Description

  The present invention relates to a work determination program, a work determination method, and a work determination apparatus.

  At the site of work at height, the worker wears safety equipment and performs work so that the fall and fall of the worker can be avoided as much as possible. In the past, the use of safety belts was entrusted to workers, but in recent years there is known a technology for collecting and managing the use conditions of the safety belts of each worker by a sensored safety belt having a communication function . For example, the safety band with sensor determines whether the hook is in use or not and transmits it to the management server. The management server specifies an operator whose hook is disengaged according to the information received from each worker's safety band with a sensor, and outputs an alarm or the like.

  However, with the above-mentioned technology, it is difficult to detect a worker with a high work risk. For example, by using a safety band with a sensor, it is possible to collect on / off information indicating whether or not the safety band is used, but it is not possible to collect the occurrence of an accident or an attempted accident such as a so-called near miss. For this reason, it is not possible to identify the situation in which an accident actually occurred, etc., and it is not possible to predict the degree of risk of the worker during work.

  In one aspect, it is an object of the present invention to provide a task determination program, a task determination method, and a task determination apparatus capable of detecting a worker having a high task risk.

  In the first proposal, the work determination program installs the safety belt having a transmission function for transmitting attachment information indicating whether or not it is attached to the work site to the computer, and sets the accident occurrence status of the worker who performs the work A process of referring to the storage unit to be stored is executed. The work determination program causes the computer to execute the process of acquiring the attachment information from the safety band of the worker, and acquiring environment information on the work environment of the worker from a sensor worn by the worker. The work determination program causes the computer to execute processing for outputting a warning when the work state specified by the acquired attachment information and the environment information is similar to the accident occurrence state.

  In one aspect, it is possible to detect workers with high work risk.

  Hereinafter, embodiments of a work determination program, a work determination method, and a work determination apparatus disclosed in the present application will be described in detail based on the drawings. The present invention is not limited by this embodiment. Moreover, each Example can be combined suitably within the range without contradiction.

[overall structure]
FIG. 1 is a diagram illustrating an example of an entire configuration of a system according to a first embodiment. As shown in FIG. 1, this system includes a safety belt 1 worn by a worker working at a high place, a sensor 5 worn by the worker on a part of the body, and a management terminal 7 owned by a field supervisor. And the work determination apparatus 10 providing the cloud service are connected in a wirelessly communicable manner. Here, the worker wears one or more safety bands 1 and works at a high place, and the on-site supervisor manages the work content and progress of the worker. Although an example in which the safety band 1 and the sensor 5 are separate housings will be described, the present invention is not limited to this. The safety band 1 may have the sensor 5.

  The safety belt 1 has a judgment function such as a sensor that judges whether or not it is safely attached to a support or fixed object such as a scaffold or a column fixed to the work site, and the mounting information that is the judgment result This is an example of a safety hook or the like having a transmission function to transmit to the device 10. Furthermore, the safety band 1 has a tension sensor, and detects a physical load that rapidly deteriorates when dropped. The tension sensor is turned on when the weight of the worker is suddenly applied.

  For example, the safety band 1 suppresses the determination function, the tension sensor, and the transmission function when stored in the storage unit held by the worker. In addition, the safety band 1 transmits an on signal to the work determination apparatus 10 when the hook part is attached to the work site, and sends an off signal to the work determination apparatus 10 when the hook part is not attached to the work site. Send.

  Further, the safety belt 1 transmits an ON signal to the work determination device 10 when the tension sensor detects tension (body load) equal to or greater than a predetermined value in a state where the hook is normally attached. In addition, when the hook is not properly attached, the safety belt 1 does not operate the tension sensor even if tension (body load) smaller than a predetermined value is generated, and transmits an off signal to the operation determination apparatus 10. Although the transmission interval can be set arbitrarily, for example, transmission is performed every one second.

  The sensor 5 is an example of a measuring device that senses environmental information related to the work environment in which the worker is working and transmits the sensed information to the work determination apparatus 10. For example, the sensor 5 measures the position information (coordinates) of the worker, the height at which the worker is located, the heart rate of the worker, acceleration data of the worker, and the like, and transmits the data to the work determination device 10. Note that various types of sensing and the like can adopt a known method such as GPS (Global Positioning System), and the transmission interval can be arbitrarily set, but for example, transmission is performed every one second.

