MineARC’s ChemSAFE Blast Resistant Buildings (BRBs) are designed to provide protection from an industrial hazard such as a blast or flammable gas release. The open space pre-fabricated steel buildings can serve as work spaces or break rooms for general day-to-day use.
- Multi-use building design
- Up to 10psi blast rating
- Integrated life support options
- Network connection, smoke detectors
- ChemSAFE Custom Projects
ChemSAFE conversion of an existing room to Safe Haven allows occupants to shelter inside buildings, providing high levels of protection from toxic release.
- Customised modular construction
- Integrated life support options
- Electrical packages available
- Custom capacities

A petrochemical shelter or safe haven is a sealed environment, in which you can take shelter during a hazardous event when evacuation is not possible. These shelters help protect personnel in disasters (fires, explosions, and gas releases), as well as minimise the risk to, and enhance the effectiveness of, emergency responders.
To be classified as a safe haven, a refuge must:
- Be a sealed, enclosed environment with 0% air changes per hour (ACH)
- Provide a source of clean, breathable air by removing carbon monoxide and carbon dioxide from the internal atmosphere and adding in medical grade oxygen
- Control the internal environment, through heating and cooling
- Have a back-up supply of power to support the internal systems if mains power is lost
Petrochemical Safe Havens can be portable, modular, or developed in new or existing buildings. They are purposefully-designed for specific hazards at each petrochemical site.
You may also have heard a Safe Haven called:
- Shelter-in-Place (SIP)
- Protect-in-Place (PIP)
- Refuge Chamber
- Chemical Shelter
- Safe Refuge
- Toxic Gas Refuge
- Temporary Refuge

Increasing Blast Effects Comparison
Possible effects on the human body from increasing blast pressure:
Threshold for eardrum rupture
50% probability of eardrum rupture
90% probability of eardrum rupture
Threshold for internal injuries by blast
Threshold for lung haemorrhage
50% probability of fatality from lung haemorrhage
90% probability of fatality from lung haemorrhage
Immediate blast fatalities
Injuries by glass fragments
Threshold for skin lacerations by missles
People knocked down by pressure wave
Possible fatality by being projected against obstacles
50% probability of fatality from missile wounds
100% probability of fatality from missile wounds
People standing up will be thrown a distance
Overpressure Thresholds for Structures and Equipment
Threshold for glass breakage
Collapse of non-reinforced concrete or cinderblock walls
Collapse of industrial steel frame structure
Displacements of pipe bridge, breakage of piping
Displacement of cylindrical storage tanks, failure of pipes
Total destruction of buildings, heavy machinery damage
When evacuation is not possible, Petrochemical shelters provide a safe alternative and are an essential part of emergency management. Shelters should be located in proximity to potential blast or gas release zones.
