The practice of occupational hygiene in its broadest concept is essential to health preservation in the Royal Navy. In the environment in a ship, where the seaman works and lives, the usual hazards of noise, fume, dust, toxic chemicals and radiation pose special problems in control because of confined space, ventilation difficulties, climatic extremes and operational requirements. All levels of command are involved in determination of hazards, implementation of action to prevent them and supervision and training in safe practice, with the Medical Department in an advisory and supervisory role. Expertise is spread across the board with central supporting services to investigate problems in depth and carry out research in matters of particular naval importance.
