As the petroleum laboratory specialists and the inspector from the 1st Sustainment Command (Theater) walk into the lab -- a mobile trailer called the Petroleum Quality Analysis System-Enhanced -- they smile at the smell of fuel as if they just entered a coffee shop. The lab holds all the equipment needed to perform quality surveillance testing of bulk fuel allowing petroleum laboratory specialists, or PLSs, to begin testing samples within 120 minutes of arrival to a deployed environment. The inside of the lab is well lit, ventilated, clean and organized to allow the PLSs to reach most fuel testing tools within arm's length.
