[Risk communication for protection against hazardous substances in the workplace]. / Risikokommunikation zum Schutz vor Gefahrstoffen am Arbeitsplatz.

Hazardous substances are ubiquitous in the world of work. Employees from all sectors are exposed to different risks when working with hazardous substances. This also applies to people who do not directly handle hazardous substances (bystanders). Risk communication in occupational safety and health takes place at different levels. The spectrum ranges from large to small companies, safety experts, company physicians, works and staff council representatives to employees and the general public. Risk communication in occupational safety and health along the supply chain aims to create risk awareness among manufacturers, employers and employees to reduce risky behaviour and to encourage risk-reducing behaviour.Instruments of risk communication are explained in this article and considered with regard to their effectiveness. This affects binding instruments in the European internal market such as the hazard label or the safety data sheet (SDS). At the level of the Hazardous Substances Ordinance, they are the Technical Rules for Hazardous Substances (TRGS), limit values, the Easy-to-use Workplace Control Scheme for Hazardous Substances (EMKG) and, as a creative instrument, objects of the "DASA Working World Exhibition" in Dortmund, Germany. The results of the paper show that an adaptation of the instruments is necessary, especially for small and micro-enterprises, in order to find the appropriate entry point into risk assessment. Often, the existing instruments are not known, too extensive or difficult to understand. Recommendations for action are necessary that make it easy to get started with risk assessment. Existing scientific studies tend to focus on the deficits in risk assessment rather than on the development of efficient ways to communicate risks. Further analyses of the needs of the different target groups are necessary for appropriate risk communication.

Assessing the protection of the nanomaterial workforce.

Responsible development of any technology, including nanotechnology, requires protecting workers, the first people to be exposed to the products of the technology. In the case of nanotechnology, this is difficult to achieve because in spite of early evidence raising health and safety concerns, there are uncertainties about hazards and risks. The global response to these concerns has been the issuance by authoritative agencies of precautionary guidance to strictly control exposures to engineered nanomaterials (ENMs). This commentary summarizes discussions at the "Symposium on the Health Protection of Nanomaterial Workers" held in Rome (25 and 26 February 2015). There scientists and practitioners from 11 countries took stock of what is known about hazards and risks resulting from exposure to ENMs, confirmed that uncertainties still exist, and deliberated on what it would take to conduct a global assessment of how well workers are being protected from potentially harmful exposures.
