A close partnership, collaboration and communication between Occupational Health and Industrial Hygiene is key. The outcome of the IH risk assessment should form the bases of the medical surveillance program. Work related health complaints reported at Occupational Health should be investigated by the IH department. Close communication at different levels is mandatory. In the first part of the presentation, the structure and partnership at Johnson and Johnson Corporate Level will be shared. In the second part, examples of collaboration at a J and J site (Janssen Campus Belgium) will be highlighted. Strong collaboration creates benefits on Corporate, Site, Departmental and Personal level.
