The Importance of Garage Door Safety
Garage doors are powerful mechanical systems. The average residential garage door weighs 150-250 pounds and moves on high-tension springs that store enough energy to cause serious injury. According to the U.S. Consumer Product Safety Commission, garage doors are involved in thousands of injuries and several deaths each year — most of which are preventable.
At Nova Garage Door Repair Solutions, safety is not just a feature — it is our priority. Here is everything you need to know about keeping your family and property safe.
Essential Safety Features Every Garage Door Should Have
Auto-Reverse Mechanism
Required by federal law since 1993, the auto-reverse mechanism forces the door to reverse direction if it contacts an object while closing. Your door should reverse within two seconds of contacting a 1.5-inch-high obstruction placed on the ground. Test this monthly with a 2×4 laid flat in the door path.
Photo-Eye Sensors
Required on all openers manufactured after 1993, photo-eye sensors project an invisible infrared beam across the garage door opening about six inches above the floor. If anything breaks this beam while the door is closing, the door immediately reverses. The sensors have small LED lights — green means properly aligned, red or no light means misaligned or blocked.
Common issues with photo-eye sensors include misalignment from bumps or vibration, dirty lenses from dust and cobwebs, sun interference (direct sunlight hitting a sensor), and wiring damage from rodents or moisture.
Manual Release Cord
The red cord hanging from the opener trolley is your emergency manual release. Pulling it disconnects the door from the opener, allowing you to operate the door by hand during power outages or opener failures. Every family member old enough to operate the door should know where it is and how to use it.
Garage Door Safety for Families with Children
- Mount wall buttons high: The wall-mounted door control should be at least 5 feet above the floor — out of reach of small children.
- Store remotes securely: Do not leave remotes where children can reach them. Garage door remotes are not toys.
- Teach awareness: Make sure children understand that the garage door is heavy and dangerous, and they should never run under a moving door.
- Never let children play near the door: Fingers can be caught between panels as the door opens and closes. Modern doors have pinch-resistant panels, but older doors may not.
Security Considerations
The Garage as an Entry Point
The garage is the most common unauthorized entry point in residential burglaries. A garage door left open — even briefly — is an invitation. Consider these security measures:
- Timer-to-close: Many modern openers can automatically close the door after a set period. If you forget to close it, the opener does it for you.
- Smart monitoring: LiftMaster myQ and similar systems send alerts to your phone when the door opens or closes. You can also close it remotely.
- Lock the interior door: Always keep the door between your garage and house locked, even when the garage door is closed.
- Secure the emergency release: Burglars can use a coat hanger through the top of the door to pull the emergency release cord. A simple zip tie on the release latch prevents this.
Spring Safety
Garage door springs are the most dangerous component of the system. When a spring breaks, it releases its stored energy violently. Never attempt to adjust, remove, or replace springs yourself. Extension springs should always have safety cables running through them — if a spring breaks, the cable prevents it from flying across the garage.
Carbon Monoxide Warning
If you warm up your car in the garage, always open the garage door first — even in winter. Carbon monoxide is odorless and can build up to dangerous levels in minutes, seeping into your home through interior doors and HVAC systems. Install a carbon monoxide detector in your garage and in rooms adjacent to or above the garage.
When to Call a Professional
Do not delay safety-related repairs. If your auto-reverse does not work, sensors are misaligned and you cannot fix them, the door does not stay up on its own, you see broken springs or frayed cables, or the door moves unevenly or makes grinding noises, call Nova Garage Door Repair Solutions at (833) 289-0732 immediately. Safety issues are emergencies — we offer same-day service and free estimates.
