Lone Worker

RASOR is a device to help companies achieve greater regulatory compliance while enhancing the health and safety of field operatives and lone workers.






It’s an ideal device for employers who have multiple risks being monitored on disparate systems or have lone or mobile workers at risk from HAV exposure, while the Tool Training App helps optimise in real-time tool operator productivity and risk.   

RASOR captures real-time, multiple workforce risks and can support remote and lone workers with location information, slips/trips and fall detection.
  • Real-time location & visibility of workers’ HAV exposure risk - read more
  • Additional third party sensors can be monitored simultaneously
  • Seamlessly aggregate, visualise and manage disparate risk data via a single operational view immediate alerts for field and remote supervisor intervention.
  • Alarms for immediate support to panic and man down 
  • Tool operator training aid  




Multi-purpose device to support a number of functions & roles with the flexibility to allow you to configure it to your specific needs utilising some or all of its capabilities.. 


RASOR - how it works



Lone workers can range from a construction worker alone for only a few minutes, a grounds maintenance crew member working out of sight, to a utility worker responding to call outs.  
RASOR can support these activities and associated risks, by monitoring slips, trips and falls, man down alarms and panic situations for complete piece of mind. 
Utilising mobile phone signals, RASOR can communicate an employee’s GPS tracked location and via Reactec’s Analytics, trigger a range of response level service packages - 24/7 coverage for a tailored suite of alarms;  
  • Check-in and Check-out; 
  • Automatic Man-down; 
  • User driven Panic. 


The Tool Training App means supervisors can better manage productivity and risk than previously considered possible. 
By combining the RASOR training aid and HAVwear supervisors can proactively optimise tool choices and usage by training colleagues to: 
  • Improve operator tool technique
  • Better assess tool condition
  • Ensure the best tool for the job
Assigning a RASOR to either a field supervisor or team member, the RASOR will automatically gather live exposure data from all their teams’ health risk sensors within range, including but not limited to Reactec’s HAVwear.
The RASOR user and remote management will be automatically alerted to any exposure breaches for immediate over the shoulder intervention.
The RASOR transmits exposure data along with location information to the cloud based Reactec Analytics every 15 minutes so remote supervisors can have full visibility of their team’s location and exposure risk levels.


By assigning a RASOR to a high risk individual exposed to multiple risks, such as noise, gas and dust the RASOR will gather data from any risk sensor on the individual and display it on RASOR as a single connected worker device. They no longer need to check multiple sensors whilst working or wait till the end of their shift or even longer to understand their exposure.
The data from multiple sensors aggregated through RASOR is automatically transmitted to a single powerful Analytics platform every 15 minutes. 
Simply view all of your assimilated exposure sensor data in a single Analytics, for a holistic view of employee risk in order to develop more effective risk control measures.

Reactec’s Analytics

RASOR analytics

Reactec’s Analytics is the heart of all Reactec’s technologies. RASOR automatically collates and transmits data to the Reactec Analytics so organisations can benefit from receiving live, location determined health risk data from the field. RASOR turns the Reactec Analytics into a single Analytics platform for viewing multiple risk data within a standardised interface removing the need to collate data from separate sensors and understand their individual reports. 
Web hosted, the reports are designed to highlight what matters most in turning your gathered sensor risk data into actionable intelligence. Available 24/7, GDPR compliant and securely hosted by Reactec.
RASOR is a flexible multi-purpose device designed to improve risk management & compliance while enhancing the health and safety of high risk individuals.
If you have employees exposed to HAVS risk working in teams or alone, in construction, manufacturing, rail, utilities or facilities management then contact Reactec on how you can improve your work environment and occupational risk and compliance.

AMEY North Lanarkshire - Gerry Kennedy, Roads Manager

“Before the HAVmeter, we relied on manual input, with a guy basically using his memory at the end of the day for the time that he has spent using vibratory tools. With the HAVmeter, we have an accurate, user friendly piece of kit which allows us to manage HAV more easily. It really is a Health and Safety Management tool. We have been able to make major savings through cutting out administrative costs.”
