Guida verificata passo dopo passo1
Recognize that mercury is a toxic heavy metal and its spills require special handling due to health and environmental hazards.
Understand that mercury vapor can be harmful if inhaled, so immediate evacuation and notification of a responsible authority (such as an instructor) is necessary.
Avoid using common cleaning methods like sweeping with a broom or using paper towels, as these can spread mercury droplets and increase exposure risk.
Do not dispose of mercury-contaminated materials in regular trash because mercury requires special hazardous waste disposal procedures.
Follow laboratory safety protocols by notifying the instructor or safety personnel immediately and evacuating the area until proper cleanup can be performed.
