The Air We Breathe in Industrial Environments. This industrial safety film explains the hazards of breathing air contaminated by various industrial pollutants, and the importance of wearing proper safety gear when doing various kinds of industrial jobs. It’s pretty standard for the most part, but there’s an old guy who’s not the narrator who has a great set of visual aids in the form of blocks that represent various concentrations of gasses, including one that says “FATAL” on the bottom (a must for the Film Ephemera Museum of Quriky Devices). Also, there’s lots of footage of gritty-looking industrial environments, where it’s hard to breathe just looking at them. Take a deep breath, folks, and be grateful you don't work in a coal mine. Ratings: Camp/Humor Value: ***. Weirdness: ***. Historical Interest: ****. Overall Rating: ****.