  The management terminal 7 is an example of a computer device used to manage a work plan of a work site, information on workers, work time, progress, etc., and is, for example, a tablet terminal or a smartphone. When the management terminal 7 receives a warning or the like from the work determination apparatus 10, the management terminal 7 displays a warning on the display to notify the on-site supervisor.

  The work determination apparatus 10 is an example of a computer apparatus that transmits / receives various information by wireless communication of another apparatus, integrally manages installation information and environment information of each worker, and manages past work history and the like.

  In such a system, the work determination apparatus 10 stores the accident occurrence situation of the worker who wears the safety band 1 having a transmission function for transmitting attachment information indicating whether or not the work site is attached, and performs the work. Do. Then, the work determination apparatus 10 acquires attachment information from the worker's safety belt 1 and acquires environment information on the work environment of the worker from the sensor 5 worn by the worker. After that, the work determination apparatus 10 outputs a warning when the work state specified by the acquired attachment information and environment information is similar to the accident occurrence state.

  That is, the work determination apparatus 10 receives the work information of the worker in real time, and detects the work similar to the past accident occurrence situation. Then, the work determination apparatus 10 transmits a warning to the management terminal 7 or the sensor 5 of the corresponding worker when detecting the worker who is performing the work similar to the accident occurrence situation. By doing this, the work determination apparatus 10 can detect a worker who has a high work risk and is in a situation where the possibility of an accident is relatively high.

[Function configuration]
Subsequently, the functional configuration of each device shown in FIG. 1 will be described. The safety band 1 has the same function as the known safety band 1 having a communication function, the sensor 5 has the same function as a general sensor, and the management terminal 7 is a general computer device. And the detailed description is omitted. Here, the work determination apparatus 10 having a function different from the general function will be described.

  FIG. 2 is a functional block diagram showing the functional configuration of the work determination apparatus 10 according to the first embodiment. As shown in FIG. 2, the work determination apparatus 10 includes a communication unit 11, a storage unit 12, and a control unit 20.

  The communication unit 11 is a processing unit that controls communication between other devices, and is, for example, a communication interface or a wireless interface. For example, the communication unit 11 receives the attachment information from the safety band 1, receives the environment information from the sensor 5, and transmits a warning to the sensor 5 or the management terminal 7.

  The storage unit 12 is an example of a storage device that stores programs and data, and is, for example, a memory or a hard disk. The storage unit 12 includes a past history DB 13, an accident situation DB 14, a worker DB 15, a status DB 16, and a sensor value DB 17.

  The past history DB 13 is a database that stores past information acquired from a worker. FIG. 3 is a diagram showing an example of information stored in the past history DB 13. As shown in FIG. 3, the past history DB 13 stores “altitude, safety status ID, tension sensor, physical load, start date, start time, end date, end time, accident flag” in association with one another. .

  The "altitude" stored here is information indicating the altitude of the place where the worker is working. The “safety state ID” is attachment information indicating whether or not the safety band 1 is safely attached. The "body load" is information indicating the detection result by the tension sensor. "Start date" is the date when the work was performed. The "start time" is the time when the work was started. "End date" is the date when the work is completed. The "end time" is the time when the work is completed. The “accident flag” is information indicating the occurrence of an accident, and, for example, the time when the tension sensor is ON or the time when the physical load rises by a threshold (for example, 100) or more is specified as the accident.

  For example, the first line in FIG. 3 is the work history of 13:34:19 on Jan. 3, 2017 to 13:35:02 on Jan. 3, 2017, and safety band 1 was used normally. In the state, the history of working at an altitude of 40 m is shown, the physical load is 8.4%, the tension sensor is off, and no accident has occurred. The accident flag includes not only the occurrence of an accident but also the occurrence of a so-called near-miss that has been prevented in advance.

  For example, in the fifth line of Fig. 3, the physical load suddenly rose due to a drop, etc., but the safety sensor 1 was normally attached, so that the tension sensor for the safety belt 1 was activated and the fall could be prevented beforehand. Indicates In this case, although it can be prevented in advance, since the physical load is equal to or higher than a threshold (for example, 40% or the like), it is determined that a near miss has occurred, and the accident flag is turned on. On the other hand, line 11 in FIG. 3 indicates that the load on the safety belt 1 did not start and the drop occurred because the safety belt 1 was not attached normally because the physical load rapidly increased due to the fall etc. . In this case, it is determined that an accident has occurred, and the accident flag is turned on.

