# Crush Prevention Systems: Protecting Your Family
Garage doors are the largest moving objects in most homes, weighing anywhere from 150 to 400 pounds or more. While modern garage doors are designed with safety in mind, understanding and maintaining crush prevention systems is essential for protecting your family from serious injury. This guide explains how these safety features work and what you can do to ensure they're functioning properly.
Every year, thousands of injuries occur due to garage door accidents. Children are particularly vulnerable because they may not understand the dangers or may treat the garage door as a plaything. The good news is that modern safety features, when properly installed and maintained, can prevent the vast majority of these accidents.
Since 1993, federal law has required all garage door openers sold in the United States to include specific safety features. However, many older homes still have outdated systems that lack these protections.
The most common crush prevention feature is the photo-eye sensor system. These sensors are mounted on either side of the garage door opening, about six inches from the ground. They project an invisible infrared beam across the door's path.
How They Work When the beam is broken by a person, pet, or object, the door immediately stops and reverses direction. This prevents the door from closing on anything in its path.
Maintenance Tips - Keep the sensor lenses clean and free of dirt, cobwebs, and debris, Ensure nothing blocks the sensors' line of sight, Check that the sensors are properly aligned (most have indicator lights) - Test the system monthly by placing an object in the door's path
This secondary safety feature uses physical pressure to detect obstructions. When the closing door contacts an object, a sensor in the opener detects the resistance and reverses the door's direction.
How It Works Modern openers are calibrated to reverse when they encounter a specific amount of resistance.typically about 30 pounds of force. This sensitivity can be adjusted but should only be set by a qualified technician.
Testing the Feature Place a roll of paper towels on the floor in the door's path. When you close the door and it contacts the roll, it should reverse immediately. If it doesn't, the force settings need adjustment.
Newer garage door openers include advanced entrapment protection systems that go beyond basic sensors:
Timer-to-Close Features If the photo-eye sensors are obstructed for an extended period, the door will not attempt to close, preventing accidents when something has been left in the door's path.
Battery Backup During power outages, battery backup systems ensure safety features continue to function.
Smart Monitoring Wi-Fi-enabled openers can send alerts to your phone if the door is left open or if sensors detect unusual activity.
Teaching children about garage door safety is crucial:
1. Never Play Under the Door: Explain that the garage door is not a toy and should never be treated as one.
2. Keep Remote Controls Away: Store remotes out of children's reach. Wall buttons should be mounted at least five feet from the floor.
3. Don't Race the Door: Teach children never to run under a closing door.
4. Emergency Release: Show older children how to use the emergency release handle if someone becomes trapped.
5. Finger Safety: Explain the danger of putting fingers between door sections.
Watch for these warning signs:
- Sensor lights aren't lit: This may indicate power issues or misalignment - Door doesn't reverse when tested: The auto-reverse feature isn't working properly - Door reverses for no apparent reason: Sensors may be dirty or misaligned - Unusual noises during operation: May indicate mechanical problems - Door closes too quickly: Spring or cable issues that need immediate attention
If your garage door opener was manufactured before 1993, it likely lacks modern safety features. Upgrading to a new opener with current safety technology is one of the most important investments you can make for your family's safety.
Signs you need an upgrade: - Your opener doesn't have photo-eye sensors, The auto-reverse feature doesn't work reliably, Your opener is more than 20 years old, You want smart home integration and battery backup
We recommend annual professional safety inspections. Our technicians will:
- Test all safety features and make necessary adjustments, Inspect springs, cables, and hardware for wear, Ensure proper door balance, Clean and align sensors, Check opener settings and programming, Provide recommendations for any needed repairs or upgrades
Beyond mechanical safety features, consider these precautions:
Lighting Ensure your garage is well-lit so you can see clearly when the door is operating.
Motion Sensors Consider adding motion-sensor lights that activate when someone enters the garage.
Regular Maintenance Keep all parts properly lubricated and maintained to ensure smooth, predictable operation.
Emergency Procedures Know how to operate the emergency release and ensure all family members know what to do if someone becomes trapped.
