(1)
Beginning of the potential injury refers to the occurrence of the injury and not to its manifestation
(2)
There is potential for the event to be developed over a period of time not usually sufficient for manual corrective action.
(3)
There is potential for the event to be developed over a period of time usually sufficient for manual corrective action.
(4)
There is potential for the event to be developed in an non-
specified period not greater than that provided in “prompt”.
In this alarm system, there is no change in priority of the alarm condition and in the event of more than one alarm simultaneously:
•
Alarm messages of high priority will be displayed alternately, following the priority described in Table 36.
•
In the absence of high-priority alarms, the medium-priority alarms will be displayed alternately.
The alarm messages are displayed as soon as detected the alarm condition; so there is no delay to display the messages.

Note
•
It is recommended that the operator complies with the maximum distance of 1m to properly visualization and
Identification of visual alarms; however, alarm signals are perceptible to a distance of 4 m from the equipment.
•
In order to identify the occurrence of an alarm, the operator should preferably be 1 meter from the front of
the equipment at an angle of 30 ° with the horizontal axis in the center of the monitor's viewing plane.
•
Sound pressure levels of auditory alarm signals that are lower than ambient levels may prevent operator
recognition of alarm conditions.
