Miners, archaeologists, and professional divers as also space researchers, scientists, and investors risk their lives during certain life-threatening or potentially dangerous scientific experiments they conduct. Scientists have endowed mankind with brilliant discoveries, sometimes risking their health and even life. Take the example of Marie Curie, who died of overexposure to radiation, as the adverse effects of radiation were not known when she was working with radioactive elements. This underlines the importance of understanding occupational hazards so that correct safety measures are taken.
