API RP 753 PDF

This recommended practice (RP) recommended practice (RP) provides guidance for managing the risks from process-related explosion, fire, and toxic material release hazards to personnel located in on-site portable buildings.
The document is based on the API 752 guidance for siting evaluations and the referenced documents concerning its technical aspects. For guidance on the evaluation of each hazard type, the reader should reference API 752. This document provides clarifications and alterations where necessary to address portable buildings.

This RP covers:

— new and existing light wood trailers;

— new and existing portable buildings (other than light wood trailers) intended for perpetual use (intended to be used for the life of the building or life of the process plant) in a specific, fixed location.

Annex B provides examples on the coverage of permanent and portable buildings/tents.

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, such as those covered by the Occupational Safety and Health Administration (OSHA) process safety management regulation, 29 CFR 1910.119.

Non-process-related hazards exist that could present risks to building occupants including, but not limited to, fires originating from within the building, structural collapse due to extreme weather/seismic events, and objects falling on or striking the building. These non-process-related hazards are addressed by building design standards and applicable building codes/regulations, and are not within the scope of this RP.
