How it's used
Focuses on serious, often systemic threats rather than minor inconveniences or personal slights. It is frequently used in formal contexts like news reports or official warnings regarding health, safety, or public order. While it can be used in daily conversation, it carries a weight that makes it sound quite grave or authoritative.
Examples
Doing it this way will endanger everyone's safety.
Will these chemicals harm the environment?

Common mistake
Learners often confuse this with 傷害, which is typically used for direct, physical, or emotional injury to a person. 危害 is broader and usually refers to abstract concepts like safety, health, or the environment.
