If you were to walk onto a construction site 40 years ago, you might have seen workers going about their tasks in hardhats, steel-toed boots, safety glasses, and hearing protection. The buy-in may be better today, but considering you can walk on a construction site today and see more or less the same safety gear, how much has really changed? Plenty. But the innovation is in the minute details. Each weld, joint, grommet, stitch, hinge, and even the molecular structure of modern PPE is rigorously tested and standardized.
