I didn't mean space suits LITERALLY, but YES they do have to wear a protective suit when the raid these places becuase of the highly combustible chemicals that are involved in making meth. And yes, there have been horrible, horrible accidents that meth makers have endured due to the lack of protective gear when in the process on making meth.
Can you imagine taking a drug that is cut w/ Draino and bleach and whatever else synthetic chemicals that shit's made of... imagine going days without sleeping how unnatural and fucked up that is. It is PATHETIC that the govermment is taking the time to crack down on MJ users rather than meth users. Don't expect a stoner to try speed, it's meth that's the killer.
