About

I'm posting historic films and film clips from the rich history of workplace and environmental health and safety that can be helpful in understanding today's issues. These are primarily from government and industrial films created before 2000 and most are in the public domain. The films and clips discussed here are an excellent resources for teachers and for health and safety trainers. The films and clips can be very useful as triggers for discussions and to liven up training, especially the many refresher training required these days. For each film and clip, there is information on the original source, how the clip continues to be relevant and links to additional sources of information. Contact me at for more information. I hope you find my channel interesting and useful.
