Chapter 12- PROPULSION STEAM TURBINES 



services such as heating, air conditioning, and 

 compressed air systems. Failure ofany of these 

 services will affect a ship's ability to fulfill 

 its primary objective, either directly by reducing 

 its power, or indirectly by creating conditions 

 which lower personnel morale and efficiency. A 

 secondary objective— which contributes consid- 

 erably to the successful accomplishment of the 

 first— is the minimization of personnel casual- 

 ties and of secondary damage to vital machinery. 

 The details on specific casualties are beyond 

 the scope of this manual. Detailed information 

 on casualty control can be obtained from the 

 Engineering Casualty Control Manual, the Dam- 

 age Control Book, the Ship's Organization Book, 

 and the Damage Control Bills. These publica- 



tions may vary on different ships, but in all 

 cases they give the organization and the proce- 

 dures to be followed in case of engineering 

 casualties, damage to the ship, and other emer- 

 gency conditions. 



The basic factors influencing the effective- 

 ness of engineering casualty control are much 

 broader than the immediate actions taken at the 

 time of the casualty. Engineering casualty con- 

 trol reaches its peak efficiency by a combination 

 of sound design, careful inspection, thorough 

 plant maintenance (including preventive mainte- 

 nance), and effective personnel organization and 

 training. CASUALTY PREVENTION IS THE 

 MOST EFFECTIVE FORM OF CASUALTY 

 CONTROL.
