Oil well blow-out safety system
A system for delaying the ignition of, or for extinguishing, an oil well rig fire, by injecting an admixture of for example pressurized CO2 and mono-potassium phosphate into the flow of hydrocarbons from the drill pipe and casing, through a plurality of holds in the wall of a spool apparatus located in the ''stack'' above the ''hydril'' and blow-out preventers and above the casing but preferably below the mud return line element. The spool apparatus is equipped with a plurality of one-way check valves for receiving a plurality of conduits or chicksaw lines for transporting the chemicals from storage tanks to the spool apparatus. The entire system can be manually activated by a spring-loaded mechanism at the control head. Additionally, the system can be used to inject, for example, ammonium hydroxide to neutralize highly toxic gases, known as ''sour'' gases, arising during a blow-out.
