Occupational Exposure Level(OEL) validation

Dear All,
I am working in a formulation company manufacturing Hormone and Oncology products.
We are going to perform Occupational Exposure Level(OEL) validation

Please guide me regarding Occupational Exposure Level(OEL) validation.

Regards
Kumar

Different hormonal and antineoplastic products have different levels of limits depending on the harm they cause or activity based on their absorption thru the mucous, nasal and skin.

Unless you gives us compounds no one can really tell you a tighter limits.
