Which of the following is a man-made hazard?

A man-made hazard is typically associated with human activities or industrial impacts that can pose risks to safety or health. Methamphetamine labs fall under this category because they are directly established and operated by individuals, creating environmental dangers such as toxic chemical exposure, explosion risks, and contamination of the surroundings. These labs are products of human action, making them distinct from natural hazards like loose rocks, high altitude, and heavy rain, which are naturally occurring phenomena that can pose their own risks but are not a result of human intervention. Understanding the implications of man-made hazards is crucial for search and rescue operations, as it can significantly affect the safety and strategy of rescues in affected areas.