  In addition, although the example which hold | maintains the information containing an altitude and a body load as a past history as an example was demonstrated here, it is not limited to this, holding the other sensor value which can be acquired by sensor 5 You can also. For example, an acceleration value, a heart rate, a position, etc. can also be matched. Also, the information held here can be created from information that can be acquired from the safety band 1 or the sensor 5. Moreover, each information which can be acquired from the safety band 1 or the sensor 5 can also be managed separately.

  The accident situation DB 14 is a database storing characteristics of an accident situation in which an accident or a near incident has occurred. In addition, for the sake of explanation, an accident or a near incident is collectively described as an accident. FIG. 4 is a diagram showing an example of information stored in the accident situation DB 14. As shown in FIG. 4, the accident situation DB 14 stores “height change, change in physical load, job title” in association with one another. The "altitude change" is information on the altitude that has changed from before the accident to the time of the accident, and the "change in body load" is a change in the body load before and after the accident. "Position" indicates the position of the worker.

  In the example of FIG. 4, it is shown that work with a change in altitude of -20 m or more and a change in physical load of -13% or more is similar to an accident occurrence. Similarly, a worker who is a field supervisor and shows an operation with a height change of 0 m to +20 m or more and a change in physical load of + 13% or more is similar to the occurrence of an accident. More specifically, if the physical load drops sharply after working at a height of +20 m or more before the current work, it is determined that the possibility of an accident is high. Similarly, a field supervisor who usually does not work at heights determines that the possibility of an accident is high if the physical load rises sharply when working at heights of 20 m or more after working on the ground.

  In other words, after working for a long time in a high place, it is dangerous to work in a suddenly low place, and similarly, it is judged that it is dangerous for a person who is only working on the ground to work in a high place. Be done. In addition, accident situation is not limited to what is specified by the above-mentioned item, for example, rising value of heart rate, change of acceleration value, working years (years of experience), age, total working time of the day, safety off It can also be identified by the time, type of work, etc.

  Worker DB15 is a database which memorizes information about a worker. FIG. 5 is a diagram showing an example of information stored in the worker DB 15. As shown in FIG. As illustrated in FIG. 5, the worker DB 15 stores “sensor ID, device ID, worker name, job title, contact address” in association with one another. “Sensor ID” is an identifier that identifies the sensor 5 attached to the worker. “Device ID” is an identifier that identifies a safety band used by a worker. The “worker name” is the name of the worker, and the “job title” is the job title of the worker. The “contact information” is a contact information of the worker, and is, for example, an email address, a telephone number, an SNS (Social Networking Service) ID, a Bluetooth (registered trademark) ID, or the like.

  In the example of FIG. 5, the on-site supervisor Patent Taro uses the safety band 1 of “742 b 62 cdc 3” and the sensor 5 of “SS 1”, and shows that the contact point is “XXX”. Patent Hanako uses the safety band 1 of “742 b 62 cdc 5” and the sensor 5 of “SD 1”, and indicates that the contact is “YYY”.

  The status DB 16 is a database that stores mounting information acquired from the safety band 1. FIG. 6 is a diagram showing an example of information stored in the status DB 16. As shown in FIG. 6, the status DB 16 stores “safety state ID, start date, start time, end date, end time, device ID” in association with one another.

  The “safety state ID” stored here is attachment information indicating whether or not the safety band 1 is safely attached. "Start date" is the date when the work was started, and "start time" is the time when the work was started. The “end date” is the date when the work is finished, and the “end time” is the time when the work is finished. The “device ID” is information for identifying the safety band that has transmitted the attachment information.

  The work log in the first line of FIG. 6 is executed from 13:34:19 on July 3, 2017 to 13:35:02 on July 3, 2017, and the mounting information for the device ID “742b62cdc3” is displayed. Indicate that safety band 1 is properly attached in this work. Note that the information stored here can store the received information in time series, or can be stored separately for each device ID.

  The sensor value DB 17 is a database that stores environmental information acquired from the sensor 5. FIG. 7 is a diagram showing an example of information stored in the sensor value DB 17. As shown in FIG. 7, the sensor value DB 17 stores “sensor ID, position information, altitude, physical load, start date, start time, end date, end time” in association with each other.

