Crystalline silica becomes dangerous when it is Respirable.
Some are small enough to be worn clipped to clothing,
and are used to separate Respirable particles for later analysis.
Maritime and general industry employers now covered by Respirable crystalline silica standards should immediately
conduct a review of their written safety program(s).
PM2.5 is known as the Respirable suspended particulates which is harmful for human,
it will cause respiratory diseases and cardiovascular and cerebrovascular diseases very easily.
The best way to prevent silicosis is to identify work-place activities that produce Respirable crystalline silica dust
