unsafe

This term carries a heavy sense of imminent risk or structural failure. It suggests a state where the protective barriers or standards have been breached, leaving a person exposed to physical harm. It is often used in official reports or warnings to signal that a situation has crossed a threshold from cautious to hazardous.

While dangerous implies a general threat, unsafe often points to a specific lack of security or a failure of a safety mechanism. It describes a condition of instability, whether that is a rickety ladder or a volatile social environment, where the primary concern is the absence of protection.
