Impressions, appliances, and contaminated dental models sent to dental laboratories must be sealed in an impervious container and labeled 'Biohazard' to signify the potential presence of hazardous biological materials. This practice is crucial for safety and is mandated by OSHA regulations.

Explanation:

Impressions, appliances, and contaminated dental models that are to be sent to dental laboratories must be sealed in an impervious container to prevent the potential spread of infectious diseases. These containers must be clearly labeled as 'Biohazard' prior to shipment from a dental office. The term 'Biohazard' signifies that the contents of the container may contain biological substances that pose a threat to health and safety. In a dental context, these hazardous substances might include saliva, blood, or other potentially infectious materials.

Not only are these procedures crucial for safety, but they are also in accordance to OSHA regulations that mandate the appropriate packaging and labeling of potentially hazardous medical waste. The 'Biohazard' label, usually in bright red with a characteristic symbol, makes it easy for anyone handling these items during transport or at the dental laboratories to recognize the care needed to ensure safety.
