We highly recommend using OSHwiki (http://oshwiki.eu/) as a source of health and safety knowledge. It is relatively new platform to share professional know-how and ideas, developed in form of an online encyclopaedia hosted by European Agency for Safety and Health at Work.
As we can read in the promotional leaflet, “OSHwiki is a web platform based on the user-generated ‘Wikipedia’ style concept. It provides an ideal way to share specialised knowledge and collaborate online within the health and safety at work community. OSHwiki articles can be written by accredited OSH professionals and scientific organisations, but everyone can access OSHwiki to reference the large variety of informative articles.”
