Inhalation: Limestone dust: May cause respiratory tract irritation. Adverse symptoms may include respiratory tract irritation and coughing. Prolonged or repeated inhalation of respirable crystalline silica liberated from this product can cause silicosis, a fibrosis (scarring) of the lungs, and may cause cancer.

Silica (SiO 2, CAS No. 7631-86-9) is found in abundance in nature. Pure crystalline silica that is not combined with any other elements is called free silica. When combined with other elements, the compound is called silicate. Free silica occurs in different polymorphic forms like quartz, cristobalite, tridymite, and tripoli.

For one tone of crushed limestone, you would pay around $25 to $35. 1.5 tons are enough for one cubic yard. The cost per yard can start at $30 and go up to $45. For example, the price for one yard is around $40 at Mains Landscape Supply. For the bag of 50 pounds, you can pay anywhere from $5 to $10. If you need large quantities of limestone

breathing dangerous levels of Silica are referring to Crystalline Silica, not Amorphous Silica. While the Federal NIOSH airborne limit for the very dangerous Crystalline Silica is only 0.05mg/m3, the IDLH on Amorphous Silica is a whopping 3000mg/m3, which is 60,000 times higher than Crystalline Silica.

According to the National Cancer Institute, crystalline silica is an abundant natural material found in stone, soil, and sand as well as concrete, brick, and mortar. Crystalline silica from quarry is “respirable,” meaning people can breath it in. When inhaled, according to the NCI, the particles can penetrate deep into a person’s lungs.
