About Blast-Resistant Building Safety

A blast-resistant building needs to do more than provide workspace. Hunter Onsite BRBs are engineered for industrial environments where personnel may need to remain closer to active operations while maintaining an appropriate level of blast protection.

Many Hunter Onsite units are rated at 8 PSI with a medium response level, with other ratings available depending on the building and application. Each unit also includes practical interior features such as finished walls and ceilings, electrical service, communications provisions, and HVAC.

For projects requiring blast-resistant building rentals in California, this combination of protection and functionality helps create workspace that supports both site safety and workforce productivity.

Blast-Resistant Building FYI: Are blast-resistant buildings regulated?

No, there are no official global standards that cover blast-resistant modular buildings. The American Petroleum Institute (API) has provided recommended best practices that include design, construction, installation and maintenance:

API 752 - blast-resistant guidelines for structures intended for permanent use in fixed locations
API 753 - blast-resistant guidelines for temporary and portable structures
