Bomb Squads 101 Information for Writers

EXCERPT FROM MISSING LYNX - Book Two

We watched the monitor closely; the robot stood flush with the case. A pincer reached out to twirl the locking system, using the combination that I had uncovered while behind the Veil. The mechanical arm moved with amazing dexterity, slowly releasing the catch, retrieving the papers and files. Axel wiggled the toggle and the robot zipped back to us with the booty. Again Axel maneuvered the machine to the case. The robot sent a video image to our laptop; I studied the screen until I could show Axel where the concealed latch protected the hidden compartment. We all held our breath while Axel maneuvered the motorized claw to release the hook.

The following information was gathered from bomb squad members that I met at this year's Writers' Police Academy. Because of their undercover work, neither their names nor images can be used in this article. A bomb squad member is also called an EOD (Explosive Ordinance Disposal) Technician. All EOD Techs come through the Redstone Arsenal in Huntsville, Alabama where they undergo an intensive 6 week training session.
* There are at least two people per responding team.
* Typically this team prefers nine members
* On this team, the EOD techs have other police duties and leave those duties to respond to bomb threats.


The Suit

Bomb Protective Suit is a little bit of a misnomer. Though it can help; it will not actually keep someone alive under all circumstances. What makes a difference in survivability?
* How close is the officer?
* How big is the blast? The concussion of the blast can be as deadly as the shrapnel.
* At five feet from the bomb survivability increases by 50%

I am all suited up at the Writers' Police Academy 2013

I'd explain this to you, but then I'd...  EOD Suit WPA 2013

THE SUIT

  blast concussion.
* Cost? aprox 75k
* The suit weighs approximately 85-100 lbs.
   35 lbs for the trousers
   35 lbs. for the jacket
   8 lbs. for the helmet
   And boots.
   This suits allows little in the way of dexterity and
    agility. More armor might increase protection 
    but make movement impossible.
   (Though this guy is going to prove me wrong: VIDEO QUICK STUDY - dancing in a EOD suit 2:17)
   * The helmet includes a fan unit to help prevent  humidity from building up inside of the visor. But
      does not cool the person inside.
   * The suit has no cooling unit - considering the  weight of the suit, the body response to adrenaline and 
       physical activity, and the ambient temperature a bomb technician has about a twenty minute window
       of operational opportunity. 
   * If there is a possibility of a contaminant or bio-hazard, the team members have access to special suits
      that incorporate oxygen tanks (SCBA Self-contained Breathing Apparatus). These tanks add to the
      weight and loss of agility. These usually have about 45 minutes of air. That time period must include time 
      to "decon" (decontaminate).

TOOLS-
VIDEO QUICK STUDY - Tools in use (3:53)
1. Telescopic manipulator - has a claw allowing a technician to work from a safer distance.
2. Ordinance disposal tools - the one we saw was approx. 35 lbs and could shoot the bomb. Also, there
    are:
   * robots with hooks, arms, car door openers, etc.
   * water jet disruptors

   * laser aiming devices, and so forth.
3. Remote viewing systems that might include
  * Borescopes
  * Videoscopes
  * Fiberscopes
  * X-ray technology 
4. Disruptors - can open up the package.
5. Bomb Detection Dogs
    VIDEO QUICK STUDY (2:32) 
   * Dogs are typically taught to sit or lie down when
      they detect the scent.
   * Typically they are rewarded with a ball
   * Dogs are trained to the base component of
      explosives. Once they have these components
      any combination will trigger an alert. Dogs smell
      differently than humans if a human smells "stew," a
       dog  smells carrots, and beef and onion, etc.
WPA 2013 That's my scary  backpack.
 I named the robot  "Molly," because she needed a name.
6. Robots
   * Cost? Approx 125K and up
   * Depending on model, these are around 44 lbs.
   * VIDEO QUICK STUDY (3:41) 
     THIS IS EXCELLENT
   * Major issue is depth perception. That's
      why these techs practice, practice,
      practice.
   * Information is transmitted via wireless to
      the  HAZMAT truck

ASSESS, ASSESS, ASSESS
Video Quick Study British EOD Tech talking about the "Long Walk" and assessment  (2:38)
For a bomb to go off there need to be three components:
1. Battery
2. Switch
3. High Explosive Charge
Disrupt any of these and you render the bomb inoperable.

Basic Techniques

(Techniques are kept secret so as not to train the attacker in better ways to succeed)
VIDEO QUICK STUDY - Suspicious Package Investigation (9:02)
1. Determine that there is a possible event. In the case of the technicians I was interviewing, most of their
    calls come from people who have found dynamite, or war souvenirs (WWII from granddad) and not
    from actual concerns about a bomb.

2. Bring in the team and their trucks
   * Mobile Headquarters with gear also called
      HAZMAT Truck
   * Containment Truck
   * EMTs and fire
3. Clear the area to ensure the public's safety
   * Set up equipment this might include tenting if
      they believe bio-hazardous materials were
      used.
4. Suit up
5. Develop intelligence
   * They cannot use radio communication because it could set off the bomb.
6. Formulate a plan
7. Work the plan and leave.
   * If they are exploding something they yell, "FIRE IN THE HOLE!" three times.
   * Exploding the object is called "disrupting the device."
   * Counter Charge - means to put another explosive device on top of the suspected bomb and blow it up
