The hypothesis being tested was that the exposure of female workers to the electromagnetic field (EMF) emitted by an induction hob (IHb) meeting public exposure limitations (evaluated according to EN/IEC 62233) is also compliant with European Directive 2013/35/EU on workers’ protection. The electric field induced in three female models in a realistic ergonomically comfortable posture near IHb was evaluated using numerical models of 25 kHz EMF sources (IHb covered by cooking vessels). It was found that, in analyzed ergonomically comfortable exposure situations, the electric field induced in the user's body may exceed public and workers’ limits when the vessels do not match the dimensions of IHb's heating zone. This can even be the case when IHb complies with Conformité Européenne labeling requirements (i.e. EMF exposure falls below public limits 30 cm away from IHb edge). In the 36 exposure scenarios analyzed, statistically significant differences were found when the distances from IHb and vessel dimension, and the height and body mass index of models in exposure scenarios varied, but not between the use of models of pregnant and nonpregnant women. The use of IHb complying with European requirements on general public protection does not ensure that EMF exposure to workers complies with the relevant limits. Adequate protection measures need to address these occupational environmental hazards. © 2020 Bioelectromagnetics Society.

在人体工程学的声音暴露情况下,评估磁场对电磁炉女性使用者的影响。

检验的假设是,女工暴露于满足公共暴露限制(根据EN / IEC 62233评估)的电磁炉(IHb)发射的电磁场(EMF)中,也符合欧洲指令2013/35 / EU保护工人。使用25 kHz EMF源(烹饪锅覆盖的IHb)的数值模型评估了三个女性模型在接近IHb的人体工程学舒适姿势中感应的电场。结果发现,在经过人体工程学分析的舒适暴露情况下,当容器与IHb加热区的尺寸不匹配时,在用户体内感应的电场可能会超过公共和工作人员的极限。当IHb符合欧洲ConformitéEuropéenne标签要求时(例如 EMF暴露量低于IHb边缘30厘米的公共限值。在所分析的36种暴露情景中,当与IHb的距离和血管尺寸以及模型在暴露情景中的高度和体重指数发生变化时,发现统计学上的显着差异,但在使用孕妇和未怀孕妇女的模型之间则没有统计学差异。使用符合欧洲关于一般公共保护要求的IHb不能确保EMF对工人的暴露符合相关限制。需要采取足够的保护措施来解决这些职业环境危害。©2020生物电磁学会。并且在暴露场景中模型的身高和体重指数各不相同,但在使用孕妇和非孕妇模型之间没有差异。使用符合欧洲关于一般公共保护要求的IHb不能确保EMF对工人的暴露符合相关限制。需要采取足够的保护措施来解决这些职业环境危害。©2020生物电磁学会。并且在暴露场景中模型的身高和体重指数各不相同,但在使用孕妇和非孕妇模型之间没有差异。使用符合欧洲关于一般公共保护要求的IHb不能确保EMF对工人的暴露符合相关限制。需要采取足够的保护措施来解决这些职业环境危害。©2020生物电磁学会。
