Arc Welding Safety Checklist

Daily Checks that should be performed during arc welding operations

Welding Machine Checks

1          Ensure power supply is disconnected prior to performing these checks  

2          Check for damages to switch or socket 

3          Ensure that the correct size plug is fitted for the rated current and duty cycle of the welding machines     

4          Check the power supply cable is of correct rating          

5          Check if the power supply cable plug is damaged         

6          Check for cuts, burns, abrasions or other damage to the supply cable insulation 

7          Ensure that the supply cable is located away from welding cables and connections. 
8          Ensure supply cable is securely anchored on to welding machines and plug       

9          Inspect the welding machine for damages to the cabinet, power switches, indicator lights and controls    

10         Ensure that the welding cable connections to the welding machine are in good condition, contact surfaces are clean and properly tightened  

11         Examine welding cable and earth cables for cuts , burns, damaged insulation or any other damage that may expose live wires          

12         Welding and earth cable should be of similar length and rated for the maximum current carrying capacity of the welding operation         

13         Check that both male and female connections are fully insulated with clean contact surfaces and all fittings are tightened properly with non conductors exposed    
14         Check that the electrode holder is good condition and is fully insulated. It should be rated for the maximum current rating and the duty cycle of the welding activity.            

15         Ensure that the earth clamp is securely connected to the earth cable and the job close to the welding machine     

16         Ensure that the welding set is connected to the right kind of input power supply. Single or three phase. Ensure a qualified electrician connects the welding power source 

Personal Protective Equipment

1          Ensure that the welder wears the right kind of clothing. Synthetic clothing is prohibited.   

2          Clothing is clean and free from dirt grease, and oil Avoid rolling up sleeves and pants
Collar should be buttoned up    

3          Ensure high top leather shoes with steel toes are worn and pants not tugged inside the boots     
4          Ensure welding apron is worn if required
5          Check leather welding gloves are used by welders
6          Ensure that the surroundings and the welders clothing is dry
7          Ensure welding helmets and shields are being used with the right shade no
(For SMAW if the current range is 60~160 Amps the recommended shade no is 12)         

8          Ensure use of ear muffs or ear plugs

Fire Fumes & Gases

1          Ensure that the work surroundings are clean and there is no combustible / flammable material in the vicinity         

2          Ensure fire resistant shield is placed between the work and the material likely to be damaged by the welding sparks           

3          If welding is being carried above ground or off a ladder ensure that there is no flammable / combustible material underneath the ladder   

4          If welding is carried above ground or off a ladder / scaffolding ensure welder and helpers have a safety harness and umbilical cord anchored to a safe point.

5          Ensure that the area is free of fine dust if the combustible or volatile nature of the dust is not known do not authorize welding operation         

6          Check the surfaces of the work to be welded and make sure that the work is free of any flammable coatings       

7          Ensure location of nearest fire hydrant and extinguishers is known if there are no fire fighting equipment ensure fire hoses, sand/water buckets, and portable fire extinguishers are positioned in the vicinity of the welding operation 

8          If welding operation is being carried out with in 35 feet of any flammable material a trained Fire Sentry/Guard/watch is to be positioned    
9          If a fire sentry is used he should not leave the welding site 30 mins post welding operation         
10         Ensure welding area is adequately ventilated and the cross ventilation is not blocked by partitions, equipment and other structural material 

11         Ensure forced ventilation is available if welding in confined space
12         Prior to commencing welding in confined space ensure that the space is free from combustible vapours, toxic fumes and necessary certificates indicating suitability to commence welding have been obtained
