Beirut Chemical Explosion Case Study

How Vismo was used by one client to successfully locate employees immediately following the recent Beirut chemical explosion.

Company Profile

A large American multinational oil and gas corporation, who has been a client of Vismo for a number of years deploys the Vismo App on Smartphones devices to monitor and protect employees, executives and expatriates when travelling around the world for business. The company has a strong understanding of its legal & moral obligations towards its global staff and a dynamic appreciation of the risks staff can face.


On 4th August 2020, there were two major explosions which killed more than 200 people at the port of the city of Beirut, the capital of Lebanon. The disaster was caused by an extensive fire at the port, which spread to the roof of the warehouse which stored ammonium nitrate. As the news broke across the world, it was crucial for the client to locate and ensure the safety of their travelling employees and expatriates within the Beirut area as soon as possible.


Upon notification of the incident, the client used the Vismo Secure Portal to expeditiously locate all travellers in the nearby vicinity of the explosion. Using Vismo Mass Notification, the client was able to effectively communicate crucial information and alert the identified travellers within the Beirut area of the situation, with message response options. Fortunately, all employees within the affected area were in areas of safety and were able to confirm their current status from within the Vismo App.


Using the latest  tracking technology,  the Vismo Global Traveller App  operates  in the background of the device, while automatically reporting precise location fixes to the Vismo Secure Portal. The live tracking updates helps automatically eliminate those employees who were not in the area without needing to indivually contact them; imporving organisational efficiencies while freeing up vital resources. This location information was vital in understanding which employees were in the Beirut area and ensured that the client could communicate with and establish the safety of their employees. Not only did Vismo enable the client to locate their employees within the affected area, but it also ensured they had resources to effectively broadcast crucial information about the explosion using Vismo Mass Notification. By Utilising the Vismo solution the multinational client was able to successfully locate, monitor and communicate with all employees in and around the Beirut area following the disaster while meeting their organisational Duty of Care, all from within one powerful platform.

Overcoming Lone Worker Privacy Concerns

Privacy and Data Protection is an ever-increasing concern for both individuals and organisations. Most recently, these concerns have been highlighted with the roll-out of various government-led COVID-19 tracking applications. Whilst some people are amenable to being tracked, others find it an infringement of their privacy and even as far as a breach of human rights. Vismo takes the privacy of its customers seriously; maintaining your trust is paramount to us. This article explains how Vismo has overcome Lone Worker privacy concerns without compromising the security of personal data.

What is the purpose of a Lone Worker App?

A Lone Worker App is a tracking solution designed to protect employees who work without close or direct supervision.  If there is an emergency, Lone Workers are able to alert their employers who can assess the situation and follow the required escalation process. A Lone Worker App enables organisations to meet their legal and moral Duty of Care responsibility in protecting employees’ health, safety and welfare while at work.

How does the Vismo Lone Worker App work?

The Vismo Lone Worker App is compatible with Smartphones and Tablets operating on iOS and Android systems. Using GPS and other technologies from the device allows Vismo to accurately determine a Lone Workers’ location and this information automatically is sent to the Vismo Secure Portal for monitoring purposes.

What Information Does Vismo Collect About You?

To operate correctly, the only information that is required is location data; all other information is optional. Vismo generates a unique anonymised identifier for each device and this identifier may then be associated with certain personal information in accordance with the data handling policy of the individual customer. Registration information will be subject to and protected as per our Privacy Statement. Our Privacy Statement and our practices are designed to provide a globally consistent level of protection for personal information all over the world, even in countries whose laws provide less protection.

Is My Data Secure?

Security and data protection are the upmost importance concern and maintaining your trust is paramount to us. Vismo is hosted by Microsoft Azure Cloud to protect personal information and to maintain its accuracy, encrypting sensitive personal information when transmitting such information over the Internet. Vismo and Microsoft Azure are both ISO 27001 certified; the gold standard for Information Security Management Systems. Vismo adheres to the General Data Protection Regulation (GDPR) which is the EU law on data protection and privacy policies.

What Happens If a Lone Worker Doesn’t Want to Use a Tracking Device?

Organisations can only encourage Lone Workers to use a tracking app and they must voluntarily consent to be tracked as part of their personal safety and organisational Duty of Care obligations.

To encourage acceptance of tracking devices by Lone Workers, Vismo has integrated Privacy Mode capabilities into the Lone Worker app to protect Lone Workers personal privacy without compromising safety. Privacy Mode allows Lone Workers to choose when to be tracked, whilst keeping the Panic Button feature. If a Lone Worker faces an emergency or situation of duress, they can activate the Panic Button from within the Lone Worker App and this will notify monitoring teams while revealing their location to provide peace of mind for employees as they work alone.

