In June 2007, a new set of regulatory requirements for the REACH substances came into force (Regulation (EC) No. 1907/2006) (7). This is the most comprehensive set of chemical regulations to be enacted in the EU and the impact of these regulations will be global in nature. In the future, based on a specified set of deadlines all substances produced, sold, or imported in the EU will have to be registered. The regulations remove the distinction between new and existing substances and require the same level of comprehensive data to be submitted for all substances with the amount of information varying based on volume and inherent hazard.

For all substances produced above 10 tons annually, a chemical safety assessment will have to be submitted as part of the required information. For substances determined to be dangerous, a chemical safety report (CSR) must be developed and that CSR must describe exposure scenarios. Exposure scenarios are sets of conditions that describe how substances are manufactured and used during manufacture and ultimate use by the downstream users. The CSR must also have information on how the manufacturer or importer controls or recommends to control exposures to workers and the environment. The exposure scenarios must also include recommended risk management measures for all “identified uses.” These exposure scenarios and risk management measures will then need to be annexed in some way to MSDSs.

The REACH requirements further emphasize the need for industrial hygiene skills and practice to be involved in these chemical control regulations. Exposure evaluation, specifically for downstream uses of chemical substances requires exposure evaluation skills. Overall the need to determine exposure through the life cycle of a substance and recommended control measures are an integral part of these precedent setting regulations.
