Approximately how many deaths and injuries occur each year in confined spaces?

The choice indicating that hundreds of deaths and injuries occur each year in confined spaces is supported by statistics and reports from various organizations that monitor workplace safety. Confined spaces are particularly hazardous due to factors such as limited access, potential exposure to toxic substances, and the risk of physical hazards, which can lead to serious incidents.

The Occupational Safety and Health Administration (OSHA) and other safety organizations have noted that workers in confined spaces face significant risks, resulting in numerous fatalities and injuries annually. This number reflects the critical need for proper training, safety protocols, and regulatory compliance to prevent accidents in these environments.

The other options, suggesting dozens, thousands, or less than ten, do not accurately represent the documented risks associated with confined spaces and underestimate the serious nature of the hazards involved. This underscores the importance of awareness and safety measures when working in such environments.
