If a owner hires a contractor? But he doesn't tell him the danger that he is about to get into is he liable?

Question

A company hired me I didn't know about the penta that was in the pipes and cyclinder. And it made me very sick. Is he liable.

Answer 1

the company is the responsible party for not reseaching first.

Answer 2

There is some expectation that the contractor is a professional and will check for hazards themselves, also that they carry their own insurance.
If you did not check and don't carry insurance, I would very politely, inform the owner of the toxic issue and see if they are willing to cover your medical, but they may not be because you are not an employee, you are a contractor.
