What Makes Welding Fumes & Gases Hazardous?

The quantity of hazardous materials in welding fumes generally depends on 2 major factors. They are the welding process & the type of materials used. According to professionals, welders in NSW, hazardous materials or substances can be classified into 3 categories. They are poisonous or toxic hazardous substances, respiratory damaging substances, & carcinogenic hazardous substances. This blog mainly focuses on these substances.

Poisonous hazardous substances
After reaching a certain concentration, many poisonous hazardous materials may cause several health diseases. Some toxic or poisonous hazardous substances include:

Manganese oxide: Manganese oxide is highly responsible for respiratory system issues, Parkinson’s disease, pneumonia, etc. It also affects nervous system disorder.

Zinc oxide: Zinc oxide may cause fever. The nanoparticles badly affect the lungs. It also causes necrosis.

Copper oxide: Copper oxide may cause nausea, diarrhoea, eye pain & fever. This substance also affects livers & kidneys. 

Nitrogen oxides: Short breath, respiratory system irritation & pulmonary oedema can be caused by nitrogen oxide.

Carbon monoxide: Carbon monoxide is a common toxic substance that causes dizziness, fainting, fatigue, respiratory paralysis, headaches, breathing problems, unconsciousness, cardiac arrest, etc.

Carbon dioxide: Carbon dioxide is highly responsible for several respiratory problems, shortness of breath, headache, dizziness, anxiety, unconsciousness, etc.

Phosgene: Phosgene may cause pulmonary oedema, respiratory failure, irritation, etc.

Respiratory damaging substances
Respiratory systems can be damaged badly by hazardous materials during welding structural steel & other metals. Some major substances responsible for respiratory issues include

Iron oxides: Iron oxides may cause joint disorders, congestive heart failure, diabetes, etc.

Aluminium oxide: Aluminium oxides affect the functional lung tissues directly.

Magnesium oxide: Fever, irrigation, tickle & excessive sweating are caused by magnesium oxide. It affects the lungs badly.

Titanium dioxide: Titanium dioxide directly affects the lungs,
brain, kidneys, liver, heart, & immune system.

Carcinogenic hazardous substances
Last but not the least, carcinogenic hazardous substances can cause malignant tumours in the welder’s body. Common carcinogenic hazardous substances include:

Lead oxide: Lead oxide affects the kidney. It also causes 
gastrointestinal disorders, nausea as well as nerve damage.

Beryllium oxide: Beryllium oxide can cause Chronic pneumonia, metal fine fever, etc.

Cadmium oxide: Cadmium oxide is mainly responsible for mucous membrane irritation & hyperinflation.

Cobalt oxide: Respiratory organ failure can be caused by Cobalt oxide. 

Ozone: Ozone can cause membrane irritation, delayed pulmonary edema, etc.

Hazardous substances or materials in welding fumes are highly dangerous. To avoid these fumes and gases, proper safety precautions and health check-up are essential for every welder, supervisor & inspector.
