensure that the product does not build up on cleats in a manner that makes their use less effective. For example, products may be tested to ensure that cleaning products on the soles of cleated shoes do not cause the cleats to become clogged with dirt and mud more easily.
Also, aerosolized products, sprayers, and ozone products are not to be used during times when athletes access the locker rooms, and can only be used when there is an abundance of time far beyond the minimum requirements prior to the athletes accessing the locker rooms, in order to allow sufficient time for adequate air exchange in the space to occur prior to player reentry.
Personal Protection
In lieu of fabric or paper masks, face shields are to be used by the players. Face shields stop droplets from spreading from a person's mouth to the adjacent surroundings. In addition, they protect the wearer's eyes, nose, and mouth from droplets in the environment. Further, face shields can allow rapid exchange of carbon dioxide, as they do not inhibit the athletes' breathing as much as a fabric mask. It will also be noted that face shields can be waterproof, easily reused, and extremely cost effective. While using face shields, players can communicate clearly with one another, easily move to the showers or restrooms, and even sip a beverage to rehydrate using a straw.
Proper sizing of face shields is to be utilized. In particular, face shields should extend below the chin anteriorly, to the ears laterally, and there should be no exposed gap between the forehead and the shield's headpiece.
In some sports that require helmets, an athlete can place on a face shield immediately upon removing their helmet, and wear this shield throughout all locker room activities ensuring uncompromised and continuous protection.
Validation
In order to ensure successful adaptation of these protocols in the locker room environment, the techniques described above may be validated by a third party. For example, the third party may test air quality for safety and surfaces for traces of pathogen.
This strategic plan features elements that are widely applicable to a variety of locker room designs. A large remodel is not necessary for successful implementation. As described above, locker room design requires high attention to detail of air, surfaces and the athletes. While traditional six-foot distancing measures may not be effective or practical in a locker room setting, strategic use of germicidal technology, cleaning techniques, and personal protective equipment (PPE) allows for a safe and clean environment without compromising the athletic abilities of the player.
