13、2003.)This standard is a revision of American National Standard for Plastics Machinery -Extrusion Blow Molding Machines - Safety Requirements for Construction, Care, andUse, ANSI/SPI B151.15-2000. The standard was revised because:1) Some paragraphs required modification and some paragraphs were adde

14、dto conform more closely to changes in technology;2) Some paragraphs required modification for clarity and intent.The project on safety requirements for the manufacture, care, and use of extrusionblow molding machines was initiated under the auspices of the Extrusion Blow Mold-ing Section of the Mac

15、hinery Division, and the Safety Committee of the Molders Man-agement Division, of the Society of the Plastics Industry, Inc. (SPI).Both divisions of the SPI have long been concerned with operator safety on plasticsprocessing equipment. Accordingly, each section of the divisions has established astan

16、dards development committee charged with the task of establishing necessarystandards.A standard treating the manufacture, care, and use of extrusion molding machines iscomplicated by the wide variety and sizes of machines manufactured and in use, andby the virtually infinite combinations of parts be

17、ing produced, the production methodsused, and the operating conditions existing in industry today.The primary objective of this standard is to minimize hazards to personnel associatedwith machine activity by establishing requirements for the manufacture, care, anduse of these machines.To accomplish

18、this objective, the committee decided to approach the problem of ma-chine safety from two directions:1) Eliminating by design certain recognized hazards and establishing standardapproaches to design so that machines available from competitive manufacturerswill have similar operational characteristic

19、s;2) Safeguarding the machine to protect personnel from recognized hazards.To assist in the interpretation of these requirements, responsibilities have been as-signed to the manufacturer, the remanufacturer, the modifier, and the employer.Recognizing the impossibility of updating equipment and chang

20、ing operation meth-ods allied with existing machines immediately after approval date of this standard, a3-year period has been provided to employers for updating machines.Recognizing the impossibility of immediate updating of design and manufacturingmethods, Clauses 5 and 8 shall become effective on

21、e year after the approval date ofthis standard.Suggestions for improvement of this standard will be welcome. They should be sentto the Society of the Plastics Industry, Inc, 1801 K Street, NW, Suite 600K, Washing-ton, DC 20006-1301.Consensus for this standard was achieved by use of the Canvass Metho
