OSHA’s factsheet for working safely nanomaterials in the workplace suggests including the following basics in worker training and instruction:
• Identification of nanomaterials the employer uses and the processes in which they are used;
• Results from any exposure assessments conducted at the work site;
• Identification of engineering and administrative controls and personal protective equipment (PPE) to reduce exposure to nanomaterials;
• The use and limitations of PPE; and
• Emergency measures to take in the event of a nanomaterial spill or release.
OSHA also recommends using its on-site consultation services for employers attempting to address potential exposure to nanomaterials in the workplace and states that “On-site consultation services are separate from enforcement and do not result in penalties or citations.”
