In the event of an unforeseen event requiring a one-off modification to the work organisation initially defined, the employer may ask the worker to deviate from the maximum pressures authorised by his hyperbaric fitness certificate, subject to implementing the necessary safety measures as defined in 3° of Article R. 4461-7.
He shall record this intervention in the individual hyperbaric logbook of the worker concerned.
This worker, who accepts this intervention, may not be led to exceed the following maximum relative pressure values:
1° For class I: 4,000 hectopascals;
2° For class II: 6,000 hectopascals.
Refusal may not constitute misconduct on the part of the employee leading to disciplinary action.
