What precautions should I take to ensure my employees are safe when working with garnet abrasives?

As an employer, you are responsible for assessing the risks that your employees may be exposed to under normal and non-routine/emergency conditions.  It is recommended that industrial hygiene-exposure assessments be conducted periodically when working with garnet abrasives to define the appropriate safe work instructions.  The results of these hygiene exposure assessments should be evaluated against published personal exposure levels (PELs) to determine the appropriate personal protective equipment and engineering controls, and to document regulatory compliance.
