Life Support Systems​

AirMAX Life Support System ​

The AirMAX Life Support System design is for non-built-for-purpose buildings that do not meet acceptable leak tightness for shelter-in-place. With ventilation shut down, a typical building can have up to five air changes per hour or higher depending on wind speed. Door operation as people enter can potentially bring additional contaminants from outside the shelter. As contaminated air infiltrates a building, the level of protection provided to the occupants diminished with time.

A safer and more economical alternative is to seal smaller existing rooms with a larger building. There are cost-effective means to create a “very tight” room (<0.04CFM per square foot of floor space) within a building by using specifically designed components such as clean room ceiling tiles, sealing doors, and vestibules. These tightly sealed rooms, however, cannot be occupied for long periods without the risk of occupants producing a high level of carbon dioxide and dangerously reducing oxygen levels.

AirBANK Pressure System​

A critical requirement for any petrochemical shelter-in-place location is maintaining internal positive pressure in order to prevent the ingress of toxic and hazardous gases resulting from an accidental chemical release. MineARC’s AirBANK Pressure System offers a simple modular solution; ensuring occupants remain safe inside of a designated pressurised shelter for a specified duration.

AirGEN Scrubbing System​

Depending on the designated occupancy of the petrochemical facility’s sealed room location and volume, CO2 removal may be required. The MineARC AirGEN is a standalone air regenerative system that ‘scrubs’ the air inside of an enclosed location, effectively cleaning it so occupants can breathe.

Shelter-in-Place Integrity Testing ​

Integrity testing can identify leaks within a room before converting the area into a sealed, Shelter-in-Place (SIP). Buildings are typically constructed to provide natural or forced ventilation to allow permanent occupancy. Structural features such as large exposed windows and surfaces present challenges for ensuring protection during a blast event and subsequent chemical release.
