Silica (SiO2) is the second most common mineral in the earth’s crust and is a major component of sand, rock and mineral ores. Silica exists in several forms, of which crystalline silica is of most concern. Other types of silica include amorphous silica which is the major concern in Lash Miller (LM) Chemistry Laboratories.
The respirable silica protection program aims to protect the health and safety of lab personnel (researchers, staff and students) from silica exposure in the Lash Miller laboratories. It does so by assigning roles and responsibilities, providing guidance on best practices, the implementation of engineer controls, recommending change in common operations, conducting risk assessments, and implementing, if necessary, the use of fit-tested respirators with the associated training.