  The “sensor ID” stored here is an identifier for identifying the sensor 5. The “position information” is information indicating the position of the worker, and is, for example, measurement of coordinates or GPS. "Altitude" indicates the altitude at which the worker is working. “Physical load” is information acquired by the tension sensor of the safety band 1, and is stored in association with time of the information acquired from the safety band 1. As for the physical load [%], for example, when the information that can be measured from the tension sensor is Newton [N], the ratio to the maximum tension [N] that can be secured by the safety belt 1 can be shown in%. Specifically, it can be calculated by “body load [%] = value of tension sensor [%] / strength (maximum tension) at which safety band can ensure safety (%) × 100”. As another example, it can also be calculated by “body load [%] = current value applied to tension sensor [kgf] / maximum weight at which safety band can secure safety [kgf] × 100”. In addition, "body load" can also be managed by status DB16. Note that “start date” and the like are the same as the information described above, and thus detailed description will be omitted.

  The log in the first line of FIG. 7 corresponds to the sensor 5 of the sensor ID “SS1” at the time of work performed from 13:34:19 on July 3, 2017 to 13:35:02 on July 3, 2017. Is the acquired sensor value, and indicates that the position information is “AA” and the altitude is “40 m”. Also, it indicates that the physical load at this time was "8.4%".

  The control unit 20 is a processing unit that controls the entire work determination apparatus 10, and is, for example, a processor. The control unit 20 includes an accident determination unit 21, a collection unit 22, a determination unit 23, and a warning unit 24. The accident determination unit 21, the collection unit 22, the determination unit 23, and the warning unit 24 are an example of an electronic circuit such as a processor or an example of a process executed by the processor. The accident determination unit 21 is an example of a determination unit, the collection unit 22 is an example of an acquisition unit, and the determination unit 23 and the warning unit 24 are examples of a warning output unit.

  The accident determination unit 21 is a processing unit that specifies a situation in which an accident or a near incident has occurred and stores the situation in the accident situation DB 14. Specifically, the accident determination unit 21 detects the occurrence of an accident from the information stored in the past history DB 13. Then, the accident determination unit 21 identifies the situation assumed to have affected the occurrence of the accident from the situations before and after the occurrence of the accident, and stores the situation as the accident situation in the accident situation DB 14.

  FIG. 8 is a diagram for explaining a method of judging an accident situation. Here, an example focusing on altitude and physical load will be described as an example. As shown in (a) of FIG. 8, when the accident determination unit 21 detects that an accident has occurred when the altitude is 20 m and the physical load is 48.5% from the past history, it extracts the history before and after that Do. Then, immediately before the accident occurrence, the accident determination unit 21 detects that the altitude has dropped by 20 m and the body load has dropped by 13% or more. Then, the accident determination unit 21 determines that the altitude is -20 m and the physical load -13% is a sign of the occurrence of the accident, and "the altitude change, the change in the physical load" = "-20 m or more, -13% or more" As a situation, it stores in accident situation DB14.

  That is, the accident determination unit 21 can detect when the work place has moved from a high place to a place where the altitude has dropped as a sign of occurrence of an accident caused by looseness of mind due to security or the like.

  As another example, in the case of FIG. 8B, which is the history of the work supervisor, when the accident determination unit 21 determines that the altitude is 20 m and the physical load is 489.1% from the past history, the accident occurs. When the occurrence is detected, the history before and after that is extracted. Then, the accident determination unit 21 detects that the physical load has increased by 13% or more, which is 20 m or more higher than the height of 0 m immediately before the occurrence of the accident. Then, the accident determination unit 21 determines that the altitude is 0 to +20 m and the physical load + 13% is a sign of occurrence of the accident, and "the altitude change, the change of the physical load" = "0 m to +20 m or more, + 13% or more" As a situation, it stores in accident situation DB14.

  That is, the accident determination unit 21 can detect a time when a person who does not usually work at a high place works at a high place as a sign of occurrence of an accident caused by tension or the like. In addition, rounding off or rounding off of decimal point can be set and changed arbitrarily.

