What is Worker Down Detection?
A safe workplace requires a clear plan for responding to accidents or injuries. That's where worker down detection comes in. It alerts EHS teams immediately when an accident occurs so they can provide assistance as quickly as possible.
This system uses AI and sensors to detect when a worker has fallen and cannot get up. Once activated, it will alert a designated individual or team for prompt assistance.
With advanced AI systems, companies can now implement man-down detection through existing CCTV networks.

How Worker Down Detection Works
Traditionally, worker down detection is possible through a system that uses radio frequency (RF) to send and receive signals.
The device worn by the worker emits a signal that is picked up by the receiver. If the signal is interrupted for more than a few seconds, the receiver will sound an alarm to trigger a response.
The Two Types of RF-Based Systems
There are two main types of RF-based worker down detection systems: passive and active.
- Passive Systems - These systems rely on reflection to detect the signal from the tag. They function well in indoor environments without obstacles between the tag and the receiver.
- Active Systems - Active systems use power-amplified tags that emit their own signals. This allows them to work effectively even in outdoor settings or large facilities where obstacles may disrupt passive systems.
The Odd One Out - Infrared (IR) Technology
Infrared (IR) technology can also be used for worker down detection, but it has some limitations. For example, IR signals can be disrupted by sun glare or reflective surfaces.
Additionally, IR systems require line-of-sight between the tag and receiver, which can make them difficult to use in some industrial applications.
AI Solutions for Reliable Worker Down Detection
Traditional methods, such as wearing worker down devices, are prone to errors. Device failures can jeopardize safety, particularly in high-risk environments. This is why many companies are now adopting AI to improve fall detection.
AI safety systems can be connected to existing CCTV networks. They use advanced technologies such as computer vision and video content analysis to detect worker movement in real time.
Real-Time Safety Monitoring and Emergency Alerts
In case a worker stops moving for a certain period of time, the AI immediately detects it and acts on a preconfigured set of actions.
It can alert the organization’s EHS team or notify a designated employee who is in close proximity.
With no additional devices required, AI-driven worker-down detections are more reliable and can play an integral role in ensuring employee safety, especially in hazardous environments.
4 Key Benefits of Worker Down Detection
Worker down detection significantly reduces response time when an accident occurs. In some cases, every second counts, and by sending out immediate alerts, worker down detection could eventually save lives.
These devices offer many advantages over traditional employee safety monitoring methods, such as manual head counts, which are time-consuming and prone to error.
They are also more effective than personal duress alarms, which depend on user activation. They also surpass isolation monitors, which only provide protection when worn.
Here are a few reasons why worker down detection with AI is so beneficial in promoting a proactive safety culture.
- Automated Monitoring
Worker down detection monitoring is active all the time and does not require any action from the user to send alerts or activate it.
This means that workers can focus on their tasks without having to worry about activating a device or to bother with safety devices getting in their way.
Additionally, integrating PPE monitoring with worker down detection enhances safety by ensuring compliance with safety gear requirements.
- Increased Accuracy
Unlike manual head counts or personal duress alarms, worker down detection with AI cameras provides continuous monitoring of employees' whereabouts.
This eliminates potential errors that could occur if someone was accidentally counted twice or if someone forgot to activate their personal alarm.
- Instant Notifications
Most worker-down detection systems have a paging feature that will notify supervisors or other designated personnel when an alarm is activated. This allows for a quick response in case of an emergency.
Additionally, systems with PPE detection provide alerts about whether safety equipment is worn, which is essential for emergency response planning.
- Versatility
Worker-down detection systems can be used in various lone worker apps and sites. It offers valuable worker safety monitoring solutions for improving lone worker safety in diverse environments, including construction sites, manufacturing plants, warehouses, and office buildings.
