Welding Fumes and Indoor Ventilation
Welding fumes are a silent killer when welding without adequate ventilation and respiratory protection. Of course, hobbyists and DIY welders won't inhale as much fumes as professional welders who work in fabrication and other industries, but everyone should ensure minimal fume exposure.
The International Agency for Research on Cancer (IARC) classified welding fumes as carcinogenic to humans (Group 1) in 2017. Besides being cancerogenic, welding fumes can cause multiple chronic and acute illnesses, including respiratory, heart, kidney, and nervous system damage.

However, managing welding fumes is possible. Professional welding shops and other businesses that conduct welding services must meet permissible exposure limits (PELs) as defined by the Occupational Safety and Health Administration (OSHA). This is especially the case when welding highly toxic materials like stainless steel, lead, beryllium, or cadmium-plated steel.
While some materials are more hazardous to weld, all welding fumes pose a danger to your health, including those originating from regular mild steel. There are no safe welding fumes.
Welding Fumes

Welding causes the base metal and the filler metals (stick rods, TIG wires, MIG wires, or FCAW wires) to melt, along with any filler metal fluxes. Burning these materials causes tiny hazardous metal particles to evaporate in the air in what we call welding fumes. The fume content includes manganese, fluorides, various metal oxides, and other dangerous chemicals. Once inhaled, they can cause harm in multiple ways.
The best way to protect yourself is to weld outside and use an adequate welding respirator. But, if you need to weld indoors, it's highly recommended to use local ventilation systems like a fume extractor. At the very least, you should ensure a strong draft to displace the welding fumes and reduce their concentration. We recommend using a high-quality welding respirator or a PAPR system for welding indoors.

Confined Spaces
Welding in confined spaces poses a significant hazard. Unless you are a professional welder certified for working in confined spaces, you should definitely avoid such welding jobs.

Confined spaces can be pressure vessels, vaults, pits, manholes, ductwork, pipelines, tanks, silos, tunnels, and similar spaces where there is just about enough room for one person to enter.
If you weld inside a confined area, you could quickly lose available oxygen as welding fumes and the shielding gas would engulf you. As a result, the likelihood of suffocation becomes exponentially higher.
However, confined spaces don't have to be as "industrial." Simply crawling under a piece of machinery or under any sort of structure to weld can put you in danger. This could even happen in your garage or your home. It's crucial to consider the availability of fresh air before you start welding in any restricted space scenario.
Confined spaces can also lead to getting stuck, burned, electrified, or physically harmed by the machinery or structural elements in the confined space. This is why OSHA requires professionals to have a permit to work in a confined space .

What Other Professionals Are Working in the Same Area?
If you are working on-site with multiple other trade professionals, that could significantly amplify the chances of you or them getting injured.
Multi-trade professional environments are typical for a construction site, but you could experience them elsewhere. For example, you could be working in manufacturing, but an electrical team could be scheduled for maintenance near your welding booth.
Whenever there are multiple trade teams on site, things are bound to get a bit messy. There are many tools being moved around, materials being prepared and handled, machinery being operated, scaffolding, and people moving around. Needless to say, welding in such environments can lead to injuries.

The first thing to do is get informed on what other trades will work in the same area as you, what type of work they'll perform, and when they'll do it. This will help you organize your work so that your or their equipment won't cause a bottleneck in the area or lead to injuries. If possible, ask the site manager to conduct a brief meeting in the morning before everyone starts their work. A short conversation about who does what goes a long way in preventing accidents in a dynamic work environment.
It's also very important to know which materials are used by other trades. For example, if you start welding soon after someone used chlorinated hydrocarbon solvents in the nearby area, you could get seriously harmed or even die. The welding arc causes the chlorinated hydrocarbon compounds to become a highly hazardous phosgene gas, which can poison you after just a single inhalation. This compound destroys lung tissue, and it's nearly impossible to be treated in the hospital. So, being aware of whether someone is using any degreasing agents, solvents, paints, and other chemicals that contain chlorinated hydrocarbons is important. That's why a morning brief can help prevent such incidents from occurring. This is just one example; multi-trade sites can easily lead to more complex issues where people can get hurt.

