Background: Engineered nanomaterials (ENMs) may pose health risks to workers. Objectives were to characterize ENM applications in construction, identify exposure scenarios, and evaluate the quality of safety data sheets (SDSs) for nano-enabled construction products.
Methods: SDSs and product data were obtained from a public database of nano-enabled construction products.
The study assessed potential to exceed occupational exposure limits while spraying paint with and without a silver nanoparticle biocidal additive. A tradesperson performed the tasks in a sealed chamber with filtered air supply. Integrated air sampling entailed transmission electron microscopy with energy dispersive X-ray analysis, direct-reading of particle number concentrations, and determination of silver mass concentration by NIOSH Method 7300.

A tradesperson performed the work activities in an environmentally controlled chamber. Samples were collected in the tradesperson's breathing zone and in surrounding areas to assess bystander exposure.

There are concerns about the safety of manufactured nanomaterials, and exposure assessments are needed for a more complete understanding of risk. This study assessed potential inhalation exposure to ZnO nanoparticles during spray application and power sanding of a commercially available wood sealant and evaluated the effectiveness of local exhaust ventilation in reducing exposure.

- - A conference called "Worker Training in a New Era: Responding to New Threats" was held in 2002 to assess health and safety training needs for workers facing potential threats from weapons of mass destruction, like chemical and nuclear weapons (CBRNE).
- - The event aimed to identify common skills all workers need when exposed to CBRNE threats, as well as specific skills needed for different sectors, resulting in thirteen core components for pre- and post-event training.
- - Key recommendations included establishing clear competencies for training, improving coordination on federal training policies, and developing new training methods to enhance worker safety in the face of CBRNE threats.
