Ceramic fibers can affect human health in various ways depending on their type, exposure levels, and duration of exposure. Inhalation of ceramic fibers can lead to respiratory issues such as lung inflammation and fibrosis. Prolonged exposure may increase the risk of lung diseases, including lung cancer. Some ceramic fibers are classified as potential human carcinogens by organizations like the International Agency for Research on Cancer (IARC). Workers in industries that produce or use ceramic fibers are at a higher risk of exposure and should follow safety protocols, including wearing protective gear and using ventilation systems to minimize health risks.
