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 areas like tanks, silos, tunnels, and pits. They often have restricted ventilation, which can lead to hazardous conditions due to the accumulation of toxic gases or lack of oxygen. Working in a confined space can pose serious risks to safety. Workers must be trained to recognize these hazards and follow safety protocols. Proper equipment, such as respirators and harnesses, is essential to ensure the safety of individuals entering these environments.
