Description

Technical Field

[0001] This disclosure generally relates to industrial facility safety, and more specifically, to identifying assembly points and conducting headcounts during hazardous incidents at industrial facilities. Background Technology

[0002] Industrial facilities require continuous monitoring for any potential hazards that could affect the environment, people, and assets to ensure safe operation. Furthermore, facilities must ensure that emergency response plans are implemented in a safe and timely manner during any incident, thereby ensuring no impact on personnel.

[0003] Some types of hazards that may be encountered include gas leaks, where the leaked material may be toxic or flammable, or otherwise pose a serious danger to human health, making immediate evacuation crucial. The leaked material may not be static but may form a continuously spreading, moving gas cloud, which may affect or dynamically change the safest location where people should assemble away from the danger. Therefore, it is essential to dynamically determine the safest assembly point during a hazardous situation and guide people there, as well as to be able to electronically conduct headcounts to confirm that everyone is out of danger.

[0004] Wind direction and speed are other important factors for industrial facilities. In the event of a toxic gas leak or a severe storm, the collection of wind direction and speed measurements by the plant's emergency response team is crucial for initiating industrial evacuation procedures. Based on the wind speed and direction measurements collected on-site, the incident response team can immediately and more definitively determine how to guide evacuees to the safest assembly area within the plant, thereby keeping them away from released toxic gases or avoiding exposure to high wind speeds and ensuring they receive appropriate shelter. Summary of the Invention

[0005] The following is a summary description of various details of this disclosure to provide a basic understanding. This summary is not an exhaustive overview of the disclosure, nor is it intended to identify any key elements of the disclosure or to define its scope. Rather, the main purpose of this summary is to present some of the concepts of the disclosure in a simplified form before the more detailed description that follows.

[0006] According to an embodiment consistent with this disclosure, a facility safety method includes: establishing one or more Smart Assembly Point Systems (SAPS) at different locations relative to the facility; detecting environmental parameters at each SAPS, including wind speed, wind direction, ambient temperature, and the presence of a target gas; determining whether a hazardous situation exists based on the detected parameters; issuing an alarm to personnel regarding the hazardous situation, the alarm including providing the location of the SAPS at the clean air assembly point; and conducting a personnel count at the SAPS at the clean air assembly point.

[0007] In another embodiment, a Smart Assembly Point System (SAPS) includes: an outdoor reinforced structure having: a sensor platform for detecting environmental parameters, including wind speed, wind direction, ambient temperature, and the presence of a target gas; a signal system for sending signals to personnel based on the detected environmental parameters; a power supply for autonomously powering the SAPS; a headcount platform operable to track personnel at the SAPS; and a communication module for wirelessly transmitting the environmental parameters and headcount indication information to a remote server.

[0008] In any emergency evacuation, accurate and rapid headcount methods play a crucial role in the successful implementation of a facility emergency response plan. This is clearly demonstrated by how quickly the facility rescue team can identify the names and locations of victims immediately following an emergency evacuation of the affected plant. This can be achieved by the technology disclosed herein, which allows assembly personnel in the assembly area to access the system's headcount reporting website and report their identification (i.e., name, ID number, organization name). All this data provided by the assembly personnel is immediately reviewed by the plant's Emergency Control Center (ECC) and used to initiate emergency rescue operations for victims and missing persons with minimal input; in contrast, existing manual headcount and rescue methods are inaccurate in many cases.

[0009] Any combination of the various embodiments and implementations disclosed herein can be used in other embodiments consistent with this disclosure. These and other aspects and features will be understood from the following description of certain embodiments given in accordance with this disclosure and the accompanying drawings, as well as the claims.

[0015] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. For consistency, similar elements in the figures may be denoted by similar reference numerals. Furthermore, in the following detailed description of the embodiments of this disclosure, numerous specific details are set forth to provide a more thorough understanding of the claimed subject matter. However, it will be apparent to those skilled in the art that the embodiments disclosed herein can be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description. Moreover, it will be apparent to those skilled in the art that the scale of the elements shown in the drawings may vary without departing from the scope of this disclosure.

