The answer is yes if they are accessible to employees. What does accessible mean? It means no passwords--no logins can exist that would be a barrier to information.
For those of us who remember a time when employers stored SDS’s or MSDS’s as they were called years ago in a binder and that binder often hung on a wall in a work area, it was accessible. Now, imagine if that binder was stored in a box on the wall with a lock on the box and employees didn’t have the key, those MSDS’s would not have been accessible. Same is true of electronic or online access, there cannot be barrier to this critical information which is most often needed in times of crisis where someone needs to access the information immediately.
I hoped this helped clarify one aspect of Hazard Communication Compliance.
