This course outlines critical safety practices for working in confined spaces, such as tanks, silos, and pipelines, focusing on hazard identification (toxic gases, oxygen deficiency, engulfment risks), mandatory safety measures (entry permits, ventilation, gas testing, and isolation procedures), proper use of personal protective equipment (PPE), emergency response planning (rescue protocols and equipment), and the roles of personnel (entrants, attendants, supervisors, and rescuers) to prevent accidents and fatalities in high-risk environments, in compliance with Singapore’s Workplace Safety and Health Council standards.
