Hi
Faeces is a pathogen (carries disease) and you must be careful with splashes with a pressure washes, you can imagine it would be sprayed everywhere.
Spray the Faeces with a Biocide and leave for around 15 mins ( Microsan, Ornikil). Bag the faeces making sure you use gloves (rubber or latex) for faeces a light suit will do as if you have sprayed biocide all bacteria will have been killed anyway.
Urine is actually sterile (people actually drink it for their complexion

)
HIV doesn't live very long outside the host body. HIV is found in varying concentrations or amounts in blood, semen, girl thingyl fluid, breast milk, saliva, and tears and reduces between 90-99% within a few hours.
Your PPE will only have to be incinerated if it become saturated or contaminated, a chemical suit (non porous) can been cleaned with the biocide, rubber gloves can be cleaned, latex thrown.
Just be careful and count the cash

Regards
Martin
