Where is it advisable to store scrap amalgam?

Storing scrap amalgam under sulfide is advisable due to its ability to mitigate the potential release of toxic metals, primarily mercury, which can be present in amalgam waste. By storing it under sulfide, the mercury is chemically bound and prevented from escaping into the environment, which is critical for maintaining safety in dental practice and compliance with environmental regulations. This method of storage is also generally recognized to minimize health risks associated with exposure to mercury vapors.

In contrast, storing scrap amalgam in a dry container or a glass jar might not adequately contain the mercury, allowing for possible leakage or evaporation into the atmosphere. An open bin would pose the highest risk, as it would leave the amalgam exposed to air and potential contamination or accidental exposure, which is not a safe practice in any clinical setting.
