Ammunitions Storage Room at a Sherriff's Facility

well as normal with mythbusters

they used the small caliber bullets, yea right, surprised they did not throw a A-10 20 mm bullet in there!!!!!!!!!!!
 
The video shows a 50 caliber shell casing and lead slug from the fire. this casing is what caused the most damage to the wooden "target" teepee. In essence, it really is a matter of phyics, a bullet when heated in a fire will send the casing as a projectile becasue the mass of the lead bullet is heavier than the brass casing.....
 
Very true BB and they also make the same whizzing sound as if the mass of a solid piece of lead was projected.....you'll have to trust me on that one since I would not want anyone else to experience what me an another firefighter experienced one hot day in a mobile trailer on fire :o
 
The term “explosive” includes any material determined to be within the scope of USC Title 18: Chapter 40

From USC Title 18, Chapter 40: the term “explosive” means gunpowders, powders used for blasting, all forms of high explosives, blasting materials, fuzes (other than electric circuit breakers), detonators, and other detonating agents, smokeless powders, other explosive or incendiary devices within the meaning of paragraph (5) of section 232 of this title, and any chemical compounds, mechanical mixture, or device that contains any oxidizing and combustible units, or other ingredients, in such proportions, quantities, or packing that ignition by fire, by friction, by concussion, by percussion, or by detonation of the compound, mixture, or device or any part thereof may cause an explosion.

They are also generally classified as explosives by the MSDS, generally Division 1.4.

That is how I know FF PPE will stop the pieces without to much hurt on the wearer--it was a duck and cover moment.

Cans of hairspray scare me more as they land with fireball.
 
planchecklgb,

Welcome to The Building Codes Forum! :)

Did you get your answer from this discussion?

Builder Bob, ..definitely too much info & visualizations for the viewing audience. :D

.
 
Thank you Globe Trekker,

We did find our answer, or at least know what we're calling the occupancy of this room : H3, Explosives Class Division 1.4

Thanks for all the "interesting" responses. We were entertained and informed !
 
h-3 ??? how did you get there??

Is the building sprinkled?? and going to meet all other h-3 requirements???
 
2009 IBC / 2010 CBC : 307.2 Definitions:

*************************************************************************************

UN/DOTn Class 1 explosives. The former classification system used by DOTn included the terms "high" and "low" explosives as defined herein. The following terms further define explosives under the current system applied by DOTn for all explosive materials defined as hazard Class 1 materials. Compatibility group letters are used in concert with the division to specify further limitations on each division noted (i.e., the letter G identifies the material as a pyrotechnic substance or article containing a pyrotechnic substance and similar materials).

Division 1.4. Explosives that pose a minor explosion hazard. The explosive effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire must not cause virtually instantaneous explosion of almost the entire contents of the package.

***********************************************************************************************

Table 307.1(1) limits 100 lbs (50lb in table, but increase for approved storage cabinets per footnote e) for Division 1.4 explosives per control area. When this limit is exceeded, it's an H-3. The architect has noted these amounts will be exceeded.

Building is fully sprinklered. A 1 hour separation from other rooms will be required.
 
So a Walmart it cabelas or your favorite sporting goods place if built would have to have a "H" component??? In it
 
Would you also consider a parking deck an H use group due to the aggrigate amount of explosives in the cars and trucks?

Airbag inflators and seat belt tensioners are a class 1.3 explosive.

One pound makes for an H-2 use.

The fire code restrictions are for unassembled ammunition bulk powder and bulk primers.

Once assembled ammunition is non hazardous.

Where can I find this in the IBC or IFC or NFPA regarding assemble ammunition as non-hazardous. This means that a retail store or warehouse can sell boxes of ammunition with a B or M occupancy....not an H occupancy...is this correct? Please provide reference.
 
You bring up
" assemble ammunition as non-hazardous"

Do you want to manufacture in the same building, or is this a misprint and want to store only??
