Non-ozone depleting malodorous composition of matter and warning system

摘要

A non-ozone depleting malodorous composition of matter that contains a liquid mercaptan mixed with a nonflammable and non-ozone depleting solvent, 1,1,1,2-tetrafluoroethane, and with an inert gas such as nitrogen under pressure in a container for introduction into a pressurized breathing 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.
