Significance and Use3.1 The overall purpose of standards is to document andcommunicate best practices in the successful and consistentapplication of 3D imaging technolog
8、y. When executed effec-tively, this leads to an enhanced project performance. Thispractice offers a guideline for safe field operational proceduresused in the application of 3D imaging technology.3.2 ApplicabilityAs 3D imaging technology is appliedacross an ever increasing area of application, a set
9、 of uniformstandards for their safe application is necessary. This bestpractice shall serve as a guideline to both operator and end userensuring that necessary and reasonable precautions have beentaken to ensure the safe application of 3D imaging technology.4. End-User/Operator Responsibilities4.1 S
10、afe operation of 3D imaging equipment is the respon-sibility of both the end user and operator. The end user isidentified as that party using the 3D imaging system deliver-able to meet certain project requirements. To the greatest extentpossible, the end user shall ensure that safety practices arebe
11、ing followed.4.2 3D imaging system operators, identified as the partyoperating the 3D imaging system, bear the primary responsi-bility for its safe application. They should be sufficientlytrained in the safe and correct methods of the 3D imagingtechnology operation. In addition to those practices sp
12、ecific tothe technology, the operators shall be aware of site-specificsafety requirements and practices and ensure that these arebeing followed consistently.4.3 Safety Plan:1This practice is under the jurisdiction ofASTM Committee E57 on 3D ImagingSystems and is the direct responsibility of Subcommi

15、shohocken, PA 19428-2959, United States.4.3.1 Given the mutual responsibility for safety by the enduser and the operator, a written safety plan designed for aspecific 3D imaging project is strongly recommended. Devel-opment of such a plan should be the mutual responsibility ofboth the end user and t
16、he operator with each contributing theirrespective knowledge, training, and experience. Any safetyplan should encompass practices designed to ensure the safeapplication of the 3D imaging system while meeting the safetyrequirements relevant to a specific site.4.3.2 The safety plan establishes a commo
17、n understandingand awareness of safety by both the end user and the operator.Typically, a safety plan should address, but is not limited to:4.3.2.1 Safe application of 3D imaging system componentswithin the context of government regulations or industryspecific regulations, or both. Typically, such r
18、egulations focuson the light-emitting components of the imaging system. Thesafety plan should include a description of and procedurestaken to ensure that the system operation will conform withsite-established safety protocols and, at a minimum, regula-tions such as those of the Occupational Health a
19、nd SafetyAdministration (OSHA) (see standards in Section 1.3.3). Issuessuch as laser emission impact on existing operations andpersonnel with respect to eye safety, possible distraction byvisible beams, and so forth, with a corresponding plan address-ing area control would become a key component of
20、the dailyjob hazard analysis.4.3.2.2 The safety plan shall include site-specific safetyrules, regulations, disruption of operation notices, and so forth,covering various operational scenarios. Such scenarios typi-cally include transportation of equipment, placement of refer-ence targets, use of ladd
21、ers or scaffolding, or both, use of anyelevated system platform, use of personal protection equip-ment, and so forth.4.3.2.3 Site-specific hazards such as confined spaces, ve-hicle or pedestrian traffic, or both, explosion-endangered areas,and so forth and the safe application of equipment within th
22、econstraints of said hazards should be addressed in the safetyplan.4.4 Operator Training:4.4.1 Operator training is a key component of any safetyplan. In applying 3D imaging technology to a specific project,operators should be trained in three specific areas.4.4.1.1 The first is the safe application
23、 of the 3D imagingequipment itself. Specifically, the operator shall demonstratefamiliarity with safety requirements of each component of the3D imaging system.4.4.1.2 Secondly, the operator bears the primary responsi-bility for the awareness of the general safety requirements ofthe 3D imaging system
24、. For example, should the system emitlaser light, the operator should be familiar with the system laserclassification and those safety requirements imposed by suchagencies as the Food and Drug Administration (FDA), Centerfor Devices and Radiological Health (CDRH), OSHA, andothers as well as any spec
25、ific state or local regulations.4.4.1.3 Finally, the operator should be aware of any hazardsthat are present at each job site and understand the relevant safeoperating procedures specific to that site.4.4.2 The end user may require verification that suchtraining has occurred.4.5 Operator AwarenessA
26、safety plan specific to the siteis the recommended practice for ensuring safe operation to thegreatest extent possible. The safety plan should possess amechanism promoting and verifying operator awareness of thesafety plan and the requirements stated therein and end userawareness that such procedure
27、s are being followed. This mayinclude a daily checklist designed to ensure safety measures arefollowed in accordance with the safety plan throughout theproject. Such a checklist should be designed to reinforceadherence to the safety plan and include areas for incidentreports and general comments.5.
28、Safe Application of Laser Technology5.1 3D imaging systems are comprised of several compo-nents typically including a power supply, processing computer,laser imaging detection and ranging (LiDAR) scanner, andoften, a camera. A transmitting laser is often a key componentin a 3D imaging system and is
29、often the principal safetyconcern when using a 3D imaging system.5.2 The manufacturer of 3D imaging equipment using lasertechnology is responsible for its appropriate laser classifica-tion.5.3 The operator is responsible for applying the technologysafely per the requirements of the laser classificat
30、ion as definedby applicable government agencies such as CDRH, OSHA, andso forth.5.4 Laser Hazard Classification:5.4.1 All laser systems manufactured or purchased by acompany are classified with respect to their performancecharacteristics and are labeled accordingly. Different levels ofsafety precaut
31、ions are applicable to each classification. For thisreason, the safe use of 3D imaging systems begins withunderstanding the laser hazard classification of the instrumentand appropriate safety measures required. This knowledgefacilitates development of the project safety plan and imple-mentation of c
32、orrect precautionary measures while using the3D imaging system.5.4.2 The end user and operator should be familiar with theapplicable standards regarding laser classification and thecorresponding safeguards required for operation. See the Bib-liography for further information.5.5 Applicable Local Law
33、sIn addition to law and regula-tions issued by government agencies and regulating bodies,there often exist laws or regulations, or both, issued by state orlocal agencies regarding the emission of laser light. Theoperator should be aware of any relevant local law(s) orregulations, or both, and their
34、relevance to the application ofthe operators specific 3D imaging system.6. Keywords6.1 laser; safety plan; scan; 3D imaging technologyE2641 092APPENDIXESX1.
