A History of Improving Your Protection

Modular Blast-Resistant Buildings

1992 OSHA begins enforcement of the “Process Safety Management of Highly Hazardous Chemicals” standard, with the expressed intent of reducing the number of hazardous incidents at these facilities. As an appendix to the rule, a compliance guide is produced discouraging the use of portable buildings within plant process areas. At the time, wood-framed construction (such as a traditional trailer) was popular because of the ease in placing the structures (and workers) near the work area and later relocating them, typically for temporary projects. Due to OSHA’s stance and the specific incidents of wood-framed trailer collapse and the resulting injury/death of occupants, API and CMA jointly develop API Recommended Practice 752 (API RP 752). The guidelines identified the types of buildings commonly found in process settings and provided a means of assessing building occupants risk when exposed to high levels of “overpressure” resulting from an explosion. Further, building modifications or complete replacements were recommended with “a new building using explosion-resistant design.” 1999 As a result of these practices, HUNTER is conceived with a singular goal of designing and marketing a superior building to replace wood-frame constructions altogether. The use of “modular buildings” was already well established on offshore platforms for long-term employee housing, but the concept was new to the refining and petrochemical industries. We knew our buildings would require unprecedented, custom design to meet intense safety and “blast” specifications. Such a quality product would be arguably more expensive than wood-frame trailers to rent or purchase, but we believed that the value of having employees safe and in close proximity to the work area would far surpass the additional costs to the refining and petrochemical companies. Today, HUNTER continues to invest substantially in design and engineering research, forever seeking to improve our buildings. We also continue to retain the services of ABS Consulting, a widely-recognized and respected blast specialist and risk management firm to evaluate any changes or improvements before we include them in any of our buildings. HUNTER’s modular blast-resistant buildings are also now used for protection in different types of situations including forced entry, ballistics, physical threats, harsh environments, and natural disasters.
