Failure effect is an undesired consequence of a failure mode. Failure effects may be categorized as follows:

1 Injuries or damage to personnel or to the public.

2 Damage to the environment.

3 Damage to the system where the failure occurred.

4 Material or financial loss.

5 Interruptions of the system operation (e.g. loss of production, cancelled or delayed transport means, interruptions of electric or water supply, interruption of computer/telephone network service.)

A failure mode may lead to many different failure effects, on the item where the failure occurred, and on other items. Failure effects are classified as local effects, next higher effects, and end effects. These effects are illustrated in Example 3.13.
