Keeping Our Schools Safe: Weapons Detection Systems

At Poplar Bluff Schools, student and staff safety is our highest priority. We are committed to providing a safe, welcoming, and focused environment where all students can learn and thrive.

As part of our ongoing efforts to enhance school security, we have implemented state-of-the-art OpenGate weapons detection systems at Poplar Bluff High School, Junior High, and Mark Twain Alternative School. These advanced systems add an extra layer of protection, giving peace of mind to families, staff, and students. By taking proactive steps now, we are demonstrating our strong commitment to preventing potential threats before they reach our school doors.

Frequently Asked Questions

Why did Poplar Bluff Schools choose weapons detectors for the Junior High, Senior High, and Mark Twain schools?
Given the increased awareness around school safety nationwide, our district is taking proactive measures to prevent potential threats from entering the educational environment. Weapons detectors serve as a preventive tool, providing an extra layer of security and peace of mind for families, staff, and students. Future expansion across the district is being considered following this pilot rollout.

Why did district leaders choose weapons detectors instead of traditional metal detectors?
After careful review, it was determined that OpenGate is the most effective system for our schools. These advanced detectors use modern sensors and imaging technology to accurately distinguish between weapons and harmless metal objects, significantly reducing false alarms and improving detection accuracy. Additionally, they are portable and can be used at multiple locations and events.

Which schools will have the detectors?
Poplar Bluff High School, Junior High, and Mark Twain Alternative School will have the weapons detection systems in place.

How does the detection system work?
The system consists of two towers that students and visitors walk through upon entry. If the towers turn green, no threat has been detected, and the person passes through without stopping. If a potential threat is identified, the towers display a red light and sound an alert, and the individual will undergo a quick secondary screening.

What happens if the alarm on the system sounds?
Trained staff will guide the individual through a secondary screening process, which may include checking backpacks or using a handheld metal detector.

Who will conduct the screenings?
Screenings will be conducted by Poplar Bluff R-I staff members who have been thoroughly trained on system operations and safety protocols.

Who will be subject to the screening process?
All students and visitors will be screened before entering the building.

Will students with disabilities also be screened?
Yes. All students will be screened unless it is determined that a student poses no threat or cannot participate due to specific disabilities.

How long will it take for all students to enter the school each day?
Entry time will vary by school. We encourage students to arrive on time. Other districts using similar systems have reported that entry times become quicker each day as students and staff become familiar with the process.

Will screenings occur at public events?
Yes. The system will be used at large events on school grounds, such as athletic games, concerts, and plays, as well as additional events off campus like graduation and prom.

Will the detection system pick up knives?
Yes, knives are among the items the system is designed to detect.

Will the system detect vapes?
Yes, it is also capable of detecting vapes and similar devices.

Is the detection system safe for people with implanted or wearable medical devices?
In line with FDA guidance, visitors and staff with implantable or wearable medical devices should consult their device manufacturer or physician regarding exposure.

Will students need to remove items from their backpacks?
Chromebooks, laptops, and large metal notebook spines may activate the system due to their shape and metal density. More detailed guidelines for these and other items will be provided to students and families prior to implementation.

Is the system safe for daily, long-term exposure?
Yes. The system uses extremely low-frequency radio waves (ELF), a non-ionizing technology compliant with the Institute of Electrical & Electronics Engineers (IEEE) 2019 safety guidance for general public exposure.

Does the system use facial recognition?
No. The technology does not use facial recognition. It evaluates objects passing through, not personal identity.

Is there a board policy governing student searches and metal detectors?
Yes. Board of Education policy was revised and adopted in December 2024.  Policy JFG: Searches of Students now covers the use of Weapons/Metal Detectors in our schools.
