An improved system and method for detection and suppression of fire that addresses the elements of the fire tetrahedron (e.g., heat, oxygen, fuel-rich smoke) to detect and suppress fires is described. Embodiments are comprised of a processor in communication with a detector, a fan, and a number of dampers. Upon detection of a triggering condition by the detector, the processor causes signals to be transmitted to the fan and dampers. Resulting changes to dampers and fans redirects airflow to evacuate heat, oxygen, and fuel-rich smoke through one or more vents in the compartment in which the triggering condition was detected. Advantages of described embodiments include utilizing existing HVAC systems, removing elements of the fire tetrahedron to suppress fires, and reducing unnecessary damage that may be caused by prior art suppression systems (e.g., sprinklers).

The fire extinguishing tarpaulin is configured for use extinguishing a chemical combustion reaction in an area of conflagration. The fire extinguishing tarpaulin comprises a fire tarpaulin, a rocket system, and an aircraft. The fire tarpaulin forms a gas impermeable barrier that limits the chemical combustion by limiting access to the oxygen required to sustain the chemical combustion reaction. The rocket system is a propulsion system that propels the fire tarpaulin to the chemical combustion reaction. The aircraft is a vehicle used: a) as a launching platform to deliver the fire tarpaulin to the chemical combustion reaction; and, b) a vehicle to subsequently recover the fire tarpaulin for future use.

The invention relates to an inertization apparatus for inerting a working volume in a chemical production plant by flushing with inert gas, where the chemical production plant comprises a plant-wide inert gas distribution system having pipes for distributing the inert gas and at least one inert gas offtake position which can be connected to a connecting conduit. According to the invention, it is provided that the connecting conduit between inertization apparatus and working volume is connected, at its end nearest the working volume, in a not reversibly detachable manner to an intermediate piece, where the intermediate piece can be connected in a reversibly detachable manner to a counterpiece provided on the working volume.

A fire suppression assembly includes a dome that is positionable over a stove top or a cooking pot in which a fire has started. The dome is comprised of a fluid impermeable material to inhibit oxygen from feeding the fire thereby facilitating the fire to extinguish. A receiver is coupled to and extends away from the dome. A handle is pivotally coupled to the receiver to be gripped for placing the dome over the stove top or the cooking pot. The handle is positionable in a first position has the handle extending upwardly from the receiver. Conversely, the handle is positionable in a second position has the handle extending laterally away from the receiver.
