Results of Interesting and Unusual NIOSH Health Hazard Evaluations (AIHce EXP 2020 OnDemand)

Course Description:
Recorded at Virtual AIHce EXP 2020

The NIOSH Health Hazard Evaluation Program is a public health practice program that responds to requests about potential hazards in the workplace from across the United States. This roundtable will present the results of three unique and interesting evaluations involving new or emerging hazards in novel settings: 1) We evaluated exposures to asbestos during a prescribed burn near a former vermiculite mine. Asbestos fibers were detected during multiple tasks performed throughout the burn. The majority of fibers were found during dry activities and during tasks associated with plant and soil disturbance. We made numerous recommendations to help decrease fiber exposures.; 2) We evaluated park ranger exposures to radon and radon decay products at a tourist cave and a connected building. Radon concentrations inside the cavern were below regulatory limits, but employees have the potential to exceed whole body ionizing radiation dose limits due to the unique aspects of the cave environment. We made numerous ventilation and administrative control recommendations do reduce employee exposure.; and 3) Additive manufacturing, or 3D printing, is increasingly being used in nonindustrial areas like K–12 schools and universities. This rapidly evolving printing process has resulted in work practices, employee exposures, and engineering controls that have not been fully evaluated. We will discuss results and recommendations from our recently completed surveys of 3D printing operations at these nonindustrial worksites.

Learning Objectives:
Upon completion, the participant will be able to:

  • Discuss how the NIOSH Health Hazard Evaluation (HHE) process works.
  • Make an HHE request and understand who can make a request.
  • Describe the methodology used in HHE evaluations.
  • Make practical recommendations to control hazards.
  • Assess exposures related to wildland firefighter and asbestos, noise, metal hazards, and 3D printers.
