ChemSAFE Sealed Rooms

Intended for petrochemical facilities that do not have the physical space for a portable Safe Haven; ChemSAFE Sealed Rooms provide a convenient means of protecting personnel from a toxic gas release.

These modular constructed shelters are designed to have minimal air changes per hour (ACH). The incorporation of life support systems such as the MineARC AirGEN and AirMAX ensures occupants remain safe for the entire duration of the petrochemical emergency.

ChemSAFE Sealed Rooms

AirMAX Life Support

Non-built-for-purpose buildings in petrochemical facilities generally 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 petrochemical building, the level of protection provided to the occupants diminishes with time.

A safer and more economical alternative is to seal smaller existing rooms within a larger building.


There are cost-effective means to create a “very tight” room (<0.04CFM per square foot of floor space) within a petrochemical facility 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.


The MineARC AirMAX Life Support System combines two critical life support features. A Positive Pressure Maintenance System (PPMS) to keep toxic and hazardous gases out, and a supplemental oxygen delivery system to replenish the air. Optional Aura-FX Gas Monitoring ensures that external contaminants cannot enter the sealed room, while alerting users to changes in gas 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 shelter-in-place for a specified duration.


AirBANK provides rapid pressurization, which is activated and maintained using the AirBANK CONTROL via a simple HMI touch screen. MineARC’s integrated Aura-FX Gas Monitor ensures breathable air remains within acceptable limits. Alternatively, ChemSAFE Sealed Rooms can be fitted with supplementary oxygen and carbon dioxide scrubbing systems.

The AirBANK Pressure System is designed to store 11 4,500psi or 6,000psi cylinders, and allows any number of cylinder racks to be daisy-chained as required. Each rack is leak protected by a check valve and electric solenoid, and features a panel mounted gauge to display the high and low pressure level of the unit.

The remote activated AirBANK CONTROL is designed to maintain a life sustaining environment via a differential pressure device. Contained in a wall mounted NEMA-Rated enclosure, the unit features an HMI screen that monitors cylinder pressure levels; alarming when levels fall below the acceptable limit.

AirBANK CONTROL features an active by-pass of the system if internal gas levels are not within breathable air limits. The Aura-FX monitors and displays gas levels in real-time, including site-specific toxic gases if necessary.

AirGEN Scrubbing System

Depending on the designated occupancy of the petrochemical facility's shelter-in-place 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.


Standalone CO2 and CO scrubber air regenerative system

Humans consume oxygen and expire carbon dioxide (CO2) as part of normal respiration. In high enough concentrations, CO2 can cause serious injury, leading to a loss of consciousness and eventually death. Removal of CO2 is therefore a vital necessity for any shelter-in-place location, especially where CO2 concentrations exceed one percent over the entrapment duration.

The AirGEN is simple to operate with only a single switch and is powered from its own internal battery supply.

The MineARC AirGEN is compact in size, stores for extended periods, and is easy to operate.

The addition of a scrubbing system permits a shelter that is ventilated from the outside to be converted to a fully isolated environment, protected from external hazards.

Aura-RT Remote Gas Monitoring

The Aura-RT series is reinventing digital gas monitoring for petrochemical facilities. The Aura-RT and GuardIAN have been adapted into robust, weather-proof enclosures to allow for reliable gas monitoring and clear alarming even on the busiest of facilities. The independent Aura-RT, GuardIAN and speaker/strobe enclosures enable maximum flexibility where gas sensing is critical and where personnel can benefit most from displayed information and alarms.


The Aura-RT audible alarms use voice guidance to direct workers of the necessary actions they should take during an emergency. The GuardIAN interface and visual alarms can be custom-configured to assist workers in navigating to the nearest safe haven through displayed graphics or directional lighting to reduce hesitation and confusion in an emergency.

The Aura-RT Remote has the ability to accurately monitor up to four gases at once via a series of user-friendly digital screens. The Aura-RT Remote provides real-time external gas monitoring data via the GuardIAN dashboard. > NEMA 4X > Multi-Gas Sensing; O2, CO, NO, NO2 > On-screen gas level monitoring > On-screen alarm and pre-alarm status > Alarm-indicating enclosure back-lighting

The speaker and strobe combination is driven by built-in Aura-RT alarm outputs to provide clear indications during alarm and pre-alarm states. During alarm, the speaker will use voice prompts to announce the alarm and give instruction to those affected. Voice commands can be customized to suit site requirements.

> Remote mounting for best line-of-sight and audible placement near workers
> Audible alarms – Pre-alarm tone and voice-command alarm prompts
> 360° alarm strobe

The GuardIAN-Remote enables real-time monitoring that continuously displays gas and alarm status as reported by the Aura-RT. By utilizing the GuardIAN network, each GuardIAN-Remote display has access to information from all connected devices, including Aura-RT Remotes from differnt locations in the mine. The GuardIAN-Remote will provide confidence that the designated areas of interest are monitored and ready at all times.
