A review of control banding and traditional industrial hygiene sampling methods for determining risk assessment of engineered nanomaterials in the workplace

The properties of engineered nanomaterials (ENM) are increasingly being developed and used for technological developments. At present there is a high level of uncertainty about the health risks associated with manufactured nanomaterials. The traditional industrial hygiene (IH) exposure assessment strategy for nanomaterials is highly tailorable to most situations and workplace environments and enables effective and efficient exposure management while control banding (CB) allows an appropriate level of risk control that could be established and can be reassessed according to developing scientific and technical knowledge of the products and processes involved. The article discusses the method for both types of assessments using previously published scientific literature.
