These are videos developed by Kansas State University to address the problems with explosions in agricultural facilities and other grain/vegetable dust processing facilities.
The physics and chemistry of a grain dust explosion
Hazards of grain and other organic dusts
Control measures for prevention of catastrophic dust explosions
Target Student Population:
Various populations could be targeted.
Prerequisite Knowledge or Skills:
Type of Material:
DVD also available in VHS
Good for basic class in fire or safety on dust explosions.
Player mechanism and or the ability to load on a streaming video server for a "closed" audience. Use for a larger audience may have copyright issues that will need to be worked out with KSU
Evaluation and Observation
Very professionally produced with good documented case studies and factual background.
Potential Effectiveness as a Teaching Tool
The overall DVD is very effective in showing potential problems, safety measures, and consequences of dust explosions. Narration is strong but stresses the learning objectives.
May seem melodramatic
Ease of Use for Both Students and Faculty
Need equipment or own streaming server. limits the breadth of use based on the resources available. However the purchase price ($25) is nominal.
Other Issues and Comments:
K-State may want to consider a talking paper to go along with the DVD. This would give the instructor a chance to stop the DVD and discuss various portions rather than sitting and watching for 30 minutes then try to go back and review.
