Is Welding Bad For Your Health?

A welder must endure harmful noise pollution, metal fumes, vibration, and dust exposure on a constant basis. Is welding bad for your health, then? Yes, if they don’t take safety precautions, the welders run a lot of health risks.

Welding has alarming long-term effects. Small discomforts brought on by welding eventually add up to serious health problems. Welders can however safeguard their health by taking a few easy precautions and being aware.

With any luck, this article has provided you with some information about the potential causes and solutions to welder health problems.

How Hazardous Is Welding, Exactly?

Welding is just a process for joining two metal pieces together, right? How risky can it possibly be? Multiple energy sources, such as: are used during the permanent bonding of metal to metal process. gas flames, electric arcs, electric resistance, lasers, electron beams, friction, molten metal baths and ultrasound. When the material has liquefied, it is joined together with or without the addition of more filler materials. Actually, welding is a fairly risky process. Every time a welder reports for work, they are exposed to potentially fatal risks. A real and present danger is the potential for electrocution, fire and explosion, burns, electric shock, vision damage, inhalation of poisonous gases and fumes, and exposure to strong ultraviolet radiation. They must be aware of the risks associated with their work environment, such as performing their activity in a confined space, at a height, or even underwater, in addition to the immediate dangers that welding poses.

Studies And Research

The American Society of Safety Engineers (ASSE), one organization that has compiled studies and research results, lists both short-term and long-term effects of exposure to welding fumes. The short-term side effects are frequently bronchitis, pneumonitis (lung inflammation), encephalopathy (a syndrome that causes brain dysfunction), nausea, eye, nose, ear, throat, and chest irritations. Metal fume fever is a different short-term side effect with flu-like symptoms that last for 24 to 48 hours.

The Society cautions against working with metal that contains cadmium because it can be fatal, but some welding fumes are more lethal than others.

The National Institute for Occupational Safety and Health (NIOSH) is actively involved in studies involving fumes that contain manganese (commonly added to carbon steel to make it strong and hard), and these studies have discovered that Parkinson’s disease (or something with the same symptoms) is caused by exposure to manganese fumes.

Other typical long-term health effects of welding exposure, according to the ASSE, include pulmonary infection and heart disease, respiratory illness, lung and throat cancer, stomach problems, kidney disease, and a variety of neurological issues.

A health and safety fact sheet from the American Federation of State, County, and Municipal Employees (AFSCME) lists numerous welding risks that welders should be aware of. Additional safety and health fact sheets, totaling more than 40, are available from the American Welding Society (AWS). These fact sheets are more in-depth and concentrate on each of the areas of concern.

Health Issues Due To Welding

Welding can cause a lot of discomforts and diseases. They can be roughly divided into a few types. These are discussed below –

Respiratory Issues

This includes conditions like bronchitis, pneumonia, asthma, cancer, metal fume fever, throat and lung irritation, and temporary reductions in lung function.

In 2003, NIOSH published a study on the medical literature relating to welding-related health problems. Many respiratory problems that workers experience are either directly or indirectly related to welding fumes and the environment, according to the article on the “Health Effects of Welding.”

Those who weld are susceptible to lung infections, which frequently result in serious or even fatal pneumonia. Although 40 to 50 welders are admitted to hospitals each year due to an infection, modern medical advancements typically assist patients in recovering from the condition. And two of those incidents result in death. It is therefore a serious issue to think about.

Approximately nine workers experience asthma each year as a result of factors brought on by the workplace. They even endure such excruciating suffering. Although a recent study from the HSE found that welding fumes do not directly cause asthma, they also advised workers to limit fumes as much as they can to protect themselves.

Nickel exposure (6.03E-03 to 2.12E-02) and hexavalent chromium exposure together account for almost 90% of the risk of upper-band cancer.

The main carcinogenic gases produced by welding stainless steel are fumes. However, other welding fumes are also categorized as potentially carcinogenic on a global scale.

After welding, some welders experience flu-like symptoms. It’s referred to as metal fume fever. At the start of their workweek, this typically occurs. Despite the fact that it typically has short-term effects.

The human body is not quite suited to many of the fine metals or other particles found in welding gas or fumes. Dry throat, constricted chest, and coughing fits are brought on by these. Due to the ozone gas that spreads throughout the air during TIG welding, this typically occurs. Unusual lung fluid is a known effect of ozone. As a result, prolonged exposure to these gases or fumes reduces lung capacity. (Information about why welders drink milk.)

