What is Safety Management DX

Safety Management DX refers to initiatives that use digital technologies to transform workplace safety management. Recently, many workplaces such as construction sites and factories face serious issues like labor shortages and an aging workforce, and traditional personnel-reliant safety management has reached its limits. Moreover, work-related accidents such as falls from heights and collisions with heavy machinery remain common, so sites aiming for zero occupational accidents need new countermeasures. Against this backdrop, governments and companies are accelerating efforts to strengthen safety measures through digital transformation (DX). Safety Management DX leverages technologies such as IoT (Internet of Things) and AI (artificial intelligence) to monitor hazards in real time, enabling preventive measures and rapid response in emergencies. Among these, the use of location information for “real-time monitoring” is attracting particular attention.

The Importance of Location Information in Safety Management

Location information is emphasized in safety management because being able to instantly know “who is where” underpins effective safety measures. On large job sites or complex plant facilities, it is not easy to continuously and accurately know the location of every worker. However, with digital technologies, the current positions of employees and vehicles can be tracked in real time and monitored from a single location. By using location information, functions such as monitoring entry into hazardous areas and proximity alerts can be automated, dramatically improving and sophisticating safety checks that previously relied on manual patrols and radio communication. In emergencies, sharing location information allows managers to instantly know “who is exposed to danger and where,” enabling precise rescue or evacuation guidance. In short, real-time utilization of location information is an indispensable element for realizing Safety Management DX.

How Real-Time Monitoring Systems Work

A real-time monitoring system uses IoT devices and sensors to continuously measure and transmit the positions of people and objects on site so that managers can monitor them in real time. Specifically, wearable devices carried by workers (small sensors attached to safety helmets or vests, smartphones, etc.) and transmitters installed on heavy equipment and vehicles continuously send position data to the cloud or an on-site server. For outdoor positioning, satellite positioning systems (GNSS), including GPS, are used to visualize the movements of workers and vehicles on a map across large construction sites and plant premises. GPS errors are on the order of several meters (several ft), but if higher accuracy is required, combining it with high-precision positioning methods such as RTK can achieve centimeter-level accuracy (half-inch accuracy).

In environments where GPS does not reach, such as indoor factory floors or underground, positioning technologies using beacons (Bluetooth, UWB, etc.) or RFID are used. For example, attaching a Bluetooth beacon to a worker’s helmet and using receivers installed in the building to determine position is one method. This enables position tracking for people and objects both indoors and outdoors. Collected location information is displayed in real time on a dashboard on the site supervisor’s PC or the manager’s smartphone. Worker icons move dynamically on the map, and by concurrently displaying hazardous areas and the operating ranges of heavy machinery, the overall safety status of the site can be grasped at a glance.

The system not only displays positions but also includes alert functions for abnormal conditions. When preset conditions are met (for example, “entry into a restricted area,” “approaching a heavy machine,” or “no movement for a certain period”), the system automatically issues alerts or notifies managers. It can also warn the worker’s own device via vibration or an alarm, immediately detecting near-miss incidents and nipping potential accidents in the bud. In this way, a real-time monitoring system is a form of “digital safety supervision” that watches over the site using IoT and location information.

Use Cases of Safety Management Using Location Information

Real-time utilization of location information has created various use cases in workplace safety management. Below are the main examples.

• Preventing contact with heavy machinery: Positioning devices are fitted to both workers and heavy machinery to continuously monitor the distance between them. For example, systems exist that immediately sound an alarm when a worker approaches within a certain distance of operating vehicles such as backhoes or forklifts. This alerts both drivers and pedestrians and prevents contact accidents around machinery. Poor visibility or blind spots often cause near-miss incidents on site, but location-based alerts act as a “third eye” to compensate for these gaps.

• Detection of entry into hazardous areas: Virtual geofences (electronic boundaries) for no-entry or caution areas—such as crane swing ranges, high-altitude work zones, or high-temperature/hazardous areas in chemical plants—are preconfigured on the map. If a worker approaches too close or enters such an area, an alarm sounds and notifications are sent to the individual and managers. This prevents inadvertent entry into hazardous zones and allows the system to act as a watcher without safety personnel constantly standing guard.

• Immediate response to falls and health abnormalities: By linking posture changes detected by a worker’s wearable sensors (falls or drops) or abnormalities in heart rate and body temperature (signs of heatstroke) with location data, rapid emergency response becomes possible. For example, if a worker falls from a height during high-altitude work, an accelerometer detects the fall and simultaneously sends the location information to first responders. This enables nearby colleagues or rescue teams to rush to the scene immediately, preserving the golden time critical for saving lives. Similarly, if a worker shows signs of heatstroke, the management system can detect abnormal values and promptly prompt rest or arrange assistance.

• Safety confirmation and evacuation support during disasters: Location information is also effective during emergencies such as earthquakes or fires. If workers’ ID cards or helmets are fitted with RFID tags or beacons, the system can determine in real time who has successfully evacuated. As workers move toward pre-registered evacuation points, managers can confirm everyone’s positions on the management screen, making it obvious if anyone is left behind. This enables faster and more accurate safety checks than traditional roll calls and allows immediate dispatch of rescue teams if necessary. Conducting such drills regularly also strengthens BCP (business continuity planning).

As described above, real-time location-based monitoring enhances workplace safety in many scenarios. Its major feature is enabling preventive safety management, not just reactive accident handling. Because data can be analyzed to determine “where risks are hidden” or “which tasks produce many near-misses,” it also helps improve future safety plans. The scope of location information use will continue to expand, potentially changing conventional site practices.

Benefits of Implementing Location-Based Monitoring

Implementing a real-time monitoring system brings a wide range of benefits to companies and sites. The main benefits are summarized below.

