What can cause deaths to drop in high-risk environments?

Increased safety training directly addresses the risks present in high-risk environments. When workers receive comprehensive training on safety protocols and hazard recognition, they become more aware of potential dangers. This heightened awareness allows them to make better decisions while working and to respond more effectively in emergency situations. As a result, the likelihood of accidents diminishes, which ultimately leads to a reduction in fatalities. Safety training also promotes a culture of safety within the workplace, empowering employees to take an active role in their own and their coworkers' protection.

In contrast, introducing new hazardous materials would likely increase risk and potential for accidents, eliminating safety regulations would certainly lead to higher danger without safeguards in place, and reducing the number of workers might lessen the immediate potential for accidents but does not address the root causes of danger or improve overall safety practices.
