Labor protection measures for arc welding of labour protection glasses

Different harmful factors need to be protected by different measures.

1. harm and protection of arc welding

(1) the harm of arc welding to human body: arc radiation mainly includes infrared, ultraviolet and visible light. Arc radiation affects the human body, causing acute or chronic damage to the tissues in the body.

UV mainly causes damage to skin and eyes. Eyes exposed to ultraviolet radiation can cause electro-optic ophthalmitis, manifested as eye pain, grit, tears, fear of wind, headache, dizziness, fever and other symptoms; skin exposed to ultraviolet radiation will be red, tender, black, peeling. Ultraviolet radiation has a destructive and fading effect on fiber fabrics.

The visible light of welding arc is ten thousand times larger than that of human being. After being irradiated, the eyes are painful and can not see clearly. It is forbidden to look directly at the arc welding in the distance, especially when the arc is struck. It is forbidden to watch the welding arc near the protective masks.

(2) Measures to prevent arc radiation: (1) In order to prevent arc radiation and splash scald, labor insurance articles, work clothes, shoes, hats and gloves should be used in accordance with the relevant regulations issued by the labor department. (2) when welding is carried out, a mask with an absorbing filter lens must be used. The filter should be selected according to the current intensity. Hand-held or helmet-mounted protective masks should be portable, non-flammable, non-conductive, non-thermal, and non-leaking. (3) In order to protect the eyes of other workers in the welding site, protective screens are usually installed in the fixed place of small pieces of welding. When welding on site, the welder should remind the people around him to avoid the arc light when starting the arc, so as to avoid the arc damage to the eyes. (4) When working at night, there should be good lighting, or the brightness of the light will change repeatedly and cause eye fatigue of welders. (5) when it causes electric ophthalmia, it can go to the hospital for medical treatment. You can also use milk (human or milk) for eye drops, 1 drops per 1-2min, 4-5 times