• Prevention of occupational accidents: By warning of hazardous contacts or intrusions in advance, the system can reduce the rate of accidents caused by human error. A continuous monitoring net covers oversights and careless mistakes, contributing to the prevention of serious accidents. If an abnormality occurs, immediate detection and response can also prevent further damage.

• Efficiency of safety management: Digital monitoring allows a small team to manage safety across large sites. Tasks that previously required safety patrols or manual rounds can be covered 24/7 by the system, reducing the burden on safety personnel and enabling labor savings. Maintaining and improving safety levels despite labor shortages is a significant advantage.

• Increased worker sense of security: Workers also gain reassurance knowing that help will come quickly if a hazard is detected. This can be comforting, especially regarding heatstroke or sudden illness. However, it is important when implementing the system to carefully explain its purpose (ensuring worker safety) and obtain site consensus so as not to create the pressure of “being constantly monitored.” When operated properly, monitoring systems provide both workers and managers with a sense of safety and trust.

• Improved productivity and operational efficiency: Beyond safety, visualizing location information contributes to operational efficiency. Real-time optimization of personnel deployment and immediate location of equipment and materials reduce wasted time and movement. Fewer accidents mean fewer work stoppages, ultimately improving overall project productivity and reducing costs. Because it enables both safety and efficiency, DX-based monitoring systems offer substantial managerial benefits.

Thus, implementing a location-based monitoring system offers the dual benefits of improved safety and operational efficiency. It raises the safety culture on site while supporting a shift to smarter working practices through DX.

Key Points to Succeed with Safety Management DX

To successfully implement location-based Safety Management DX at your sites, several points should be considered. Simply introducing the latest technology aimlessly is not enough; planned adoption tailored to your situation is important.

• Clarify issues and objectives: First, identify “what safety issues you want to solve.” For example, “near-misses between heavy machinery and pedestrians are frequent,” “we want to reduce fall risk during high-altitude work,” or “it takes too long to confirm safety after a disaster.” Clarify these issues and define the objectives for introducing a monitoring system. Clear objectives lead to selecting the appropriate solution.

• Start small and validate: When introducing DX technologies for the first time, it is effective to start with a small-scale deployment rather than replacing everything at once. Pilot the monitoring system in a limited area or with a small team to verify its effectiveness and operational challenges. For example, give wearable devices to several workers for a few weeks, and check alert frequency, data accuracy, and worker reactions. A small start enables quick PDCA cycles at low cost and short duration, reducing failure risk while refining the system to fit the site.

• Gain field staff understanding and provide training: DX tools are effective only when users operate them correctly. Carefully explain the purpose and usage of the monitoring system to workers and supervisors, and provide sufficient training. Share “why we’re introducing it,” “when alarms will sound,” and “how the data will be used” to raise safety awareness and reduce resistance to technology across the site. Actively incorporate feedback from field staff into operational rules and system settings.

• Integrate with existing systems: For effective Safety Management DX, integrate the location-based monitoring system with other in-house systems. For instance, integrating with time-and-attendance or work-reporting systems enables monitoring tied to clock-in/out and automatic logging of incidents. Combining data with security camera footage or environmental sensors creates a more multifaceted safety management platform. Choose systems that are easy to expand and work with your IT department and vendors to customize as needed.

By following these points and promoting Safety Management DX step by step, you can embed technology into the site without undue disruption. Safety is not achieved in a day, but by skillfully leveraging DX, you can steadily approach the ideal of “zero accidents.”

Digitizing the Site with Simple Surveying Using LRTK

As a foundation supporting Safety Management DX, obtaining high-precision location data is indispensable. No matter how advanced the monitoring system, inaccurate location data leads to false alarms or missed detections. One solution that meets this need is simple surveying using LRTK. LRTK is a positioning system that combines an ultra-compact RTK-GNSS receiver attachable to a smartphone or tablet with a dedicated app and cloud service, designed so anyone can easily perform centimeter-class surveying (centimeter-level accuracy (half-inch accuracy)).

Traditionally, centimeter-level surveying required expensive equipment and specialized knowledge. But with LRTK, no complex setup or large-scale equipment is necessary. On site, attach the LRTK device to a smartphone with a single touch and walk around to automatically acquire high-precision position data. The acquired data can be recorded and shared in the cloud, allowing even non-surveying specialists to instantly digitalize site conditions on a map. For example, if you measure benchmark points or boundaries of hazardous areas with LRTK on a construction site, you can reflect accurate information on the monitoring system’s maps. If you visualize routes of underground buried pipes and cables by combining LRTK with AR technology, you can prevent accidental damage during excavation.

In short, simple surveying with LRTK is a new surveying method that “makes RTK-level high accuracy accessible to everyone,” and is a powerful tool for digitizing sites. Because it enables the rapid acquisition of high-precision site data, it can be applied not only to safety management but also to construction planning and quality control. Its usefulness is already being proven on many sites, overturning the conventional idea that surveying is only for specialists. Combined with real-time monitoring systems, LRTK can help build a digital twin of the site and further accelerate Safety Management DX.

Conclusion

Safety Management DX using location information is making real-time workplace monitoring a reality. Sensing and visualizing the movements of people and machines, and having AI and IoT monitor 24/7, is overwhelmingly faster and more accurate than traditional manpower-based approaches. To prevent major accidents and minimize damage in the event of an incident, the use of digital technologies is now indispensable. Companies starting Safety Management DX should take a small first step to introduce technologies suited to their sites and foster a data-driven safety culture.

Fortunately, a variety of easy-to-adopt IoT devices and cloud services are now available, making it feasible for not only large enterprises but also small and medium-sized businesses to try DX-based safety management. Tools like LRTK make previously difficult site digitalization much smoother. By skillfully adopting the latest technologies, realize “DX that protects people” and aim to create workplaces where all workers can work with peace of mind.
