No Parapet

We have a job to do on a building that watches us like a hawk. I know we are operating safely, but there is about a 50’ section of the roof with no parapet. Does anyone know what OSHA expects from us in this situation?
Thanks

That’s a great question. Following…

I should mention that i am using a rooftop roller

The building has eyes?

Wouldn’t it be the same as any other job, make sure you are attached when every you approch an edge?

Pictures?