Fire Hazards - The Not So Obvious Dangers
It's no secret that welding is a fire hazard, but not all welding-related fires start in a predictable manner. If they did, there wouldn't be many welding fires at all. Welders would see it coming and prevent it. Did you know molten slag can stay smoldering for hours before eventually causing combustible materials to catch fire? That's one of the ways fires can start after everyone has left the shop, a garage, or any other work area.
Here's a fire safety checklist that can help you prevent fires in your work area:
-
Keep a suitable fire extinguisher nearby. Remember that welding combustible metals like magnesium and titanium requires class D fire extinguishers. Other extinguishers cannot put down metal fires.
-
Fire watchers should be present at professional welding jobs. But, if you are welding as a hobbyist, it's recommended to have another person keep a check on things while you are under the hood, as you might not be able to see if something starts burning.
-
Inspect the area for combustible materials before welding. Remove all flammable and combustible materials from the welding area to at least 35 feet from the welding arc. This includes cardboard boxes, paper bags, food, dry leaves, dust, plastic, cotton, etc.
-
Ensure fire exit routes are clear. You don't want to get trapped with fire and for the firefighters not to be able to approach your home/shop.
-
Cover all combustible floors with non-flammable material.
-
Don't leave the welding area immediately after welding. Keep watch and inspect any crevices for signs of fire, like smoking and smoldering. Fires can break out hours after welding, so inspect everything thoroughly.
-
You might need a hot work permit . Welding in a potentially hazardous area can require obtaining a hot work permit, depending on your local laws and regulations.
-
ALWAYS ensure you follow all fire codes and regulations, especially those regarding pressurized flammable gases.

Noise and Its Hazards
While welding fumes are a silent killer, noise is a loud one! Noise can have a negative effect on your hearing ability, stress levels, and situational awareness. Indirectly, noise can contribute to your ability to react swiftly in critical situations. Imagine someone yelling for help or to warn others in the work area, yet no one hears them in time due to excessive noise levels.
On the less extreme side of things, noise can lead to noise-induced hearing loss (NIHL) and cause ringing in the ears (tinnitus).
The best way to control noise is to use quiet equipment and processes. Old AC stick welding buzzboxes produce a lot of noise, while modern inverter-based welders are much quieter. YesWelder welding machines are not loud, because we use a very efficient fan cooling system.
Another way to protect yourself is to use ear protection. This requires a calculated approach because earmuffs and earplugs might also prevent hearing alarms or other people.

Tripping Hazards
Cables, lines, and gas hoses. You can't weld without them, but you certainly can trip on them!
Not only will you have a power cable for your welder and lines for the torch and the ground clamp in the area, but you may also need extension cords, angle grinders, and other tools. The problem is exacerbated if there are other workers in the area working with power tools.

Tripping on a cable can potentially be life-threatening. You could fall down the stairs, through an opening, or even hit your head on the wall or power equipment in the area. While most tripping accidents aren't as extreme, those that are can get you seriously injured.
When you are under the welding hood, your ability to avoid falls decreases, especially if you don't have much experience under the hood. So, as your awareness lessens, tripping on a cable can have you fall flat without much chance of grabbing onto something as you are going down. This becomes especially dangerous if you are working near an edge or stairs.
That's why it's important to have a clear working area. If you must have some cables on the ground, keep them in mind as you move around the welded piece. Always be aware of the cable positions and move carefully when under the hood. It's recommended to lift the hood to scan the area before moving away from it.
YesWelder welding helmets have a low shade level when not welding, a large view area, and high optical clarity. This may help you get a better sense of your environment, especially when using our helmets with side windows . However, it's not recommended to rely on a helmet alone. You should practice awareness and occasionally lift the hood to inspect the environment, especially if other people are working around you.

