Pyro articles are used at specially prepared sites as simulators of hand fragmentation, smoke, noise and marker grenades.
Hand imitation grenades are equipped with pyro element and retarder assy. All structural parts of grenades including safety lever are made of safe foamed polyurethane. Original designed retarder provides a stable time before activation. The grenades are equipped with dual system of protection against spontaneous operation. Proposed grenade is additionally provided with safety lever, which prevents actuation when retained. The pyro element provides realistic sound effect, at that it is safe both for probable ignition of dry grass and leaves and for spontaneous operation.
Grenade is hand thrown after pulling off the primer ring. Grenade burst occurs after operation of the retarder system under action of pressure of gasses generated by pyro element operation inside the casing.
