With the rapid creation and development of new materials, made possible by advancements in material science, questions have arisen regarding whether specific substances used to deliver improved fire protection need to be balanced against any potential impact to the environment or society’s increased focus on personal health effects. As early as the mid-2000s, governments worldwide simultaneously commenced a systematic review of numerous chemicals to determine what threat, if any, they may pose either to the natural environment or to human health. This is an important debate that encompasses a broad range of issues and merits close scrutiny to carefully weigh the consequences of such a complex risk/benefit analysis.
In one such case, hexabromocyclododecane (HBCD), the flame retardant used in polystyrene rigid foam insulation, has undergone a formal chemical review process to identify potential risks associated with its production and use in a variety of applications, including foam insulation, computer housing components and in textiles.