Introducing Mass Notification and Incident Management Capabilities into Vismo

Multi-award-winning global tracking company Vismo has launched Mass Notification and Incident Management Capabilities into the new and improved Mobile Tracking Apps and Secure Portal. Utilising state-of-the-art tracking technology and the latest messaging capabilities, Vismo enables organisations to efficiently communicate critical information to a diverse audience from the Vismo Secure Portal. The additional functionality further demonstrates the commitment the company has to deploy the latest technology to enhance its solutions and better serve its global client base.

In the event of a critical situation or emerging risk, rapidly delivering crucial information to the right audience is imperative to employees safety. Vismo provides a secure, scalable and reliable system to enable enterprises to send two-way notifications to individuals or groups to keep them informed before, during and after critical events.

Mass Notification

How does Vismo Mass Notification Work?

Using the Vismo Secure Portal, a Vismo Mass Notification can be created from predefined options or tailored to an individual situation. Mass Notifications are sent to the required audience using 4 channels; SMS, Email, In-App and Phone Calls. Using multi-path Notifications ensures communications can be maintained even in the event of outages or network contention.

Two-way Mass Notifications can be sent with coded response options, allowing employees to quickly reply with their relevant safety status. Notifications can be looped until a response is received from an employee with abilities for employees to update their safety status as they become more aware of the developing situation. Using the Vismo Secure Portal, operations teams can monitor employees responses along with their last known location and act upon it if required.

Combining Mass Notifications with Incident Management

Integrated live intelligence feeds from external sources into Vismo enables operations teams to monitor and manage travellers in incident areas using one platform. Incident Management enables operations teams to identify travellers efficiently in a crisis based on geographical location; informing them of the situation using Mass Notification.


An Incident Dashboard displays the incident location with the identified travellers in the location. All travellers responses from the Mass Notification with their safety status can be viewed here. If a traveller enters the identified incident location, they will also receive the Mass Notification informing them of the situation.

The New Secure Portal and App

At the end of last year, Vismo introduced the new and enhanced Mobile Tracking Apps and Secure Portal and with increased functionality and enhanced user experience.  The new Secure Portal introduces intuitive search capabilities of travellers locations including Points of Interest, Geo-fences and landmarks from a single search bar. In addition to the new Secure Portal, Vismo has launched an updated and improved version of its long-standing user tracking Application Global Traveller to provide users with a more consistent, unified and cohesive Vismo platform.

Praesidio Ltd Case Study

Company Profile

Praesidio Ltd is a specialist security, emergency response and training provider, offering a wide range of solutions to suit a varied client base. Headquartered in the UK but with global reach, Praesidio provides support to the oil and gas sector internationally, with a strong operational presence in Africa.

Business Situation

An intrinsic element of the commitment to safety and security is ensuring that all organisations comply with the legal and moral duty of care to their personnel. At Praesidio, that commitment to safety and security commences when personnel depart the UK, continuing throughout the duration of their time overseas. Praesidio required a secure tracking and monitoring solution and after extensive due diligence selected Vismo as their tracking partner.

The Solution

Using the Vismo Global Traveller App downloaded to travellers’ smartphones, has enabled the Praesidio Operations Team to track and monitor clients travelling overseas, whilst aiding in planning travel and security arrangements at their end destinations before their arrival. Praesidio makes use of the range of features Vismo offers, to help in protecting their clients whilst travelling abroad.

Utilising the ‘Check-In’ functionality allows clients to notify the Praesidio Team when they arrive and depart key destinations or locations, during their travel or time overseas. The ‘Country Change’ feature automatically notifies administrators when clients arrive in a new country. These features ensure the Praesidio Team can monitor key movements in the client’s schedule, whilst acting as an added safety layer. Should a ‘Check-In’ be missed or late, the team immediately responds and follows the required escalation process.

The Vismo Secure Portal has incorporated ‘Points of Interest’ (POI’s) to define relevant locations on the map. In preparation for a client’s trip, the Praesidio Team identifies locations for clients to stay en-route to their end destinations, as well as identifying key infrastructures such as Embassies, hospitals, police stations and airports.  Geo-fences are invisible borders placed around high-risk and safe areas. Geo-fences help to ensure that should a client accidentally find themselves in such an area, the Praesidio Operations Team is immediately alerted and can intervene and direct them to safety.

Customer Quote

The global security climate can be volatile, unpredictable and change without warning. Through the Vismo Secure Portal, we can respond to this changing climate by altering routes, journeys or destinations to ensure our clients are not exposed to unnecessary risk. Using Vismo, we have found that during emergency incidents overseas, we can monitor and coordinate personnel in real-time as the situation unfolds, to ensure they reach safety, in a fraction of the time than we have previously.

