In this episode, we’re joined by Ash Boss-Handley, a Certified Occupational Hygienist with extensive experience across construction, tunnelling, and mining industries. Ash shares insights into the unique challenges of working in underground environments, where a range of hazards—some less visible than others—can pose significant risks.

While high-profile dangers often get the most attention, mould is a frequently overlooked issue in these settings, particularly due to inadequate ventilation and persistent humidity. Ash helps us unpack why mould deserves more focus, and how it impacts worker health and safety. We also explore what modern tunnelling and mining operations look like today, and the kinds of control measures used to manage these environmental hazards.
