​Temporary refuge definition
 
The temporary refuge (TR) 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. This contamination could be related to the escape of gas from drilling wells, from piping or storage / production facilities or to the production of toxic gases due to an explosion in the surrounding area.
 
The environmental conditions inside TR are constantly monitored to avoid the presence of contaminated air.
 
The TR facility needs to be designed with the following minimal characteristics:

• Have an area sealed from external air infiltrations
• Have a structure able to resist to nearby explosions without losing integrity and tightness.
• Have the capacity to assure the breathability of air inside protected area for a defined time needed to keep safe all personnel on board until the arrival of rescue transportation or until the return of external air to a safe condition.

 
This is achieved inside the sealed TR. Area as follow:

• Fully recirculated air conditioning system
• Safe area in overpressure respect to the external
• Entrance in the safe area protected by airlocks

 
The following equipment are installed inside TR:

• A reserve of breathable air
• A reserve of oxygen
• A CO2 reduction system

 
To maintain the correct required oxygen ration and to prevent the increase of carbon dioxide ratio inside TR, a reserve of breathable air and oxygen and a CO2 reduction system are installed inside the TR.
 
The TR consists in:

• A large area able to contain the POB, the minimum area will need to be of 1.5 sqm per person
• Two or more airlocks equipped with air washing systems and interlocked doors
• A fully recirculated air conditioning system area
• A medical area

 
TR will be equipped with the following safety systems:

• TR control/command panel including gas level monitoring console and the residual levels of air and oxygen in the air/oxygen bottles of the TR system
• ESD/F&G console unit: emergency shut-down and fire & gas console
• Smoke detectors
• Fire detectors
• Gas detectors
• PA/GA access point
• Telephone access point
• Communication point into each air-lock
• CCTV system