  It should be noted that the accident situation can also be identified by paying attention to things other than altitude and physical load. For example, while working at an altitude above the threshold before the accident, increase in heart rate before the accident, increase in acceleration before the accident, and safety state ID before the accident are off The total time, etc. may be included in the accident situation. That is, the accident determination unit 21 can detect the accident situation by arbitrarily combining the change in the physical feature, the change in altitude, and the use state of the safety band 1 until the accident occurs.

  The collection unit 22 is a processing unit that collects various types of information from the safety band 1 and the sensor 5. Specifically, the collection unit 22 stores the attachment information and the like received from the safety band 1 in the status DB 16. The collection unit 22 also generates and stores information to be stored in the sensor value DB 17 using the environment information and the attachment information received from the sensor 5. Further, the collection unit 22 combines the attachment information collected in the same time zone with the environment information to generate a past history, and stores the past history in the past history DB 13.

  The determination unit 23 is a processing unit that determines dangerous work among the work of each worker during work from the various information collected by the collection unit 22 and the accident situation stored in the accident situation DB 14. Specifically, the determination unit 23 detects an operation similar to the accident situation from the mounting information and the environmental information collected in real time. Then, the determination unit 23 notifies the warning unit 24 when an operation similar to the accident situation is detected.

  The warning unit 24 is a processing unit that transmits a warning to a worker or a manager who is determined to be in a dangerous operation. For example, when the determination unit 23 detects a dangerous worker, the warning unit 24 transmits a warning to a sensor, a smartphone, or the like of the corresponding worker, and transmits a warning to the management terminal 7 used by the on-site supervisor.

  Here, from the risk prediction to the warning transmission will be specifically described. FIG. 9 is a diagram for explaining the risk prediction. As shown in FIG. 9, the determination unit 23 collates the latest collected information ((a) in FIG. 9) with the accident situation ((b) in FIG. 9) each time it is collected by the collection unit 22. In FIG. 9, the determination unit 23 determines that the latest height is lower than the previous height by 28 m and the physical load is reduced by 13% or more, and thus the determination unit 23 corresponds to the first line of the accident situation. As a result, the determination unit 23 predicts that the worker with the sensor ID “SS1” is in a dangerous situation and notifies the warning unit 24.

  Then, the warning unit 24 specifies from the worker DB 15 the contact point associated with the sensor ID “SS1” notified from the determination unit 23, and transmits a warning to the specified contact point ((c) in FIG. 9). . Further, the warning unit 24 transmits a warning to the management terminal 7 using the contact point of the management terminal 7 set in advance.

  Here, the determination unit 23 can determine that the work is dangerous, not only when the current work matches the accident situation, but also when it is similar to the accident situation. For example, the determination unit 23 can make the determination by giving a certain degree of width to the numerical value of the accident situation. In addition, the determination unit 23 can also determine that the work is dangerous only when the accident state is in agreement and the safety state is off. In addition, when the accident situation is specified by a plurality of items, the determination unit 23 can also determine that the work is dangerous when the current work situation matches a predetermined number or more of the plurality of items of the accident situation. .

  The warning unit 24 can also change the warning level according to the number of matching items. For example, the warning unit 24 forcibly vibrates the vibration of the sensor 5 or displays it on the display of the management terminal 7 when all match, and when all do not match but one or more items match, It is also possible to send an alert only to the management terminal 7.

[Flow of processing]
Next, each process which work judging device 10 performs is explained. Here, identification of an accident occurrence situation and warning determination will be described.

(Specific processing of accident occurrence situation)
FIG. 10 is a flowchart showing a flow of identification processing of an accident occurrence situation. As shown in FIG. 10, when instructed to start the process (S101: Yes), the accident determination unit 21 of the work determination apparatus 10 reads the past history from the past history DB 13 (S102).

  Subsequently, the accident determination unit 21 determines whether or not there is data whose accident flag is ON in the past history (S103). Then, when there is data in which the accident flag is ON (S103: Yes), the accident determination unit 21 identifies and extracts data in which the accident flag is ON and data before and after that (S104).

  Subsequently, the accident determination unit 21 calculates the difference in altitude until the occurrence of the accident (S105), and specifies the change in the physical load until the occurrence of the accident (S106). Then, the accident determination unit 21 identifies the change in the altitude difference and the physical load as the accident occurrence situation, and stores the change in the accident situation DB 14 (S107).

