Assuming there are no violations of OHSA or other relevant regulations, the employer may do this: the employer may change job duties and have janitors, instead of nurses, take on this responsibility. But the employer must obey OHSA regulations about such materials, and you are encouraged to contact OHSA and find out what the regulations are about this specific situation. You should also call the state agency licensing nursing homes and see if they have any regulations covering the subject. And call your municipal and/or county board or department of health, which may have its own regulations for disposal of such materials. One or all of these agencies may be able to help you.If the employer is not barred by any regulations from doing this, then they can, as stated, make it your responsibility. They do not need to offer you any additional pay for doing this--the employer decides how much to pay you for doing your job, and what your job consists of. If you are harmed in any way by a lack of training, safety or protective equipment, etc. you should be able to sue for your injuries, medical costs, lost wages, etc.
