When must the hepatitis B vaccination be offered to employees?

The hepatitis B vaccination must be made available within 10 working days of initial assignment, after appropriate training has been completed. Thus, arranging for the administration of the first dose of the series must be done at a time which will enable this schedule to be met. Only persons who render first aid only as a collateral duty, responding solely to injuries resulting from workplace incidents, generally at the location where the incident occurred would not have to be offered the pre-exposure hepatitis B vaccination (OSHA would consider this a de minimus violation — a technical violation carrying no penalties).
