This invention is geared at attacking the scourge of explosive fires, burns, environmental pollution, or other such hazards associated with the use, transport, and storage of fuels and other hazardous substances, before they occur, including the explosion hazard present in many automotive rear-end collisions. This is achieved by swiftly reacting a "disabler" or "neutralizer" with the hazardous substance, voluntarily or by automation, on the occurrence of predetermined events that position the hazardous substance to threaten a greater than desired risk of harm. According to one of the preferred embodiments of this invention, the formation of combustion vapors in the ullage of fuel tanks is altogether prevented.

The product fill system of claim 1 wherein the mode valve has first, second, third, and fourth ports. 3. The product fill system of claim 2 wherein the mode valve, when disposed in the fill mode, has communication between the first, second, and third ports and the fourth port is not in communication with other ports. 4. The product fill system of claim 3 wherein the mode valve, when disposed in the clean mode, has communication between the first and fourth ports and separate communication between the second and third ports. 5. The product fill system of claim 4 wherein the mode valve, when disposed in the clean mode, is operable to pass cleaning material from the third port to the second port. 6. The product fill system of claim 5 further comprising a shock tube valve between the mode valve and the first end of the shock tube, the shock tube valve being closed when the mode valve is in the fill mode and being open when the mode valve is in the clean mode. 7. The product fill system of claim 1 wherein, with the mode valve in fill mode, any overpressure caused by shut off of the filler valve will travel through the mode valve to enter the second end of shock tube. 8. A product fill system comprising: a source of product supplied along in a circuit; a filler valve at a fill end of the circuit such that product flows in a path from the source through the filler valve during a fill operation; a shock tube in communication with the circuit, but off the path, the shock tube having first and second ends; and a mode valve connected to the circuit and wherein the shock tube is connected to the path via the mode valve; and wherein the mode valve has at least two modes: a fill mode in which any overpressure caused by shut off of the filler valve will travel through the mode valve into the second end of the shock tube; and a clean mode in which passage of cleaning material from upstream of the mode valve on the path is directed from the mode valve through the first end of the shock tube and out the second end of the shock tube towards the filler valve. 9. The product fill system of claim 8 wherein, in the clean mode, the mode valve directs cleaning material from the second end of the shock tube towards the filler valve via the mode valve. 10. The product fill system of claim 8 wherein the mode valve has first, second, third, and fourth ports. 11. The product fill system of claim 10 wherein the mode valve, when disposed in the fill mode, has communication between the first, second, and third ports and the fourth port is not in communication with other ports. 12. The product fill system of claim 10 wherein the mode valve, when disposed in the clean mode, has communication between the first and fourth ports and separate communication between the second and third ports. 13. The product fill system of claim 4 wherein the mode valve, when disposed in the clean mode, is operable to pass cleaning material from the third port to the second port. 14. The product fill system of claim 13 further comprising a shock tube valve between the mode valve and the first end of the shock tube, the shock tube valve being closed when the mode valve is in the fill mode and being open when the mode valve is in the clean mode. 15. The product fill system of claim 14 wherein, with the mode valve in fill mode, any overpressure caused by shut off of the filler valve will travel through the mode valve to enter the second end of shock tube. 16. The product fill system of claim 8 further comprising a shock tube valve between the mode valve and the first end of the shock tube, the shock tube valve being closed when the mode valve is in the fill mode and being open when the mode valve is in the clean mode. 17. The product fill system of claim 8 wherein, with the mode valve in fill mode, any overpressure caused by shut off of the filler valve will travel through the mode valve to enter the second end of shock tube. 18. A method of using a product fill system having a product source, a filler valve connected to the product source by a circuit and from which product is dispensed, and a shock tube to absorb overpressure from shutting of the filler valve, the shock tube having first and second ends, the steps comprising: using a mode valve to dispose the system in a fill mode in which the product goes from the product source through the mode valve to the filler valve and in which any overpressure from the closing of the filler valve passes through the mode valve and enters the second end of the shock tube; and switching the mode valve into a clean mode such that cleaning material passes from the circuit upstream of the mode valve through the mode valve to the first end of the shock tube and out the second end of the shock tube. 19. The method of claim 18 wherein, with the mode valve in fill mode, any overpressure caused by shut off of the filler valve will travel through the mode valve to enter the second end of shock tube. 20. The method of claim 19 wherein the mode valve has first, second, third, and fourth ports and wherein the switching of the mode valve into clean mode allows communication between the first and fourth ports and separate communication between the second and third ports.
