Make employees and customers aware of the theft problem. Store tanks in a well-lit or high traffic area. Store tanks with flow valves facing toward the drive lane to speed visual inspections. Do not leave tanks in fields or remote areas. Inspect tanks visually first thing each morning.
Many thefts occur over the weekend.
Remove hoses and store them separately. There is enough ammonia ina standard decoupling hose to make meth. Block the driveway with a gate or barricade. Place brightly colored plastic ties or wire seals between the valve wheel and the roll cage to ease visual checks. Record stored nurse tanks by identification number and weight of remaining product.
