Does Welding Cause Lung Disease?

I have been a welder for over 8 years now, and I've noticed that my breathing has become more difficult and I cough more often. Does welding cause lung disease?

Dear John:

There are many dangers welders should be aware of. The hazards, however, depend on such factors as:

welding method

the composition of the welding rod

the filler and base metals

the metal coatings

ventilation during welding activities

Welding should always take place in a well ventilated area to allow the toxic fumes and gases to escape. Gases, such as argon, displace oxygen, causing death.

Toxic Metals

The following toxic metals may also cause health problems:

Stainless Steel - Stainless steel is composed of nickel and chromium, both of which can cause cancer. Nickel has been known to cause asthma, and chromium can cause sinus problems. In extreme cases, chromium can cause holes to develop between the nostrils inside the nose.

Mild and Carbon Steel - Both types of these materials contain manganese, which has been found to cause Parkinson's disease.

Zinc - Zinc, which is found in galvanized metal and paint, can cause metal fume fever. People exposed to metal fume fever have symptoms of flu that can last for several hours or even days after exposure.

Lead - Lead can be found in paint. It can cause headaches, muscle soreness, nausea, cramping, irritability, loss of memory, anemia, and may also damage the kidneys and nervous system.

Cadmium - Cadmium is found in some paints and fillers. It has been known to cause cancer and damage to the kidneys.

Toxic Gases

It is very important that welders be aware of their surroundings during welding activities. Be sure to weld in areas away from chlorinated solvents. A poisonous gas, called phosgene, can cause fluid to accumulate in the lungs. This fluid accumulation can cause a "drowning" affect, leading to death.

During welding activities, gases are produced. These gases are inhaled and can cause damage to your lungs and airways. The following gases can be dangerous health hazards:

Carbon monoxide

Ozone

Nitrogen oxides

How to Protect Yourself

Weld in ventilated areas only

Remove paints, solvents, and residues before welding

Use the safest welding method possible

Use low-fume welding rods when possible

Use local-exhaust ventilation and keep exhaust hood openings 4 to 6 inches from the fume source

Use air blowers to blow fumes away from you

Keep your face as far away from the welding plume as possible

Use a respirator when possible - especially when ventilation is inadequate

Follow OSHA guidelines for proper welding safety
