In a K12 school emergency, school safety notifications must reach every person on campus.
According to a recent RAND roundtable, a variety of safety incidents are impacting schools every day. In these time-sensitive situations, students and staff who are deaf or hard of hearing or those who are in loud, busy areas, may miss auditory notifications.
As districts enhance school safety with investments in technology, visual notifications, such as strobes, have emerged as an essential part of a comprehensive school safety plan. When strategically placed throughout a school campus, strobes provide critical alerts that aren’t blocked by typical school noise levels to notify everyone.
Limitations of traditional digital signage and intercom systems
While many districts use traditional notification methods, such as intercom announcements or digital signage, to communicate emergencies, these channels have limitations in coverage and accessibility.
Intercom systems can fail to reach individuals in loud environments such as gymnasiums, cafeterias or music rooms. Similarly, digital messages are typically displayed only in classrooms or on select screens, leaving hallways, restrooms and common areas excluded from urgent notifications.
To close these gaps, school safety teams must turn to more visible, universally accessible solutions.
Applying fire safety lessons to K12 schools
The fire safety community has long recognized the value of visual notifications in alerting people of an emergency. Fire alarms in buildings and classrooms, for example, often incorporate a bright white light that flashes to alert people of a fire.
In an emergency, that visual notification helps make sure everyone is notified and is able to evacuate quickly and safely. Schools can apply this same principle to broader emergency alert notifications and protocols, ensuring everyone receives the alert, regardless of location or ability.
Strobes deliver fast, reliable campus-wide alerts
Whether students, faculty or staff are walking through a noisy hallway or are in a bathroom in a remote area of the campus, flashing strobes make sure no one misses a critical emergency alert. In a crisis, confusion costs time and time saves lives, making strobes essential for campus-wide notification.
Key reasons strobes should be part of every school’s comprehensive safety planning include:
- Campus-wide awareness is immediate: Strobes notify everyone of an emergency instantly, helping to provide campus-wide safety coverage. According to an analysis of more than 265,000 school safety incidents in the 2024-2025 school year, nearly 60% of incidents occurred outside the classroom. Auditory announcements can be drowned out by noise. Radios require the right channel. Texts can be delayed. Strobes reach everyone, fast.
- Color-coded illumination reduces confusion: Strobes can illuminate in different colors, depending on the type of emergency. For example, green could indicate evacuation, orange to shelter in place and red for a lockdown. This gives staff and students instant visual cues on how to react, activating rapid response and helping to guide behavior in real-time.
- Strobes remain operational in a power outage or extreme weather: Accounting for power outages and extreme weather is a vital part of school safety planning. In emergencies where power is lost, wireless, battery-powered strobes will continue to function, ensuring uninterrupted alerts during extreme weather or infrastructure failure, delivering uninterrupted alerts.
- Visual notifications support accessibility: Considering all students, faculty and staff is essential to ensuring emergency notifications reach everyone. In the U.S., there are more than 300,000 children between the ages of five and 17 who are deaf or hard of hearing, and 13% of adults have some difficulty hearing even when using a hearing aid. Visual notifications ensure that everyone is alerted and can act quickly in an emergency.
Visual notifications are essential to comprehensive protection
Strobes are no longer optional; they are a foundational element of any effective and inclusive emergency alert system. Visual notifications communicate both the urgency of the situation and the appropriate action to take, maximizing safety for everyone on campus.
Strobes make emergency alerts universal—and clearly seen, not just heard—throughout school buildings. When paired with protocols and regular training, visual notifications can save lives.
