El Centro College-Intruder Lock-down. Go to nearest room and lock-down. If not at campus STAY AWAY for your own safety DCCCD Alerts
Final assessment
All 25 reads agree the source is present; it names El Centro College and DCCCD Alerts.
Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.
Final assessment
All 25 reads agree the hazard is present; it names an intruder prompting a lockdown.
What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.
Final assessment
All 25 reads agree the location is present, referencing the El Centro College campus and nearest room.
Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.
Final assessment
All 25 reads agree guidance is present; it instructs people to go to the nearest room and lock down or stay away.
The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.
Final assessment
All 25 reads agree time is absent; no clock time, date, or recency word appears.
When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.
Final assessment
Present by a 21 to 4 majority: it reports an intruder lockdown and tells people to stay away for your own safety, pairing protective guidance with an explicit safety danger.
What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