Hand-arm Vibration Caused Health Issues

Welding is related to needle scaling and grinding. These put people at risk for shaking hands or arms. Carpal tunnel syndrome (CTS) and hand-arm vibration syndrome (HAVS) may result from this.

Early in their careers, some welders may start showing symptoms of these conditions. Although HAVS is preventable, the harm is unfortunately irreparable.

Musculoskeletal Disorder (msd) Due To Welding

It can be harmful to a person’s health to frequently twist or sit in uncomfortable positions while welding. According to a press release from the Washington University School of Medicine, there is also a strong correlation between Parkinson’s disease and the manganese found in welding fumes.

Additionally, welding fumes have been linked in one NIOSH article to damage to the nervous system. The fumes contain the potentially carcinogenic metals nickel, manganese, and chromium. However, there isn’t enough research to support the claim that fumes can lead to such severe health problems.

The Provision and Use of Work Equipment Regulations of 1998 recommend that employers take worker safety into account when selecting equipment for them in order to reduce health risks that they may encounter.

A fact sheet on welding hazards is available from the American Federation of State, County, and Municipal Employees (AFSCME), which lists the health and safety risks related to metal cutting, brazing, soldering, and welding.

An AFSCME fact sheet claims that welding smoke is a dangerous concoction of tiny particles and gases. zinc, chromium, asbestos, nickel, arsenic, beryllium, manganese, phosgene, silica cadmium, acrolein, nitrogen oxides, fluorine compounds, cobalt,  carbon monoxide, copper, ozone, lead, selenium are found in welding fumes which are extremely toxic. Filter or base materials, metal coatings or paints applied over the welding electrode, chemical reactions caused by UV light and heat, shielding gases, etc. all produce these fumes.

A study found that stooped posture, constipation, and fatigue were responsible for about 50% of the manganese poisoning cases.

Health Problems Due To Noise

Unhealthy noise levels are produced by electric arc welding. The welding environment and the associated tasks are noisy, though TIG welding is an exception in this instance.

Eye Problems

25% of all welding-related side effects are eye-related. Most of these eye injuries can be avoided, though. Nearly 95% of welders with eye injuries typically return to work within a week.  More than 50% of returns happen within two days. To completely avoid these problems, they should continue to follow the safety protocol, though.

Short-term Effects

The most common short-term effects of welding fumes are coughing, nose, eye, and chest irritation, shortness of breath, edema, bronchitis, appetite loss, lung inflammation (pneumonitis), nausea, vomiting, cramps, and so on.

Long-term Effects

There have been hundreds of research projects conducted in an effort to pinpoint the chronic, lifelong health effects of welding exposure; the National Institutes of Health (NIH) US National Library of Medicine alone has 554 studies listed. Numerous are particular, referring to one or more related conditions or diseases. Many welders face dangers every day, so some people think of solutions to help them avoid those risks.

Like the ASSE guidelines, the AFSCME fact sheet is more general but still provides an overview of the issue. It informs readers that smokers and welders are particularly at risk for laryngeal and urinary tract cancers as well as an increased risk of developing lung cancer. The causes cited include the well-known cancer-causing substances present in metal and various other elements, as well as the extremely high concentrations of toxic substances present in welding “smoke,” in particular (in alphabetical order):

  • Arsenic, which occurs in many minerals and is used to strengthen many copper alloys
  • Beryllium, which is often added to strengthen alloys of copper, aluminum, iron, and nickel
  • Cadmium, which has historically been added to metals to make them less corrosive – but which is being used less and less due to its known toxicity
  • Chromium, which is added to iron and carbon steel to increase the metal’s rust resistance
  • Nickel, a hard, ductile metal that is resistant to corrosion

Although many welders experience chronic lung conditions like asthma, bronchitis, reduced lung function, emphysema, pneumonia, and diseases like pneumoconiosis, siderosis, and silicosis, which frequently occur after silica exposure, welders may not get cancer. These conditions are all related to the dust that welders breathe.

Additionally, research has linked welding to heart disease, hearing loss, chronic gastritis, gastoduodentitis (which causes the stomach to become inflamed), small intestine and stomach ulcers, skin conditions, heart disease, and loss of hearing. Kidney damage has been found to be particularly dangerous for people who have been exposed to nickel and chromium.

Welders exhibit a lower sperm count (and quality) than men in other occupations, which has been shown to pose a problem with regard to reproductive risks. It appears that those who weld stainless steel are more dangerous.

Welders are undoubtedly at risk of experiencing a variety of terrible long-term health effects, but these risks can be significantly reduced if the right safety precautions are taken.

