Effects of the electrical arc on human beings
From the above, it is evident that the electrical arc represents a hazard source for people and goods.
The hazards to which a person is exposed due to the release of energy generated by an arc event are:
• burns;
• injuries due to ejection of materials;
• damages to hearing;
• inhalation of toxic gases.
Burns
The high temperature levels of the gases produced by the electrical arc and the expulsion of incandescent metal particles may cause more or less severe burns to people.
Flames can cause all degrees of burn up to carbonization: the red-hot solid bodies, such as the metal fragments of the assembly involved, cause third degree burns, superheated steam causes burns analogous to those by hot liquids whereas radiant heat generally causes less severe burns.
Injuries due to ejection of materials
The ejection of metal particles or other loose items caused by the electrical arc can result in severe injuries to the weakest parts of the human body as, for example, the eyes.
The materials expelled owing to the explosion produced by the arc may penetrate the cornea and hurt it.
The extent of the lesions depends on the characteristics and on the kinetic energy of these objects.
Moreover, the ocular region can sustain injuries to the mucosa because of the gases released by the arc and the emission of ultraviolet and infrared rays can injure the cornea and the retina depending on the radiation wavelengths.
Hearing
As already mentioned, the electrical arc is a real explosion, whose sound may cause permanent injuries to hearing.
Inhalation of toxic gases
The fumes produced by burnt insulating materials and by molten or vaporized metals can be toxic.
The fumes are caused by incomplete burning and are formed by carbon particles and by other solid substances suspended in the air.
[ABB]Воздействие электрической дуги на человека
Из сказанного выше совершенно очевидно, что электрическая дуга является источником опасности для людей и имущества.
При высвобождении энергии электрической дуги человек может подвергнуться следующим опасностям:
• получение ожогов;
• повреждения от выброса продуктов горения дуги;
• нарушение слуха;
• вдыхание ядовитых газов.
Ожоги
Высокая температура газов, образующихся при горении электрической дуги, и выброс раскаленных частиц металла могут явиться причиной достаточно тяжелых ожогов.
Можно получить любую степень ожогов, вплоть до обугливания. Раскаленные до красна твердые частицы, такие как металлические частицы НКУ, вызывают ожоги третьей степени. Перегретый пар вызывает ожоги, аналогичные ожогам от горячих жидкостей. Лучистая энергия вызывает менее тяжелые ожоги.
Повреждения от выброса продуктов горения дуги
Выброс металлических или иных частиц, происходящий при горении электрической дуги, может привести к серьезным телесным повреждениям, особенно при попадании в глаза.
Частицы, выбрасываемые при горении дуги, могут проникнуть в роговую оболочку глаза и повредить ее.
Степень поражения зависит от характеристик и кинетической энергии выбрасываемых частиц.
Кроме того, газы, выделяющиеся в процессе горения дуги, могут повредить слизистую оболочку глаз, а ультрафиолетовое и инфракрасное излучение – роговую оболочку и сетчатку в зависимости от длины волны воздействующего излучения.
Орган слуха
Как уже упоминалось, электрическая дуга представляет собой реальный взрыв, звук которого может нанести тяжелую травму органу слуха.
Вдыхание ядовитых газов
Продукты горения изоляционных материалов и пары металлов могут быть ядовитыми.
Дым, образующийся при неполном сгорании и содержащий частицы углерода и других веществ, попадает в окружающий воздух.
