If crime-scene cleanup was just wiping blood off the floors—well, that would be easy. But CSI fans with get-rich-quick dreams should note the job involves more than handiness with a mop and a tolerance for the smell of decomposing flesh. Getting rid of bodily fluids typically calls for more rough-and-ready methods, such as ripping up carpet, tile, and baseboards. It also sometimes means working in confined spaces (if someone was electrocuted in an attic, for example). And when tearing up old houses, workers face exposure to hazards such as lead paint and asbestos—not to mention the combustible chemicals involved in drug-lab abatement.
