What precautions do we need to take?

I have a general question for all you oncology nurses out there. We have a resident (patient) in our LTC/SNF facility who is receiving radiation and chemo (temodar) for glioblastoma. It's been a very long time since I worked the oncology unit at my local hospital, but I recall there were sometimes special precautions we had to take. I understand the precautions to protect the resident, because of the potential for white cell destruction and higher risk of her getting an infection.But aren't there precautions we are supposed to take to also protect the staff?? Seems I recall something about some chemo drugs excreting in the patients urine? If someone would so kindly lead me in the general direction for information, I'd greatly appreciate it.
