CCOHS has initiated a new online bulletin for the safety community in Canada called WorkScape (http://www.workscape.ca/).  There are some interesting threads on OH&S various safety topics.  I have subscribed to the threads relating to Safety Management Systems and will try to contribute to from time to time.  You can see all my Workscape posts here (enjoy!)

If you have any questions about general safety you may also want to check out their site and register.
