OHTA Hybrid International Day: ‘Connecting the Minds, Creating the Future’Silica Exposure – Artificial /Engineered Stone Countertops; How Big is the Problem?

Date: Thursday, Feb. 2, 2023 – Thursday, Feb. 2, 2023

Time: 5:00 p.m. – 7:30 p.m. (EST)

Location: Online

Event Type: Webinar

Join this Workplace Health Without Borders webinar on Silica Exposure.

For the last 10 years we have known about the risk of silicosis to workers who sand, grind, and cut engineered/artificial stone countertops. This material contains more than 90% respirable crystalline silica and includes organic compounds such as phthalic anhydride. Learn more about these risks around the world.
