Some airborne contaminants are lead, epistasis, silica, hex crome, chemical vapors, etc. OSHA has access to multi employee citations. This means if you are on the job site and it wasn't you who created the contaminate, but you were on the jobsite you can still get cited for the hazard.
We have so many classes and checklists to ensure that you and your employees are protected from airborne contaminates. Learn more about our risk management department here - https://ibcins.biz/risk-management/
