Nonbeam Hazards
Published in Ken Barat, Laser Safety Management, 2017
Although a current may not pass through vital organs or nerve centers, internal electrical burns can still occur. These burns, which are a result of heat generated by current flowing in tissues, can be either at the skin surface or in deeper layers (muscles, bones, etc.) or both. Typically, tissues damaged from this type of electrical burn heal slowly. Burns caused by electric arcs are similar to burns from high-temperature sources. The temperature of an electric arc, which is in the range of 4,000 to 35,000°F, can melt all known materials, vaporize metal in close proximity and burn flesh and ignite clothing at distances up to 10 ft from the arc.

The most common shock-related, nonfatal injury from electricity is burns. Burns caused by electricity may be of three types: electrical burns, arc burns, and thermal contact burns. Electrical burns can result when a person touches electrical wiring or equipment that is used or maintained improperly. Typically, such burns occur on the hands. Electrical burns are one of the most serious injuries you can receive and need to be given immediate medical attention. Additionally, clothing may catch fire, and a thermal burn may result from the heat of the fire.5

The term ‘electrical burn’ is usually used to indicate the variety of injuries caused by supraphysiologic electrical energy interacting with living tissue, often linked to electrosurgical procedures. Electrical injuries occur when the human body comes in contact with an electrical source, either directly or through material that is a conductor. Interference between electrosurgical energy and active implants has been thoroughly discussed in the scientific literature (Saaiq et al. 2012; Park et al. 2014; Bae et al. 2018, Martinsen et al. 2019). Both alternating current (AC) and direct current (DC) produce a wide variety of biological effects at the cellular and tissue levels (Phillips et al. 2008). The higher the voltage and amperage, the greater the ensuing electrical injury (for the same duration of exposure) (Petri et al. 2017).

Mining industry can affect human health and endangers human existence directly and indirectly. The workers in the mining areas are the first and the most exposed to the risk. In general, the first risk is accidents. Elgstrand and Vingård (2013) reported that gas, gas intoxications, dust explosions, improper use of explosives, electrical burn, fires may cause the accidents, collapsing of mine structures; rock falls from roofs and side walls, flooding, workers stumbling/slipping/falling, or errors from malfunctioning, or improperly used mining equipment. The same authors mentioned that only in China alone from 1949 to now more than 250,000 Chinese miners have died in mining accidents and since 1850, more than 100,000 miners have been killed in U.K. The second important direct risk is the long-term exposure to mine dust. The mine workers and local citizens can be exposed to metals in the mine dust by Inhalation, ingestion, and dermal contact (Olafisoye, Adefioye, & Osibote, 2013). Human health can be affected indirectly by the consumption of contaminated water (Dinis & Fiùza, 2011; Olafisoye et al., 2013), vegetables grown in mine soil (Candeias et al., 2014; Nelson, 2016; Walden, 2005), and animals meat already affected by metals (Nouri et al., 2016b; Dinis & Fiùza, 2011). According to numerous works, the metals in the mine dust induced several diseases, such as respiratory disease (Laney & Weissman, 2014), morphological abnormalities, neuro-physiological disturbances, genetic alteration of cells (mutation), tetratogenesis and carcinogenesis (Abdul-wahab & Marikar, 2012; Okoro, Fatoki, Adekola, Ximba, & Snyman, 2012), mental retardation in children and kidney disease, and anemia (Nouri & Haddioui, 2016a). Moreover, metal toxicity can cause depression, headache, fits, anxiety, and irritability in their behavior (Gilani et al., 2015).
