Working in Confined Spaces is a task that carries the risk of asphyxiation, because the work area often has limited air, with an oxygen level below 19.5%, which may cause workers to lose consciousness from a lack of breathable air, or to inhale various toxic gases. In addition, there are many other hazards, such as the danger from flammable chemicals or Explosives, as well as other hazards including electric shock, falling from height, slipping, and so on.
This also includes providing refresher training on working in confined spaces in accordance with the criteria of the law before an employee starts work, or when there is a change of job or a change of confined-space work location.
