Accessible Publishing Knowledge Base

noFlashingHazard

Explanation

The noFlashingHazard value is the opposite of flashing — it indicates 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.
