Danger areas11
Without prejudice to the preceding requirements of these Regulations, every employer shall ensure that—
a
where a workplace contains an area in which, owing to the nature of the work, there is a risk of any person at work—
i
falling a distance; or
ii
being struck by a falling object,
which is liable to cause personal injury, the workplace is so far as is reasonably practicable equipped with devices preventing unauthorised persons from entering such area; and
b
such area is clearly indicated.
