In the realm of workplace safety, the risk of falls looms large as a potential threat to both employees and employers alike. The fear of an unnoticed fall leading to serious injury can be a constant worry for those working in isolated or hazardous environments.

How can one ensure prompt assistance in such situations? Enter the Mercari Lone Worker Alarm with integrated Auto Serious Fall Detection – a cutting-edge solution designed to provide peace of mind and immediate response to falls, regardless of whether they occur in bustling workspaces or remote locations.



Falls from height, and falls on the same level have been identified in various statistics globally as a significant cause of harm

Slip, trip and fall injuries cost the UK approaching 1 billion pounds per year.

37% of all reported workplace injuries were as a result of a slip, trip or fall, with 28% of all fatalities in the workplace being caused by a slip, trip or fall.

On average approximately 50 people die each year from a slip, trip or fall and a great many more are injured – some critically.

The severity of injury varies between the type of accident with perhaps predictably the most fatalities being attributed to injuries from falls. Of the 45,000 injuries reported under RIDDOR (Reporting of Injuries Diseases and Dangerous Occurrence Regulations), 43 these of these involved fatalities. 88% of these fatalities were attributed to falls, 58% of the fall fatalities being sustained from heights in excess of 2 meters, with the remaining 12% of the fatalities being caused by slips or trips.

95% of the fatalities were sustained by men which can be explained by the largely male-dominated construction industry – roofing and painting / decorating being particularly high risk. 59% of all fatalities were in the construction industry, and there were also twice as many non-fatal major fall injuries in this sector than the next highest sector.

The incidence and severity of injury increases in a roughly linear fashion with the age of the person involved – approximately twice as many incidents being in the 60-64 age group as the 16-19 year old age group. A third of worker fatalities were in the 60-64 age group even though they make up only 13% of the workforce.

Fall Detector

This device has a sensitivity adjustable, automatic fall detection built in, detecting serious falls.

To activate fall detection / Man down automatically, it requires:

– 1 meter or more sudden drop in altitude 

– Angle change like falling backward or forwards

– An impact that’s could cause injury or incapacitation

If the parameters or sensitivity has not been met (like falling onto soft surfaces like grass or a short fall off a chair, it should be determined that the user can activate the SOS button themselves. If parameters are met, the device will automatically start an emergency sequence of SMS to nominated contacts (and start calling out in sequence if desired)

Man down alarm can be set for ‘no movement’ too. In the event the device doesn’t sense movement for a predetermined period of time, it alerts the nominated emergency contacts that the device has been stationary.

If you are worried about falls yourself, or worried for someone who may be prone, an alarm with serious fall detection may be of assistance.

Sensitivity can be adjusted and fall detection can be turned off when required.
