RP 752: Management of Hazards Associated With Location of Process Plant Buildings

Provides guidance for managing the risk from explosions, fires and toxic material releases to on-site personnel located in new and existing buildings intended for occupancy. This RP was developed for use at refineries, petrochemical and chemical operations, natural gas liquids extraction plants, natural gas liquefaction plants, and other onshore facilities covered by the OSHA Process Safety Management of Highly Hazardous Chemicals, 29 CFR 1910.119.

Buildings covered by this RP are rigid structures intended for permanent use in fixed locations. Tents, fabric enclosures and other soft-sided structures are outside the scope of this document.

Significant research and development of technology pertinent to building sitting evaluations has been performed since the publication of the previous editions of RP 752. Examples of updated technology include prediction of blast damage to buildings, determination of occupant vulnerabilities, and estimates of event frequencies. Prior versions of RP 752 and the technical data included in them should not be used for building sitting evaluations. This edition of RP 752 does not cover portable buildings. Portable buildings are now covered by RP 753.

RP 753 - Management of Hazards Associated With Location of Process Plant Portable Buildingss

Provides guidance for reducing the risk to personnel located in portable buildings from potential explosion, fire and toxic release hazards. While occupied permanent buildings (e.g. control rooms, operator shelters) located near covered process area are typically constructed to be blast and fire resistant, conventional portable buildings (i.e. light wood trailers) are typically not constructed to be blast and fire resistant. Past explosion accidents have demonstrated that occupants of conventional portable buildings are susceptible to injuries from structural failures, building collapse, and building debris and projectiles.

Guidance is provided based on the following principles:
  • Locate personnel away from covered process areas consistent with safe and effective operations.
  • Minimize the use of occupied portable buildings in close proximity to covered process areas.
  • Manage the occupancy of portable building especially during periods of increased risk including unit start up or planned shutdown operations.
  • Design, construct, install, and maintain occupied portable buildings to protect occupants against potential hazards.
  • Manage the use of portable buildings as an integral part of the design, construction and maintenance operation of a facility.
