Explanation
The noFlashingHazard
value is the opposite of flashing
— it is used to indicate that the the publisher has
checked the publication for flashing hazards and is sure that none exist.
The value is not an indication that a lack of flashing is a hazard.
The noFlashingHazard
value must never be set together with the
unknown
,
flashing
, or
unknownFlashingHazard
values, as these values conflict.
The noFlashingHazard
value should not be set with the
none
value, as these values are redundant.
