In episode four of a five-part series, Mike and Bob continue discussing APIE and how it applies to hazmat.

Complete Show Notes

6:05 Container Material Release Continued

  • Detonation
    • This is simply a violent and rapid ignition of a product that corresponds with the disintegration of the container
  • Violent rupture
    • This is where the products release relatively quickly – timeframe is around one second
    • Size of container doesn’t affect the speed of the rupture
    • Engulfment/dispersion – refers to how far it’s going to go and how it’s going to react in terms of release
    • This is how the product gets into the environment and spreads, especially when dealing with gasses

8:45 Release of Gasses

  • If a gas really wants to expand in volume, it’s referred to as a cloud
  • Plumes are cloud aquatic products with shape and buoyancy
  • Cones have linear and radial dispersion that expands as it moves away from the point of release
  • Whether the hazardous material is released as clouds, plumes, or cones, it’s going to impinge on something and cause damage and disruption – this can be life or property

12:55 APIE and How Hazards Affect Us

  • APIE helps us break down how hazardous materials impinge on objects – can be short-, medium-, or long-term
  • If we take the information we’ve already gathered and minimize the hazard’s effects, we’ve done a great service to the community
  • Knowing and understanding how a hazard affects an area changes our tactics and how we treat people
  • Mishandling hazards can ultimately affect infrastructure, like roadways, transportation hubs, and electrical grids
  • Hazards can lead to injuries, illnesses, and death – injuries affect us in the short term, while illnesses can impact us in the long term

16:00 Choosing PPE and TRACEM

  • It’s very simple – choose your PPE based upon how much the hazard can harm you
  • Damage and harm comes from TRACEM factors
    • T – thermal (i.e. hot and cold, endothermic vs. exothermic)
    • R – radiation
    • A – asphyxiation (i.e. simple and chemical)
    • C – chemical (i.e. hydrofluoric acid)
    • E – etiological/biological (i.e. diseases)
    • M – mechanical (i.e. detonations or bullets)
