Construction workers are always surrounded by enormous of hazards in the work site. Many of these hazards are temporary or localized, and avoiding them is not a difficult task for workers. However, some of these hazards occur every day. Ultra-Violate radiation (UVR), which has wavelength between approximately 180 NM to 400 NM, is a continuous hazard that can be affects almost everyone working outdoors. Today Australia is considering overexposure to UVR is a public health issue because many outdoors worker including construction workers are exposed to the extreme UVR most of the day from first day of building the project until the last day. Also, UVR is strongly associated with serious diseases that significantly damage some parts of the workers? …show more content…
There are several kinds of skin cancer caused by UVR like melanoma (MSC), and Basal cell carcinomas?(BCC), Squamous?cell carcinomas?(SCC) are general types of non-melanoma (NMSC). Melanoma is the most serious and common skin cancer among young people, which accounts for most skin cancer deaths in the U.S. while non-melanoma diseases could lead to serious issues if they have been neglected, and not treated urgently because they can spread to other part of the body like bones, and cause new serious diseases. According to The Department of Health and Human Services around 9,000 people yearly dying from Melanoma, and around 63,000 people are suffering from the same disease in the U.S. UVR is the main cause of non-Melanoma diseases, and it is responsible for 65% for Melanoma diseases in the U.S, knowing that the main source of UVR of these illnesses is the sun radiation (Armstrong, B.K., and A. Kricker, …show more content…
body that can be damaged because of UVR is the eye. Overexposure to UVR contributes to many hazards to the eye like photo keratitis, photo conjunctivitis, Pterygium, Pinguecula, and cataracts. Photokeratitis and Photoconjunctivitis are kinds of eye inflammation, and usually do not impact the eye health in the long term; however, being surrounded by very reflective surfaces can cause blindness (observatory.com, Page 1). This hazard is associated with using arc welders insufficiently. Pterygium and Pinguecula are damaging the eyes by growing tissues from the witness to cover the eyes (observatory.com, Page 1), and the most common hazard is Cataracts, which is the weakness of the lens? transparency, the dominant cause of blindness in the world (Andrew and Catherine, 2013, Page
