What action is discouraged concerning the storage of mercury-containing lamps at home?

1. Keeping them in a locked container

2. Storing them in areas with extreme temperatures

3. Labeling them as hazardous waste

4. Using clear plastic bins for visibility

The correct answer is: Storing them in areas with extreme temperatures

Storing mercury-containing lamps in areas with extreme temperatures is discouraged due to the potential risk of the lamps breaking or leaking hazardous materials. Extreme temperatures can affect the integrity of the bulbs and can lead to the release of mercury, which poses serious health and environmental risks. Proper storage is essential to ensure safety and to prevent contamination. Safe storage practices generally include keeping the lamps in a stable environment, avoiding areas that could experience extreme heat or cold, and ensuring that the storage method protects them from breaking. Keeping the lamps in a locked container, labeling them as hazardous waste, or using clear plastic bins for visibility are practices that promote safety and proper handling of these items.
