Candidates should be provided with formal training relevant to the different types of PTW for which they are to be authorized (eg hot work, work at height, electrical work). This should include:
• The different risks that could be present;
• How those risks should be controlled;
• Specific details of the relevant PTW forms;
• Where to get expert advice, if in doubt.
Comprehension should be formally assessed, eg through a written comprehension test. Only those who demonstrate comprehension may pass on to the next step.