How Can The Health Risks Of Welding Be Lessened?

Avoid Gases And Fumes

After breathing in gases and fumes, you may occasionally experience specific warning signs. When welding on galvanized metal, for instance, if you breathe enough zinc fumes, you could later develop metal fume fever. Night sweats, chills, and stomach pain are among the symptoms. Or, after breathing in certain fumes, you might experience headaches or shortness of breath.

In contrast, there are a lot of gases and fumes that you might breathe in over the course of your career that don’t have any obvious warning signs. Even if air testing reveals that these fume exposures are within the current occupational regulatory limits, those limits are merely a reference point for comparing the airborne concentration. They shouldn’t be viewed as a 100% safe exposure level.

The metals in welding fumes are mixed together. For instance, manganese, whose impact on health has recently attracted a lot of attention, is present in mild steel, which is primarily made of iron. Iron, nickel, and chromium are all components of stainless steel. The health effects of every substance could vary.

Typically, the nose filters and gathers most of the smoke, fumes, and grinding dust that welding machines produce. However, some weld fume particles can enter the lungs through the nose, sinus cavity, throat, and down the back of the throat because they are so small. The majority of people rarely even notice irritations. You start to show symptoms after years of breathing welding fumes. Although the symptoms may be mild, such as breathing heavily after climbing a flight of stairs, the underlying issues may be much more serious.

The risks posed by gases and fumes can be significantly reduced by being aware of your surroundings and taking a few easy precautions. To protect yourself, follow these recommendations:

  • Don’t let the welding fumes touch your face.
  • Standing to the side will help the breeze push the fumes away from your face if there is a natural breeze blowing through the building. Don’t obstruct the airflow.
  • When there isn’t a natural breeze in the building, whenever it is possible, use a cooling fan to remove fumes. You must keep in mind that being too close to a large fan will cause the shield gas surrounding the arc to be removed. The fan should be moved until you feel a very slight breeze. While the breeze won’t keep you cool, it will help the smoke and fumes escape.
  • When possible, weld on pristine metal. Remove coatings and paints from the area that will be welded because they burn and smolder and produce unpleasant odors and gases.
  • Be sure to properly utilize local exhaust ventilation systems. Place the hood close to the weld and arrange your workspace so that the ventilation controls can function as intended.
  • Wear a respirator to protect your lungs if you are unable to capture the fumes with an exhaust ventilation system or cooling fan.

Protect Your Hearing

As strange as it may sound, breathing in fumes could damage your hearing. There is a clear link between specific chemicals and damage to the audio-nerve, according to numerous health studies. As an illustration, breathing large amounts of carbon monoxide gas affects how much oxygen enters the blood. Auditory nerve cells become stressed and more vulnerable to damage if the oxygen level in the blood that supplies them is decreased.

The noise welding produces poses a more overt threat to hearing. Many welders ignore noise as a health hazard. The same people who might wear earplugs or earmuffs when grinding metal will forego the protection when welding simply because it doesn’t seem loud—at least not to the point of being painful. However, welding is loud enough to slightly damage nerve cells, and over time, little scratches here and there add up.

Auditory nerve cells are irreversibly harmed by even moderately loud noise, such as that produced by welding. Both damaged and new cells are unable to repair themselves. Hearing loss is the long-term effect. Put on ear protection today to avoid auditory nerve damage. As with saving money, it’s never too late to start, but the earlier you start, the better off you’ll be in the long run.

Use Your Head, Not Your Back

The body can become worn out after years of constant kneeling or lifting. Older welders frequently experience chronic pain in their shoulders, knee joints, and backs.

When you’re young, working in an awkward position might seem quicker and easier than transferring the task to a table and working at a comfortable height. Even if you decide to move the component, it might be more convenient to manually lift a heavy object to a bench than to use a mechanical hoist.

Similar to winning the battle but losing the war, both strategies are used. The squatting and lifting may save you some time, and you may not even experience any pain at the time, but over time, the repetitive motions can wear you out. Consider your working environment carefully. Don’t stay in one place for too long, use lifts, ask for assistance when moving heavy objects, and make every effort to maintain your comfort level. This doesn’t mean you’re a weakling. It’s a straightforward admission that the choices you make today will affect how you will feel in the future.

Conclusion

Clearly, welding poses some health risks. However, following safety procedures can greatly reduce the risk to one’s health. While most of these consequences can be avoided, some are fairly inevitable.

So it is safe to answer the question, “Is welding bad for your health?”as- yes, it is risky only if you are not careful. However, it is generally safe if you follow the correct instructions.
