A confined space course is a type of training course created to give people the information and abilities they need to perform safely in limited spaces. Restricted spaces are places that are not meant to be occupied continuously but may be accessed for particular tasks like upkeep, repair, or cleaning. Tanks, silos, sewers, and subterranean tunnels are a few examples of restricted areas. Risk assessment, hazard identification, ventilation, gas monitoring, and emergency response protocols are just a few of the subjects covered in the course. It is crucial for those who work in occupations like construction, mining, or manufacturing, which frequently require them to enter small areas.