[0016] Embodiments consistent with this disclosure generally relate to industrial facility safety, and more specifically, to identifying assembly points and conducting headcounts during hazardous events at industrial facilities.

[0017] Figure 1 This is a schematic diagram of a facility safety management system 100 according to certain embodiments. System 100 can be installed in any industrial facility (e.g., an oil refinery) where hazardous situations may occur and the well-being of personnel must be ensured. Hazardous situations may be attributable, for example, to accidental leaks of toxic and / or flammable gases, and may be exacerbated by weather conditions such as strong winds and / or changes in wind direction. The leak source may originate from the facility itself or from a neighboring facility, but in any case, it must be detected and adequate remedial measures taken to protect people and property.

[0018] System 100 includes one or more Smart Assembly Point Systems (SAPS) 102 distributed throughout the facility. SAPS 102 can be stand-alone outdoor reinforced structures (e.g., stainless steel structures), such as... Figure 1AAs shown in more detail, the SAPS 102 is self-powered via, for example, solar photovoltaic (PV) panels or wind turbines, and provides adequate visibility for factory personnel through illuminated cube markings visible from four sides (e.g., “EMERGENCY ASSEMBLY POINT”), alarms, beacon lights, etc. Furthermore, as detailed below, access points via network connectivity provide access to the factory intranet / internet for facilitating assembly at designated, verifiable locations away from hazards. The structural sides of the SAPS 102 can be, for example, glass or plastic, transparent in the text areas and backlit by a light source controlled by a pair of photosensitive elements. This light source is activated at night, in dense smoke, or other low-visibility conditions, making the text (e.g., “EMERGENCY ASSEMBLY POINT”) clearly visible. Because the connection is wireless and power is generated locally via PV panels and / or wind turbines, no external wiring is required.

[0019] like Figure 1 As shown, SAPS 102 communicates with emergency control center 104 via network 106, which may include the facility's Internet / intranet. Preferably, each SAPS 102 communicates with network 106 wirelessly, as shown by wireless communication channel 108, for example, using cellular or WiFi mode. Emergency control center 104 communicates with network 106 and SAPS 102 via communication channel 110, which may be wired, wireless, or a combination thereof. Similarly, emergency control center 104 may also communicate with the facility's operations control room 112 to integrate the facility's functions and controls, as well as its emergency response and preparedness status.

[0020] Figure 2 To illustrate some details of the SAPS 200, a block diagram is shown. The SAPS 200 can be used with... Figure 1The SAPS 202 is identical to the SAPS 102 in the example. A processor 202 (e.g., a Raspberry Pi computer board that can communicate with an Arduino Mega 2560) is operable to manage some or all of the functions of the SAPS 200 and its components. The processor 202 is coupled to a sensor module 204, which includes a sensor platform 206 operable to receive local environmental parameters, such as wind speed, wind direction, ambient temperature, and the presence of a target gas at the location of the SAPS 200, as well as potentially non-local environmental parameters—such as parameters from other SAPS 200s. Local environmental parameters are collected by appropriate sensors 208, which are operable to determine, for example, wind speed and direction, temperature and humidity, the presence of various target gases (e.g., CO, NH3, and H2S), the lower explosive limit (LEL), and other parameters that may be valuable in determining whether a hazardous situation is forming and requires intervention; such intervention is achieved, for example, by evacuating and / or assembling personnel at a safe location, such as one or more designated SAPS 200s that are determined to be in a suitable condition (i.e., the air is clean and free of leaking gas and the LEL is at a safe level). The collection of parameter information by the sensors 208 can be, for example, continuous, periodic, or event-driven, and different sensors can operate on different schedules.

