WEBINAR - Controlling Occupational Exposures to Respirable Crystalline Silica

Content

Respirable crystalline silica is comprised of quartz (the most common form), cristobalite, and tridymite particles that have a 50% cut point of four microns in diameter (approximately 100 times smaller than beach sand); it is generated when cutting, sawing, grinding, drilling, and crushing stone, rock, concrete, brick, block, and mortar. Exposures may also occur during foundry work, hydraulic fracturing, road construction and repair, and during the manufacture of products such as glass, pottery, ceramics, brick, concrete, and artificial stone.

Employees exposed to excessive respirable crystalline silica concentrations are at increased risk of developing serious diseases such as silicosis, lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease. As such, OSHA has developed standards for the protection of employees in general, construction, and maritime industries who are exposed to respirable crystalline silica. This webinar will provide an overview of these OSHA standards, the performance of respirable crystalline exposure assessments, and the control of employee exposures to respirable crystalline silica.

Learning Objectives

After participating in this webinar, attendees will be able to:

  • Discuss respirable crystalline silica generation and its health hazards
  • Provide an overview of OSHA’s respirable crystalline silica standards
  • Discuss personal air sampling protocols to assess exposures to respirable crystalline silica
  • Identify and review general control measures that may be used to reduce occupational exposures to respirable crystalline silica
  • Identify industrial ventilation hood designs contained in the ACGIH® publication, Industrial Ventilation: A Manual of Recommended Practice for Design, 30th Edition, applicable to the control of exposures to respirable crystalline silica.

Who Should Attend this Webinar?

  • Occupational safety and health professionals
  • Management and employees associated with workplaces where exposures to respirable crystalline silica occur
  • Industrial hygienists

What is an ACGIH® Webinar?

ACGIH® is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning webinars. A webinar, short for Web-based seminar, is a presentation, lecture, or seminar that is transmitted over the Internet. A key feature of a webinar is its interactive elements — the ability to give, receive and discuss information. Webinars are as effective as on-site presentations without the travel expense. This ACGIH® webinar is 2 hours in duration and consists of a live presentation given via the Internet with an audio telephone link similar to that of a conference call.

Accreditation

This webinar contains 2 contact hours and may be eligible for Certified Industrial Hygienist (CIH) CM credit. See the ABIH website (abih.org) for CM credit criteria. This webinar may also qualify for CSP recertification points. See the BCSP website (bcsp.org) for details. Participants seeking confirmation of attendance for the webinar from ACGIH® must attend the live webinar or view the archive and submit a final exam and evaluation. Certificates of Completion will be issued in a timely manner after receipt and completion of these items.
