temporary Refuge (TR) shelter (or called as safe haven cabin | toxic gas refuge (TGR)

1/14/2023

 
How to define a temporary Refuge (TR) shelter (or called as safe haven cabin | toxic gas refuge (TGR) | H2S temporary refuge shelter)?
A temporary refuge is a place or shelter where personnel will be adequately protected from relevant hazards while they remain on an installation following a major incident, and from where they will have access to the communications, monitoring and control equipment necessary to ensure their personal safety, and from where, if necessary, safe and complete evacuation can be affected.
The Temporary Refuge will switch HVAC from fresh air mode to full recirculation mode in case of potential toxic gas intrusion, fire damper closure activated by external gas detectors. The TR will also provide minimum breathable air concentration by air cylinders enough for above 1 hour or more. The Temporary Refuges is located to ensure the safety of personnel during the period of time that covers the call to muster until an incident has been investigated and controlled, or successful evacuation of the installation has been completed. The TR shelter have adequate medical and welfare facilities, as well as emergency communications.
The TR shelter is designed for external installation with a supply duct to the TR area interior. The TR shelter control panel is designed to be installed internally within the TR area. When the TR shelter is operational, the shelter is designed as a fail-safe system, i.e. should the shelter sustain damage or an air seal leaks, then clean air will leak out of the shelter rather than contaminated air being drawn in. 

​Why is the temporary refuge (TR) shelter (toxic gas refuge | safe haven cabin | H2S temporary refuge) needed? 
The most important purpose of a temporary refuge (TR) shelter (sometimes called as toxic gas refuge (TGR), safe haven cabin, H2S temporary refuge shelter, TR pressurization unit) is to keep the personnel safe. At a facility, such as chemical processing plant or a floating production storage and offloading (FPSO), or a floating vessel, offshore platform or a industrial manufacturer, there are typically large volumes of flammable and explosive chemicals being used, stored, proceeded and transported. These potentially dangerous situations should occur. Depending on toxicity or intensity of the chemicals, a chemical release or blast can cause severe effects to personnels. Toxic gases produced from an explosion or loss of containment can lead to disorientation, incapacitation, or death.
The temporary refuge has the double functions as dayroom during normal operation and as Temporary Refuge in case of emergency. The TR is used as normal control room, office space or even canteen when operated in normal function. In the event of a blast or chemical release etc emergency condition, when evacuation is not possible, the temporary refuge shelter provides a safe alternative and are an essential part of emergency management. Installing temporary refuge shelters such as safe havens, shelter-in-place and toxic gas refuge shelter, is a mitigation control to reduce the loss of life, and damage to property and equipment, when preventative control fails. When it comes down to it, these temporary shelters help to improve survivability. 
In response, TLS temporary refuge shelter (toxic gas refuge shelter, or safe haven) offers a safe secure “go-to” area for personnel ranging from multiple to hundreds in the event of toxic chemical release, fire, explosion or other hazardous emergency scenarios.
​
​How does Temporary refuge (or toxic gas refuge) work?
When escaping from hazardous areas, the temporary refuge shelter is activated via alarm scheduled during an emergency, which will serve as a shelter station for 1-4 hours or more hours. HVAC and positive pressure system protect personnel and equipment from critical outdoor conditions like explosion, chemical release including H2S, CH4 or other toxic gasses contamination, etc. The breathable atmosphere within the sealed temporary refuge shelter is provided to protect personnel.
