ST. PAUL, MN – You’re casually going about your day, maybe shopping or relaxing on a plane, and suddenly, you hear a strange phrase or code over the intercom. It sounds like a random series of words, but in certain situations, it’s a signal that something serious is happening. From police emergencies to hidden bomb threats, these codes can mean life or death. Here are secret phrases you might hear, and what they really mean.

Police and Aviation Codes That Mean Trouble

10-33
You probably recognize the police code 10-4 as meaning “okay,” but 10-33? That’s something much more urgent. It signals that there’s an emergency in progress, and police need immediate backup. Different police departments may have varying codes, but 10-33 generally alerts other officers to a critical situation unfolding.

7500
When you’re flying high in the sky, you never want to hear the number 7500. This code is used to indicate that a plane has been hijacked. Because the meaning of this code is so well-known, many airlines have discreet systems in place, like buttons in the cockpit, to send this alert without drawing attention. Once the transponder is switched to 7500, air traffic control will ask the pilot to confirm the emergency.

Code 10
The phrase “Code 10” can actually mean a few different things. In hospitals, it can signal mass casualties or a significant threat. However, in some retail settings, like grocery stores or big-box retailers, a “Code 10” can mean the cashier is suspicious of your credit card and needs to verify its legitimacy. And if you happen to be shopping at Walmart? Don’t worry—Code 10 just means there’s a dry spill that needs cleaning up.

Codes You’ll Hear in Hospitals and Public Spaces

Code Adam
A term that was born out of tragedy, Code Adam is used to alert staff to a missing child. It originated at Walmart in 1994 following the abduction of Adam Walsh, and has since spread to other stores and public places like hospitals, museums, and malls. In 2003, Congress even mandated that all federal buildings adopt Code Adam procedures in the event of a child abduction.

Code Blue
If you’re in a hospital and hear “Code Blue,” it’s time to get serious. This emergency code is used to indicate that someone is experiencing cardiac arrest and requires immediate medical attention. Not every hospital uses the same codes, but Code Blue is one of the more common alerts for a critical heart-related emergency.

Code Silver
In a hospital, a “Code Silver” is a signal that there is a violent situation taking place. Whether it’s a person with a weapon or a hostage situation, this code is used to trigger a lockdown and notify staff to respond quickly. It’s not something you ever want to hear when you’re visiting a hospital, whether you’re a patient or a doctor.

Doctor Firestone
No, Doctor Firestone isn’t a real physician—but you might hear this name called out in the event of a fire at a hospital. This is the discreet way hospital staff alert each other to the presence of a fire without causing widespread panic. It’s just one of the many ways hospitals have developed secret codes to handle emergencies while keeping the situation as contained as possible.

Maritime and Transportation Alerts You Need to Know

Code Bravo
If you’re at the airport and hear a “Code Bravo,” it’s time to stay alert. This code indicates a bomb threat or another security breach at the airport. Security might shout the phrase over a loudspeaker to cause people to freeze in place while officials work to locate the threat. It’s a strategic way to control the situation quickly.

Code Oscar
On ships, a “Code Oscar” means there’s a man overboard. It’s a clear, direct alert to everyone on board that someone has fallen off the vessel, and immediate action is needed to rescue them.

Echo, Echo, Echo
No, this isn’t someone playing around with a microphone on a cruise ship. If you hear “Echo, Echo, Echo” over the intercom, it means there’s a serious collision risk or high winds that could affect the ship’s safety. It’s an alert that signals an urgent situation where the crew needs to respond quickly.

Inspector Sands
If you’re traveling in the UK, “Inspector Sands” might sound like a normal name—but it’s actually a secret code used by transportation officials. When you hear it over the public address system, it’s a discreet way to signal that there’s either a fire or bomb scare in a train station or the London Underground. It allows officials to take quick action without alarming the public.

Operation Rising Star
Hearing this phrase on a plane isn’t a good sign. It means someone has passed away during the flight. While “Operation Rising Star” is used to indicate a death, other phrases like “Operation Bright Star” are used to signal a medical emergency. It’s just one example of how airlines have developed codes to handle serious in-flight incidents with discretion.

Pan-Pan
When you hear “Pan-Pan” on the radio, it’s an international distress signal. While not as urgent as “Mayday” (which is used when a plane is about to crash), Pan-Pan signals a serious but non-life-threatening emergency. This could be anything from a boat taking on water to a plane having engine trouble. It means that the situation needs attention but isn’t immediately catastrophic.

Time Check
It might sound like something you’d hear at the start of a new hour, but when a “time check” is announced over a store’s loudspeaker, it actually means there’s a bomb threat. Shoppers familiar with the code should evacuate immediately, while store employees must try to locate the bomb. It’s an unsettling reminder of how everyday phrases can hide a serious danger.

…and Now You Know!

Now that you know the hidden meanings behind these everyday codes, it’s clear that a random-sounding phrase could be a serious signal for help. From emergency codes on planes to urgent hospital alerts, these phrases are designed to get quick action when lives are at stake. It’s always better to know the code than to be caught off guard if you ever hear them in real life. Stay alert and stay safe.
