Quality Control Measures In Iron Ore Ppt

  • Control Measures in Hazard Assessment -

    Think of a control measure as an action aimed to eliminate a hazard completely. If the hazard you've identified can't be eliminated, follow the hierarchy of controls to select the next-best control to mitigate the risk of an accident, incident, injury, or near-miss in the laboratory. Your risk assessment may reveal that you will need a temporary control measure until you can put a better and
