Study Notes
Military Laser Safety Guidelines
- MIL-HDBK-828C provides guidance for safe use of military lasers and laser systems on Department of Defense ranges.
- AR 385-63/MCO 3570.1D collectively governs range safety for the U.S. Army and U.S. Marine Corps.
Laser Safety Responsibilities
- An LRSO (Laser Range Safety Officer) must ensure a clear line of sight exists between the laser system and the target before operations, representing an engineering control.
- As LRSO, halt training operations if smoke or dust obscures the targets due to munitions detonations.
Laser Operation Procedures
- In case of laser reflection beyond targets, a ceasefire should be called as it may indicate target size is smaller than the laser spot size, resulting in overspill.
- If standing water is observed in the LSDZ (Laser Safety Danger Zone), the LRSO should contact Range Control for guidance.
Rank and Responsibilities
- The minimum rank for serving as an LRSO is E-5.
- Posting laser warning signs as per DA PAM 385-63 is not a responsibility of an LRSO during range safety inspections.
Laser Orientation and Classifications
- Energized lasers must be oriented correctly toward the targets during operations.
- Class 3R laser systems are considered safe with restricted viewing, while Class 1M indicates hazards when viewed with magnifying optics.
Hazards and Applications of Lasers
- Eye damage is the principal hazard associated with exposure to laser radiation.
- Ocular interruption is a laser application using bright light to obscure visual fields, primarily serving as a warning device.
Reflection Types and Safety
- Specular reflections can occur from calm water, windows, and chrome-plated metal and should be removed from target areas before operations.
- Diffuse reflections happen from surfaces like dry foliage and differ from specular reflections, which produce concentrated beams.
Laser Classifications and Risks
- Class 3B lasers are hazardous to personnel if viewed directly or by specular reflection but pose no diffuse reflection or skin hazards.
- Class 4 lasers present potential diffuse reflection hazards and can cause skin or fire hazards.
Personal Protective Equipment and Operations
- LRSOs must ensure that Laser Eye Protection (LEP) is worn inside the LSDZ.
- An LRSO may be assigned as both RSO (Range Safety Officer) and LRSO during an operation, contrary to common assumptions about assignments.
Situations Requiring Cease of Operations
- Laser operations must cease if:
- Specular reflections are detected.
- Smoke or dust obscures targets.
- Unauthorized traffic enters the LSDZ.
- Tracking is poor.
