Summary: |
As part of an initiative to ensure that nanomaterials are safely developed, this report investigates methods of detecting airborne carbon nanotubes. Very fine multi-wall carbon nanotubes (MWCNT) are used in the manufacture of carbon nanotube electrodes and yarns. Investigators measured potential nanoparticle release in a carbon nanotube yarn production facility, but were unable to determine if any loose airborne nanotubes were released. Concentrations of nanotubes below one fiber per milliliter of air may be difficult to measure. To determine the efficacy of detection methods, carbon nanotube aerosol was also intentionally created by nebulizing nanotube dispersions. Electrostatic Low-Pressure Impactors (ELPI) were successful at detecting airborne nanotubes at concentrations of 20 fibers per milliliter. Further research is needed on whether airborne nanotubes are emitted during manufacturing processes and on improving detection methods to a concentration of one fiber per milliliter. |

An Evaluation of MSDS and Labels Associated With the Use of Engineered Nanomaterials |

Summary: |
This report contains an evaluation of fifty Material Safety Data Sheets (MSDS) and fifteen labels for products containing engineered nanomaterials. It is intended to consider how information on MSDS and labels reflects the current knowledge level concerning hazards, risks, and controls of nanotechnology. Companies were contacted directly for the MSDS and labels, in addition to obtaining them through internet searches and existing literature. The evaluation checklist examined whether the information obtained was reliable, relevant to nanomaterials, and accurate. Only 18% of MSDS provided a sufficiently accurate description to permit an occupational risk assessment. For carbon nanotubes, eleven out of twelve MSDS defined the hazards to be those of ordinary graphite. This is contrary to current scientific knowledge that nanotubes pose a greater health risk than large-sized carbon. Recommended handling and protection procedures also varied greatly across products. Overall, the report concludes that MSDS and labels must improve the quality and reliability of information. |

Engineered Nanomaterials: Evidence on the Effectiveness of Workplace Controls to Prevent Exposure |

Summary: |
This literature review has brought together and evaluated evidence on the effectiveness of workplace controls to prevent or minimize exposure to engineered nanomaterials. Only workplace settings such as laboratories, pilot plants and production plants have been considered; environmental safety and consumer product safety were not considered. The review has determined that there is evidence that control and risk management methodologies which are already known can provide levels of protection for workers from exposure to engineered nanomaterials in the occupational environment. Further testing and data is needed in specific workplace situations to understand the levels of protection afforded, and ensure effectiveness. With that said, there is a lack of health effects data currently available for many engineered nanomaterials which therefore necessitates a precautionary approach to the prevention and control of workplace exposures should be used. However, once data about the health and safety risks have been determined and defined, the principle of ‘As Low As Reasonably Practicable’ (ALARP) can be adopted. |

Summary: |
This review reports the current understanding of the toxicology and health hazards associated with engineered nanomaterials, and the implications in regard to health hazards in occupational settings (i.e. during manufacture, handling, and use). It updates a previous review by the Australian Safety and Compensation Council. The information in this review is based on scientific literature published from 2006 to 2008, however, during the editorial phase some important publications from the first half of 2009 have been incorporated. |
