I would turn to the official Occupational Safety and Health Administration (OSHA) website for latest information and newest OSHA regulation.
Basically, the administration main goal is to guarantee that representatives or workers are working in a protected and energizing climate by setting and upholding guidelines and also by giving preparation, effort, instruction and help.
This authoritative source which is its websites provides up-to-date information on regulations, guidelines and resources related to workplace safety including those specific to healthcare settings like dental offices.
Therefore, I would regularly visit the OSHA website to stay informed about any changes or updates in regulations that pertain to our dental practice.
