WARNING!  Viewer Discretion is STRONGLY ADVISED.  This is NOT the forklift video that has gone viral  which shows the lady being crushed after she attempted to be a counter weight.  This video shows us how speed and lack of seatbelt leads to tip-over fatality.

This is NOT an endorsement of any kind, but this video does an EXCELLENT job explain the difference between the three (3) most common types of "blinds" used in energy isolation.

This weeks video is all about "seeing is believing"!  The video is from a series of training videos made back in 1947 for the US War Department to training workers in the factories making war products.  These videos may be old, but they are timeless as the chemistry of flammable liquids and gases have NOT changed!   This video is one of my favorites as they use special back lighting to show us how the vapor of gasoline (heavier than air) behaves.

WARNING!  Viewer Discretion is advised.  This week's video shows a worker climbing a fixed ladder while holding onto blueprints (NO 3-point contact with ladder).  As he climbs he falls from the ladder to a platform.  The platform has a top rail, but does NOT have a mid-rail, allowing the worker to fall from the platform to the ground (~20').  We can see the worker land in a bad way and see his bodily response to the fall and yet co-workers run to his aid and sit him up as if he has no spinal injuries!

This week's video is a bit dated, but it is an EXCELLENT video for those who work around Anhydrous Ammonia (NH3).  It contains video showing just how hard it is to ignite NH3 outside, although there are flaws with their "testing methods".  And it also contains scenes that may be upsetting to some, as it has live news footage from the 1984 Shreveport, LA FD fatality involving the ignition of NH3 vapors.  Anhydrous Ammonia WILL BURN - it takes (depending on who's document you are reading) 150,000-160,000 ppm (15%-16%) to burn, but it WILL BURN. 

 

This week's video is one EVERY worker who transfers flammable and/or combustible liquids MUST see (note the best footage begins at the 2-minute part).  Of course the Battalion Chief is doing everything right (actually WRONG from a safety perspective) to get the gasoline vapors to ignite.  Here are a few things to consider when watching the video:

  1. notice that he does NOT let the dispensing nozzle come into contact with the container
  2. notice that he is splash filling into a 5-gallon container
  3. notice the container is sitting on a rubber mat (insulator), which is sitting on a cart that has rubber wheels (another insulator from ground)

So the static charge that is generated by flowing through the hose and then the charge that is generated from splash filing is CLEARLY enough to ignite the gasoline. By-the-way, gasoline has a Minimum Ignition Energy (MIE) of 0.8 mJ.  To put that into some perspective, we don't feel sparks until they are around 15.0 mJ.  Yes, that means that we will NEVER feel the static spark that ignites the gasoline vapors.  PROPER transfer of any flammable AND combustible liquid is a MUST each and every time - NO shortcuts!
