The invention claimed is: 1. A flotation device adapted to be worn by a person, comprising: a gas generator having a solid propellant material and operable to generate gas by ignition of said solid propellant material; a battery device; a trigger for controlling said battery device to activate said ignition of the solid propellant material; and at least one inflatable member adapted to be inflated by gas generated by said gas generator. 2. A flotation device as claimed in claim 1, further comprising a body substantially encompassing said at least one inflatable member and the gas generator, and a release for substantially releasing said at least one inflatable member from the flotation device while retaining inflatable members in connection with the flotation device. 3. A flotation device as claimed in claim 2, wherein the flotation device is adapted to be worn about a person's wrist. 4. A flotation device as claimed in claim 3, wherein the flotation device is compact and dimensioned similarly to a wristwatch. 5. A flotation device as claimed in claim 2, wherein the flotation device is suitable for deployment in avalanche conditions. 6. A flotation device as claimed in claim 1, wherein the trigger includes a removable protective cap covering a flexible button device in sealing engagement with a container holding the battery device, arranged such that contact between the button device and the battery device initiates inflation of the inflatable members. 7. A flotation device as claimed in claim 6, wherein there are two inflatable members each of which is generally spherical and located on either side of the trigger. 8. A flotation device as claimed in claim 6, wherein contact between the button device and battery device is effected by a hydrostatic mechanism. 9. A flotation device as claimed in claim 1, comprising two inflatable members. 10. A flotation device as claimed in claim 9, wherein each of said inflatable members is a lobe when inflated. 11. A flotation device as claimed in claim 10, wherein each of said inflatable members is an orb when inflated. 12. A flotation device as claimed in claim 10, wherein each of said inflatable members is generally spherical when inflated. 13. A flotation device as claimed in claim 9, wherein said inflatable members extend in generally opposed directions when inflated. 14. A flotation device as claimed in claim 1, wherein said trigger includes an activating switch and a cover for removably covering said switch, wherein said switch is accessible by removing said cover.
