Abstract
A climate change reducing malodorous composition of matter that contains a liquid mercaptan mixed with a solvent, trans-1,3,3,3-tetrafluoroprop-1-ene, and a flame suppression component, trans-1-chloro-3,3,3-trifluoropropene, and with an inert gas such as nitrogen or carbon dioxide under pressure in a container for introduction into a pressurized breathing or pneumatic tool system, such as in mines, thereby forming a warning system to warn a person of danger when the malodorous composition of matter is released from the container.
Claims19
A malodorous warning composition of matter which is nonflammable and climate change reducing for introduction into a pressurized air breathing system of a facility to warn a person of danger, comprising:
- about 1-3 parts by weight of a liquid malodorous substance selected from the group consisting of methyl mercaptan, ethyl mercaptan, propyl mercaptan, butyl mercaptan, and tetrahydrothiophene;
- about 1-3 parts by weight of a mixture comprising trans-1,3,3,3-tetrafluoroprop-1-ene, as a nonflammable solvent, and trans-1-chloro-3,3,3-trifluoropropene, as a flame suppression component;
- and
- from about 0.1 to about 1.0 parts by weight of an inert gas under pressure, wherein the amount of trans-1,3,3,3-tetrafluoroprop-1-ene varies with balance of the mixture being trans-1-chloro-3,3,3-trifluoropropene;
- and
- wherein the mixture has a range between 200 grams and 2500 grams;
- and
- wherein the malodorous warning composition for introduction into the pressurized air breathing system operates between 50° F. and 130° F.
A malodorous warning composition of matter which is nonflammable and climate change reducing for introduction into a pressurized air breathing system of a facility to warn a person of danger, comprising:
- about 1-3 parts by weight of dimethyl sulfide;
- about 1-3 parts by weight of a mixture comprising trans-1,3,3,3-tetrafluoroprop-1-ene, as a nonflammable solvent, and trans-1-chloro-3,3,3-trifluoropropene, as a flame suppression component;
- and
- from about 0.1 to about 1.0 parts by weight of an inert gas under pressure,
- wherein the amount of trans-1,3,3,3-tetrafluoroprop-1-ene varies with balance of the mixture being trans-1-chloro-3,3,3-trifluoropropene;
- and
- wherein the mixture has a range between 200 grams and 2500 grams;
- and
- wherein the malodorous warning composition for introduction into the pressurized air breathing system operates between 50° F. and 130° F.
A malodorous warning composition of matter which is nonflammable and climate change reducing for introduction into a pressurized air breathing system of a facility to warn a person of danger, comprising:
- about 1-3 parts by weight of ethyl iso-propyl sulfide;
- about 1-3 parts by weight of a mixture comprising trans-1,3,3,3-tetrafluoroprop-1-ene, as a nonflammable solvent, and trans-1-chloro-3,3,3-trifluoropropene, as a flame suppression component;
- and;
- from about 0.1 to about 1.0 parts by weight of an inert gas under pressure, wherein the amount of trans-1,3,3,3-tetrafluoroprop-1-ene varies with balance of the mixture being trans-1-chloro-3,3,3-trifluoropropene;
- and
- wherein the mixture has a range between 200 grams and 2500 grams;
- and
- wherein the malodorous warning composition for introduction into the pressurized air breathing system operates between 50° F. and 130° F.
A warning system for introducing a malodorous warning composition of matter which is nonflammable and climate change reducing into an air breathing system or pneumatic tool system of a facility having an air pressure of about 150 pounds per square inch, to warn a person therein of danger, comprising:
- a high pressure container equipped with valve means at one end;
- about 1-3 parts by weight of a liquid malodorous substance inside said container;
- about 1-3 parts by weight of a mixture comprising trans-1,3,3,3-tetrafluoroprop-1-ene, as a nonflammable solvent, and trans-1-chloro-3,3,3-trifluoropropene, as a flame suppression component, for said liquid malodorous substance, said mixture having a maximum vapor pressure of less than 100 pounds per square inch at sea level and a temperature of about 25 degrees C. inside said container;
- from about 0.1 to about 1.0 parts by weight of an inert gas under pressure inside said container, whereby a pressure of at least 240 pounds per square inch is produced inside said high pressure container, and
- connecting means connecting said valve means of said container to valve means of the air breathing system or pneumatic tool system of a facility;
- and
- wherein the mixture has a range between 200 grams and 2500 grams;
- and
- wherein the malodorous warning composition for introduction into the pressurized air breathing system operates between 50° F. and 130° F.
