Information

Assessment Details

Review operator knowledge about equipment. Does the operator know how the equipment is fit for use (booth &brushes)? Does the operator know how to recognise faults? What does the operator do if the equipment appears to be faulty? Are brushes and containers clean and in good condition? Are ESD controls in use? Does the operator verify the varnish type before use? Are the materials stored in safe conditions? Are all containers marked with the material type for safety purposes? Is the operator clearly understand the safety hazards withe the materials and understand how to treat an accident?

Does the operator understand and use the technical specifications? Does the operator understand the work instructions? Verify that the operator can access the technical specification in the system. Verify that they know how to confirm that the specification selected is correct. Ask the operator to explain some key steps of the specification to ensure that they can understand the details and requirements. Record competence level. Record details of the sample reviewed. Record details of the sample checked and comments from the operator.
Does the operator understand the work instructions? Verify that the operator can access the work instructions in the system.
