Each year the contribution rates are determined by the CRAMIF or CARSAT services and defined by a ministerial order. Objective to enable companies to contribute (employer contribution) and protect employees.
This contribution rate varies depending on the size of the
(national workforce), the business sector (risks incurred by the
employees), the loss of the institution concerned. The rate is given
every year to businesses.
Each activity has a “risk code” determined by
based on the main activity for the largest number of employees in the
the company. 2 digits 2 letters (ex 55 3BC), 208 nomenclature risks
in 9 sectors. This code should not be confused with the APE code (rather
economic indicator). the risk code determines the risk incurred by the
There are 3 types of pricing:
Collective pricing for companies
less than 20 employees. The rate is defined collectively according to the
of sectoral elements
Individual pricing for companies
250 employees. The rate is calculated from the elements of the
Mixed pricing for companies between
21 and 249 employees
The purpose of the calculation method is to rely on the
the company’s disaster. In this way there is now, since 2018, a
a real financial impact on the contribution rate in a sense as in the
the other to “reward” the efforts and actions of

The installation of sensors in a parking lot under terrain for example
allows you to measure in time the peaks of pollution and to trigger the
real-time breakings. Objective: to ensure user comfort

to inspect parks for facilities that are not readily accessible. In
Association artificial intelligence it is possible to raise several
sites and to build models to see the evolution of the structure on the
a certain period of time and bring alerts when you think there is a danger

For several months we have been talking about our solution
software and its technological aspect. Its strengths for ergonomists.
But did you know that ergonomists do not have the exclusive use of
KIMEA. The tool can also help other trades. We're explaining this to you.
Are you a prevention technician?
During training at the future workstation, KIMEA will be interesting to learn the right gesture. It will bring a playful point of view for sometimes long courses. The impact of the images is stronger and guarantees better memorisation on the part of the employee.
Are you a work doctor?
The overall view of a post and the scores by articulation will allow you to better target the workstations on which an operator can resume his activity in the event of a contraindication or in case of return to work.
Are you a method engineer?
KIMEA allows you to have real-time data relative to the prescribed. This will allow you to easily identify if there is a gap between the prescribed range times and the actual time. In addition, when you return each task for each workstation, you will be able to create a detailed activity diagram (time, MSDS risks, solicited joints,…)
Are you a production manager?
The tool allows you to do a mapping of workstations and to have a global vision. You will be able to make rotating loops of your collaborators who do not solicit the same joints. And compared to competing tools, we guarantee you a time saver. Indeed, without sensors or combinations, there is no need to stop the production line several minutes to start analyzing. Finally you can have a global view of your site from a physical and biomechanical point of view.
Ergonomics is the the science of adapting work to human. it is looking for the best possible match between the physical and mental characteristics of the workers and production targets.
The ergonome analyzes the
working situations with a view to transforming them to:
health of people
take a turn for the better
their working conditions
take a turn for the better
the quality and efficiency of production
To do this, the ergonomist carries out a systematic analysis of a holistic approach that takes into account all the elements that make up a working situation. This analysis is multidisciplinary and involves the knowledge of the ergonomist in various disciplines (biomechanics, psychology, Physiology, sociology, technology, etc.). The approach is also participatory because the ergonomist will question and invite the persons concerned to express their points of view of their activity. The elements collected will be integrated into the analysis Global.
But it must be before ergonomist has an approach that is “realistic” because it should be interested in the activity as it is actually exercised, and thus differences between this actual work and the one prescribed by the company.
When capturing the movements of the operators, KIMEA realizes in real time a 3D digital twin of the operator. This week we propose you to revisit this notion of digital twin and especially its contribution in ergonomics.
“When it comes to the digital twin, it all started in the aerospace industry. In order to realize complex tasks, spacecraft are subject to high loads and severe operating conditions, this, during long periods. Since then, digital twins of space stations and space craft have been created to simulate physical reactions, or monitor the functioning of systems, and ensure the safety of crews during exploration.”
The purpose of the digital twin is to create a digital duplicate of an object, a building or a person. It is a kind of virtual copy of the physical world in order to identify problems, to understand how a complex system works.
In our case, which is the one of ergonomics, the digital twin is an aggregate of data that reflects as accurately as possible the gestures and postures filmed. It facilitates access to data (articulatory angles,…). The twin integrates all the necessary biomechanical data and can be customized according to the person’s “history” (weight, height, loads, etc.). With the digital twin, we are then able to predict the areas of the body at risk in terms of musculoskeletal disorders.
Although the algorithms allow accurate measurement of the main joints of the body, wrist movements are still very difficult to obtain reliably and robustly. Indeed, hands often interact with objects/tools during work tasks, which makes it very difficult to capture them with a single camera. Moreover, low-intensity wrist angulations remain highly impactful in measuring the risk of MSDs, hence the need to obtain a very accurate assessment of this joint.
To remedy this lack, the Moovency scientific team has developed “connected mittens” that slip under the collaborators’ work gloves and automatically obtains this missing information.
We have selected a system which fits with our values (simple to use, non-binding, accurate and robust). To do so, we started by creating a state of the art of the various existing solutions . In the light of this study, we selected the so-called technologie dite des centrales inertielles. Those sensors are composed of accelerometers, gyroscopes and most often accompanied by magnetometers to obtain segment orientations. Due to their small size and portability, they are increasingly used in the study of movement. [Jasiewicz2007, Kavanagh2008].
In order to guarantee the correct placement of the sensors we have made a mitten with pockets to insert the sensors with a predefined and anatomically valid placement. This mitten device therefore allows optimal placement of the sensors without prior anatomical knowledge.
KIMEA measures the joint angles of the upper limbs, neck and trunk with reference to standards to perform an MSD risk rating based on the RULA (Rapid Upper Limb Assessment) grid. Repeatability is taken into account as well as the charging port. The method is designed to analyse each body part separately.
We wanted to go further than this widely used method with the introduction of dynamic quotation. Therefore, we propose to visualize at each moment of the work cycle the evolution of the MSD risk and the time spent at each risk score.
Until now, this risk was calculated statically from a few representative postures. The static rating therefore does not distinguish an operation with 3 minutes of high joint stress over 15 minutes of work and another with 10 minutes of high stress over the same cycle time.
With our dynamic quotation you no longer have to choose a posture that is supposed to represent the entire task. The dynamic scoring restores the actual weight of MSD risk exposure over the entire cycle time assessed. The MSD risk is placed at its proper importance in relation to the duration of exposure. KIMEA therefore allows you to prioritize according to:
The company is required by the general safety obligation to assess the potential risks and take all necessary measures to ensure the safety and protect the health of its company’s employees. For this purpose, an Interference Risk Assessment Document (DUVRI) must be drawn up and kept updated. This document must identify all risks to the personnel health and safety and the action plan to inform and prevent them.
If no format is imposed, the Labour Code states that the first step is to establish “an inventory of the risks identified in each work unit of the company or establishment”.
In order to carry out an inventory you must:
1. Identify potential danger or sources of risk
2. Analyse risks by observing exposure conditions
3. Apply the method on all work units
KIMEA will help you to save time on this inventory section on the issue of musculoskeletal disorders. Indeed, with KIMEA you will be able to film all your work units in a simple and non-invasive way, possibly several operators on the same unit, and then analyse the risks with the software in a fast and reliable way. You will also be able to compare the risks of your different unites and thus prioritize actions, establish appropriate budgets.
