Which document provides guidance for the safe use of military lasers and laser systems on DoD rangs?E - correct answer MIL-HDBK-828C What is the collective documents that governs range safety for the US Army and US Marine Corps - correct answer AR 385-63/MCO 3570.1D As an LRSO, you will ensure a clear line of sight exists between the laser system and the target prior to starting a laser operation. What type of control measure does this represent? - correct answer Engineering control Which of the following is NOT a factor to be considered when placing targets for laser employment? - correct answer The laser hazard can be contained outside of the range boundaries. You are supervising a range laser operation involving laser-guided weapons. The munitions detonations are causing smoke and dust to partially obscure the targets. As LRSO, what action should you take? - correct answer Hold training until the smoke and dust clear. You are supervising a laser operation and observe reflection of the laser beyond the targets. You call a cease fire. What could be the cause of the reflection? - correct answer Targets may be smaller than the laser spot size and overspill is occurring. You are inspecting a range prior to the start of a range laser operation. You observe standing water within the LSDZ that pooled there last night during a rain storm. As a LRSO what action do you take? - correct answer Call Range Control for guidance What is the minimum rank that one can serve in a capacity as an LRSO? - correct answer E-5 Which of the following is NOT a responsibility of an LRSO as part of conducting range laser safety inspection? - correct answer Post laser warning signs in accordance with DA PAM 385-63. During a laser operation, as an LRSO you are responsible for ensuring energized lasers are oriented correctly. Hoe should lasers be oriented? - correct answer Lasers are pointed towards the targets. Which class of laser system is considered safe if handled carefully, with restricted viewing? - correct answer Class 3R What does the "M" designator indicate when associated with a class of laser system? (Example: Class 1M) - correct answer Hazardous when viewed with magnifying optics What is the principle hazard associated with exposure to laser radiation? - correct answer Eye damage What type of laser application uses a bright light to cause visual field obscuration in a targeted individuals and is intended to primarily a warning device? - correct answer Ocular Interruption Lasers are used for a variety of military applications. What type of laser application uses a laser primarily as a warning device? - correct answer Ocular Interruption Which of the following could produce a specular reflection from a laser? - correct answer Calm water What type of laser application uses a laser to point out the location of a target? - correct answer Laser marking Which of the following surfaces most likely would produce a diffuse reflection from a laser? - correct answer Dry foliage A diffuse reflection differs from a specular reflection. Which o the following statements is NOT true regarding diffuse reflection? - correct answer A diffuse reflection produces a concentrated beam that allows the seeker to lock on. What class of laser system is hazardous to personnel viewing the source directly or by specular reflection, but do not present a diffuse reflection or skin hazard? - correct answer Class 3B What class of laser system can present a potential diffuse reflection hazard and a skin or fire hazard? - correct answer Class 4 You are serving as LRSO for a range laser operation. You have certain duties pertaining to the LSDZ. Which of the following actions must you ensure? - correct answer LEP is worn inside the LSDZ. True or False? You will never be assigned as an RSO and LRSO during the same operation. - correct answer False Which of the following items that may be found in a target area can produce specular reflections and must be removed prior to a laser operation? Select all that apply... - correct answer Still Water, Window, Chrome-plated Metal You are serving as LRSO to supervise a range laser operation. What types of incidents would require you to cease laser operations? - correct answer Specular reflection present Smoke and dust obscure targets Traffic enters the LSDZ Poor tracking is observed What is the optimal attack path for an aircraft when employing laser-guided air-to-ground weapons? - correct answer The optimal attack zone is inside a 120-degree cone whose apex is at the target and extends to 60 degrees on either side of the target-to-laser designator line and is outside the 20 degree exclusion zone, both laterally and vertically. You are looking to reduce risks to personnel, and you are looking at the different road blocks and gates around the range. Which type of control measure does this fall in? - correct answer Administrative control measures You are supervising a range laser operation that calls for employment of rifles with the AN/PEQ-15 Advanced Target Pointer Illuminator Aiming Light (ATPIAL). The unit shows up with the AN/PEQ-16A Mini-Integrated Pointer Illuminator Module (MIPIM), which personnel tell you is "the same thing". Are the laser systems brought to the range authorized? - correct answer No. Even though they fall into the same laser classification, the range request identified the ATPIAL. You are preparing a three-part safety/pre-mission brief for an upcoming training exercise. For part one, under the category of Laser TM, which reference will you use to gather the information you need? - correct answer Laser systems information For part three, under the category of DA PAM 385-63, which reference will you use to gather the information you need? - correct answer Laser safety considerations For part two, under the category of Range Request/Range SOP, which references will you use to gather the information you need? - correct answer Mission profile, authorized targets, PPE What is the definition of a Laser Surface Danger Zone (LSDZ)? - correct answer The minimum land and air requirement, to include terrain mitigation, needed to safely employ a given laser.
