I. C. C. marking I. C. C. class

Description

Chemical ammunition filled with IM, PT or NP (thickened fuels) when assembled or packed with or w/o ignition elements, bursting charges or fuzes.

IM, PT or NP shipped in drums, barrels or other authorized shipping containers shall be classified as a flammable solid.

IM, PT or NP when shipped in authorized ICC specification containers or Chemical Corps specification containers of integrity equal to ICC containers (including bombs w/o ignition elements, bursting charges or fuzes) may be handled and stowed either as a flammable solid or as chemical ammunition Class II-G. Includes but is not limited to:

Bombs.

Bombs, cluster incendiary. Frangible grenades.

NOTE: The U. S. Army and Navy, when shipping ammunition filled with these incendiary compositions, mark such ammunition or containers thereof with the Chemical Corps symbol of the filler and one purple band.

Hazard

Stowage

Handling

The principal hazard of IM, PT or NP filled items is involvement in a fire. They burn rapidly with intense heat. Extinguishment of fires is best accom. plished by means of water fog.

Fog foam or a foam steam (mechanical or chemical) is likewise effective. CO, should not be used unless the fire is small and in its incipient stage. In holds of a vessel large volumes of water are recom. mended as a cooling agent provided such may be employed without "floating off" burning gel. The vapors from heated napalm are toxic and rescue breathing apparatus should be worn while working in noticeable concentrations.

Clusters of incendiary bombs in this category may contain a certain percentage of bombs having a high explosive charge capable of causing fragments which could be dangerous to fire-fighting personnel. Incendiaries of this type may contain ignition components of WP adding an additional hazard.

On contact with moisture, metallic sodium or lithium hydride will liberate large quantities of hydrogen gas thus producing an explosive hazard.

The reaction of metallic sodium with water is sufficiently violent to cause ignition of the liberated hydrogen. Fumes from burning sodium are caustic. On contact with moisture, calcium carbide or calcium phosphide will liberate phosphine and acetylene gases. The phosphine is toxic but extremely unstable, ignites spontaneously and at the same time ignites the acetylene gas.

Fires involving these items cannot be extinguished by water, carbon dioxide or foam.

Smothering with an inert substance such as dry sand or dry soda ash offers effective control. Jettisoning should not be accomplished in a port or roadstead as the floats will continue to burn until filler is consumed jeopardizing other vessels and piers.

Hazard

Stowage

Handling

The principal hazard of TH filled items is involvement in a fire. They burn rapidly with intense heat and usually form large quantities of molten iron. The presence of a small ex

plosive charge in some TH items forms an additional hazard in case of a fire. Carbon dioxide and carbon tetrachloride extinguishers should not be used to combat fires involving TH because the reaction of carbon tetrachloride with molten metal produces toxic gases and that of carbon dioxide on magnesium may produce an explosion.

In the hold of a vessel large volumes of water are recommended as an extinguishing agent. Fire fighters should work from behind barriers when pos. sible.

The amount of explosives in single items of this class varies from 30 to 500 grains. It is likely they will explode progressively. Structural damage caused

by the pressures generated would probably be limited to the immediate vicinity.

Missiles are light and usually fall within 300 feet. These types of ammunition are loaded with explosives that are sensitive to shock and friction. Shock and fire are the principal hazards to this type of ammunition. If involved in a fire, fire fighting personnel should take normal precautions and not expose themselves unnecessarily. Fire may be controlled and extinguished by flooding or spraying with large amounts of water.

1. Handle by hand or mechanical means. 2. Do not drop, drag, tumble, walk or otherwise subject packages to shock.

3. Do not use chute in loading or unloading. 4. Observe packages or containers for evidence of failure or inability to retain contents and reject any showing such signs.

5. Cargo handling stevedore gear may be trays, skipboards, pallets or pieplates provided_they are fitted with cargo nets or sideboards. Boxes or trays with fixed or removable sides are author. ized.

6. Cargo nets w/o trays, skipboards, pallets or pieplates are not permitted.

7. The maximum permitted weight per draft when handled by pallet, skipboard, tray or pieplate, fitted with cargo net or sideboards shall not exceed 4,000 lbs. plus 10%.

8. Drafts consisting of one or more palletized units shall not exceed 4,000 lbs. plus 10%.

9. Lifts of palletized units shall not be tiered except when using a sling so designed as to prevent the upper tier or tiers from shifting or falling from the draft.

10. Wire rope slings are permitted when handling unboxed bombs or containers filled with TH. (See table of Limiting Loads, Class X-A.) 11. The limiting weights noted above are for a 5-ton boom.. See § 146.29-41.

1. Handle by hand or mechanical means.

2. Do not drop, drag, tumble, walk or otherwise subject packages to shock.
