What are the hazards of natural wood?
It is commonly thought that artificial wood might be harmful to workers and users due to the chemicals used in its production. However, natural wood is not entirely safe either. Health screenings of workers in the wood industry have shown that even those handling natural wood suffer from a higher rate of conditions like dermatitis and upper respiratory infections compared to other industries.
Natural wood can also pose health risks due to several factors. First, wood dust, especially when it contains more than 10% free silica, can be dangerous. Second, certain bioactive substances found in tropical woods may contain toxic or biologically active compounds, ranging from simple carbohydrates to complex polycyclic compounds. Lastly, noise and vibration from the processing equipment can contribute to long-term health issues.
The effects of processing natural wood on the human body can be quite severe. Direct exposure to harmful substances in the wood can lead to allergic reactions such as dermatitis, eye irritation, conjunctivitis, and irritation of the upper respiratory tract. These can progress into more serious conditions like rhinitis, asthma, and allergic skin diseases.
In addition to these direct effects, there are other concerns related to wood processing. Studies from various countries suggest a higher incidence of cancer among workers in the timber and furniture industries. Although the exact causes are still unclear, researchers have linked this to prolonged exposure to wood dust and other hazardous materials. Some studies in the U.S., Australia, and Sweden have found an increased risk of nasal adenocarcinoma, lung cancer, and bladder cancer among these workers. In the latest carcinogen report by the U.S. Department of Health and Human Services, wood dust was once again classified as a potential cause of nasal and sinus cancer, reinforcing the need for better safety measures in the industry.
