A safety monitoring device is provided for fire extinguishing systems that includes a main body couplable to any type of head of fire extinguishing systems. The safety monitoring device is screwed on between the discharge valve or device, that incorporates the fluid outlet as well as electric, pneumatic, hydraulic, or manual activation and the thread of the valve. The safety monitoring device further includes a sensor connected to an electronic board and through it, to a control room, programmable automaton, or other control means of the extinguishing system, that detects whether the head is correctly screwed on and that, if it is not, sends a signal, through the electronic board to the control room of the installation. Preferably, the sensor is a push-button termination that protrudes at the lower part of the main body and when fully screwing on the device it contacts the surface of the valve.

A portable fire extinguishing apparatus, which comprises a casing (20) and a cartridge (3) arranged inside the casing (20). The top end of the cartridge (3) is fixedly connected with the casing (20) through a snap ring (24); the bottom of the cartridge (3) is fixedly connected with the casing (20) through some nuts and bolts; and an explosion venting unit (2) is arranged at the jet end of the cartridge (3). Kinetic energy generated from explosion is consumed through shifting and limiting processes of the explosion venting units (2), therefore recoil force or forward impact force generated after explosion of explosives can be consumed or released, so that safe and effective explosion venting is achieved and hurt to human bodies or articles after explosion of grains is avoided.

Fluid tanks in a hospital or similar environment include sensors to detect, e.g., state and location, which can be communicated to a central station where this data can be processed to permit predictions of resource usage and enable automated management of the fluid tanks.
