FAQs

Want to learn more about HUNTER? Below you’ll find some frequently asked questions to help you understand Hunter from the outside in. Are your buildings Class I Division 2 compliant? Does my building need to have pressurization? How large or small of a structure can HUNTER build? What is a damage/response level? How can a HUNTER building help me become API 752/753 compliant? How is a HUNTER building transported to my location? Once a building is delivered to my site, how do I unload it? Can my building have windows? Can your buildings be used to replace permanent structures such as control rooms? How long will it take to receive my HUNTER building? Why do I need a blast-resistant modular building? Are your buildings Class I Division 2 compliant? Class I Division 2 defines the level of safety required for equipment installed in hazardous locations. All standard HUNTER buildings are externally Class I Division 2 compliant. Back to top Does my building need to have pressurization? Per NFPA 496 latest revision, any Class I, II, or III location requires pressurization if general purpose equipment will be utilized. By not following this practice, a potential spark from the general purpose equipment could lead to an occurrence. Other instances that may require pressurization can be driven by site specific requirements. Back to top How large or small of a structure can HUNTER build? Our standard size is 12′ x 40′; however, HUNTER can design structures as small as a guard shack at 100 square feet up to a large multi-module complex exceeding 12,000 square feet. Back to top What is a damage/response level? The American Society of Civil Engineers (ASCE) has established the following ratings to help estimate the cost of repairs and reuse after a blast-resistant building has been subjected to a blast. The three response ranges for blast overpressures are: High Response: Key components may have lost structural integrity; building may collapse due to environmental conditions (i.e. wind, rain, snow); and total cost of repairs approaches replacement cost of building. Medium Response: Significant repairs needed from widespread building damage; building cannot be used until repaired; and cost of repairs is likely significant. Low Response: Minor repairs from damage needed but building can be used; and cost of repairs may be moderate. In all instances of response, the individuals inside of the building are protected! Back to top How can a HUNTER building help me become API 752/753 compliant? RP 752/753 guidelines require that buildings situated in any process area must be certified to withstand the blast overpressures for that given area. A HUNTER building is appropriately rated to meet zone requirements for API 752/753. Back to top How is a HUNTER building transported to my location? HUNTER buildings are manufactured at one of our three manufacturing facilities. Depending on where the building is being shipped, we can determine which facility to utilize for manufacture. This also ensures that the customer doesn’t have to pay more for shipping than needed. Buildings are usually shipped by truck to your location.                            . Back to top Once a building is delivered to my site, how do I unload it? HUNTER buildings are constructed with lifting points at each building corner for easy lifting by mobile cranes. HUNTER Site Services can provide full service with unloading, setup and finish out of the buildings as needed by the customer. Back to top Can my building have windows? Yes, our blast windows are 30″ x 36″ with fixed panes. Windows can be combined to provide a larger viewing area. We also offer a window for doors. Back to top Can your buildings be used to replace permanent structures such as control rooms? Yes, our buildings can be used for permanent applications including control rooms, operator structures, zone shops, offices, labs and more. Back to top How long will it take to receive my HUNTER building? For a standard building design, we can typically deliver a building within four weeks of order. For custom designs, the delivery times can vary based on design complexity. However, a custom building could be delivered within 90 days of approval of drawings. Back to top Why do I need a blast-resistant modular building? If you have an existing project, a HUNTER building can help your current work area meet blast standards in a quick and cost-effective manner. If you have a new project, a HUNTER blast-resistant building offers a more efficient solution to meeting blast-resistance standards. Unlike other modular buildings, a HUNTER building can be kept in the blast zone—increasing worker productivity and more. Back to top
