What is often a consequence of improper hazardous material handling?

Improper handling of hazardous materials frequently leads to significant health risks to both humans and the environment. When hazardous substances are not managed correctly, they can be accidentally released into the air, water, or soil, causing contamination. This exposure can lead to a variety of health issues for individuals, including chemical poisoning, respiratory problems, and long-term diseases such as cancer. Additionally, ecosystems can be severely impacted, as wildlife and plant life may be harmed by pollutants and toxins.

In contrast, the other options do not accurately reflect the outcomes of improper hazardous material handling. For instance, improper handling typically increases waste generation rather than reducing it. Regulatory compliance is also likely to decrease, as lack of proper handling often results in violations of environmental laws. Finally, energy costs are usually unrelated to hazardous material management, and improper handling typically does not lead to lower energy costs. Therefore, the most direct and relevant consequence of improper hazardous material handling is indeed the health risks posed to humans and the environment.
