I DON'T KNOW.

IT'S SCARY.

I HEAR WOLVES!

IT'S BEEN SO LONG.

GUYS, GUYS! WE CAN DO THIS!

IN THIS PACKAGING SERIES, WE'VE BEEN TALKING ABOUT A "MAZE OF CONFUSION" THAT'S CAUSED BY A FAILURE TO UNDERSTAND THE DIFFERENT KINDS OF MILITARY PACKAGING PRESERVATION METHODS.

WE'VE ALREADY COVERED METHODS 10 AND 20. THIS MONTH WE'LL DISCUSS THE THIRD PACKAGING PRESERVATION OPTION, METHOD 30.

THIS METHOD IS A BIT TRICKIER THAN THE FIRST TWO, SO YOU'LL NEED A TRUSTY MAP TO 'EXIT THE MAZE" OF PACKAGING PRESERVATION OPTIONS USING METHOD 30.

THE BEST GUIDE TO USE IS MIL-STD-2073-1, STANDARD PRACTICE FOR MILITARY PACKAGING.

METHOD 30 PRESERVATION REQUIRES USING WATERPROOF OR WATERPROOF-GREASE-PROOF PROTECTION (WITH PRESERVATIVE, AS REQUIRED).

PACKS ARE APPROPRIATE ALMOST ANYTIME THE ITEM WILL FIT INTO A BAG, A RIGID CONTAINER OTHER THAN ALL METAL, OR AS LONG AS ONLY WATERPROOF OR WATERPROOF-GREASE-PROOF PROTECTION IS NEEDED.

HOWEVER, METHOD 30 ISN'T THE RIGHT CHOICE FOR PACKAGING IF WATER-VAPORPROOF PROTECTION IS ALSO REQUIRED-IN THAT CASE, YOU MUST CHOOSE METHOD 40 OR 50.

TO USE METHOD 30, PLACE AN ITEM THAT IS PRESERVED, WRAPPED AND CUSHIONED AS NEEDED INTO A CLOSE-FITTING BOX OR CARTON.

ENCLOSE THAT BOX, IN TURN, IN A SEALED WATERPROOF BAG.

* Clean and dry the item.

* Select and apply a preservative coating to the item or parts of it.

* Apply a greaseproof wrap conforming to MIL-PRF-121, Type I or ii.

* Select a close-fitting inner container from MIL-STD-2073-1 or the container specified by the contract or order. See Page 53 of Container Selection.

* Insert the item into the container along with cushioning and dunnage. This will protect the item from any projections or sharp edges and restrict its movement within the container.

* Blunt the sharp edges and corners of the box to protect the bag selected in Step 7.

* Enclose the box in a bag conforming to MIL-DTL-117, Type I, Class B. The following are examples of barrier (bag) materials meeting the MIL-DTL-117 requirement: A-A-3174, Type I or II, Grade A, Class 1 (see note below) and MIL-PRF-22191, Type III. Note: When specified, a protective wrap of heavy-duty kraft paper or equivalent (tape sealed) should be used to protect the barrier material.

* Heat-seal the bag. Keep the trapped air between the box and the bag to a minimum by compressing the bag or by using mechanical means, such as a vacuum cleaner attachment. Be careful not to rupture the bag.

* Apply markings according to MIL-STD-129.
