CONTROL T he Army reinvigorated its efforts to control and prevent corrosion in its equipment just over two years ago. High operational tempos, environmental conditions, and inadequate shipment preparations have resulted in huge losses due to corrosion. Corrosion control and prevention reduces equipment loss, major repairs and downtime, and increases the power and effectiveness of deployed forces. Losses due to corrosion are largely due to lapses in preventive maintenance that could have found and treated corrosion before major damage occurred. The key factor that will truly control and prevent corrosion is the singular Soldier or DA civilian who operates or maintains Army equipment. This issue of PS Magazine is dedicated to renewing our efforts to improve readiness and decrease the costs of corrosion. I ask you to join with me in this task. Wimpy D.

Water your flowers and they’ll grow. Wash an engine in its container and it will groW RUSTy! W hether you’re deploying or redeploying, the elements of corrosion will make your containers cages of corruption if you give them room. Containers are meant to protect your equipment wherever you’re shipping it. Here’s what you can do to control corrosion during those long-distance treks: • Don’t power spray equipment while it’s in its shipping container! Moisture that is trapped in a container designed to keep it out will make a rust heap out of your equipment. • Shipping container gaskets need PM, too! If they are broken, corroded or just worn out, they can’t do their job. Replace or repair them. Inspect them every time you inspect the container or its contents. • Check the humidity sensors on the containers! Is humidity controlled or running amok? • Learn what corrosion looks like! Check out Pages 27-34 in this book. Find corrosion, remove it, coat and lube the equipment per the TM and ix the container or get a new one. Corrosion is your business. if you discover it, take charge and correct it. Prevention is a military, monetary and moral duty!
