Why the Temporary Refuge (TR) Shelter (Toxic Gas Refuge | Safe Haven Cabin | H2S Temporary Refuge) is needed?

​Temporary shelter (TR) shelters (sometimes called toxic gas shelters (TGR), safe harbor pods, H2S temporary shelters, TR pressurizing units) are most important for ensuring the safety of personnel. Flammable and explosive chemicals are commonly used, stored, handled and transported in large quantities in facilities such as chemical processing plants or floating production, storage and offloading (FPSO), or in floating ships, offshore platforms or industrial manufacturers. These potentially dangerous situations should happen. Depending on the toxicity or intensity of the chemical, the release or explosion of the chemical may seriously affect persons. Explosive or closed loss of gas can lead to disorientation, incapacitation or death.
The temporary refuge has the double functions as dayroom during normal operation and as temporary shelter functions in emergency situations. The TR is used as normal control room, office space or even canteen when operated in normal situation. In the event of an emergency such as an explosion or chemical release, a temporary shelter is a safe option in the situation that evacuation is not possible and is an important component of emergency management. When preventive control fails, the installation of temporary shelters, such as safe havens, in-place shelters and toxic gas shelters, is a mitigation measure that reduces loss of life and damage to property and equipment. Ultimately, these temporary shelters help improve survival.
In response, TLS temporary refuge shelter (toxic gas refuge shelter, or Safe haven cabin) provides a safe "access" area for toxic chemical releases, fires, explosions or other dangerous emergencies, ranging from hundreds to hundreds of people.
