In the context of HAZWOP, what are 'confined spaces'?

Confined spaces refer to areas that are not designed for continuous human occupancy but have restricted means of entry and exit. These spaces can present significant hazards due to their potential for containing toxic gases, limited oxygen, or the presence of other physical hazards. In the context of hazardous waste operations, understanding confined spaces is crucial because workers may be required to enter these areas to perform tasks related to hazardous waste management. Proper training, safety protocols, and monitoring are essential to ensure the safety of personnel who may need to work in such environments.
