4. When training with live grenades in a tire house, trench line, or like environment and a dud grenade is experienced, all activities within the structure or danger area will stop. Personnel will remain within a safe area for a minimum of 5 minutes and then evacuate the structure or area until EOD clears the dud. 5. Range cadre and commanders are cautioned that multiple employment of grenades in a training scenario significantly increases the difficulty of determining the actual number of grenades that detonated. Dud grenades may be activated by subsequent training, generating an unplanned detonation. 6. Simultaneous employment of multiple fragmentation grenades into a single impact point is prohibited, as a live grenade could be propelled into the "safe area" by the detonation of another grenade (Marine Corps). 7. The use of hand grenades during live-fire exercises shall conform to the provisions provided by chapter 17. c. Firing conditions for chemical and incendiary hand grenades. (1) Chemical grenades will not be held in the hand after the safety lever is released. The incendiary hand grenade may be taped or tied in place if the incendiary effect is desired at a specified location. In this case, safety pins will not be pulled from the grenade until the desired time of functioning. Remote safety pin removal is preferred. (2) Burning type grenades (riot control, smoke, illumination, and incendiary) are ignited by pulling the safety pin and releasing the safety lever. After the safety pin has been pulled, the safety lever will not be released until the grenade exits the throwing hand. Once the safety lever is released, there is no way to stop the grenade from functioning. When the burning type grenade is fired in place, the firer will keep their face turned away from the grenade. After releasing the safety lever, the firer will quickly move at least 10 m away to avoid contact with incendiary particles and fumes emitted during burning. (3) Personnel will be instructed on the proper method of holding the M25 bursting type, riot control grenade before commencing training exercises. The arming sleeve will remain depressed until the grenade is thrown. M25 grenades will not be thrown closer than 25 m to unprotected personnel. (4) Burning type grenades burn oxygen. Standard protective masks filter particles but will not supply oxygen. Therefore, burning grenades shall not be used in enclosed or confined spaces (such as occupied tunnels) or in other confined spaces into which personnel will enter until those spaces are ventilated. Specific fuse burning delay times and functioning characteristics are in TM 9–1330–200–12 and TM 43–0001–29. (5) Burning type 0-chlorobenzyl denemalononitrite (CS) grenades will not be fired closer than 10 m to other personnel or 50 m to spectators upwind. (6) Hexachloroethane (HC) smoke grenade restrictions are the same as those for HC smoke pots. These grenades will ignite combustible materials and cause burns. A separation distance of at least 10 m should be maintained from burning grenades. Personnel will wear protective respirators or masks before exposure to any concentration of smoke produced by HC smoke grenades. (See chap 13 for detailed information concerning smoke hazards.) (7) Burning particles of white phosphorous (WP) are frequently projected from the M15 and M34 grenades to a distance of 40 m from the bursting point. Therefore, M15 and M34 WP grenades should be thrown only on standard live grenade ranges during training as prescribed in FM 3–23.30. Trainers should consider use of protective cover when using the M15 and M34. White phosphorous particles cause serious, painful, slow-healing burns. Refer to FM 4–25.11 for appropriate first-aid measures. (8) Direct viewing of thermite grenades will not be conducted due to the high potential of permanent eye damage. d. M84 Stun Grenade. All personnel within 1.52 m (5 ft) will wear single hearing protection if employing 2 rounds per day. All personnel within this distance will wear double hearing protection if employing 3 to 41 rounds per day. e. Surface danger zones. (1) Surface danger zone requirements for hand grenades are provided in figure 5–1. (2) Planning guidance for hand grenade ranges is in TC 25–8. 47 DA PAM 385–63 • 16 April 2014
