2、ecial NotesAPI publications necessarily address problems of a general nature. With respect to particular circumstances, local, state, and federal laws and regulations should be reviewed.Neither API nor any of APIs employees, subcontractors, consultants, committees, or other assignees make any warran

Sound business, scientif
5、ic, engineering, and safety judgment should be used in employing the information contained herein. API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and properly train and equip their employees, and others exposed, concerning health and safety risks and prec
6、autions, nor undertaking their obligations to comply with authorities having jurisdiction.Information concerning safety and health risks and proper precautions with respect to particular materials and conditions should be obtained from the employer, the manufacturer or supplier of that material, or
7、the material safety datasheet.Where applicable, authorities having jurisdiction should be consulted.Work sites and equipment operations may differ. Users are solely responsible for assessing their specific equipment and premises in determining the appropriateness of applying the RP. At all times use
8、rs should employ sound business, scientific, engineering, and judgment safety when using this RP.API publications may be used by anyone desiring to do so.

14、ferences documents concerning technical aspects of building siting evaluation including hazard identification, consequence modeling, structural analysis, and risk. Among the hazards that potentially could affect building occupants are explosion, fire, and toxic material releases.This third edition o
15、f API RP 752:2009 supersedes all previous editions, including the technical data provided in those documents. Significant research and development of technology pertinent to building siting evaluations has been performed since the publication of the previous editions of API RP 752. Examples of updat
16、ed technology include prediction of blast damage to buildings, determination of occupant vulnerabilities, and estimates of event frequencies. Prior versions of API RP 752 and the technical data included in them should not be used for building siting evaluations. The second edition of API RP 752:2003
17、 covered all building types both permanent and portable. This third edition of API RP 752:2009 does not cover portable buildings. Portable buildings are now covered by API RP 753:2007. It is recognized, however, that portable buildings specifically designed for significant blast load represent a pot
18、ential area of overlap between API RP 753 and API RP 752. In accordance with 1.3 of this document:“Buildings described in API RP 753, Management of Hazards Associated with Location of Process Plant Portable Buildings, First Edition, June 2007, as portable buildings specifically designed to resist si
19、gnificant blast loads and intended for permanent use in a fixed location are covered in this document (API RP 752). All other portable buildings are covered by API RP 753.”Nothing contained in any API publication is to be construed as granting any right, by implication or otherwise, for the manufact
20、ure, sale, or use of any method, apparatus, or product covered by letters patent. Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent.Shall: As used in an RP, “shall” denotes a minimum requirement in order to confo
21、rm to the RP.Should: As used in an RP, “should” denotes a recommendation or that which is advised but not required in order to conform to the RP. This document was produced under API standardization procedures that ensure appropriate notification and participation in the developmental process and is
22、 designated as an API standard.

A one-time extension of up to
24、two years may be added to this review cycle. Status of the publication can be ascertained from the API Standards Department, telephone (202) 682-8000. A catalog of API publications and materials is published annually by API, 1220 L Street, NW, Washington, DC 20005.Suggested revisions are invited and
