New functionalities – daily average concentration

This year we continued developing Stoffenmanager®. Within the risk assessment the duration of the task needs to be selected. The duration was divided in several ranges. From now on the duration of the task can be entered in minutes. The duration of the task is used to calculate both the task concentration and a daily average concentration per risk assessment. You can then directly see if the exposure during the task and averaged over a full working day is sufficiently controlled.

The figure shows how many scenarios are sufficiently controlled. This is indicated by the risk characterization ratio (RCR). The RCR is calculated by dividing the concentration with the limit value of the component. A RCR ≥ 1 indicates that the exposure possibly exceeds the limit value. This is indicated in red. In column one the concentration during the task is directly compared with the limit value. This indicates whether or not exposure during the task is sufficiently controlled. The duration of the task is taken into account in column two. The column indicates whether or not the exposure during the full workday is sufficiently controlled. If a worker performs multiple tasks with the same component on the same day the total exposure (or job title exposure) can be calculated. Column three indicates whether or not job scenarios are sufficiently controlled. The last column show which REACH scenarios are sufficiently controlled.



Article implementation workplace Stoffenmanager®

A few years ago 45 companies were actively accompanied in working with Stoffenmanager®. Using the Stoffenmanager® Implementation ladder companies stepwise learned to safely work with hazardous chemicals. Companies were stimulated in setting steps on the Stoffenmanager® Implementation ladder, aiming to get to the highest level, in order to anker their substances management in the organization. Most companies succeeded to improve one or two steps. 76% succeeded in improving at least one step and 62% of the companies succeeded in improving at least two steps ahead or even more.

Factors of success- and failure were made visible. Amongst other things the main conclusions are that training and coaching provide added value when working succesful with Stoffenmanager®. Your hazardous chemicals policy improves a lot and considerably less mistakes are being made. A conclusion also being made by the international E-team study. You were able to read about this in a previous newsletter. Finally the results of the project have now been published in an article that can be downloaded here.


Succesful start with Stoffenmanager® Premium in Finland  

On January 1, 2016 Stoffenmanager®Premium was launched in Finland.

In order to help users to make a successful start with Stoffenmanager® Premium, we have organised a number of webinars, trainings and information days. The webinars were held in English and Finnish, by experts’ from Cosanta (owner and developer of Stoffenmanager®) and The Finnish Institute of Occupational Health (FIOH).

The first training "Working with Stoffenmanager® Premium” for the Finnish Premium users took place on February 9, 2016 in Helsinki (English) and on February 11, 2016 in Tampere (Finnish). An experienced Stoffenmanager consultant from Cosanta, and trained experts from FIOH provided the training. The participants have learned about Stoffenmanager® scientific background, risk assessment, transferring data from SDS, establishing workplace scenarios, scoring model parameters and the correct interpretation of the results. Users also explored the premium functionalities and received tips how to make use of them.

Cosanta, in collaboration with FIOH, will continue supporting the current and the new Finnish users to get a better understanding of the Stoffenmanager® model and to make a successful start with the Premium package.

Finnish companies interested in Stoffenmanager® Premium, training or other support in establishing their effective hazardous substances policy can approach us via the website or by sending an e-mail to

Exposure assessment and Risk management of hazardous materials in the workplace

EU manufacturers and formulators are being driven by two requirements when handling hazardous materials. The first is the need to ensure worker safety from the Chemical Agents Directive (CAD), which is implemented in the UK as the Control of Substances Hazardous to Health (COSHH) Regulations; the second is exposure assessment to demonstrate compliance under REACH.

Hosted by REACHReady, this free webinar will be presented by Prof. Geoff Le Grys (Prefusion LLP) and Dr. Henri Heussen (Cosanta BV). It is aimed at Health & Safety Practitioners and Operations Managers from EU chemical and pharmaceutical companies. It will also interest Health & Safety Consultants. Prefusion LLP is a REACHReady Approved Service Provider. Participant numbers are limited so contact us today to reserve your place!

The Chemicals Industries association (CIA) has posted the details of the webinar on their website.  It can be seen here.  We intend to follow up with a campaign to send this to our contacts and post it on our website

When? March 1, 10.00-11.30 CET


You can meet us at…..
