Can ceramic fibers cause harm to human health when inhaled or ingested?

Yes, inhaling or ingesting ceramic fibers can potentially be harmful to human health. These fibers, when inhaled, can cause respiratory issues and may lead to diseases such as pneumoconiosis. Prolonged exposure can lead to more severe conditions like lung cancer and mesothelioma. Ingestion of ceramic fibers is less common but can still cause harm, particularly if the fibers are sharp and could cause internal injuries. It's important to handle ceramic fibers with care and use appropriate protective equipment to minimize the risk of exposure.
