handled. Follow safety instructions in equipment instruction manuals regarding the use of the CO2 gas and its containers. 15–11. Safety requirements for firing aerial pyrotechnics (Marine Corps only) a. Personnel participating in exercises that include the firing of aerial pyrotechnics such as Smokey Sams or Smokey Guns will wear PPE Level 1 and other protective equipment required by SOPs. b. Inspect Smokey Sam rockets prior to use and report all rockets that appear to have moisture damage. Damaged rockets will not be fired. c. When firing these pyrotechnics, anyone may stop the firing sequence if it is not safe to fire, or if the dispensing aircraft is within 610 m (2,000 ft) as prescribed in NAVAIR TM 11–75–63. 15–12. Training conducted in explosive entry techniques a. Explosive entry techniques are used in special missions where assault personnel require immediate access to the target. To train for this mission, individuals must be closer to the detonation than is authorized elsewhere in this chapter. Because of the unique character and requirements of this training, the following special safety guidelines are established to support this training. (1) Stand-off distance for personnel will be determined using the formula D (ft) =K x W 1/3 where D=distance, K=a constant (the K factor for explosive entry techniques is set at 18) and the W 1/3 =cube root of weight of the explosives in pounds. This is the limit at which the possibility of eardrum damage is less than 1 percent. This stand-off distance is related to blast pressure and does not reflect fragmentation damage. When a barrier is used, the safe overpressure standoff distance may be divided by 2. (2) Fragmentation standoff will equal the blast standoff when a protective barrier is provided between the explosive and the personnel. This barrier may be in the form of wood, cement, metal, or a ballistic blanket barrier. The barrier must be able to absorb all fragmentation. (3) All personnel within the fragmentation distance of a detonation will wear appropriate protective gear. For the Army, all personnel will wear approved protective helmets, IBA and single hearing protection. For the Marine Corps, PPE Level 2. Eye protection will be worn. Personnel conducting the detonation will also wear fire-resistant hoods, coveralls, and gloves. Clothing with short sleeves is not authorized when conducting this training. b. For the Marine Corps, SDZs for ranges dedicated to the conduct of explosives entry techniques will be set and approved by CG, MCCDC (C465). 15–13. M2 and M4A1 Selectable Lightweight Attack Munition and the M3 Demolition Attack Munition a. The M2 and M4A1 Selectable Lightweight Attack Munition (SLAM) and the M3 Demolition Attack Munition (DAM) is a multipurpose munition with anti-disturbance and anti-tamper features, designed to be readily portable and hand-emplaced against lightly armored targets. The primary lethal mechanism is an explosively formed penetrator (EFP). The hazardous fragment distance of the EFP is highly dependent on the orientation of the munition and line of fire. b. The M2 self-neutralizes and the M4A1 self-destructs. Do not attempt to change the setting after the activation lever is pulled. Once the activation lever is pulled, the time/mode on the selector switch is entered into memory and cannot be changed. Physically moving the selector switch after the activation lever is pulled appears to change the setting, but the original setting will remain in the memory. c. The M3 DAM has one mode of operation, which is by command detonation. The DAM contains explosive but has no battery, electronics, or associated parts including sheer pin activation lever, or passive sensor. Manual warhead initiation is provided using M6 or M7 blasting caps with M1A4 priming adapter. d. All personnel within 240 m (792 ft) of a detonating SLAM/DAM are required to wear single hearing protection. e. SDZ for the M2 and M4A1 SLAM and M3 DAM is in figure 15–9. Vertical hazard distance for the EFP is 2,969 m. Distance X is 236 m, except in the direction of the EFP, in which case it is 3,911 m 20 degrees on either side of the anticipated line of travel of the EFP. Personnel outside that 40 degrees cone protected by 3 in of armor may be as close as 100 m to the detonation point. 198 DA PAM 385–63 • 16 April 2014