[0021] SAPS 200 also includes a communication module 210, which includes a wireless transceiver 212 (e.g., an LTE device) for wirelessly coupling SAPS 200 to network 106. Figure 1 This allows environmental parameters and other information to be transmitted to the emergency control center 104 ( Figure 1 This can be achieved using Network Packet Protocol (BTC) and a network switch 214 can be configured for this purpose. In some embodiments, SAPS 200 provides continuous 24 / 7 (all-weather) readings (temperature, hydrogen sulfide (H2S), lower explosive limit (LEL), wind speed and direction) from system rack-mounted sensors 208. All abnormal sensor readings can be logged in the SAPS environmental event logger (not shown) and can be accessed via a system website, such as one hosted by Emergency Control Center 104 or Operations Control Room 112. Any abnormal sensor readings can be logged in the system event logger and are given in conjunction with the following details:

[0022] Date and Time

[0023] • Severity level: Moderate, High, Normal (Low)

[0024] Sensor values

[0025] • Wind speed and direction during periods of high gas emissions or high wind speeds.

[0026] In some embodiments, SAPS sensor readings are continuously collected 24 / 7 by Platform 204 unit (e.g., Raspberry Pi). Abnormal sensor readings are registered on the platform and can be retrieved at any time via the system website for use by facility safety consultants / investigators whenever needed to optimize safety conditions within the industrial facility or identify the root cause of an incident during a crisis investigation. These automatically registered sensor readings include industrial gas (e.g., H2S, LEL, CO, NH3, etc.) sensor readings, temperature sensor readings, and wind speed and direction sensor readings.

[0027] Conversely, clean air conditions at SAPS 200 can be tracked to direct personnel to a safe SAPS location in case of an emergency. This recorded data serves as crucial detail for any plant safety consultant to investigate plant safety and weather-related issues and propose corrective actions. Furthermore, during follow-up reviews, the SAPS environmental event recorder can be used as an official tool to investigate any gas leak safety issues and report them to plant management for prompt decision-making on corrective actions.

[0028] SAPS 200 also includes a personnel tracking module 216, which includes a WiFi access point 218 and a headcount platform 220. In some embodiments, personnel approaching SAPS 200 can be counted for security purposes. For example, when they enter the range of access point 218, they are connected to the factory intranet / internet via access point 218, thereby joining the factory network domain. They can then use, for example, a smartphone or tablet to scan a QR code displayed at SAPS 200 to report their presence at that particular SAPS at that time. The headcount platform 220 is operable to track this information and forward it to the emergency control center 104 via communication module 210. In some embodiments, a headcount database 221 located at SAPS 200 and / or control center 104, or a combination of both, can track counted personnel, and the headcount module 220 or similar module at the data control center can query this database to identify missing persons. Headcount information and environmental parameters for that specific SAPS 200 location, along with those for other SAPS locations, can be displayed in real-time on the system monitoring website for review by personnel and emergency operators. This information can be used to determine, for example, which personnel have assembled at which SAPS 200 location to take appropriate safety measures. In some embodiments, additional safety measures may include sending alerts to personnel-carried factory radio terminals or via email to personnel's smartphones or tablets, informing them of hazardous conditions (e.g., changes in wind speed / direction, presence of hazardous gases), evacuation instructions to be followed, such as evacuation routes to clean air SAPS locations. In some embodiments, alerts / emails may be automatically sent whenever high wind speeds and gas levels (e.g., H2S and LEL) exceeding their normal levels and reaching moderate or high levels (or vice versa). Alert messages may be sent whenever the system determines that wind speed, temperature, and gas leak levels change from normal to moderate, or from moderate to high (or vice versa). Alert messages may include the latest readings from system sensors, such as wind speed, wind direction, ambient temperature, H2S gas levels, and LEL gas levels.

[0029] As described above, SAPS 200 is equipped with a signaling system 222, which includes various beacons and signaling devices to improve visibility and enhance its function as an assembly point in emergencies (this can be determined by the emergency control center 104 based on environmental parameters transmitted by SAPS 200), and in some embodiments, in conjunction with environmental parameters transmitted by other SAPS devices within the facility. Signaling devices may include flashing lights of different colors, sirens and horns, pre-recorded announcements, etc., and are preferably sufficiently loud and / or visible both day and night, even during severe weather and other catastrophic events (e.g., fires, explosions, sandstorms, power outages, etc.). In some embodiments, triggering one or more of these signals can be performed locally, i.e., triggered by SAPS 200 itself without a command from the emergency control center 104. Triggering may be based on the detection of a target leak of gas of a threshold amount, LEL, changes in wind speed or direction (increase or decrease), etc., and in some cases determined by the processor 202; and / or automatically triggered by the emergency control center 104 and / or triggered by a human operator there.

