Firefighter slang for a police officer at a fire or accident involving hazardous materials. Usualy it's because cops will approach the scene without any breathing apparatus or protective gear. When you see the cop keel over, call the mop and glow squad and get the hell out!
Oh shit! We got an officer down by the overturned truck carrying Benzene. Call Chemtrec!
