Thanks for a well-paced presentation on this tool. I get the sense that I could have gone without studying the manual with a presentation like this when I first encountered this tool many years back!

Good presentation, practical, useful and well paced. Set at just the right technical level for general users. Thank you.

Thanks for the informative video. I've been watching your jiujitsu videos for over 10 years. How crazy that we are interested in this field too!

Awesome video, so much great information.

Question: If I'm in an IDLH environment, what kind of escapes are best for a white belt?

Great video… love your BJJ videos too:)

Where did you get those equivalence values? I have read 1% lel equals 10.000 ppm but 1% O2 equal 50.000 ppm? I woud like to read more about it. Also your h2s values dont seem to be correct according to NIOSH but i will check again. Thanks for your talk it was really informational and simple

Where did you get the cross sensitivity chart?
