Q: We are based in Colorado. Do our red bins for biohazard waste need to be locked in a closet or if it is OK to keep them behind a closed door that is not necessarily locked?
A: There is no specific OSHA regulation that requires medical waste to be locked in a closet, and in looking at the Colorado state public health regulations, it appears that there is no specific requirement to keep medical waste in a locked closet on that count either. If there is a relationship with a local hospital, it may be worth checking with them to see if there is a specific requirement (if there is one anywhere, it would be in the state regulations as there are none at the national/federal level), but it looks like a closed door will suffice.
Now, I will complicate things just a little bit by saying that if you have clinic settings that provide care and services to at risk populations like pediatric and/or behavioral health patients, then you might be better off locking the closet to ensure their safety. It’s definitely a judgment call, but there are certainly instances in which erring on the side of caution is more than appropriate.
