Typical hazards

Quarries and open-pit mines are working environments where the employees’ health and lives may be exposed to danger. In the process of quarrying stone controlled rock blasting by means of industrial explosives is used. In order to assure maximum safety before each explosion, it is necessary to inform the workers/employees in a quarry or open-pit mine about the coming explosion by a loud acoustic signal.

Solution description

The integrated mobile Screamer Car siren can serve this particular purpose when located in the centre of the covered area. For broken, vast or stretched areas, a more powerful siren is recommended, such as the integrated stand-alone siren Bono or the electronic siren Gibon.

The electronic siren can be controlled indirectly by a simple remote control device or directly connected to the activation button for explosion. When using the remote control device, connected either by wire or wirelessly, a variety of announcements can be defined; for example, to inform the persons concerned before rock blasting or earth-moving, to warn them against rock sliding, etc.

It is recommended to use a mobile operator’s control panel in the resistant portable Peli® box when a more complex warning system with extended warning and notification options is required.
