SCOPE: This document applies to laser proponents involved with the use of

18、 laser systems outdoors. It may be used in conjunction with AS4970, ARP5535, and ARP5572 and the ANSI Z136 series of laser safety standards.1.1 Purpose: The purpose of this document is to describe the issues, duties, and training of laser proponents specific to the use of lasers in navigable airspac

19、e. It is assumed that the laser proponent is well versed on the safe use of lasers indoors.1.2 Field of Application: AS4970 and ANSI Z136.6 provide guidance and information for the evaluation of laser operations in navigable airspace. Due to operational/mission requirements, some laser beams exceed

20、the maximum permissible exposure (MPE) limits or visual interference levels as defined in FAA Order 7400.2, ANSI Z136.1, and ANSI Z136.6. For this reason, mitigation and/or control measures may be required. 2. REFERENCES: 2.1 Applicable Documents: The following publications form a part of this docum

The terms defined

26、are therefore limited to those actually used in this manual.This list is not intended to constitute a dictionary of terms used in the laser field as a whole.AFTERIMAGE: An image that remains in the visual field after an exposure to a bright light.DAYTIME OPERATIONS: Any operations that occur between

27、 30 minutes before sunrise and 30 minutes after sunset are considered daytime operations. SAE ARP5293 - 8 - 2.3 (Continued): GLARE: Glare refers to temporary disruptions in vision without biological damage and is particularly disruptive under nighttime viewing conditions, especially when the eyes ar

28、e fully dark-adapted. Glare effects are diminished as the position of gaze shifts away from the light source, e.g., headlights from an oncoming car at night. Glare is most pronounced when it occurs in the central field of view and only occurs during illumination. FLASHBLINDNESS: Flashblindness is te

29、mporary loss of vision that persists after the bright light is terminated, e.g., from a camera flash. Flashblindness can last from several seconds to several minutes. LASER SAFETY OFFICER (LSO): One who has authority to monitor and enforce the control of laser hazards and to effect the knowledgeable

30、 evaluation and control of laser hazards. The LSO may, at times, delegate specific responsibilities to a deputy LSO or other responsible person. The LSO has ultimate responsibility for safe outdoor laser operations. Throughout the body of this document, it shall be understood that whenever duties or

31、 responsibilities of the LSO are specified, it will mean that the LSO either performs the stated task or ensures that the task is performed. LASER SAFETY SPECIALIST (LSS): An individual with the formal training or equivalent professional experience to correctly measure, calculate or determine laser

32、beam parameters and hazards and be familiar with the use of control measures to mitigate those hazards.MAXIMUM PERMISSIBLE EXPOSURE (MPE): The level of laser radiation to which a person may be exposed without hazardous effect or adverse biological changes in the eye or skin. NATIONAL AIRSPACE SYSTEM

33、 (NAS): A complex, highly interactive “system of systems“ involving large numbers of subsystems and components on the ground, and in the aircraft including facilities, equipment, and computer hardware and software as well as the people which enables hundreds of thousands of users to fly safely every

34、 day. NAVIGABLE AIRSPACE: For the purpose of this document, navigable airspace is that airspace that can contain aircraft. Navigable airspace is defined as airspace that is 500 feet from any structure in semi-populated areas. In heavily populated areas, aircraft are required to allow more distances

35、from structures. Near airports or heliports, navigable airspace extends to the runway. Helicopter operations may require additional considerations, since they are often flying below 500 feet. NIGHTTIME OPERATIONS: Any operations that occur between 30 minutes after sunset and 30 minutes before sunris

36、e are considered nighttime operations. SAE ARP5293 - 9 - 2.3 (Continued): NOMINAL HAZARD ZONE (NHZ): The NHZ describes the space within which the level of the direct, reflected, or scattered radiation during operation exceeds the applicable MPE.Exposure levels beyond the boundary of the NHZ are belo

37、w the applicable MPE level. NOMINAL OCULAR HAZARD DISTANCE (NOHD): The distance along the axis of the laser beam beyond which the appropriate MPE is not exceeded. SAFETY OBSERVER: One who has been tasked with observing the airspace through which a laser beam is being propagated to ensure that the be

38、am does not illuminate any individual or object that could be injured, impaired, or damaged as a result of such an exposure. The observer must be trained and have the ability to immediately terminate the laser beam. 3. BACKGROUND: The management of a facility using class 3b or 4 lasers must designat

39、e a laser safety officer (LSO), and must document and ensure that the LSO is appropriately trained. The LSO is ultimately responsible for safe outdoor laser operations. The LSO ensures that the use of lasers complies with FAA Order 7400.2, ANSI Z136.6, and other site-specific requirements (Federal,

40、State, Military, Organizational, etc.).The LSOs responsibilities include, but are not limited to, the following: Establishing an NHZ and NOHD Administering a medical surveillance program Filing applicable laser safety reports and forms with appropriate authorities Approving standard operating proced

41、ures Avoiding unnecessary or duplicate controls Selecting alternate controls Conducting periodic facility and equipment audits Maintaining records log for all outdoor laser operations Evaluating outdoor conditions to ensure laser propagation will not cause any hazards Training of personnel (laser op

42、erators, laser safety observers, and deputy LSOs) SAE ARP5293 - 10 - 3. (Continued): The LSO or designated representative should evaluate hazards in relation to operations to be performed. Evaluation of all lasers for outdoor propagation that have the potential to adversely affect aircraft operation

43、s in navigable airspace is strongly recommended. Worst-case scenarios must be evaluated to ensure safety of personnel (e.g., pilots, laser operators, and safety observers). Both diffuse and specular reflections should be considered in the hazard evaluation. Outdoor propagation of lasers should not b

44、e conducted until all forms have been submitted and clearances have been obtained. 4. TRAINING REQUIREMENTS FOR LASER SAFETY PERSONNEL USING LASERS OUTDOORS:The use of lasers outdoors poses many unique training needs for laser safety personnel.This training may be in the form of a formal course or m

45、ay be administered through specific standard operating procedures (SOPs) and literature supplied by the LSO. A proposed syllabus for laser safety training can be found in Appendix A.4.1 Laser Safety Officer: In order to accomplish their duties, the LSO must be trained or have access to someone who h

46、as been trained to a level appropriate to allow them to perform their duties. The following training topics are suggested for an LSO. Organizational laser safety policy Hazards, control measures, evaluation procedures, and medical surveillance requirements unique for the use of lasers outdoors Appli

47、cable standards and regulations (federal, state, and/or local) Airspace and aircraft considerations Government notification/coordination requirements Laser safety specialist (LSS) services Incident investigation and reporting Preparing SOPs and training instructions for laser users Record keeping of

48、 laser firings SAE ARP5293 - 11 - 4.2 Authorized Laser Operator/Worker: Laser operators shall receive training commensurate with the specific lasers with which they will be associated. Operators of Class 3b and Class 4 lasers shall receive specialized training for the lasers that they will operate.

49、The following training topics are in addition to the training outlined in ANSI Z136.1: Specific laser control measures Applicable SOPs (including emergency contingency procedures) Environments and conditions in which lasers may or may not be used Communication requirements Applicable standards and regulations (federal, state, and/or local) 4.3 Laser Safety Observer: For some laser systems, the safety observer may be the only practical control mechanism. For lasers that are operated for long periods of time and/or that
