Cities - Blast-Resistant Modules

Protect personnel and support ongoing operations with blast-resistant modules delivered throughout Minnesota by Hunter Onsite. Our rental fleet includes BRMs in a range of sizes and floor plans designed to support industrial offices, break rooms, conference spaces, control functions, maintenance teams, contractors, and other essential onsite activities.

Standard blast-resistant buildings can be deployed quickly for temporary projects, while connected modules and specialty configurations provide additional flexibility for larger workforces and complex industrial sites. From planned turnarounds and shutdowns to ongoing facility operations, Hunter Onsite helps customers create safer, more functional workspace close to where the work is happening.

Choosing the Right Blast-Resistant Module for Your Site

The right blast-resistant module depends on workforce size, intended use, site placement, and project duration. Hunter Onsite offers BRM rentals throughout Minnesota, from individual 20-foot and 40-foot units to connected complexes and specialty configurations.

Consider Your Workspace Needs

✓ Number of personnel who will occupy the building

✓ Office, break room, meeting, control, or specialty use

✓ Need for individual rooms or multiple functional areas

Consider Your Site Requirements

✓ Available space and proposed building location

✓ Access for delivery and module placement

✓ Project schedule, rental duration, and potential changes in workforce size

Purpose-Built Blast-Resistant Modules

Hunter Onsite BRMs are purpose-built as blast-resistant structures—not converted shipping containers. Each unit is designed for demanding industrial environments and identified by its blast pressure rating and response level. Depending on the building and configuration, available modules may be rated for 8–10 psi at a medium-to-low response level.

Finished interiors, electrical outlets, communications connections, lighting, and HVAC create a comfortable, functional workspace for personnel. These features support Hunter Onsite’s goal of protecting people while keeping operations moving throughout Alabama.

What Guidelines Apply to Blast-Resistant Modules?

There is no single rating or configuration that makes a blast-resistant module appropriate for every facility. BRM selection and placement should be based on a site-specific hazard assessment, the module’s engineered blast rating, intended occupancy and applicable facility requirements.

The American Petroleum Institute provides widely recognized recommended practices for managing hazards associated with buildings at process facilities:

API RP 752 addresses permanent process-plant buildings and certain portable buildings intended for long-term use in a fixed location.
API RP 753 addresses portable buildings located at process plants.

These recommended practices consider risks associated with explosions, fires and toxic-material releases. Facility owners and their qualified safety and engineering professionals are responsible for determining the appropriate building type, rating and location for each application.
