Redefining Confined Space Safety: A Case Study SPE

Confined Space work is one of the most challenging aspects of a maintenance project. Accidents can occur if potential hazards such as fire, elevated temperatures, gas, fumes, vapor, lack of oxygen or limitations to movement are not properly managed. This considerable level of danger calls for extra safety measures that consist of a safety watch
