“…1,7 However, humans can be exposed to UVC from artificial and occupational sources such as welding. 8,9 It is estimated that more than 110 million workers across the world are subject to some form of weldingrelated exposure, whether they are full-time welders or employed in other industries such as construction, farming, ship-building or vehicle servicing. 3,10 Welders are exposed to a number of direct hazards including high heat and radiation, as well as respiratory, cardiovascular and reproductive hazards through inhalation of carcinogenic welding fumes.…”

“…3 It is known that welders are exposed to the full UV spectrum, including UVA, UVB and UVC radiation, artificially from the welding arc. 8,9 Notably, the UVR from the welding arc can result in erythema of unprotected areas of the welder's skin, particularly in the head and neck region, 10 and many welders also experience burns from radiation or flying sparks and hot metal. 11 The severity of such erythema or burns depends on factors such as distance from the source, susceptibility of the host, use of protective clothing, exposure time and wavelength.…”

“…11 However, some reports have indicated that welders do not always wear proper PPE because the work environment is hot and uncomfortable, and the equipment can seem more of a hindrance than help. 8 Increased engineering controls, promoting regular use of sunscreen when outdoors and developing more comfortable PPE could further protect welders. Nevertheless, future studies, including controlled animal studies to investigate UVR exposure from welding, are needed to better determine the risk of skin cancer in welders.…”

Summary Many workers in several different occupations can be exposed to ultraviolet radiation (UVR), which may increase their risk of developing skin cancer. Welding, an occupation employing an estimated 11 million people worldwide, is one such occupation. Welders are known to be exposed to the full spectrum of UVR from the welding arc and often experience burns and localized cutaneous erythema. In 2017, UVR from welding was classified as carcinogenic to humans based on sufficient evidence of ocular melanoma in humans. It has been hypothesized that exposure to UVR from the welding arc also may increase the risk of skin cancer among workers in this occupation. This review summarizes the current literature on skin cancer risk in welders.

“…Sunlight is comprised only of UVA and UVB light; UVC and vacuum-UV are fully attenuated by the atmosphere(16). However, exposure of skin to UVC light can occur when using welding equipment, sunbeds, or working within biosafety cabinets(17–19). In terms of overall damaging effects on full thickness skin, the World Health Organization defines UVC as the most damaging(20).…”

Prolonged exposure of human skin to sunlight causes photodamage, which induces the early onset of wrinkles and increased tissue fragility. While solar ultraviolet (UV) light is considered to have the most damaging effect, the UV range that is most harmful remains a topic of significant debate. In this study, we take a first step towards elucidating biomechanical photoageing effects by quantifying how exposure to different UV ranges and dosages impacts the mechanical and structural properties of human stratum corneum (SC), the most superficial skin layer. Mechanical testing reveals that irradiation of isolated human SC to UVA (365 nm), UVB (302 nm), or UVC (265 nm) light with dosages of up to 4000 J/cm2notably alters the elastic modulus, fracture stress, fracture strain, and work of fracture. For equivalent incident dosages, UVC degrades SC the greatest. However, upon discounting reflected and transmitted components of the incident light, a generalized scaling law relating the photonic energy absorbed by the SC to the energy cost of tissue fracture emerges. This relationship indicates that no one UV range is more damaging than another. Rather, the magnitude of absorbed UV energy governs the degradation of tissue mechanical integrity. Subsequent structural studies are performed to elucidate the cause of this mechanical degradation. UV absorption scales with the spatial dispersion of desmoglein 1 (Dsg 1), a component of corneocyte cell-cell junctions, away from intercellular sites. Combining both scaling laws, we establish a mechanical-structural model capable of predicting UV induced tissue mechanical integrity from Dsg 1 dispersion.Statement of SignificancePhotoageing from the sun can produce early onset of skin wrinkles and an increase in tissue fragility that heightens the risk of rupture. While solar ultraviolet (UV) light is considered to have the most damaging effect, the UV range that is most harmful remains a topic of significant debate. In this study, we elucidate photoageing effects by quantifying how exposure to different UV ranges and dosages impacts the mechanical and structural properties of human stratum corneum (SC), the most superficial skin layer. Results establish a mechanical-structural model that relates the amount of UV energy absorbed by the tissue, irrespective of UV range, to the energy cost of tissue fracture and spatial dispersion of desmoglein 1.

ÖZET Metallerin kesilmesi ve birleştirilmesi işlemlerinde kolay ve hızlı bir teknik olan kaynak yöntemi, imalatçılar ve tamirciler tarafından yaygın olarak kullanılmaktadır. Dünyada milyonlarca insan kaynak işleminde sağlıksız ve güvensiz şartlar altında çalışmaktadır. Kaynakçılıkta işin niteliğine bağlı uygulanan kaynak yöntemi, kaynak yapılan malzemenin kimyasal yapısı, yanma gazı, akım şiddeti, ark gerilimi, kaynak hızı ve süresi, ana malzeme üzerindeki kaplama maddeler ve boyalar, kaynakta kullanılan elektrodun yapısı gibi etkenlere bağlı riskler oluşmaktadır. Kaynakçılıktaki temel olası tehlikeler; toz, kaynak gazı ve dumanı gibi iş yeri ortam havasının kirliliği, elektromanyetik radyasyon, elektrik, gürültü, yangın ve patlama olmakla birlikte kaynakçıların kaynak dumanı yoluyla, önemli toksik metaller (Pb, Ni, FeO, Cu, Cd, F, Mn, Cr gibi) ve gazlara (CO, NO, O 3) maruz kaldıkları gösterilmiştir. Kaynak dumanının genel toksik etkileri, kaynak yapılan ortam havasında bulunan toksik gaz ve metallerin cinsine, konsantrasyonuna, maruz kalınan düzeylerine ve sigara içme alışkanlıklarına bağlı olarak değişebilir. Kaynak işçilerinde görülen bronşit, hırıltılı solunum, bozulmuş pulmoner fonksiyon, kronik obstrüktif akciğer hastalığı, metal duman ateşi, akciğer kanseri, nörotoksisite ve böbrek toksisitesi gibi sağlık sorunları ile kaynak işlemi sırasında açığa çıkan kaynak dumanı maruziyeti arasında güçlü bir ilişki olduğu gözlenmiştir. Bu derleme kapsamında, kaynak işçilerinde kaynak dumanına mesleki maruziyete bağlı olası toksik etkiler kapsamlı olarak değerlendirilecek, kaynak dumanından korunma yöntemleri ve yasal düzenlemeler hakkında bilgi verilecektir. Anah tar Ke li me ler: Kaynak yapma; kaynak dumanı; iş sağlığı; toksisite ABS TRACT The welding process, an easy and fast technique for cutting and joining metals, is widely used by manufacturers and repairers. Millions of people around the world work under unhealthy and insecure conditions in the welding process. Depending on the nature of the work in welding, the welding process creates risks related to the factors such as chemical structure of the welding material, combustion gas, current intensity, arc voltage, welding speed and time, coating substances and paints on the main material, the structure of the electrode used in welding. The main potential hazards in welding are the pollution of the workplace air such as dust, welding gas and fumes, electromagnetic radiation, electricity, noise, fire and explosion, as well as welders are shown to be exposed to crucial toxic metals and gases through welding fumes. General toxic effects of welding fumes may vary depending on the type and concentrations of toxic gases and metals, their exposed levels, and smoking habits. It has been observed that there is a strong relationship between the exposure of welding smoke during welding process and the health problems such as bronchitis, wheezing, impaired pulmonary function, chronic obstructive pulmonary disease, metal smoke fever, lung cancer, neurotoxicity, and renal tox...
