I suppose, "Spread it on my lap so that I don't drip pineapple juice on my slacks when I eat the fruit" isn't the right answer.
Weaponized chlorine gas, in the field, smells like spicy pineapple. When you smell it and start to feel the effects, grab a large piece of cloth, saturate it with urine, and cover your head. Then retrieve your Lee-Enfield SMLE/303 and go about your business! Nothing simpler.
