Alex,

You state your laboratory is in your Radiology Department.  The healthcare environment is highly regulated a fact which previous commentators have not mentioned. Joint Commission on the Accreditation of Hospitals (JCAHO), CDC/NIH, state and local health departments have infection control regulations for patient treatment areas as well as areas directly contiguous to patient treatment areas.  They also have emergency and fire code requirements. You might wish to find out what classification the laboratory in your radiology department has relative to this. 

You do not state what chemicals are used in the radiology lab.  A 2020 article published in Appl Occup Environ Hyg. 2002 Feb; 15(2):203-8, doi:10.1080/1047322003011700 https:​//pubmed.ncbi.nlm/.nih.gov/10675978/ states that "A variety of chemicals are used in medical imaging as developers and fixer ingredients, germicides and cleaning agents. Glutaraldehyde, a potent sensitizer, may cause occupational skin and respiratory diseases in exposed individuals. Poor ventilation, unsafe practices, and lack of hazard recognition may contribute to occupational asthma and other respiratory disease in susceptible medical imaging personnel."  

For laboratories in general the CDC/NIH Biosafety Manual  is not only a guide but often times written into organizational procedures.  Specific discussion regarding floor surfaces can be found in the CDC/NIH, Biosafety in  Microbiological and Biomedical Laboratories (BMBL), 6^th Edition,  June 2020, Section D, Laboratory Facility, p. 48-49, "Floors are slip-resistant, impervious to liquids, and resistant to chemicals. Flooring is seamless, sealed, or poured with integral cove...Seams, floors, walls, and ceiling surfaces are sealed. Spaces around doors and ventilation openings are capable of being sealed to facilitate space decontamination...".  If your radiology department lab receives NIH grant money following the CDC/NIH BMBL is a requirement. The CDC/NIH guide is usually for labs handling etiological agents (e.g., hospital clinical labs such as Microbiology/Virology or research labs) . However, are contaminated potentially infectious equipment (e.g., endoscopes) brought to this lab for decontamination in germicides such as glutaraldehyde where a spill could contaminate a floor surface with carpet? 

I am sure your University of Washington hospital (clinic?) is accredited.  Look at JCAHO infection control, fire safety and emergency management requirements. Many JCHO fire regulations are covered by NFPA 99 - National Fire Protection Association (NFPA) Healthcare Facilities Code.  They are binding.  A violation will potentially lead to a lower JCAH rating which can result in loss of accreditation with lower reimbursement rates or potential closure of part of a facility or the entire facility.  If you are referring to an outpatient facility the three major accrediting bodies are: The AAAHC (Accreditation Association for Ambulatory Health Care), the AAAASF (American Association for Accreditation of Ambulatory Surgery Facilities), and JCAHO (Joint Commission on Accreditation of Healthcare Organizations).   

All hospitals have a Hospital Safety Committee and Infection Control Committee.  Additionally, a large university affiliated hospital (which may include ambulatory treatment facilities, independent clinics, etc. as part of a medical center) may have other safety committees (e.g., Laboratory Safety, Biosafety, etc.).  Depending upon activities being performed in the Radiology Lab you have many potential advocates.
