Season 04 Episode 04: "It's time to put the lid on dust," Trajce advances. Engineered stone, silica exposure - this has been in the media of late. The trio, Alan, Trajce, and Sara, discuss who is vulnerable to these exposures and why. Trajce argues that the regulators must not demonise one hazard exposure. Rather, pragmatism is needed to determine the safety of work.

Alan argues the case that even when a business adheres to the workplace adivsory exposure standards for respirable dust, it does not matter when evaluated by a regulator. Trajce reminds us that dust is everywhere across many industries.

Sara begs the question, "Are you an intentional designer or an accidental designer?" She argues that there is a cost to making decisions that impact on workers and systems when the trade-offs are not considered. Sara stipulates that just because a person makes work-related decisions, it does not make them strategic or intentional. Many times, work design is accidental.

Sara pays tribute to a friend and mentor, Ms Peg Pinard of San Luis Obispo County, California. In her ode to Peg, she reflects on the concerns about engineered stones and the smoking ordinances instituted and pioneered by this Californian City and the County.
