    Protection against ignition and detonations initiated by RF radiation is considered. The author discusses progress towards realistic standards and the legal background. British Standard BS6656 and the requirements of the Health and Safety at Work Act are described View full abstract»

    Radiowaves induce currents in metallic structures and may cause sparking if there is a gap in the structure. The power dissipated in the spark may be sufficient to ignite a flammable atmosphere if the radio wave is strong enough. The author discusses the calculation of the strengths of waves radiated by different types of transmitters. The formulae quoted are to be found in British Standard 6656 a... View full abstract»

    Unwanted induced currents due to electromagnetic radiation can cause sparks to occur and ignition of gases is possible. There is thus a potential incompatibility between radio transmitters and gas/petrochemical processing plant, an issue which has been addressed in detail in the UK over the last fifteen years. The author describes practical on-site measurements at the St. Fergus gas processing pla... View full abstract»

  • Problems in design of ignition test cells for use with pulsed radar sources

    The results of a detailed study of breakdown phenomena and flammable gas ignition in a fixed-gap ignition cell fed by a pulsed radar source are presented. It is reasoned that the large electrode gap widths that are necessary with hydrocarbon fuels lead to a situation where any spark that occurs is certain to cause ignition, and the probability of ignition is determined by the probability of occurr...

    The operators of tanker lorries carrying petroleum products want to have radio telephones fitted to the cabs of their vehicles. Members of the Institute of Petroleum's Electrical Engineering Committee, in their efforts to prepare a code of practice for the safe use of radio telephones in these vehicles, recognised that British Standard BS 6656:1986 gave guidance on the subject of RF ignition of fl...
