It is well known that transporting certain dry dusty materials can create explosive atmospheres. Five conditions, known as the “Dust Explosion Pentagon”, have to exist in order for the explosive state to occur. First, there needs to be a high concentration of dust (fuel), followed by an ignition source (heat) and oxygen (oxidizer). If all of these appear in a confined space with dispersion, an explosion can occur. The most common ignition sources have long been identified as over-heated bearings, misaligned belts, and belts that are slipping. The industry is saturated with various sensors and controllers that monitor these conditions to prevent explosions. Regardless how well these systems work there is one problem with all of them: human error. With the ever-growing demands on site performance and efficiency at terminals and processing facilities, decisions to bypass safety equipment has become an ever increasing issue. With mounting pressures, site personnel may risk keeping a machine in operation even after an alarm has been detected, putting the plant and all personnel at risk. Without backend reporting systems and data logging, this dangerous practice can go on undetected by upper management.
In order to combat this issue, 4B Components has developed a solution that introduces a greater level of transparency and record keeping. HazardMon.com is a secure cloud-based industrial monitoring solution that allows any registered user to login and see all their facilities in real-time from anywhere in the world. This product offers seamless integration with 4B’s T500 Elite Hotbus hazard monitoring system.
Features of the HazardMon.com include the following:
• Secure login and data transfer with standard 256-bit (SSL) encryption, or an optional virtual private network (VPN) connection can also be created
• No server or PLC is required, so there is no additional hardware to replace or backup, which also eliminates upkeep and upgrade costs.
• Data is sent directly to 4B’s cloud server, and automatically backed up in multiple off-site locations making the data extremely safe and secure. This allows data to be easily recovered and analyzed in the case of an on-site event, such as an explosion.
• Live system dashboard, historical data, and customizable graphs can be viewed on any Web-enabled device (smartphone, tablet PC, desktop or laptop computer).
• Email alert notifications can be sent to notify specific users whenever a change in the system’s health is detected.
• New features are constantly being developed to improve the end user experience, and with HazardMon.com’s cloud-based technology, your facility will always be at the leading edge of technology.
Live System Dashboard
With HazardMon.com it is possible to view multiple sites from one system dashboard page (figure 3). This unique feature varies from other systems where you have to login to each site individually and view them one by one. HazardMon.com also indicates all active alarms from all facilities in one place as soon as you log in, allowing managers to see any problems in a matter of seconds.
All sensor data can be viewed in real-time using any standard Web browser such as Mozilla Firefox, Google Chrome, or Internet Explorer (figure 4). The Web site is completely dynamic and the sensor status and value are updated automatically without the need to refresh the webpage. The Web site was designed to dynamically resize as the screen resolution changes and it is optimized for tablet and mobile phone platforms.
Historical Data Analysis
All data can be viewed as graphs. A unique drag-and-drop feature allows you to pick specific sensors of interest and compare them side-by-side in one graphical view (figure 5). Time windows can be selected, ranging from 1 hour to 30 days. The graphs are interactive, allowing you to use your cursor to mouse over any event to show specific values and sensor statuses.
All alarms are stored in a separate alarm log (figures 6 and 7). Using the Web site filtering options, it is easy to generate a report and download it into a standard spreadsheet program. All the alarms are grouped into different alarm types, like “Alarm Detected”, “Alarm Cleared”, “Device Power Up”, etc. This allows information to be extracted in a few clicks and create a report in seconds.
Email and Text (SMS) Notifications Engine
A flexible notification system allows any user to receive email or text message notifications. Notification can be sent when sensors go in and out of alarm; when the Internet connection between the T500 Hotbus system and the server is lost or when an alarm has not been cleared for a number of minutes. It is also possible to receive notifications only when an alarm has not been cleared for a specified number of minutes.
Report Generation Tool
An advanced analytics tool allows reports to be generated that summarize the safety and efficiency of the factory. Currently it is possible to see which sensors caused the majority of alarms, which hours of the day had most alarms, and the types of alarms. The start and end dates of reports can easily be altered and the report re-generated. Reports can be saved to the user’s PC in a single click.
Automated Maintenance and Testing Functionality
It is important to periodically check that your monitoring system will detect an alarm when a dangerous condition occurs. The current standard in the industry is for technicians to walk around the site and manually test each sensor. A paper report is then generated and in some cases, converted into a digital format (Microsoft Excel for example). There is still absolutely no guarantee that the technician actually performed any of the testing. HazardMon’s sensor testing function ensures that test procedures are carried out, logged, and reported within the system. This feature provides managers documented evidence that each sensor has been tested to ensure it is working correctly.
To initiate a system test, a user would go to the “Maintenance” tab within HazardMon.com and choose a sensor to test. During testing, HazardMon temporarily stops alarm notifications for this sensor, so that no nuisance alarm notifications are sent out. The user has five minutes to trigger an alarm and confirm the sensor is in proper working condition or needs to be replaced. The whole process is logged automatically, and a maintenance report can be generated after testing has been completed.
As more facilities install monitoring systems to ensure the site’s safety, the main safety concerns, human error, and the lack of transparency still exist. HazardMon.com combined with 4B’s hazard monitoring systems gives management real-time access to all critical monitoring data. This increases transparency, cuts down on human error, and helps to verify that company safety policies are being adhered to.
