The National Institute for Occupational Safety and Health (NIOSH)
Its a very helpful website specially for HSE employee, because it will help them go understand National institute for occupational Safety and Health (NIOSH), information and programs such as, health care ,construction, oil and gas etration.
Also, it helps in understanding some topics about workplace safety and health like: hazards and chemicals,etc..
one of the great things about the website ,there are available NIOSH and un-NIOSH data and statistic resources in a variety of forms.
I prefer this website and i know its will help a lot in my department to prevent any safety error in future to improve the department

This link above will take you to a website that might help you with information that will assist you to train a safety employee .
Also, it helps to find safety books and safety events.
if you look for any safety data ,statistic and safety topics, you will not find these information over there . For that i will use this website in future for training purpose only.
