A confined space is an area that is not designed for continuous occupancy and has limited means of entry or exit. These spaces can include tanks, silos, tunnels, and pits. Due to their restricted nature, they can pose significant safety risks, including poor ventilation and the potential for hazardous atmospheres. Working in confined spaces often requires special training and safety measures. Workers must be aware of potential dangers such as toxic gases, low oxygen levels, and the risk of engulfment. Proper procedures, including the use of personal protective equipment (PPE) and monitoring devices, are essential to ensure safety.
