According to the Building Code, what type of label must tempered spandrel glass have?

Tempered spandrel glass must have a removable paper label according to the Building Code to ensure that information regarding its strength and safety is conveyed during the installation process. This type of label typically provides details about the glass type, manufacturer, and certification that indicates it meets safety standards. The removable nature of the label allows contractors and builders to easily identify the glass while it is in transit and before installation, ensuring compliance with regulatory requirements. This helps to maintain a clear record of the materials used, which is crucial for safety evaluations and future inspections.

The other options do not align with the specific requirements set forth by the Building Code regarding tempered spandrel glass labeling standards. A permanent label would not be necessary during the installation phase, and plastic labels may not adequately convey the required information compared to the crispness and clarity of paper labels. Moreover, a lack of a required label could compromise safety and accountability, which is the essence of building code regulations.
