This training provides employees information on protecting themselves from nanoparticle titanium dioxide exposure. It defines nanoparticles as less than 100 nanometers and notes titanium dioxide is commonly used but also produced as nanoparticles, which studies show can cause greater health risks than larger particles. The training objectives are to define nanoparticles and titanium dioxide, discuss health hazards from exposure, and explain proper protective equipment to reduce risk. It will include a presentation, discussion of protective gear, and a quiz to evaluate learning.

Course Title How to Protect Yourself against Nanoparticle-Titanium Dioxide Lesson Title Small Particles, Large Problems- Nanoparticle-Titanium Dioxide Course Background A nanoparticle is any material that has at least one dimension that is less than 100 nanometers. They exhibit unique properties because of their small size and large comparative surface area. National Institute for Occupational Safety and Health (NIOSH) has studied in great detail the toxicity of incidental exposures to nanoparticles generated from processes involving combustion, welding, or diesel engines. However, less is known about nanoparticles that are intentionally produced (engineered) with diameters smaller than 100 nanometers and uncertainties exist as to whether they pose occupational health risks. These uncertainties arise because of gaps in knowledge about potential routes of exposure, movement of nanomaterials once they enter the body, and the interaction of the materials with the body’s biological systems. Results from existing studies in animals and humans on exposure to incidental nanoscale and other respirable particles provide preliminary information on the possible adverse health effects from exposures to similar engineered nanomaterials. However, the potential for nanomaterials to pose health or safety hazards is greater if the nanomaterials are easily dispersed (such as in powders, sprays, or droplets) or are not isolated or contained. Titanium dioxide (TiO2), an insoluble white powder, is used extensively in many commercial products, including paint, cosmetics, plastics, paper, and food, as an anticaking or whitening agent. It is produced and used in the workplace in varying particle-size fractions, including fine and ultrafine sizes. Production in the United States was an estimated 1.45 million metric tons per year in 2007 [DOI 2008]. Recently, the use of nanoscale TiO2 has increased above average and it is currently the most widely used nanomaterial to date. NIOSH has determined that nanoscale TiO2 particles have higher mass-based potency than larger particles, and that occupational exposure (by inhalation) to nanoscale TiO2 particles should be considered a potential occupational carcinogen. Previous studies found that, even though there is
no significant evidence of TiO2 exposure and lung cancer mortality, workers exposed to TiO2 had particle retention of titanium, silica and other minerals even sometimes years after cessation of exposure (NIOSH 2011). Rats and mice studies have shown that TiO2 can cause pulmonary inflammation and cell damage at sufficiently high surface area doses. Regulations Occupational Safety and Health Administration: In workplaces where workers will be exposed to nanomaterials, the employer should provide information and training to their workers. Training should include identification of nanomaterials the employer uses and the processes in which they are used; The use and limitations of PPE; Emergency measures to take in the event of a nanomaterial spill or release. OSHA permissible exposure level for TiO2 is 15 mg/m^3. OSHA recommends that worker exposure to nanoscale particles of TiO2 not exceed 0.3(mg/m3). Training Target Group Employees exposed to Titanium Dioxide in packaging processes. Lesson Objective Give employees a better awareness of titanium dioxide at the workplace and how they can reduce their exposure to this nanoparticle. Learning Outcomes By the end of the workshop: • employees should be able to define what are nanoparticles and titanium dioxide • employees should be able to list the health hazards associated with titanium dioxide exposure • employees should be able to recall the proper PPE to reduce exposures to titanium dioxide
