Safety products: SafeGuard Sentinel Safety Software
Monitoring system: ACM Facility Safety’s SafeGuard Sentinel measures and monitors plant conditions, detects safety-related issues, alerts operators, and suggests contingency plans.
Utility safety: ACM Facility Safety releases SafeGuard Sentinel safety monitoring software to continuously measure, monitor and alert operations and management to process safety risks. The software also delivers contingency plans that can be executed immediately to address issues and reduce risk. By presenting real-time risk information and expert knowledge to make effective operational decisions, SafeGuard Sentinel helps prevent safety incidents, environmental infractions and downtime.
SafeGuard Sentinel enables plants to reduce risk and identify critical safeguards during operation, and it provides information on which to base strategic decisions, including monitoring of safety performance indicators up to a Board of Directors level.
SafeGuard Sentinel runs on a Windows-based server in a plant network, and can be accessed by any device capable of running a browser, including DCS workstations, operator terminals, tablets and smartphones.
The SafeGuard Sentinel server connects through OPC and ODBC, allowing it to gather information from a variety of systems including DCSes, PLCs and PACs from all major control system suppliers. Other sources of data typically include safety systems, historians, SCADA systems, maintenance systems, operator logbooks and workflow tracking systems.
Depending on the network setup, SafeGuard Sentinel can be hosted in the plant DMZ, which allows access at a business level. SafeGuard Sentinel only needs one-way communication from the various systems to gather data, thus preserving plant security.
SafeGuard Sentinel integrates data from these various systems to create an all-inclusive database of information including Hazard and Operability (HAZOP) Studies and Layer of Protection Analysis (LOPA). SafeGuard Sentinel uses this information to provide situational analysis and contingency plans for process safety situations.
In real-time, SafeGuard Sentinel monitors plant conditions, detects unsafe conditions, and alerts operators. SafeGuard Sentinel also captures risk events and operator actions for immediate visualization and future analysis.
By comparing the real-time measured risk level with the designed level of risk, SafeGuard Sentinel provides quantitative, leading metrics showing changes in risk over time. Management can use SafeGuard Sentinel to see how process risk is changing, and can benchmark safety performance across process units or entire plants. Drawing upon information from sources such as maintenance and training records, SafeGuard Sentinel reveals risks that would normally be undetected.
SafeGuard Sentinel provides “Bowtie Displays” which convert pages of HAZOP data into a single, powerful, and easy to understand graphical visualization. This helps operators understand the full scope of each potential risk, and see the impact of each safeguard. All risks and mitigations are shown on bowtie visualizations which include:
• Hazardous events
• Root causes
• Preventative safeguards
• Mitigative safeguards
• Contingencies for safeguard failure
