Authorities have officially identified the previously unknown material found at the Henderson Main Post Office earlier this week as mercury. This conclusion follows detailed analysis and testing conducted by specialized hazardous materials (HazMat) teams who responded promptly after the initial alert. The discovery triggered an immediate evacuation of the facility and the implementation of stringent safety protocols to protect postal employees and the surrounding community from potential mercury exposure.

Key response measures initiated include:

• Evacuating all personnel within a 100-meter perimeter of the contamination site
• Deploying advanced mercury containment equipment to isolate the substance
• Conducting continuous air quality assessments to monitor mercury vapor concentrations
• Collaborating with local health authorities to evaluate exposure risks and provide medical support
• Performing thorough decontamination and post-cleanup verification to ensure safety
