Clean room equipment is kind of the opposite of what was needed. Clean room equipment protects the room from the people.

What’s was needed was likely pretty basic PPE: P100 respirators along with outer clothing that would be kept out of people’s homes and showers when leaving the site. (PAPRs would have been even better, but they wouldn’t have been cheap or available in large numbers on short notice.) Unfortunately, if you watch modern construction workers, you’ll find that PPE is almost universally ignored when performing common but dangerous tasks like cutting concrete or lead-painted surfaces.
