No building should be considered capable of withstanding every possible explosion. The technically accurate term is blast-resistant building. Each structure is engineered for defined blast pressure, impulse and response criteria established for its intended application.

Blast-Proof Building
The Industry Leader of Blast-Proof* Building Rentals.
Protect personnel and support critical operations with rapidly deployable blast-proof buildings from Hunter Onsite. Available as standalone modules, connected complexes and specialty configurations, our blast-resistant buildings provide secure, functional space for demanding industrial environments.
Although commonly called a blast-proof building, the technically accurate industry term is blast-resistant building (BRB) or blast-resistant module (BRM). These structures are engineered to provide a defined level of protection based on specified blast pressure, impulse and response criteria.

What Is a Blast-Proof Building?
A blast-proof building—more accurately called a blast-resistant building—is a reinforced structure engineered to help protect occupants from specified explosion effects. Its design considers both overpressure and impulse, along with the building’s intended location, occupancy and required response level.
Unlike a conventional portable office or jobsite trailer, a blast-resistant building incorporates structural and mechanical features intended for use in identified hazardous environments.
✓ Reinforced steel construction: Structural walls, roof assemblies, framing and doors work together to resist specified blast loads.
✓ Blast-resistant doors: Reinforced door assemblies and specialized hardware help maintain the integrity of the building envelope.
✓ Controlled building response: The structure is designed for an established response level under defined pressure and impulse conditions.
✓ Industrial electrical and HVAC systems: Available equipment supports occupancy and operation in demanding site environments.
✓ Configurable interiors: Layouts can support offices, meeting rooms, break areas, permit functions, tool storage and other site needs.
Blast-proof vs. blast-resistant: No occupied building can be assumed to withstand every possible explosion. “Blast-resistant” is the preferred term because these buildings are engineered for defined pressure, impulse and response criteria rather than guaranteed protection under all conditions.
How Blast-Proof Building Ratings Are Determined
Selecting a building involves more than choosing a PSI rating. Blast pressure, impulse duration, response level, occupancy and placement must be considered together. A facility-siting study or qualified engineering assessment should establish the appropriate performance requirements for the location.
Blast Pressure | The peak overpressure applied to the building, commonly expressed in PSI. |
|---|---|
Impulse | The intensity and duration of the blast load acting on the structure. |
Response Level | The anticipated degree of structural deformation or damage under the specified load. |
Building Placement | The location and orientation of the building relative to identified site hazards. |
Blast-Proof Building Rental Made Easier
Hunter Onsite offers blast-resistant buildings for short- and long-term rental, helping facilities add protected space without committing to permanent construction. Units can be delivered individually or combined into larger complexes as operational needs change.
✓ Quick delivery: Rental units are available for efficient deployment to industrial sites.
✓ Roll-off placement: Many single modules can be delivered without requiring a crane.
✓ Flexible rental terms: Support temporary projects, turnarounds and longer-term operations.
✓ Scalable layouts: Add or reconfigure modules as workforce and space requirements evolve.
