A school must communicate a chemical leak immediately and also preserve proof of safety instructions. Which communication combination is best?

Answer and explanation

Correct answer: Siren, public announcement, and written digital instructions

The governing concept is choosing complementary communication methods according to purpose. A siren and public announcement provide rapid, wide-reaching audio warning, while written digital instructions create a durable record that can be checked later. A poster may be missed, a private message reaches too few people, and a next-day notice is too late. Thus, option A best satisfies both urgency and evidence.
