В работе представлены результаты гигиенической оценки уровней напряжённости электрического и магнитного полей промышленной частоты и функционального состояния организма человека при использовании экранирующих средств индивидуальной защиты от электрических полей промышленной частоты на открытых распределительных устройствах напряжением 220–750 кВ в тёплый период года.</p><p>Цель исследования — исследование функционального состояния организма человека, использующего средства индивидуальной защиты от электрических полей промышленной частоты во время работ на открытых распределительных устройствах напряжением 220–750 кВ, и возможность их регламентации в зависимости от тепловой нагрузки среды.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Измерения уровней электрических и магнитных полей промышленной частоты осуществлялись в соответствии с МУК 4.3.2491-09. В исследовании по оценке функционального состояния организма человека при использовании средств индивидуальной защиты от электрических полей промышленной частоты участвовало 8 добровольцев. Добровольцы выполняли работу электротехнического персонала в течение 60 минут с последующим 30-минутным восстановлением. Контроль параметров окружающей среды проводился на основании измерений индекса тепловой нагрузки среды. Регистрировались показатели, такие как температура и влажность кожи, температура и влажность пододёжного пространства, влагопотери.</p></sec><sec><title>Результаты</title><p>Результаты. На рассматриваемых электросетевых объектах зафиксированы превышения ПДУ электрического поля промышленной частоты до 30 кВ/м, в связи с этим обязательным является использование средств индивидуальной защиты. Полученные результаты исследований функционального состояния организма человека выявили тенденцию к росту напряжения механизмов терморегуляции организма человека, использующего средства индивидуальной защиты от электрических полей промышленной частоты во время проведения работ на открытых распределительных устройствах. </p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования.

Регламентация режимов труда и отдыха персонала при работе на открытой территории в тёплый период года по индексу тепловой нагрузки среды требует корректировки, поскольку проведённые исследования показали необходимость более строгой регламентации по времени при эксплуатации средств индивидуальной защиты от электрического поля промышленной частоты в нагревающей среде с учётом их влияния на тепловое и функциональное состояние организма человека.</p></sec><sec><title>Этика</title><p>Этика.

The paper presents the results of a hygienic assessment of the intensity levels of electric and magnetic fields of industrial frequency and the functional state of the human body when using shielding personal protective equipment against electric fields of industrial frequency on open switchgears with a voltage of 220–750 kV in the warm season.</p><p>The study aims to explore the functional state of the human body using personal protective equipment against industrial frequency electric fields during work on open switchgears with a voltage of 220–750 kV, and the possibility of their regulation depending on the thermal load of the environment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The specialists measured the levels of electric and magnetic fields of industrial frequency in accordance with MUK 4.3.2491-09. Eight volunteers took part in the study to assess the functional state of the human body when using personal protective equipment against industrial frequency electric fields. Volunteers performed the work of electrical personnel for 60 minutes followed by a 30-minute recovery. We monitored environmental parameters based on measurements of the environmental heat load index and recorded indicators such as skin temperature and humidity, temperature and humidity under clothing, moisture loss.</p></sec><sec><title>Results</title><p>Results. At the considered electric grid facilities, the researchers recorded the excess of remote adjustment of the electric field of industrial frequency up to 30 kV/m, in this regard, the use of personal protective equipment is mandatory. The obtained results of studies of the functional state of the human body revealed a tendency to increase the voltage of the mechanisms of thermoregulation of the human body using personal protective equipment against electric fields of industrial frequency when working on open switchgear.</p></sec><sec><title>Limitations</title><p>Limitations. The number of volunteers was due to limited access to production facilities.</p></sec><sec><title>Conclusion</title><p>Conclusion. The regulation of work and rest modes of personnel when working in an open area during the warm season according to the index of the thermal load of the environment requires adjustment, since the studies have shown the need for stricter time regulation when operating personal protective equipment against an electric field of industrial frequency in a heating environment, taking into account their influence on the thermal and functional state of the human body.</p></sec><sec><title>Ethics</title><p>Ethics.
