2. Fire extinguisher - Wikipedia

   en.wikipedia.org/wiki/Fire_extinguisher

   An anecdotal report of a carbon dioxide fire extinguisher was published in Scientific American in 1887 which describes the case of a basement fire at a Louisville, Kentucky pharmacy which melted a lead pipe charge with CO 2 (called carbonic acid gas at the time) intended for a soda fountain which immediately extinguished the flames thus saving ...

3. Liquid carbon dioxide - Wikipedia

   en.wikipedia.org/wiki/Liquid_carbon_dioxide

   Liquid carbon dioxide is the liquid state of carbon dioxide (CO 2 ), which cannot occur under atmospheric pressure. It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (88.0 °F) (temperature of critical point ) and above −56.6 °C (−69.9 °F) (temperature of triple point ). [ 1 ]

   Effective fire suppression requires introducing a concentration of the HFC-227ea agent between 6.25% and 9% depending on the hazard being suppressed. Its NOAEL for cardiac sensitization is 9%. The United States Environmental Protection Agency allows concentration of 9% volume in occupied spaces without mandated egress time, or up to 10.5% for a ...

   Halon 1211 is also a potent greenhouse gas with a 100-year global warming potential 2,070 times that of carbon dioxide and an atmospheric lifetime of 16.0 years. [6] Recycling of Halon 1211 allows it to remain in use, [7] [8] although parts availability is limited to a few manufacturers and can be an issue. Halon 1211 is still widely used in ...

   Fire extinguisher that releases carbon dioxide gas to displace oxygen to smother and cool a fire, such as a flammable liquid. Combination nozzle A low pressure fog nozzle (usually 120 to 150 lbf/in² or 820 to 1030 kPa that can be adjusted to produce a near straight stream. Also commonly referred to as a Taskforce tip (TFT).
