Trapped: The Real Cost of a Failed Exit
On a September morning in 1991, workers at a chicken processing plant in Hamlet, North Carolina, found themselves in a real-life horror story. A fire broke out, and thick, toxic smoke filled the air. They ran for the exits, but the doors wouldn't open. They were locked.
Management had chained the doors shut to prevent employee theft. In a matter of minutes, those doors transformed from simple exits into deadly traps. Panicked workers pushed against them, but it was no use. Twenty-five people died that day, and 55 were injured. Investigators later confirmed a heartbreaking truth: nearly everyone could have escaped if the emergency egress routes had been clear and the doors had worked.
This tragedy is a stark reminder of a simple, terrifying fact. A door is supposed to be a way out. When it fails, it becomes a barrier, and the consequences can be catastrophic. The hardware on a door isn't just a detail; it's a critical life-safety system.
More Than 30 Years Later, Same Problem, New Technology
You might think a disaster like the Hamlet fire is a relic of the past. But the core problem—a door that fails in a crisis—is still with us. In September 2025, the U.S. National Highway Traffic Safety Administration (NHTSA) began investigating thousands of Tesla vehicles. Why? Their electronic door handles could stop working if the car's battery voltage dropped.
People reported being trapped inside their own cars because the electronic system failed. While a car is not a building, the principle is the same. In an emergency, whether it’s a fire or a car crash, you need to get out instantly. If the exit isn't simple and reliable, technology can create new kinds of traps. This highlights why emergency egress is a non-negotiable part of modern design and fire safety.
What is Emergency Egress and Why is it Your First Line of Defense?
When an emergency strikes—a fire, a gas leak, or a structural collapse—every second counts. People don't have minutes to figure out how to open a door; they have seconds. A delay of just 10-15 seconds at an exit can be the difference between life and death.
This is why building and fire safety codes are so strict about how exit doors must work. These rules, found in regulations like the BC Building Code (BCBC) and the National Building Code – Alberta Edition (NBC-AE), are written to ensure anyone, regardless of age or ability, can escape quickly and safely under extreme stress.
The goal is to make exiting a building simple, intuitive, and foolproof.
The Unsung Heroes of Fire Safety: Door Hardware
Let's break down the specific hardware that keeps you safe. What do these technical terms really mean for you?
Panic Hardware: The Lifesaver for Crowds
Have you ever seen a wide bar across an exit door at a movie theater, school, or stadium?
That’s panic hardware.
What it is: A device, often called a crash bar or touch bar, that spans the width of a door.
How it works: You just push against the bar, and the door unlatches. It’s designed for a single, simple motion.
Why it's critical: In a panic, a crowd can surge toward an exit. Panic hardware allows the door to be opened by the force of people pushing against it, preventing a deadly crush. You don't need to find a knob, turn a lever, or use a key.
Codes require this hardware in places with large groups of people because it is the most effective way to ensure a fast and orderly evacuation.
Fail-Safe vs. Fail-Secure: What Happens When the Power Goes Out?
Many modern buildings use electronic locks for security. But what happens during a power outage, a common event in an emergency? That's where the difference between fail-safe and fail-secure becomes a matter of life or death.
Fail-Safe: When power is cut, the lock unlocks. This is the standard for emergency egress routes. If the fire alarm goes off or the building loses power, the doors will automatically be openable.
Fail-Secure: When power is cut, the lock stays locked. This is used for high-security areas where keeping people out is the priority, but it should never be used on a primary exit door in a path of egress.
Building codes demand that electronic locks on exit paths be fail-safe. Safety must always come before security.
Understanding Canadian Building Codes for Egress
In Canada, both British Columbia and Alberta have strict rules to prevent tragedies like the Hamlet fire. While the specific sections may differ, the principles are the same.
Key Requirements in BC and Alberta Building Codes:
One Simple Motion: Exit doors must open with a single action. You should not have to turn a knob and then pull a lever, for example.
No Keys, No Special Knowledge: You must be able to open an exit door from the inside without needing a key, a special tool, or any prior knowledge.
Release on Alarm: All electromagnetic locks (mag-locks) and electric strikes must be tied to the building’s fire alarm system. The moment an alarm sounds, these locks must release.
Clear Signage: If an electronic lock is used, there must be a sign that clearly states how it works, such as "EMERGENCY EXIT - UNLOCKS WITH FIRE ALARM."
These rules are not just suggestions; they are legally enforceable standards designed to save lives.
Common Mistakes That Compromise Emergency Egress
Despite clear building codes, dangerous mistakes are still common. They often happen due to a lack of awareness or a misguided attempt to improve security.
Watch out for these red flags:
Chains or Padlocks: Chaining an exit door shut, even "just for tonight," is incredibly dangerous and illegal.
Blocked Exits: Storing boxes, furniture, or equipment in front of an exit door turns a safe path into an obstacle course.
Wrong Type of Lock: Installing a fail-secure lock on an emergency exit.
Poor Maintenance: Rusted panic hardware, broken latches, or doors that don't align properly can all cause a fatal delay.
Incorrect Electronic Lock Installation: Failing to connect a mag-lock to the fire alarm system or not providing a manual override.
These violations are often found in warehouses, small businesses, and older buildings—places where an emergency can quickly become deadly.
Lessons We Can't Afford to Forget
History is filled with tragic events that shaped our modern fire safety codes.
Triangle Shirtwaist Factory Fire (1911): 146 garment workers died, many trapped behind locked doors. This led to major reforms in workplace safety.
The Station Nightclub Fire (2003): 100 people died when a fire engulfed a crowded club. Inward-swinging doors and a panicked rush to a single main exit contributed to the high death toll.
These disasters taught us that panic hardware, outward-swinging doors, and clear, multiple exit routes are not optional—they are essential.
Your Role in Ensuring Safety
Building codes and fire inspectors can only do so much. Safety is a shared responsibility.
For Business Owners and Managers: Your first priority is the safety of your employees and customers. Ensure all exit doors are always clear and functional. Test your panic hardware and electronic locks regularly. Train your staff never to block or lock an exit.
For Employees and Patrons: Be aware of your surroundings. When you enter a building, take a moment to locate the nearest exits. If you see a blocked or chained exit door, report it to management or the local fire department. Your voice could prevent a tragedy.
A compliant door is a promise—a promise that in a moment of crisis, you will have a way out.
The Bottom Line: A Door Must Always Let You Out
From the locked exits at the Hamlet plant to the failing electronic handles on modern cars, the lesson is the same: an exit that doesn't work can kill. Emergency egress is not about checking a box on a compliance form. It is about survival.
Every door in an egress path must be designed, installed, and maintained with one purpose in mind: to open without fail when someone's life depends on it.
