Aug 03, 2017We spent the day at Quarry Bank which was an industrial textile mill that used orphan children from ages 7 up to 20 as basically slave labor to work in the mill. Working 12 hours a day, inhaling cotton dust, and possibly getting fingers severed in the noisy machines, was hell on earth. Housing conditions were horrible.

Quarry Dust Control Facts: FACT #1. The use of heavy-duty trucks and excavation equipment in quarries causes more dust than other vehicles, so dust control spray is more helpful than ever. FACT #2. The lungs of quarry and mining workers can struggle to filter out small dust particles making the air near a quarry particularly hard to breathe.
