TLS offshore containers Int. offers an extensive range of containerized blast resistant modular / shelter that are cost effective and flexible. The containerized blast resistant shelters enhance worker safety within hazardous environments. These buildings provide a safe zone for employees and equipment within the process areas in the event of leaked vapor ignition or explosive risk.
Our blast resistant containers are available as standard 20ft, 30ft,  40ft or customized dimension. Those units can be joined together to form larger blast resistant modules.
Blast resistant modules are fitted with split type air conditioning. They have integrated ventilation shut down systems with an optional gas detection system. They also have the option of manual, security controlled or fully automated door system to ensure the appropriate solution.

TR which has been designed to protect against toxic gas include the following:

• Positively pressurized (minimum of 50Pa)
• Airtight
• Fresh air is stored air cylinder to ensure availability of air for the duration of TR considering maximum TR POB, potential leaks sources, door opening, etc
• Entrances with double sets of doors (airlock facility with air curtain to purge toxic gas trapped with personnel entering the airlock) and located as far as possible away from sources of H2S, interlock shall be in place to prevent both airlock doors being opened simultaneously or to alarm to warn of this condition. The location on the doors to buildings should be such that entry to the building is from side which is not directly facing to facilities to reduce the potential toxic gas ingress while in use.
• Doors shall be closed all the time except when in use. Or be automatic closing, for example by magnetic hold open, released on gas detection. Attention should be paid to avoid hazards with automatically closing doors such as trapped fingers, e.g. doors should be slow closing.
• HVAC shall be automatically shut off on detection of toxic gas at the air intakes, and dampers in the air intakes and exhaust shall close to shut in the building. Reliability of detection shall be determined as part of the design, and shall comply with the requirement for the protection.
• Toxic gas detectors shall be provided at HVAC inlet as well as within the airlock. Alarm provision shall be provided accordingly.
• A mechanism to allow manual initiation of HVAC shutdown from within the TR.
• TR leak tightness test shall be carried out to ensure the gas tightness and to confirm the air exchange rate considered in design of TR. 

We are pleased to get a order of H2S temporary refuge (TR) shelter from a Kazakhstan client. 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 shelter (TR) or toxic gas refuge (TGR) is designed for drilling platform, offshore barge, oil & gas, petroleum, and chemical industries. The temporary refuge shelter is designed to protect personnel against H2S gases and other hazardous gases that can appear in case of an uncontrolled release. The design of the TR is that everybody can rush into the shelter immediately without any time-consuming air-locking process. During the stay of the people inside the TR they can breathe normally from the atmosphere in the room. The shelter is protected by over pressurization during stand-by as well as during emergency.

​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.
