PCT No. PCT/SE94/00907 Sec. 371 Date Apr. 3, 1996 Sec. 102(e) Date Apr. 3, 1996 PCT Filed Oct. 3, 1994 PCT Pub. No. WO95/10329 PCT Pub. Date Apr. 20, 1995A preventive safety system may be used in a process in which loosely formed process material is produced in a first unit (1) and is transportable to a receiving, second unit (2), and in which process the treatment of material in the first unit is liable to generate a hazardous particle or particles which has/have a temperature which is sufficiently high to initiate burning and/or an explosion in at least the second unit. The requisite transportation of the loosely formed material between the first unit and the second unit is effected through the medium of a stabilizing zone (7), an indicating zone (8) operative in indicating the presence of hazardous high-temperature particles, and an extinguishing zone (9), wherein the indicating zone (8) includes one or more hazardous particle sensors, wherein the sensors coact with an indicating and activating unit (12) such that when the presence of hazardous high-temperature particles is detected by a sensor (10) a device (15) is activated by the indicating and activating unit. The device (15) is located in the extinguishing zone and functions to deliver an extinguishing agent and/or to remove said hazardous particles from the system. A detection-dependent intensity can be evaluated in the activating unit (12) and that measure or procedure which is most suitable at that time selected in the indicating and activating unit (12) from a number of available safety measures and safety procedures (19, 20, 21). |
