"It is safe to cut or grind hardened concrete that contains EdenCrete when wearing the required, normal, standard Work Safe Australia PPE (personal protective equipment).

As there is no Australian Standard (AS) or American Standard Test Method (ASTM) that measures the liberation of free CNTs from cutting or grinding hardened concrete, air monitoring was conducted during the cutting and grinding process to assess for free CNTs in the surrounding environment iii . In all industrial hygiene monitoring test cases, the EdenCrete Frangos CDM Smith 2020 report found that the concentration of free carbon in the air was less than 1 μg/m3 for 8-hour TWA of exposure, well below the recommended exposure level required by Work Safe Australia."

"If I spill Edencrete and it dries is it dangerous?

Even though EdenCrete will dry back to a powder, it will not revert to the original unincorporated nanotube state and is not hazardous."