[0030] The SAPS 200 and its components are powered by a power source 224, which may include one or more autonomous green energy sources 226, such as photovoltaic (PV) panels, wind turbines, etc., and batteries (not shown) for storing the electrical energy. In this way, the SAPS 200 can be self-contained and does not require power cable connections, but can be installed anywhere within the facility where power can be generated (i.e., a sunny location suitable for PV battery operation, etc.). This operating method makes the SAPS particularly suitable for installation in new areas without wired power and data connections, and at temporary facilities known to be high-risk, such as oil drilling and well workover operations, pipeline construction, or maintenance.

[0031] Alternatively, one or more SAPS 200 units may be vehicle-mounted and draw power from the vehicle's battery. These mobile SAPS units offer the flexibility for rapid and / or temporary installation and operation and can be deployed in factory operations or industrial security patrol vehicles. This is considered extremely useful in situations where an existing designated collection area becomes hazardous and unsuitable due to, for example, excessively high levels of H2S and LEL emissions, guiding personnel to an unplanned safe location.

[0032] In some embodiments, an arrangement of SAPS 200 can be deployed to enable better location tracking of hazardous situations, particularly in large industrial cities with multiple factory facilities that could become sources of gas leaks. (Refer to...) Figure 3Such an arrangement may include: a first perimeter group of SAPS 1-4 installed at the plant boundary fence (“Boundary A”); and a second interior group of SAPS 5-8 installed inside the plant (“Boundary B”). All SAPS 200 in both groups are prepared to detect and report any anomalies in H2S and LEL emissions and to continuously report to the operators at Emergency Control Center 104. The primary purpose of providing two groups of SAPS is to determine the flow direction of H2S and LEL gases to determine whether they are being released from inside the plant or leaking from an adjacent (nearby) plant (not shown). Figure 3 The system comprises eight distributed SAPS 200 units. Plant operators can access the website of each SAPS unit individually and browse the active gas emission monitoring records for the selected SAPS area. They can retrieve all necessary details, such as gas type, detection date and time, percentage of detected gas, wind direction, and wind speed. If H2S or LEL gas is detected first or only (one of both) by any SAPS unit at boundary B, it means the gas release originated inside the plant; if it is detected first or only (one of both) from boundary A, the gas leak originated outside the plant. Furthermore, based on the wind direction and speed at the time of the gas leak, the leak direction can be accurately determined, and areas affected by the released H2S or LEL gas can be identified.

[0033] In view of the above structural and functional characteristics, combined with Figure 4 This will help you better understand the example method. Although, for the sake of simplicity, Figure 4 The example methods are shown and described as being executed sequentially, but it should be understood and recognized that this example is not limited to the order shown, as in other examples, some actions may occur in a different order, multiple times, and / or in parallel compared to those shown and described herein. Furthermore, implementing these methods does not necessarily require performing all the described actions; instead, some actions omitted in the specification may also be performed.

Therefore, Figure 4 For examples, please refer to Figures 1 to 3Example. In step 402, one or more Smart Assembly Point Systems (SAPS) 200 are established at the facility. In step 404, environmental parameters such as wind speed, wind direction, ambient temperature, and the presence of the target gas are detected at each SAPS. In step 406, it is determined whether a hazardous situation exists. In step 408, if a hazardous situation exists, an alarm is issued to personnel. The alarm may include indication of the location of the SAPS at the clean air assembly point so that personnel can safely assemble there. In step 410, a personnel count is conducted at the clean air assembly point SAPS and / or other SAPS.