The Vismo Global Traveller App has been designed so that it can be personalised to suit each client’s individual needs, whilst incorporating essential functionalities in case an emergency situation arose. Within the App, we have been able to add a direct link for our Incident/News Feed from the Praesidio website; ensuring our clients receive news directly from us. We find that because we can configure the Vismo App to our clients’ specific needs and our company profile, clients are more likely to interact with the multitude of features available to them within the App.

As well as the key safety features you would expect from a tracking application, including Live & Historic Location Updates, Panic Alerts and Geo-fencing capabilities, Vismo has a range of additional functionalities to aid with tracking and monitoring clients overseas. We can communicate directly with our clients using Vismo Encrypted Messages and Mass Notifications, which again is reassuring to know that ‘One App Does All’; it alleviates the requirement for contact through multiple platforms.”

What is EVV?

What is Electronic Visit Verification?

Electronic Visit Verification (EVV) is a method used to verify home healthcare visits in the United States.

Part of the 21st Century Cures Act passed in 2016, EVV has been introduced to reduce fraudulently documented home visits while ensuring people receive the documented care they need. In turn, this helps verify that the services billed for are actual visits made.

All US states are required to implement EVV for home care agencies that provide personal care services (PCS) by January 1, 2020, and home health services on January 1, 2023, or risk having their medical claims denied. Many states already have EVV implemented.

How to Comply with EVV Legislation?

The federal government has suggested several possible methods to comply with EVV legislation. One of the most popular methods that ensure home care agencies adhere to EVV is through using a Lone Worker tracking app that uses location services on the caregiver’s cell phone. Most states are opting for mobile solutions because people no longer have landline phones and fixed devices are more costly and burdensome to implement than mobile apps.

The Vismo Lone Worker Solution

The Vismo Lone Worker Solution uses GPS technology to locate caregivers using their smartphone or device, as they travel between jobs and at patients’ homes. When arriving at a patient’s home, caregivers can check-in using the Vismo App. This will verify the date, time and place that they started their home healthcare visit. Once they have completed their visit, the caregiver can check-out from within the Vismo Lone Worker App, which will record the information about the job in compliance with EVV and store it on the Vismo Secure Portal.

The Vismo Lone Worker App features an integrated Panic Button to aid with monitoring caregiver’s safety if they face an emergency or a duress situation. Once the Panic Button is activated, monitoring teams are automatically notified of the situation. Vismo then covertly records audio which is available for playback to help monitoring teams to further understand the situation and follow the required escalation process.


Features of the Lone Worker App:

  • Yellow Alert with Timed Check-ins
  • Panic Alert with Covert Audio Recording
  • GPS Tracking with Location History
  • Two-way Encrypted Messaging
  • Mass Notifications
  • Geo-Fencing
  • Assignments
  • Personalized Interface


The deployment of the Vismo Lone Worker App on a caregiver’s smartphone will allow Home Care Agencies to meet the EVV mandate and in addition improve communications, enhance business process and most importantly, improve the safety of their caregivers as part of their organizational duty of care.

Monitoring COVID-19 and Employees with Vismo

Vismo has integrated COVID-19 data into its tracking solution enabling clients to actively monitor employees in relation to outbreaks.

Vismo has integrated the latest COVID-19 data from Johns Hopkins University into the Vismo Secure Portal, as a Point of Interest (POI) layer. This information is available to all Vismo clients free of charge.

Johns Hopkins University is actively monitoring the COVID-19 pandemic, updating the information in real-time on the number of cases, deaths and recovered patients, in affected countries and by States in the US.

By incorporating this data into the Vismo Secure Portal, it enables organisations to display the exact location of an employee with the latest COVID-19 statistics overlaid on their position.  In addition, having the ability to track an employee who may have become infected, and then the potential to trace any contact with another colleague could be helpful in isolating the spread of the virus.


Whilst a third of the world’s population is currently in lockdown, and the start of international business travel unlikely in the immediate future, keeping a track of virus numbers in countries when travel restrictions are lifted may influence a decision to allow an employee to travel or not.

Johns Hopkins University

The COVID-19 dashboard map was built by Professor Lauren Gardner at Johns Hopkins University back in January when the outbreak was primarily in China, to track the spread of the disease as it unfolds from transparent data sources.

Collecting information from a variety of sources including the World Health Organisation (WHO), European Centre for Disease Prevention and Control, and the National Health Commission of the People’s Republic of China, enables Johns Hopkins University to effectively relay the latest information in real-time.

Actively monitoring the COVID-19 pandemic, Johns Hopkins University are reporting on a range of information including the number of cases, active cases, deaths and recovered patients, in affected countries and by States in the US.

