At the meeting, I was informed that crystalline silica, which is used in refractory materials, has been classified as a "carcinogenic substance" under the Industrial Safety and Health Act.
I think crystalline silica was classified as a Group 1 carcinogen in 1996, which means it is a definite human carcinogen. That was more than 20 years ago, why now? Super late.
On my way home from work, I took a break at Holly's Cafe.
