What should be the first step when handling a broken mercury-containing lamp?

1. Sweep up the pieces immediately

2. Seal the pieces in a plastic bag

3. Notify local hazardous waste authorities

4. Store it in the refrigerator to prevent evaporation

The correct answer is: Seal the pieces in a plastic bag

The first step when handling a broken mercury-containing lamp is to seal the pieces in a plastic bag. This is important because mercury is a hazardous substance and can vaporize at room temperature, presenting a risk to both health and the environment. By sealing the broken pieces in a plastic bag, you contain the hazardous material, thereby minimizing exposure to mercury vapors and making it safer to transport the debris for proper disposal. Taking immediate action to seal the broken lamp prevents further spreading of the mercury and ensures that proper protocols are followed during the cleanup process. It's also crucial to follow local regulations on disposal to ensure that the hazardous waste is handled correctly. This step lays the groundwork for the safe handling and disposal of mercury-containing materials, protecting both individuals and the environment from potential harm.
