SAFETY PRECAUTIONS 

These safety  precautions are for protection of  safety and health.  Failure to 

follow these  guidelines may result  in serious injury or death.  Be careful to 

read and follow all cautions and warnings. Protect yourself and others.

  

Welding and cutting  processes produce high levels of ultraviolet (UV) radiation that 
can cause severe skin burn and damage. There are other potential hazards involved 
with welding such as severe burns and respiratory related illnesses.  Therefore ob-
serve the following to minimize potential accidents and injury: 
 
Use appropriate safety glasses with wrap around shields while in the work area, even 

under welding helmets to protect your eyes from flying sparks and debris. When chip-
ping slag or grinding, goggles and face shields may be required. 

 

When welding or cutting, always use an approved shielding device, with the correct 

shade of filter installed.  Always use a welding helmet in good condition.  Discard any 
broken or cracked filters or helmets. Using broken or cracked filters or helmets can 
cause severe eye injury and burn. Filter shades of no less than shade 5 for cutting 
and no less than shade 9 for welding are highly recommended.  Shades greater than 9 
may be required for high amperage welds. Keep filter lenses clean and clear for maxi-
mum visibility.  It is also advisable to consult with your eye doctor should you wear 
contacts for corrective vision before you wear them while welding. 

 
Do not allow personnel to watch or observe the welding or cutting operation unless 
fully protected by a filter screen, protective curtains or equivalent protective equip-
ment. If no protection is available, exclude them from the work area.  Even brief expo-
sure to the rays from the welding arc can  damage unprotected eyes. 
 
Always wear hearing protection because welding and cutting can be extremely noisy.  
Ear protection is necessary to prevent hearing loss.  Even prolonged low levels of 

noise has been known to create long term hearing damage.  Hearing protection also 
further protects against hot sparks and debris from entering the ear canal and doing 
harm. 
 
Always wear personal protective clothing.  Flame proof clothing is required at all 
times.  Sparks and hot metal can lodge in pockets, hems and cuffs. Make sure loose 
clothing is tucked in neatly. Leather aprons and jackets are recommended.  Suitable 

welding jackets  and coats may be purchased made from fire proof material from 
welding supply stores. Discard any burned or frayed clothing. Keep clothing away 
from oil, grease and flammable liquids. 
 
Leather boots or steel toed leather boots with rubber bottoms are required for ade-
quate foot protection.  Canvas, polyester and other man made materials often found 
in shoes will either burn or melt.  Rubber or other non conductive soles are necessary 

to help protect from electrical shock. 
 
Flame proof and insulated gauntlet gloves are required whether welding or cutting or 
handling metal.   Simple work gloves for the garden or chore work are not sufficient.  
Gauntlet type welding gloves are available from your local welding supply companies.  
Never attempt to weld with out gloves.  Welding with out gloves can result in serious 
burns and electrical shock.  If your hand  or body parts comes into contact with the 

arc of a plasma cutter or welder, instant and serious burns will occur.  Proper hand 
protection is required at all times when working with welding or cutting machines!
