The DROPS Calculator provides a common benchmark in the classification of the potential consequences of a dropped object.
One of a number of similar tools, the DROPS Calculator is endorsed by the DROPS Workgroup and recognised by the majority of Operators and Contractors in the global oil and gas sector. While other ‘calculators’ exist, they all follow the same principle – plotting the mass of a dropped object against the distance it falls to determine its possible consequences.
The DROPS Calculator is best employed during planning and risk assessment processes. It will determine the potential severity rating of potential dropped object hazards and help with the risk ranking of appropriate corrective actions and control measures.
