Had great time kicking off #NAAMC in Pittsburgh with a personal tour of NIOSH lab where they do a ton of work on mine safety and respiratory dust protection. This apparatus is designed to create a clean air curtain around workers in high Quartz-content dust generation activities.

This is a $50K dust vacuum closet designed to remove dust from workers clothes to avoid clothing-derived dust exposure post-shift.

This is a full scale mock up of this insane typewriter-like machine that shaves away the mining walls while also holding the ceiling up to prevent it from collapsing.

This is a room built to emulate/show how little room there is to maneuver around this massive digger machine that is worming its way through the center of the earth.

Two of the most sophisticated dust sampling chambers in the world where MOD-PM will be put to the test in the coming month to see how well it can measure these particles. TEOMs and APS running as ref kit.

Live action shot of MODULAIR-PM doing some routine facility monitoring.

A super fascinating tour and eye opening experience for me. Hard to grasp the sheer scale and complexity of the work that NIOSH does to keep workers safe. Thanks to Emanuele Cauda for the invite! Look forward to returning for some epic dust chamber exps in the Fall.

old school

Also pretty neat to be at the facility where my Aura was actually certified. 😷
