Dental Surgery Management

Should be a dental nurse had to clean feces lurking?
I work in a dental office as a dental assistant and have been encouraged by management to clean the shed in the yard, the shed is full of feces and urine of mice. I refused to do this work because it is in my job description. Do I have the right to reject and what are the rules about this? I'm sure I've been trained to deal with rodants and I am sure I have the right to refuse?
Sorry, this dental office to work to make sure that I can not. This is not something that a nurse working with patients should do. This is a job for a maintenance person, an exterminator, etc. are not even "trained" to work with these hazardous substances (Yes, Animal feces can be considered a hazardous substance.) Did you even offered for you to wear protective gear such as gloves, a species of ventilator, respirator aparatus, etc? I refuse to do so. No pun intended, but it is BS that they are required to do so.
