It's an interesting challenge to match the core message of a video with the level of detail that it includes. I agree that the overall question of appropriate lab ventilation could be the subject of a similar video, but in the context of this project, the details of the components of overall management system are beyond the scope of our intent.

>I do take a little issue with describing risk as essentially a measure of probability alone.

I agree that the words "most likely" unintentionally emphasize probability in the risk function. Would "most likely to present a significant risk" bring in the concept of severity adequately?
