Ongoing evaluation of operator skills demands a coherent and fixed procedure. It commences with a well-defined expectation of professional capacities and abilities exclusive to each role. It is essential to come up with an exhaustive list of elementary abilities tied to each respective operation an operator is supposed to carry out. These are the practical abilities an operator needs to fulfil their responsibilities, like for example, observing safety rules or making decisions under higher importance and tight deadlines.
Tests should be both practical and theoretical to ascertain ability. Short written tests may prove useful in grasping such formal elements in addition to the procedures. However, safety rules can be better examined through short simulations or job redundancy checklists where one works alongside other operators. At this stage, it is also important to consider the level of effectiveness of the protocols. Regular training sessions for the various aspects should also be conducted for improvement and addressing any residual gaps.
Conducted at regular intervals, in addition to follow up screenings and trainings, competency checks happen. Failure for an operator to pass during the follow up training should trigger an alarm as it could be a sign of widespread maladjustment in the process streams and the standardization of the infrastructure. The operator becomes more reliable with each new set of standards issued, hence the importance of the modern comprehension cycle in upward training.
Emergency Procedures and Pesponse
Steps to Take in Case of Emergencies
