easy access.
Oil leaks present a greater hazard on gas turbines than on most other
types of machinery. Care must be taken to minimize the number of places
where leaks can occur, especially in hot areas. However, oil leaks will
occur and one should ensure that provision is made to collect the oil in a
safe location.

Maintenance Records

Once again, gas turbines represent a slightly different problem in terms
of record keeping. Generally much more information is supplied with a
gas turbine than any other type of machine. As the gas turbine is oper-
ated, inspected, and overhauled, a great deal of valuable information be-
comes available. If collected and properly organized, these data will
form the cornerstone of an effective maintenance strategy.
Maintenance records should include a maintenance log of work per-
formed on the turbine and operating data from the machine as well. This
