Abstract

A method for protecting a user in an enclosed environment includes providing an enclosed environment that holds cargo that has first odor; flowing a gas to the enclosed environment; and adding an odorant having a second odor to the gas, the first odor being distinctive from the second odor such that a presence of the second odorant provides a warning that the gas is present.

Claims

1. A method for protecting a user in an environment, said method comprising;

flowing a gas to said environment having a first odor;

adding an odorant having a second odor to said gas, said first odor being distinctive from said second odor such that a presence of said second odorant provides a warning that said gas is present.

2. The method of claim 1 wherein said second odor is chosen from a group of Esters, Terpenes, Cyclic Terpenes, Aromatics, Alcohols, Aldehydes, Ketones, or Lactones.

3. The method of claim 1 wherein said second odor is chosen from a group of Methylphospine, Dimethylphosphine, Nerolin, Tetrahydrothiophene, 2,4,6-Trichloroanisole or Substituted pyrazines.

4. The method of claim 1 further comprising educating users that a chosen second odor is a warning that gas is present.

5. The method of claim 1 further comprising inserting said odorant into a fire suppressant system.

6. The method of claim 5 wherein said fire suppressant system is in a cargo bay of an aircraft that is separate from a passenger compartment of the aircraft.

7. The method of claim 5 wherein said gas is an inert gas.

8. A method for protecting a user in an enclosed environment, said method comprising;

flowing an inert gas to an enclosed environment having a first odor;

adding an odorant having a second odor to said inert gas, said first odor being distinctive from said second odor such that a presence of said second odorant provides a warning that said inert gas is present and said second odor does not cause concern in humans adjacent said enclosed environment.

9. The method of claim 8 wherein said second odor is chosen from a group of Esters, Terpenes, Cyclic Terpenes, Aromatics, Alcohols, Aldehydes, Ketones, or Lactones.

10. The method of claim 8 wherein said second odor is chosen from a group of Methylphospine, Dimethylphosphine, Nerolin, Tetrahydrothiophene, 2,4,6-Trichloroanisole or Substituted pyrazines.

11. The method of claim 8 further comprising educating users that a chosen second odor is a warning that inert gas is present.

12. The method of claim 8 further comprising inserting said odorant into a fire suppressant system

13. The method of claim 12 wherein said fire suppressant system is in a cargo bay of an aircraft that is adjacent to a passenger compartment of said aircraft.

14. A method for protecting a user in an enclosed environment, said method comprising;

providing an enclosed environment holding cargo having a first odor;

providing a passenger compartment adjacent said cargo area;

providing a fire suppressant system,

flowing an inert gas from said suppressant system to said enclosed environment;

adding an odorant having a second odor to said inert gas, said first odor being distinctive from said second odor such that a presence of said second odorant provides a warning that said inert gas is present and said second odor does not cause concern in humans adjacent said enclosed environment.

15. The method of claim 14 wherein said second odor is chosen from a group of Esters, Terpenes, Cyclic Terpenes, Aromatics, Amines, Alcohols, Aldehydes, Ketones, Lactones, or Thiols.

16. The method of claim 14 wherein said second odor is chosen from a group of Methylphospine, Dimethylphosphine, Nerolin, Tetrahydrothiophene, 2,4,6-Trichloroanisole or Substituted pyrazines.

17. The method of claim 14 further comprising educating users that a chosen second odor is a warning that inert gas is present.

18. The method of claim 14 further comprising inserting said odorant into a fire suppressant system.

19. The method of claim 18 wherein said fire suppressant system is in an aircraft.

20. The method of claim 14 wherein said gas is an inert gas.
