1、Analysis, Design, Installation, and Testing of Safety Systems for Offshore Production FacilitiesAPI RECOMMENDED PRACTICE 14CEIGHTH EDITION, FEBRUARY 2017Special NotesAPI publications necessarily address problems of a general nature. With respect to particular circumstances, local,state, and federal

2、laws and regulations should be reviewed.Neither API nor any of APIs employees, subcontractors, consultants, committees, or other assignees make anywarranty or representation, either express or implied, with respect to the accuracy, completeness, or usefulness of theinformation contained herein, or a

3、ssume any liability or responsibility for any use, or the results of such use, of anyinformation or process disclosed in this publication. Neither API nor any of APIs employees, subcontractors,consultants, or other assignees represent that use of this publication would not infringe upon privately ow

4、ned rights.API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and properly train andequip their employees, and others exposed, concerning health and safety risks and precautions, nor undertaking theirobligations to comply with authorities having jurisdiction.

5、Information concerning safety and health risks and proper precautions with respect to particular materials andconditions should be obtained from the employer, the manufacturer or supplier of that aterial, or the material safetydatasheet.Work sites and equipment operations may differ. Users are solel

6、y responsible for assessing their specific equipmentand premises in determining the appropriateness of applying the provisions of this recommended practice. At alltimes users should employ sound business, scientific, engineering, and judgment safety when using thisrecommended practice.Classified are

7、as may vary depending on the location, conditions, equipment, and substances involved in any givensituation. Users of this recommended practice should consult with the appropriate authorities having jurisdiction.API publications may be used by anyone desiring to do so. Every effort has been made by

8、the Institute to ensure theaccuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, orguarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss ordamage resulting from its use or for

9、the violation of any authorities having jurisdiction with which this publication mayconflict.API publications are published to facilitate the broad availability of proven, sound engineering and operatingpractices. These publications are not intended to obviate the need for applying sound engineering

10、 judgmentregarding when and where these publications should be utilized. The formulation and publication of API publicationsis not intended in any way to inhibit anyone from using any other practices.Any manufacturer marking equipment or materials in conformance with the marking requirements of an A
