When using ceramic fiber wadding board in buildings, it is crucial to follow safety precautions to protect workers and ensure structural integrity. First, ensure that the board is handled with protective gloves to prevent skin contact with sharp edges and potential fiber irritation. Respiratory protection, such as masks, should be worn to avoid inhalation of dust particles. Additionally, ensure that the board is installed in accordance with manufacturer guidelines to maintain its insulating properties and structural strength. Always check for any signs of damage or wear before use, and never use boards that show signs of degradation. Finally, proper ventilation should be maintained during installation to reduce the risk of respiratory issues and to ensure a safe working environment.
