I don’t see where the government has any right to stop a person from putting themselves in danger of getting killed especially if you tell them that saving you is none of their business!
All my life i’ve taken chances of getting hurt or killed if the odds were in my favor and I wasn’t endangering anyone else and it saved time.
Most cases it was something that would be illegal if I told an employee to do it but OSHA couldn’t touch me.
I don’t think you are under any obligation to allow fire department personnel on your property unless the fire is endangering other property. I could be wrong.
