PCT No. PCT/GB90/01542 Sec. 371 Date Feb. 8, 1993 Sec. 102(e) Date Feb. 8, 1993 PCT Filed Oct. 8, 1990 PCT Pub. No. WO92/06458 PCT Pub. Date Apr. 16, 1992.A method of training an operator in the use of first detection apparatus responsive to a first sensible emission of a hazardous nature, e.g. radio-active or ionizing radiations or toxic gases or vapors from war gases or nerve gases, and involves training the operator in the use of an alternative second detection apparatus responsive to a second sensible emission of a non-hazardous nature. For use in such a training method, there is provided, in combination, a self-contained movable supply of chemical, e.g. gaseous, material that in use provides a second sensible emission, and a detector responsive to the second sensible emissions and providing an indication commensurate with the level of those emissions, the indication being provided in units of the said first sensible emission. The self-contained movable supply may include one or more of: activated carbon, or silica gel, or a molecular sieve, or a nut or bolt, or a particulate material (e.g. a dust or powder), or simulated pebble, or a simulated stone, or a grease, or a sprayed-on liquid. The gaseous material may include ethylene, or butane, or a chlorinated or fluorinated hydrocarbon, e.g. chloroform. The gas detector may include an explosive atmosphere detector, or a sensitive gas lead detector, or a specific gas monitor, or an electron capture detector.
