Cities - Blast-Resistant Modules

Blast-resistant module rentals are available for delivery throughout Maine from Hunter Onsite. Designed for refineries, petrochemical facilities, chemical plants, power generation sites, manufacturing operations, and other potentially hazardous industrial environments, our BRMs provide protected workspace for personnel without unnecessarily separating project teams from critical site operations.

Choose from a range of building sizes and standard layouts for offices, meeting areas, break rooms, control functions, and project support spaces. Hunter Onsite can also provide multi-unit and specialty configurations when a project requires additional capacity or a workspace designed around specific site conditions.

Blast-Resistant Modules for a Range of Site Needs

Hunter Onsite offers a broad selection of blast-resistant modules for industrial projects throughout Maine. From individual workspaces to connected modular complexes, BRMs can be selected and configured around workforce size, available site space, intended use, and project duration. Standard and specialty options provide flexibility for turnarounds, maintenance programs, capital projects, facility expansions, and ongoing operations.

Standard BRM Options

✓ Single Modules: 20-foot and 40-foot units for offices, break rooms, meeting spaces, and daily operations

✓ Multi-Unit Complexes: Connected modules for larger teams, shared workspaces, and extended projects

Specialized Solutions

✓ Specialty BRMs: Purpose-built options for permit offices, tool rooms, restrooms, and other project functions

✓ Custom Configurations: Flexible layouts and features designed around specific operational and site requirements

Easy roll-off delivery is available for most units, helping simplify placement without the need for a crane.

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.
