Oxy-fuel can be immensely useful for cutting and welding, but it is important to keep in mind that they are serious pieces of equipment that can be dangerous if you misuse them. This is why it is vital that you learn more about the various safety procedures you need to abide by to stay out of trouble when using an oxy-fuel cutter.
Not only this, but once you are abreast of the necessary safety procedures, you can actually work faster. This is because you won’t be distracted by the fear of injury or calamity due to a lack of knowledge or training. Instead, you can confidently use the oxy-fuel cutter while giving it the respect it deserves.
You should start by understanding the main hazards caused by oxy-fuel cutters and the fire safety tips that can keep you and those around you safe from injury if the worst happens.
Here is everything you need to know about oxy-fuel welding and cutting safety procedures:
When you are first learning about oxy-fuel safety procedures, knowing where to begin can be tricky. These are complicated machines that can be intimidating if you don’t know how to treat them correctly, so it is best to start in the most logical place - with the most common hazards of oxy-fuel welding and cutting.
Firstly, there is the risk of fire - which is typically caused by sparks, heat, the hot metal as you cut or weld, or contact with the flame itself.
This is why it is necessary to wear fireproof clothing - such as gloves, an overall or apron, and a mask. While it is unlikely that you will come into direct contact with the flame, for instance, you should be sure to stand as far back from the process as possible. This will massively reduce the chances of burns or other serious injuries.
There is also the chance of ignition when there are backfires, gas leaks, or flashbacks from the cutter, as well as toxic fumes caused by the cutting or welding process. To prevent the latter, make sure you use a ventilated area.
If the torch backfires, turn off the oxygen and acetylene cylinder valves and the torch valves. A flashback arrestor can also help prevent flames from reaching the regulator.
It would be best if you also were wary of what you are cutting or welding. Metals that once contained toxic or combustible materials, as well as oils and grease, should be treated with the utmost caution and cleaned beforehand.
Lastly, while oxy-fuel cutters are easy to transport, that doesn’t mean they are light, so be careful when carrying oxygen cylinders and acetylene cylinders between two locations.
Fire presents arguably the most pertinent hazard when using fuel gas cutters. The potent combination of oxygen and fuel makes for an effective cutter, but it can be dangerous if you are negligent with it.
To help reduce the chances of fire-related injury or damage, you should be sure to weld and cut in a safe location that is equipped for high levels of heat. This includes removing any potentially combustible materials which could present a hazard - such as wood, paper, textiles, plastics, or certain liquids.
It may also mean checking that particular walls or surfaces won’t melt or combust when you light the torch.
If you can’t move these objects or materials, then you should ensure that they are covered or guarded against the exposed flame as much as possible - or move the location altogether.
It is also a good idea to start purging the hoses before and after using a cutter to prevent any flammable or explosive gas mixtures from emanating from the torch and to stay vigilant of fire for a 30 minute period afterwards.
