In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations could provide an ignition source, due to electrical arcing, or high temperature. Standards and regulations exist to identify such locations, classify the hazards, and design equipment for safe use in such locations. please find more information from wiki link and download hazardous areas difinition reference.
The electric facilities installed in hazardous areas should be explosion proof certified. please refer to related information from the link in our website.

The Temporary refuge shelter is a place or sanctuary where persons are adequately protected while remaining in the installation in a major disaster such as chemical release, explosion, etc, it can protect people from associated risks, and people from there to communicating, monitoring and controlling equipment necessary to ensure their physical safety, and to safely and completely evacuate from there if necessary.
The temporary refuge shelter switches HVAC from fresh air mode to full recirculation mode to prevent potentially toxic gases from entering and the external gas detector activates the fire valve to close. TR will also provide a minimum breathing air concentration from the compressed air cylinder for at least 1 hour or longer. The location of the temporary shelter ensures the safety of personnel for a period to the convening of the call until the incident has been investigated and controlled or equipment has been successfully evacuated.
The temporary refuge shelter has adequate medical and welfare facilities as well as emergency communications.TR enclosures are designed for external installation and are equipped with air supply piping to the interior of the TR muster area. The TR shield control panel is designed to be installed internally within the TR area. When TR shelter went into operation, it was designed as a fail-safe system, meaning that if the shelter suffered damage or an air seal leak, clean air would leak out of the shelter instead of being inhaled by contaminated air.

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.

The tertiary recovery has become the dominant technique for the stable production of old oilfields in the Shengli Oilfield. The cumulatively incremental oil was up to 11.50 million tons by the end of Mar/2006. Chemical flooding has developed from single polymer flooding to multiple compo und flooding systems in the oilfield, and a complete set of chemical flooding with the oilfield's characteristics was formed. The tertiary recovery is facing some major problems, such as inadequate high-quality resources of the polymer flooding, replacement difficulty and unbalanced development of the tertiary recovery technology, and great resulted differences among the chemical-flooding implemented units , etc. The chemical flooding technology and the ability to innovate new products should be strengthened. The developmental space of tertiary recovery should be widened through continuously extending technical storage. The polymer-injection project should be well managed so as to enhance the effect of water decreasing and oil increasing. The intensive pilot study will make the tertiary recovery technology replacement faster.
TLS is honored to work as a partner of the subcontractor involving the Shengli oilfield project. The pressurised MCC shelters manufactured by TLS are used in the oilfield.

The purpose of a temporary refuge shelter (or safe haven, H2S refuge shelter, or shelter in place) is to keep you safe when a chemical release or blast cause severe health effects. Toxic gases produced from an explosion or loss of containment, when inhaled, can lead to disorientation, incapacitation or death.
Two protective actions commonly used in the event of a blast or chemical release are evacuation or to seek temporary refuge in a shelter in place or safe haven. Time, size of the hazard, and location are just a few variables which can impact your ability to evacuate safely. When evacuation is not possible, the shelters will provide a safe alternative and are an essential part of emergency management.
Installation protective shelters such as safe havens, blast-resistant buildings and SIPs, is a mitigation control to reduce the loss of life, and damage to property and equipment, when preventative controls fail, When it comes down to it, these shelters help to improve survivability.

When the gas protection function is enabled, the high-pressure air would be depressed by depressurizing system and then fresh air would be supplied to the main room. A micro-positive pressure of 50pa would be kept in the main room and 25pa in the air-lock area. Due to the internal pressure in the temporary refuge shelter is slightly higher than the atmosphere pressure, the internal air will vent through the check valve and the hazardous gas will be blocked outside.

The Temporary Refuge (T.R.) shelter (or safe haven shelter, toxic gas refuge) is a safe and sealed area for the people protection during environmental contamination from poisonous gases which can be present in operating areas where oil and/or gas research, extraction and pre- production are performed. The temporary emergency shelter should be provided on all offshore installations. It is required to have a defined performance standard related to its survivability when exposed to a major accident that includes, but is not limited to, ingress of smoke, flammable and toxic gas. HVAC forms an essential part of this. As the TR is the last space for the crew before abandoning the vessel, rig or platform, the HVAC system should create and maintain a comfortable and safe indoor condition free of any explosive and/or toxic gas-air mixtures. The air quality and pressure inside the TR-zone is than of top priority. This can be created by the special TR pressurisation shelter.
