Code N.B.C stands for which of the following?

• A. Nuclear, Biological, Chemical Hazard
• B. Nuclear, Biological, Chemical Event
• C. Nuclear, Biological, Chemical Spill
• D. Nuclear, Biological, Chemical Contamination

Answer: (C)

NBC is emergency shorthand for Nuclear, Biological, Chemical. In a code context, choosing “spill” signals that there has been a release or leakage of those substances, which triggers specific response actions like containment, decontamination, and protective measures. The other terms describe the risk or outcome rather than the actual incident type: a hazard is the danger itself, an event is too generic to specify the kind of incident, and contamination refers to what may result from exposure rather than the act of release. So, identifying the incident as a spill best communicates that there has been a release of NBC materials that responders need to manage.
