स्पष्टीकरण:

  • आर्क वेल्डिंग हे 200 nm (नॅनोमीटर) ते 1,400 nm (किंवा 0.2 ते 1.4 µm, मायक्रोमीटर) - तरंगलांबीच्या विस्तृत श्रेणीवर प्रारण देतात.
  • यामध्ये अतिनील (UV) विकिरण (200 ते 400 nm), दृश्यमान प्रकाश (400 ते 700 nm) आणि अवरक्त (IR) विकिरण (700 ते 1,400 nm) यांचा समावेश होतो.
  • हेच कारण आहे की डोळ्यांचे अतिनील आणि अवरक्त किरणांपासून संरक्षण करणे आवश्यक आहे.
  • वेल्डरला संभाव्य धोक्यांपासून संरक्षण करण्यासाठी पुरेशी उपाययोजना केली जाते तेव्हा आर्क वेल्डिंग हा एक सुरक्षित व्यवसाय असतो.
    • संरक्षक कपडे
    • कानात मफ किंवा प्लग घालणे 
    • त्वचेच्या संरक्षणासाठी शिरस्त्राण आणि हातातील मुख संरक्षक 
    • डोळ्यांच्या संरक्षणासाठी गडद पटलाचा चष्मा
