    Manual and automatic system and firefighting procedure in operating rooms. Object of the invention
    The present invention relates to a specific extinguishing system for operating rooms that can either be manual or automatic.
    No operating room has a manual or automatic fire extinguishing system. This is because the extinguishing agents act on the oxygen concentration or are not clean (in the case of a sterile zone).
    The system is based on the use of the molecule called NOVEC 1230, chemical formula CF3CF2C (O) CF (CF3) 2, which does not destroy the ozone layer (ODP 0), with low global warming potential (GWP 1) and life time in the atmosphere less than 5 days, and that has a high safety factor, since there is a notable distance between the design concentrations (between 5.3% and 6%) and the NOAEL limit ((No Observed Adverse Effects Level) Highest exposure level at which no adverse effect is observed) - highest concentration at which no physiological or toxic adverse effect has been observed - which is 10%.
    Therefore, the invention is based on the use of said gas applied to the components of an extinguishing system in operating rooms, both with people inside and in the absence thereof.
    The advantages of this invention are the following:
    -It is safe for people.
    -It is characterized by its rapid and effective penetration in the area to be protected.
    -It does not generate waste and minimizes damage to property and high value equipment. He
    gas will not damage the material stored in the rooms in case of discharge.
    -For design concentrations it is not harmful to the health of people with
    a very high safety margin.
    -It does not destroy the ozone layer.
    -It is safe against the greenhouse effect.
    -Its duration in the atmosphere is only 5 days.
    The industrial application of this invention is within fire extinguishing systems, and more specifically manual and automatic fire extinguishing systems in operating rooms. Background of the invention
    Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related to it.
    Thus, document ES2269432T3 refers to a prefabricated breathable, fire prevention or fire suppression hypoxic composition to provide a breathable atmosphere for fire prevention or fire suppression in enclosed spaces, said composition being ready for use to inject into said spaces. and comprising a gaseous mixture containing oxygen and nitrogen, characterized in that said gaseous mixture contains more than 12% and less than 18% oxygen for permanent use as a fire prevention atmosphere; or said mixture contains more than ES1007091U describes an improved flame retardant unit, to quench flames in fires, composed of a fire blanket arranged on a support and that: a) the support is structured in a pocket body open frontally to accommodate the blanket and mounted with possibility of turning in a supporting frame, arranged, in turn in a fixed place; said pocket body presenting lateral concavities to allow easy access to the pockets-handle of the blanket; b) the blanket is structured in a quadrangular plan body that, in relation to two contiguous vertex zones, has two separate handgrip pockets arranged on the same face, the blanket being in storage position, zigzag folded on itself with the pockets -asidero oriented outward and housed in the body-pocket of the support. The fire retardant unit applies a totally different system to that described in the main invention for fire extinguishing.

    Thus, ES2080733T3 refers to an inhibition of the progress of fire in a building along the aeration channels, for this purpose a wire fence of highly heat-resistant material such as stretched metal is conditioned in the transverse of the aeration channel which diverts heat to the walls of the aeration channel, which prevents the flame from passing through or delaying its appearance. As a wire fence of this type becomes dirty during the aeration installation service, it must be possible to change it easily and be able to clean, for this reason it is advisable to place the filling in the form of stretched metal balls as spilled in a firm intermediate space of cross braces or drilled plates etc. The system described in said invention proposes the use of wiring of heat-resistant material to inhibit the progress of fire while the system described in the main description focuses on extinguishing it by means of the gas described.
    Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does. Description of the invention
    The manual and automatic fire extinguishing system in operating rooms object of the present invention is constituted from an installation formed by a fire extinguishing center, fire detection, firing buttons, blocking buttons and signposts in the accesses , alarm sirens, bottles with extinguishing agent (NOVEC 1230 of chemical formula CF3CF2C (O) CF (CF3) 2), and diffusers in the environment.
    The fire detection system is formed by an aspiration detector connected to the extinguishing plant, with several sampling so that the automatic operation of the installation is produced by the alarm entry of two safety levels according to the degree of darkening of the smoke sample analyzed by the aspiration detector. The opening of the bottle is automatic by solenoid valves or fulminant and manual by lever.
    The extinction will be in an independent environment for each operating room.
    The operation and commissioning of the system takes place in the following stages:
    I.-The extinguishing installation will be commanded by the action of two groups of detection levels: the operation of the first triggered only a preventive alarm consisting of an acoustic signal.
    II.-When the 2nd group reacts (or by the action of a trigger button) the extinction alarm is produced consisting of an acoustic signal complemented with optical signals that III. -After a certain delay time, the cylinder containing the agent, under a pressure of 25 bar, opens through an electrical signal and said agent, still liquid at that point, flows towards the nozzles where it vaporizes.
    image3
    IV. -The gas at that time is distributed by the operating room.
    V. -Since the NOVEC 1230 is liquid at room temperature, refilling the cylinders is easy and fast, and can be done on site. The agent is introduced into the cylinder and pressurized with nitrogen up to 25 bar. It is not necessary to disassemble the cylinder or move it to an outside filling station.
    In areas that can be occupied, the following security measures will be applied:
    - Obstacle-free exit routes, emergency lighting and signaling.
    -Automatic or manual closing doors (sliding or swinging) that open outwards (hinges) and can be opened from the inside even when they are locked from the outside.
    -Media for the natural or forced ventilation of the areas after the discharge of the agent. Measures should be taken to dissipate dangerous atmospheres and not simply move them to other areas. The system will send a signal to the air conditioning system to put it into operation and thus renew the air in the operating room by extracting the smoke inside. Brief description of the drawings
