Analysis of Radio Frequency Risks in Flammable and Explosive Environments

Abstract

In this paper, the mechanism of radio frequency (RF) causing fire and explosion directly and indirectly was recommended, studies of RF risks in flammable and explosive environments were summarized, some problems in RF risk researches recently were discussed, study prospects of RF risks in flammable and explosive environments were analyzed. The fact that the mechanisms and conditions of RF igniting combustible gases should be researched by more deeply theories and technological means, and that RF security standards should be laid down and a complete and precise RF security assessment system should be established in flammable and explosive environments was put forward.

Improvement of Risk Assessment Using Numerical Analysis for an Offshore Plant Dipole Antenna

“…resonance frequency 3dB Bandwidth (6) f t is the frequency of the transmission used in the assessment, 163 MHz, and f r and Q k are obtained through calculation. f r is the resonance frequency of the structure and is determined to be the most conservative value at which the ratio of f t :f r is 1.0 with reference to Figure 2.…”

“…The risk of fires and explosions in the explosion environment was evaluated by calculating the energy generated by sparks in the conductive structure caused by electromagnetic waves, and safety measures for the risk of radio frequency (RF) ignition were suggested. Wang [6] recommended RF mechanisms that directly or indirectly cause fires and explosions and summarized RF risk studies in flammable and explosive environments. In addition, some issues of RF risk studies were discussed, and RF risk studies were conducted.…”
