We have a sign that says:

Some exhibits in this area contain magnets or produce magnetic fields.
 These exhibits are identified with a [warning sign with a magnet, see

We actively try to identify the difference between a risk and a
hazard.  A risk you can plan for and mitigate, a hazard is hidden and
can sneak up and bite you.  A tall jungle gym is risky.  A almost
broken broken hand rail is a hazard:
