Final answer:
Changes in elevation should be marked to prevent tripping hazards.
Step-by-step explanation:
True.
To prevent tripping hazards, changes in elevation should be marked. This is especially important in public spaces, workplaces, and environments where people with disabilities or visual impairments may be present. By marking changes in elevation, such as steps, ramps, or sudden drops, individuals can be alerted to potential hazards and take appropriate precautions to avoid accidents.
For example, in a school setting, if there is a step or a change in elevation in a hallway, it should be clearly marked with contrasting colors or tactile cues so that students with disabilities or those who may not pay close attention to their surroundings can easily identify the change and navigate it safely.
