8. 

Do

9. 

Do

 use protective screens or barriers to protect from

     flash and glare. The intense light associated with arc
     welding can cause damage to the retina of the eye, while
     infrared radiation may damage to the cornea and result
    in the formation of cataracts. 

    Invisible ultraviolet light (UV) from the arc can cause
   "

arc eye

" or "

welder's flash

" after even a brief 

    exposure (less than one minute). The symptoms of arc
    eye usually occur many hours after exposure to UV light,
    and include 

a feeling of sand or grit in the eye,

    blurred vision, intense pain, tearing, burning, and
    headache

   The arc can reflect off surrounding materials and burn 
   co-workers who work nearby. About half of welder's flash
   injuries occur in co-workers who are not welding. Welders
   and cutters who continually work around ultra violet 
   radiation without proper protection can suffer 

permanent

   eye damage

10. 

Do

wear welding goggles or suitable eye protection

     when working around a welding arc.

   Exposure to ultraviolet light can also cause 

skin burns

   similar to sunburn, and increase the welder's risk of 

skin

   cancer

.

11. 

Do

wear gloves and protective clothing to prevent

burns from hot surfaces and from UV exposure.

12. 

Do

 keep your head out of welding fumes. Do not

     breathe fumes.

13. 

Do

 use a respirator if ventilation is not good.

14. 

Do

 read Material Safety Data Sheets (MSDS) and the

     manufacturer’s instructions for metals, consumables,
     solvents etc.