  Thereafter, the accident determination unit 21 returns to S103 and repeats the subsequent processing. In addition, the accident determination part 21 complete | finishes a process, when there is no data whose accident flag is ON (S103: No). Also, this process can be performed periodically, or can be performed according to an instruction from a manager or the like.

(Warning judgment processing)
FIG. 11 is a flowchart showing the flow of the warning determination process. As shown in FIG. 11, when the sensor data and the like are received (S201: Yes), the collection unit 22 of the work determination apparatus 10 stores the received sensor data and the like in the corresponding DB (S202).

  Then, the determination unit 23 compares the previous sensor data with the latest sensor data, and specifies the change in the altitude difference and the body load up to the present time (S203). Thereafter, the determination unit 23 determines whether or not the identified height difference and the change in the physical load match the accident occurrence status (S204).

  Then, if the identified height difference and the change in physical load match the accident occurrence status (S204: Yes), the warning unit 24 identifies the contact point of the corresponding worker from the worker DB 15 (S205), and the corresponding A warning is notified to the worker, management terminal 7 or the like (S206).

  In addition, when the change of the height difference and the physical load which were specified does not correspond with the accident occurrence condition (S204: No), it returns to S201 and the process after it is repeated.

[effect]
The work determination apparatus 10 is effective by generating data at the timing when the state of the worker changes in response to changes in past accident cases and states, and managing the entire history as one analysis target time series data. It can track changes over time. For this reason, the work determination apparatus 10 can predict according to the change of the safety information from the past to the future, and can predict the degree of danger of the worker in real time.

  In addition, since the work determination apparatus 10 detects a change in body load or a change in altitude before and after an accident, physical changes affecting the occurrence of an accident can be identified in a time series, and an accurate feature of the accident situation Can be realized. In addition, since the operation determination apparatus 10 identifies the time at which the tension sensor is activated as the time of the accident, it can accurately identify the time of the accident.

  Although the embodiments of the present invention have been described above, the present invention may be implemented in various different modes other than the above-described embodiments. Therefore, different embodiments will be described below.

[Identification of the accident occurrence situation]
In the first embodiment, an example in which attention is paid to the height difference and the change in the physical load has been described, but the present invention is not limited thereto. For example, in addition to changes in altitude and changes in physical load, changes in heart rate, changes in acceleration data, working time up to the current working place, working time immediately before the current working place, and rest It is also possible to identify the accident occurrence situation by paying attention to the later elapsed time and the like.

  Furthermore, the work determination apparatus 10 specifies the work environment at the time of the accident occurrence by using various sensors capable of measuring weight etc., a load sensor attached to shoes, an image captured by a camera worn by an operator, etc. Focusing on these, it is also possible to identify the accident occurrence situation. For example, the working environment includes the size of a scaffold, the presence or weight of a load, and the work content such as work on a ladder or a stepladder. By doing this, the work determination apparatus 10 can identify an accident situation in which an accident is associated with a physical change that can not be confirmed by visual observation on the site or by visual inspection by the on-site supervisor. Not only accidents due to caution, but dangerous work can be detected in advance.

Work Plan
Moreover, although the example which specifies the worker who is performing the operation | work similar to the accident occurrence condition in real time was demonstrated in Example 1, it is not limited to this. For example, the work determination apparatus 10 can specify the dangerous work before the start of the work by specifying the work similar to the accident occurrence situation from the work plan.

  Here, an example in which dangerous work is detected from the work plan will be described using an example in which “altitude change, working time” = “− 20 m, 8 minutes” is specified as the accident situation. This accident situation indicates that the work “altitude lower than −20 m and the work time before the altitude fall is longer than 8 minutes” is highly likely to occur.

  FIG. 12 is a diagram for explaining an example of detecting a dangerous work from the work plan. The work determination apparatus 10 receives a work plan shown in FIG. As shown in FIG. 12, the work plan includes work contents in which "work day, worker, work place, altitude, work time" are associated. Then, from the work plan shown in FIG. 12, the work determination apparatus 10 confirms whether there is a work corresponding to “a work at which the altitude is lowered by −20 m or more and a working time before the altitude is lowered by 8 minutes or more”.

  Then, the work determination apparatus 10 transmits a warning to the on-site supervisor or the manager because there is a corresponding work in the 2017/12/01 patent taro construction ○. By doing this, the work determination apparatus 10 can identify a dangerous work before the start of the work and can firmly suppress the occurrence of an accident.
