I apprenticed with the Carpenters' Union just after the establishment of OSHA, in 1971. Most of my work was off the ground, forming large concrete structures and building scaffolding for other crafts to work safely off the ground. That first year OSHA implemented regs requiring us to be tied off to safety lines at all times when we were more than thirty feet off the ground. We resisted because it felt like complying slowed us down too much. My attitude changed when I returned to work eighteen months after shattering my right leg in a twenty-five foot fall. While I had learned patience, it was clear that safety came at the cost of productivity.

I think your overall conclusion is correct, but it is worth analogizing the struggles in construction safety with the struggles in construction automation, because they come from the same source.

It is easier to identify and mitigate safety issues in manufacturing processes for the same reason that it's possible to automate them: we have near-absolute control over the built environment in which they take place. We can add safety features to machinery, including shielding rotary assemblies and driveshafts from human contact, providing climate control, incorporating hand shields and reducing access around sharp objects, etc. We can train workers on processes that will be the same, day in and day out, down to the literal motion of their limbs around a piece of machinery.

These things often do mildly impact productivity relative to the baseline of no safety features or training (sewing machines are an emblematic case), but because they're often introduced simultaneously to other machinery and process improvements and because they reduce disruption, downtime, and turnover, they are only a small drag on productivity.

Moreover, safety equipment, by its nature, is most cumbersome when being moved, installed, or uninstalled. Thus it mainly impacts maintenance in factories, not production. But safety equipment on construction sites is *always* being moved and reinstalled as part of routine operations, so the impact is worse because the nature of site work makes safety measures more routinely invasive.

In addition, because we already struggle to implement any kind of productivity-enhancing automation, safety improvements are arriving on their own, unaccompanied by the sort of broader process and equipment improvements which would mask their impact. When industrial sewing machines began introducing needle guards, for example, they were simultaneously pioneering reversible functions and computer-aided stitching, so the slight slowdown that most experienced seamstresses will admit to seeing with a needle guard was hidden in the wash.

Fall protection for steel erectors, meanwhile, came alone, with no such productivity advances to mitigate it.

Overall I agree that safety practices are a drag on productivity rather than the main determining factor, but they are more challenging for the construction sector for the same reason that automation is more challenging.
