I accidentally sprang a chemo line when going to the toilet during treatment (in day oncology) - truly not my fault, the cannula was faulty. But much running in gowns and gloves and wellie boots, as you don't want this stuff on you. In you is a different matter! Same thing with toilets. Lid down and flush twice. If you are having three weekly chemo, problem abates a bit after the first 4/5 days. To be honest, I have never heard of anyone having a bad outcome so I think the scare tactic works a treat!
