Medical Shelters with Negative Pressure Isolation Systems for the Fight Against COVID-19
Alaska Structures® (Alaska) is the world’s leading provider of rapidly deployable medical shelters and mobile field hospitals. When equipped with negative pressure isolation systems (NPIS), these medical systems designed to treat injured soldiers and enhance return-to-duty (RTD) efforts are quickly transformed into advanced patient isolation wards and treatment facilities. HEPA and UV germicidal filtration remove 99.984% of particulates 0.3 microns or greater in size, creating a safe space for the testing, isolation, and treatment of patients with COVID-19 or other airborne infectious disease.
The Alaska Negative Pressure Isolation Shelter is available in many different configurations, including isolation facilities with single and double bathrooms (1 or 2 sets of toilets and showers).
- Alaska Medical Shelter System (20 ft. wide x 32.5, 40.5, 45.5 or 52 ft. long)
- Vestibule Entry (7 ft. wide x 8 ft. long) with Bump-Through Doors (48 in. wide x 84” high)
- Alaska ECU™ (5-ton capacity, available in 50 or 60 Hz)
- Negative Pressure Air Scrubber (with HEPA and UV Germicidal Filtration)
- Negative Pressure Sensor / Alarm System (monitoring system with audible and visual alarm, adjustable negative pressure range of 0.01 to 0.04 inches SPWG)
- Isolation Partition (variable size patient isolation area and anteroom, optional partition with personnel door for isolation facilities with bathrooms)
- Internal Liner System (optional supplemental insulation packages available)
- Non-slip Vinyl Floor and Sub-Flooring System
- Lighting and Electrical Distribution System (fluorescent or LED, available in 50 and 60 Hz)
- Optional Isolation Facilities with Bathrooms (include portable sink, portable shower, portable toilet, benches, clothes bars, plug-and-play water connections, water and sewage pumps, water heater, and bladders for potable, gray, and black water)
When needed, the Alaska Negative Pressure Isolation Facility can easily be converted to a positive pressure cleanroom.
Maintaining a State of Readiness During the Coronavirus Pandemic
With the ongoing threat of COVID infections, the United States Armed Forces is currently under a stop movement order directing all DoD uniformed, civilian personnel, and their families moves be postponed to June 30, 2020. Once the permanent change of station (PCS) ban has been lifted, and military personnel begin to resume traveling, it will be important for military bases in the US and overseas, as well as forward operating sites (FOS), and military hospitals and health care facilities be prepared to handle a potential surge of patients in order to maintain a state of readiness and stop the spread of COVID-19.
The Alaska Negative Pressure Isolation Facility can be operational within 60 minutes, can withstand winds up to 100 MPH, snow loads to 20# PSF, has a proven field life of 10 years, and when not in use, is easily stored in reusable Alaska Containers – with a storage life of 20 years. Alaska Structures makes it possible for maintaining a state of readiness by equipping military installations with the ability to quickly respond to COVID-19 or other airborne infectious diseases, such as Severe Acute Respiratory Syndrome (SARS-CoV), Middle East Respiratory Syndrome (MERS-CoV), influenza (Flu) outbreaks, including an infectious outbreak of Ebola.
In addition to quickly establishing COVID testing, isolation and treatment facilities outside of hospitals and health care systems, the Alaska Negative Pressure Isolation Shelter can also be configured as a medical support shelter. In such cases, the Alaska Shelter System is put in-place to reduce the strain placed on hospitals and the health care system during a large-scale event or medical surge, like the Coronavirus pandemic. Alaska medical shelters and medical support shelters are capable of providing advanced-level care, but in this situation are typically used to support patients who are not at risk of COVID-19 infection, but still require medical attention.
Exceeding Expectations and CDC Guidelines for Airborne Infection Isolation (AII)
The DoD is following the guidelines established by the Centers for Disease Control and Prevention (CDC) to reduce the spread of the Coronavirus. The CDC mandates the use of negative pressure Airborne Infection Isolation (AII) in the event a patient has contracted an infectious disease.
The Alaska Negative Pressure Isolation Facility meets and exceeds the guidelines for Airborne Infection Isolation. The system is capable of the following:
- Controls all three elements of indoor air quality: particles, biologicals, and gas phase volatile organic compounds (VOCs).
- Filters 100% of the return air and removes 99.984% of particulates 0.3 microns or greater in size.
- Removes ambient VOCs at a minimum rate of 30% each pass.
- Alaska ECU™ exceeds the 12 air exchanges (ACH) per hour required by the CDC guidelines.
The Alaska Negative Pressure Isolation Facility is proudly made in the USA and is Berry Amendment compliant.
