Stoffenmanager, a Web-Based Control Banding Tool Using an Exposure Process Model

The Annals of Occupational Hygiene inform in Volume 52 about a new tool for
small- and medium-sized companies. In the scope of a Dutch programme to
reinforce the working conditions policy on hazardous substances, an
internet-based tool was developed to help small- and medium-sized companies to
handle hazardous substances with more care.

The heart of this tool, called the Stoffenmanager, is a risk banding scheme. It
combines a hazard banding scheme similar to that of COSHH Essentials and an
exposure banding scheme based on an exposure model originally presented by
Cherrie et al. (1996) and further developed by Cherrie and Schneider (1999).
The exposure model has been modified to allow non-expert users to understand
and use the model. Exposure scores are calculated based on categorization of
determinants of emission, transmission and immission. These exposure scores are
assigned to exposure bands. The comparison of exposure bands and hazard bands
leads to a risk band or priority band.

Following the evaluation of the priority of tasks done with products, generic
exposure control measures can be evaluated for their possibility to lower the
risks. Relevant control measures can be put into an action plan and into
workplace instruction cards. The tool has several other functionalities
regarding registration and storage of products. The exposure model in the
Stoffenmanager leads to exposure scores. These have been compared with measured
exposure levels. The exposure scores correlated well with measured exposure
levels. The development of the Stoffenmanager has facilitated a whole range of
further developments of useful tools for small- and medium-sized enterprises.