Compressed Gases - Cylinders or Rockets?
A compressed cylinder is just one valve break away from becoming a rocket. So, if your MIG/TIG shielding gas bottle were to fall and break the valve on top, it would start its journey to Mars! While it won't beat the ambitions of Elon Musk, it will wreck your garage/shop and possibly injure you or someone else.
Compressed gases pose a significant hazard. It's imperative to know OSHA compressed gas safety rules , even if you aren't welding professionally. Compressed gas tanks need to be handled properly for safe use.

Here are some tips for safe compressed tank handling:
-
Keep the valve protection caps in place when moving or transporting the tanks. Only remove the cap once the tank is secured and ready for use. This will help prevent the valve from breaking in case of a fall.
-
Close the main valve when done using the tank. This will prolong the life of the valve by preventing corrosion and contamination.
-
Always open the main valve slowly and stand away from the outlet.
-
Never use a cylinder to ground an electric circuit.
-
Don't tamper with the cylinder or attempt any DIY repairs. If you notice that something is off with the bottle, call your supplier for instructions.
-
Never place a cylinder near extreme sources of temperature. High temperatures can cause explosions of pressurized bottles.
-
Don't lift the cylinders by their caps. Only move cylinders according to the supplier's instructions.

Ensuring the Safety of Those Around You
Almost all welding hazards you can experience can also harm others in the area. Welding fumes, UV/IR arc radiation, electrical hazards, fire, and physical harm all extend to everyone in the near vicinity. So, it's critical to ensure their safety as well.
Start with the welding arc protection. While you wear a welding helmet, others around you should not be arc flashed. Use welding screens or take the welding work somewhere isolated. For example, if you weld at home, use your garage or the backyard if no one else has access to it. If you are a hobbyist welder, let your family know if you are welding to prevent anyone from accidentally stumbling upon the welding arc and getting flashed.
Use welding screens for a safe welding zone.

If you are working in a welding/metalworking/auto shop, ensure others are isolated from the welding arc by welding screens. Likewise, it's critical to capture and filter the welding fumes with a fume extractor and other mechanical ventilation methods in a professional environment.
Warning Signs and Labels
Warning signs and labels are an excellent way to signal others that they are entering the welding area. This can help others anticipate a welding arc, sparks, and welding fume in the area. Likewise, welding signs indicate high-voltage equipment or engine-driven welding equipment in the area and help the observer prepare accordingly.
Signs can also prohibit uncertified or unpermitted personnel in the welding area or prohibit welding activities in certain areas. For example, if your shop has areas with combustible materials or compressed gases, you can place a sign that forbids welding in the area so your employees don't accidentally start welding there.
OSHA's "Right to Know" hazard communication standard requires employers to communicate hazards associated with the workplace to employees, which includes warning signs and labels. So, all professional shops must abide by this code. All welding and non-welding staff must be warned of all hazardous fumes, arc radiation, physical injuries, electric shocks, and burns that they may experience in the welding area. Of course, this standard doesn't just deal with warning signs and labels, but they are a part of it. Workers must also receive proper training on understanding the hazards, prevention, and detection.

Conclusion
There are many hazards in the welding industry, but if you set your welding area right, you will minimize them. This was a brief overview of multiple welding dangers you can experience in the work space, whether you are a professional or a DIY welder. It's highly recommended to continuously learn about welding hazards. No one knows everything, but through continuous research, education, and discussion with others, we can all avoid more dangers in our work.
Hazards can often be neglected and ignored until it's too late and people get hurt. At that point, they become immediately apparent. But, if you notice things like cable clutter on the ground, excessive fumes, or combustible materials in the welding area, you can prevent an incident, and save your or someone else's life by sharing what you learned or acting upon it.
We highly recommend staying vigilant in the welding industry. Health is irreplaceable, and welding is dangerous. However, following safety protocols makes welding far less hazardous, giving you the ability to be a part of this phenomenal trade for your entire life. Many older welders are healthy even if they've spent thousands of hours under the hood, and the primary reason why is adherence to safety protocols.
