|Isolation competency test
|One of Tarmac’s Golden Rules for safety concerns the safe isolation of equipment. There must be a risk assessment and everything should be executed by a competent person.
In order to demonstrate this competency, a twenty question test was devised to evaluate a person’s understanding of equipment isolation. The nature of the questions relate to twenty different scenarios involving the locking off of machinery or equipment. The candidate is then asked to select the correct option. A score of below 70 per cent represents a failure. The same also applies if the candidate fails a mandatory question – where a person’s life would be endangered if they made the wrong decision.
