Can ceramic fibers be inhaled or ingested by humans?

Ceramic fibers can potentially be inhaled or ingested by humans, especially in environments where they are being manufactured, processed, or used. Inhalation of these fibers can lead to respiratory issues, and ingestion can cause gastrointestinal problems. It is important to handle ceramic fibers with caution and use appropriate protective measures, such as wearing masks and gloves, to minimize the risk of exposure.
