I think it would be cool if you could sanitize a room or a corpse using a kit of some kind with the forensics skill. Uses would be:
- Reduce the risk of infection from medical procedures
- Reduce the risk of equipment failure/destruction when using equipment that requires certain room types
- Clean up crime scenes or bodies to prevent forensics from being used effectively on them.
In the case of using it on rooms, I'd think the reduction in bad outcome would be proportional to the skill in forensics and last for a limited duration, maybe a day or something.
