Oxy Fuel Welding Safety Checklist

Safety Checks prior to use of an Oxy fuel welding equipment

Equipment Pre Start Checks

1          Check cylinders are secured and in upright position and secured in a trolley        

2          Check cylinder labelling. Check there is no mechanical damage. Check condition of the seat and ensure it is clean and dry      

3          Inspect the valve for damage. If the valve appears to be damaged, “Do Not Open”.  
4          Crack cylinder valve prior to fitting gauges, do not cover with hand.       

5          Check type, rating and condition. When fitting regulators to cylinders ensure they are not contaminated with oil or grease.

6          Flash Back Arrestor should be fitted on both the regulator and blow pipe ends of the hose. Ensure FBA’s are operational.      

7          Check correct hoses are fitted for Oxygen (Blue), Acetylene (Red), or LPG (Orange).
8          Check hoses for damage particularly at junctions to fittings
9          Ensure the blow pipe is in good condition, the body is true, valves open and close fully, threads and seats are in good condition

10         Check the tip condition, seats are in good condition, face is flat and clean, hoses are open and free of contamination, tip is of right size and type for the job in hand. Set regulator pressure to suit tip and plate thickness         

11         Ensure purging is carried out prior to use. Keep your head and face away from cylinder valve outlet when opening the cylinder valve.  

12         Checks for leaks between the cylinder valve and the regulator and other fittings and hoses. Eliminate all leaks prior to commencement of operation    

13         Ensure proper friction lighters are used to light up the torch avoid matches, cigarettes etc           
14         On completion of operation close cylinder valves and depressurise blowpipe     

15         Ensure empty and full cylinders are segregated. Different types of gases are stored separately and are identifiable. All cylinders should be stored at a safe distance form sparks, flammable, combustible material. 

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 Gas Welding  if the Plate thickness upto 12 mm the recommended shade no is 6 and above 12 mm the recommended shade no is 8) 

(For Gas Cutting if the Plate thickness upto 25 mm the recommended shade no is 4 , upto 150 mm the recommended shade no is 5 and above 150 the recommended shade no is 6)
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/cutting is being carried above ground or off a ladder ensure that there is no flammable / combustible material underneath the ladder   

4          If welding/cutting 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/cutting 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/cutting 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/cutting in confined space
12         Prior to commencing welding/cutting 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
