The Single Occupational Risk Assessment Document must be updated:
1° At least once a year in companies with at least eleven employees;
2° Whenever a decision is taken to make any major change to health and safety conditions or working conditions;
3° When additional information relevant to risk assessment is brought to the employer’s attention.
The annual programme for the prevention of occupational risks and the improvement of working conditions or the list of prevention and protection actions mentioned in III of Article L. 4121-3-1 is updated each time the single occupational risk assessment document is updated, if necessary.
