Whenever deviation from this code is contemplated, such deviation must be clearly described and limited in the operations manual or authorised by the contractor for specific operations. An additional HIRA that specifically covers the deviations must be performed and recorded, containing the following aspects:
| • | Diving and working practice planned |
| • | How the practice deviates from this code |
| • | Specific reason(s) for the deviation |
| • | Which specific hazards are introduced because of the deviation |
| • | How these specific hazards are addressed to control and mitigate the risk |
