How it's used

This term is formal and typically reserved for serious, high-stakes situations involving life or death. It is rarely used in casual conversation to describe everyday safety, where words like 安全 are far more common. You will most frequently encounter it in news reports, official statements, or dramatic storytelling.

Examples

This matter concerns the safety of many people, we cannot act recklessly.

Common phrases

to take safety into account

Common mistake

Learners often use this word in everyday contexts where it sounds overly dramatic or stiff. If you are talking about personal safety in a routine way, such as walking home at night, stick to 安全 instead.
