The most important things to MBI’s customers are safety and security. While these are an absolute must, it is also imperative that these buildings meet the required building codes, as well as provide customers with the necessary compliance required by its industries regulatory agencies.
MBI’s protective building systems are specifically designed, engineered, and manufactured to allow our customers to be completely compliant with API RP 752/753. MBI also realizes that because of the safety and security nature of its products, and the fact that many of its customers use MBI products as a line of defense; all MBI buildings are also compliant with OSHA’s Mechanical Integrity requirements. Below is a summarization of each. These summaries are direct references to API’s RP 752/753, and are for your education only. Please refer directly to API RP 752 and API RP 753 for specific guidance in your decision making processes.
Wood-frame trailer or shack 1.0 Isolated buildings overturn. Roofs and walls collapse.
For more in-depth information on RP 752, please refer to API Recommended Practice 752 second edition, 2003.
Three zones for siting portable buildings based on external vapor cloud explosions, was established. These zones are defined by standoff distances as a function of congested volume.
For congested volumes less than 7,500 cubic ft, portable buildings intended for occupancy shall be located at a standoff distance greater than 330 ft or at a distance determined by performing a Detailed Analysis.
For congested volumes greater that 1,000,000 cubic ft a Detailed Analysis is required. This Detailed Analysis is required for any portable building in Zone 1 or Zone 2. Two methods of Detailed Analysis are Consequence Analysis and Quantitative Risk Analysis (QRA). Please refer to API RP 753 for more details on each.
Personal protection equipment (PPE) to be used by all occupants during the evacuation if required.
Please remember that this information is a summary of the original API RP 753, and has been provided for your education only. Please refer to API Recommended Practice 753 for full details and guidelines.
MBI is strongly focused on providing the safest products on the market. Along with its focus on safety, MBI focuses on providing fully compliant buildings to its customers. Taking into consideration that a large portion of the industry deems our products as critical safety equipment and lines of defense, we provide the required documentation for OSHA Mechanical Integrity. MBI provides a Manufacturer’s Data Report with all buildings. This one page document summarizing all the specifications of the building is fully supported by a comprehensive customer data package consisting of professionally stamped engineering structural drawing and calculations; all material traceability documentation, material tests and non-destructive test reports, MSDS sheets, etc.; and all fabrication certifications, including welding and construction process documentation.
With PSM Rule, 29 C.F.R. 1910.119, and its MI provision, 29 C.F.R. 1910.119(j), and its application to structures housing employees near hazardous process operations, it is interpreted that these structures must have MI-compliant blast resistant protection.
For process equipment, including structures housing employees near hazardous process operations, the PSM Rule requires that employers document the methods and materials of construction, including adequate engineering. The PSM Rule “contains requirements for preventing or minimizing the consequences of catastrophic releases of toxic, reactive, flammable, or explosive chemicals,” including “toxic, fire, or explosion hazards.” 29 C.F.R. § 1910.119. It requires that employers compile “written process safety information,” including “information pertaining to the equipment in the process.” Id. § 1910.119(d). Employers must include information on such aspects of equipment as: “[m]aterials of construction,” “[v]entilation system design,” “[d]esign codes and standards employed,” and “[s]afety systems.” Id. § 1910.119(d)(3)(i). In addition, employers “shall document that equipment complies with recognized and generally accepted good engineering practices.” Id. § 1910.119(d)(3)(ii).
On top of these requirements, for equipment that is “critical to process safety,” OSHA imposes even stricter rules under its MI provision. For such critical equipment, employers “shall establish and implement written procedures to maintain the on-going integrity of process equipment.” Id. § 1910.119(j)(2). They must inspect and test covered equipment, following recognized and generally accepted good engineering practices.” Id. § 1910.119(j)(4). Employers must document “each inspection and test” with specific, detailed information. Id. § 1910.119(j)(4)(iv). They must ensure that new equipment “as it is fabricated is suitable for the process application for which they will be used.” Id. § 1910.119(j)(6)(i). They must also “assure that equipment is installed properly and consistent with design specifications and the manufacturer’s instructions.” Id. § 1910.119(j)(6)(ii).
The Rule thus requires employers installing a building that houses workers near hazardous process equipment, such that the building is critical to process safety, to ensure that the building is blast resistant (i.e., “suitable” for the process application) and meets generally accepted good engineering practices (i.e., actually blast resistant as needed for such an installation), has documented manufacturing inspections and tests (such as tests of welding performed), and has suitable fabrication for installation near such a significant explosion, fire, or toxic release hazard (including actually featuring blast resistance and having documentation of such details as the grade and origin of steel and other components used).
The Agency believes that there is certain equipment, critical to process safety, that is common to all processes. This is the equipment specified in proposed paragraph (j)(1). It is the position of OSHA that at least the equipment specified in proposed paragraph (j)(1) must be subject to the requirements contained in paragraph (j). However, if an employer deems additional equipment to be critical to a particular process, that employer should consider that equipment to be covered by this paragraph and treat it accordingly.

Evans, Associate Director of Operational Safety and Risk Management at Union Carbide Corp.; March 23, 2000 to Ms. Lois Ferson, Manager of Standards Services at ISA; and July 11, 1994 to Mr. Joseph Schneider, Prof’l Dev. Chairman of the Cent. Fla. Section of the American Inst. of Chemical Engineers.
Moreover, the Appendix to the Rule indicates that PSM and MI requirements apply to “second line of defense” systems, which “control or mitigate hazardous chemicals once an unwanted release occurs.” The “primary and secondary lines of defense are what the mechanical integrity program needs to protect.” See 29 C.F.R. § 1910.119, App. C. Certainly, structures housing workers near hazardous process operations meet both of these definitions, as equipment “critical to process safety” and as a “second line of defense” that can mitigate releases after they occur, if the structures have adequate protection, such as MI-compliant blast resistance.
MBI provides Mechanical Integrity documentation on all buildings to ensure that both customers and their employees are protected from potentially catastrophic injury and liability.
