heal.abstract	In this paper, extremely low frequency (ELF) magnetic fields (MFs) were measured during the temperature-rise test of various electrotechnical equipment. The number of workers subjected to magnetic fields from the temperature-rise test is small; however, the exposure can be significant as the testing currents can be in the order of hundreds amperes. The resultant magnetic field during testing can exceed the ICNIRP limits for occupational exposure. The magnetic field exposure was recorded and statistical measures were extracted for three electrotechnical apparatus. It was found that the Time-Weighted Average exposure per unit current can reach 0.0598 μT/A. Additionally, in order to mitigate the exposure, a rule of thumb regarding safety distances has been proposed. It is shown that the use of this rule of thumb can reduce the magnetic field exposure. © 2012 Elsevier Ltd. All rights reserved.	en
