Safety / Risk Prevention
Secure your workstations at risk
Secure your high-risk workstations, reduce exposure to accidents
Are you a collaborator?
An employee under the influence of alcohol or drugs in a high-risk position is a danger that you cannot afford to ignore.
As a safety manager, your priority is clear: reduce exposure to risk in all positions where a loss of vigilance or an impairment of abilities can have serious consequences, for example when driving vehicles, machinery, working at height, electrical authorization, driving industrial machines.
Regarding road safety alone, more than a quarter of road accidents today are linked to the use of psychoactive substances, a finding that led us to create a unit dedicated to this subject.
Medisur has been designing its own screening devices since 2015, has held the status of a French reference laboratory since 2016, and supports safety managers in transport, industry, construction and logistics in setting up reliable protocols, adapted to each category of risk position.

Our range of tests, designed by our teams
One Test
Targeted at cannabis (THC), the most frequently consumed psychoactive substance in the workplace, with a fine detection threshold of 15 ng/ml allowing for the identification of recent consumption.
Multi-Drug
Simultaneous analysis of six families of substances (cannabis, cocaine, opiates, amphetamines, methamphetamines, synthetic cannabis), with two threshold levels depending on whether your protocol aims for a classic prevention approach or stricter control.
Easy Test Plus
An exclusive on the French market: from a single saliva sample, this test simultaneously covers the six families of drugs and alcohol, with a reactive buffer signaling a positivity from 0.2 mg/ml of saliva.
Chemical breathalyzers
The only device that allows reading both regulatory thresholds simultaneously (0.2 g/l for novice drivers, 0.5 g/l for all users).
All our saliva tests are for single use only, comply with the legal requirements of the Council of State, and feature a reverse display guaranteeing the confidentiality of the reading by the operator—a negative result is obtained in less than 2 minutes. To prevent any disputes, our methodology relies on the systematic use of two separate physical tests.
The legal framework for disputes
In the event of a dispute regarding a positive result, the employer is required to offer a second medical opinion: an immediate saliva sample, sent to a COFRAC-accredited laboratory, the only body authorized to produce a legally binding report. We provide a complete second medical opinion kit, delivered to our partner laboratory. You will receive an official report electronically on the day of receipt by the laboratory, allowing you to initiate disciplinary proceedings with full legal certainty.
Risk coverage that goes beyond addictions
Since the creation of our Health Hub in 2019, your QWL (Quality of Work Life) and risk prevention roadmap is no longer limited to addictive behaviors. We also work on:
- Road hazard — a dedicated Occupational Road Risk training course (3.5 hours in person or 2 hours remotely, Qualiopi certified), created in response to the observation that more than a quarter of road accidents are linked to the use of psychoactive substances
- Safety workshops for your Safety Day — Rollover car, frontal impact simulator, reaction timer, interactive digital wall, alcohol karting: concrete activities to make a lasting impression during your awareness days
- Cardiovascular prevention — Screening for risk factors for jobs involving high physical demands or shift work
- Pink October and Movember — screening and awareness-raising actions that can be integrated into your health prevention calendar
- Gestures and postures, first aid — practical workshops adapted to the at-risk positions identified in your DUERP
