§ Mr. Peter RobinsonTo ask the Secretary of State for Defence what assessment he has made of whether NAIAD can be triggered by the toxic compound given off from jet engines.
§ Mr. SoamesNerve agent immobilised enzyme alarm and detector is designed to be used in conditions where it would not normally be in close proximity to jet engines. Nevertheless, NAIAD was extensively evaluated against a wide range of aircraft engine effluent during acceptance tests for military use. Out of the 18 aircraft type evaluated, in only one case was alarm condition attained. It follows that, although NAIAD is not commonly triggered by compounds emitted from jet engines, circumstances might arise in which this could happen.
