Recent updates

Large-scale testing of a foamed rock dust applied wet and allowed to dry was conducted at the Central Mining Institute in Poland in 2019. Due to COVID-19 related issues, a final report of results has been delayed, but will be completed in the coming months.

Due to COVID-19 related concerns, site access to laboratories has been severely limited and efforts to establish the dust dispersion chamber as a NIOSH standard method are on hold. Testing will resume once regular access is permitted.