Integrating the latest COVID-19 data from Johns Hopkins University into the Vismo Secure Portal enables clients to visualise cases and monitor employees’ locations relative to the outbreak.

For more information about the integration of COVID-19 data into Vismo, contact a member of the Vismo team.

Protect Individuals Travelling to Japan with Vismo

Returning to Japan for the first time since 1964, the countdown is on until Tokyo hosts the biggest sporting event in the world. Global tracking specialist Vismo is set to provide organisations and travellers with essential monitoring and tracking capabilities. With the eyes of the world on Tokyo, focus must be placed on security for the large-scale event.

Before travelling abroad, travellers should conduct research in order to understand any potential cultural differences, as well as any possible risks in the target destination. Japan is one of the safest countries in the world. Yet with natural disasters making the headlines, should travellers and attendees be cautious of their safety? In wake of recent natural disasters event organisers are taking extra precautions to ensure travellers feel safe at the Games. According to media reporting, attendees can feel reassured in the knowledge that all venues have been constructed so  they are seismic resistant and comply with strict Japanese building regulations. Venues also have specialist evacuation plans as an added precaution should natural tremors occur. Attendees’ safety is the primary concern for event organisers, who have even resulted in fail-safe testing their venues through controlled simulated earthquake testing.

While Japan is pulling out all the stops to safeguard attendees and provide ease of mind, Vismo advises travellers to extend further diligence to their own individual safety.

Vismo Reaches New Heights at Ol Doinyo Lengai Volcano, Tanzania

Award-winning global tracking company Vismo, reached new heights in Tanzania, proving pivotal to PhD student Kate Laxton from UCL who travelled to the country to complete a research project on the Ol Doinyo Lengai Volcano.

Aware she would be out of her usual terrestrial network coverage for over a month, Kate took the Iridium Extreme Satellite Tracker from Vismo. Taking full advantage of the Vismo solution, Kate was tracked and monitored for her entire trip and communicated with UCL mainly via text message upon the satellite device. As the only satellite network with 100% global coverage, the Iridium Extreme Satellite Tracker ensured Kate would stay connected and relay any important information to the team at UCL in London.

The Iridium Extreme Satellite Tracker is fully integrated into the Vismo platform allowing users to benefit from the range of features within Vismo including panic alerts and geo-fencing.

Kate 1

Ol Doinyo Lengai is the world’s only remaining active carbonatite volcano, and Kate’s expedition was to research and understand how it formed, why it is still active and what caused it’s magma to be so unique as the coldest lavas on earth at less than 600 degrees C. Twelve years had passed since the last sample was collected and only 2 weeks after the sample was taken, the volcano unexpectedly exploded. Taking precautionary measures, and not wanting to get caught up in any physical danger unable to communicate with anyone was the reason Kate knew she needed a satellite device upon the trip.

Whilst there, Kate was supported by Dr. Emma Liu (UCL), Mr. Arno Van Zyl (Vertica Ltd) and local guides, as well as the Geological Survey of Tanzania (GST) and the University of Dar Es Salaam, to take much needed samples of the rare natrocarbonatite lava from the Ol Doinyo Lengai Volcano.

The group collected six freshly erupted natrocarbonatite samples, six MultiGAs traverses, two MultiGAS dips, three nights of thermal imaging, three drone-bases DEMs and eight tephra samples.

After Kate become concerningly ill during the first ascent of the Ol Doinyo Lengai, the Iridium Extreme Satellite Tracker really came into its own. It was the critical tool which allowed her and the team to connect with emergency medical services in the UK, saving the need for a medical evacuation.

Kate said about her trip:

We selected Vismo because of its track record over many years in providing mobile comms for individuals and organisations around the world, some of them in the most demanding situations, from mountains in the Himalayas to remote rivers in South America. Those comms include Vismo’s technical expertise and server hardware, which together enabled the precise tracking of our location for use by our security team, and two-way communication with UCL.

For the most part, we ended up using the satellite phone to update UCL via text message and perhaps more importantly for morale, occasionally snatching a moment to call home. Although, after becoming concerningly ill and deteriorating rapidly during the first ascent of Ol Doinyo Lengai, I was truly grateful to have a phone powerful enough to connect me through to emergency medical services in the UK, which saved me opting for a medical evacuation as my last resort.

When we arrived at the summit, we were fortunate to find that the activity on the crater floor consisted of lava flows, an open lava pool and one spatter cone, giving us ample opportunity to proceed with our sampling strategy.

By the end, we had spent eight days and nine nights at the summit, giving us enough time to collect six freshly erupted natrocarbonatite samples, six MultiGAS traverses, two MultiGAS dips, three nights of thermal imaging, three drone-based DEMs [digital elevation models] and eight tephra samples, all the while smashing our targets with a whole load of brilliant teamwork.
