“A portable decontamination sprayer designed for toxic environments. The device features a backpack-style tank in olive green metal with yellow hazard stripes and reinforced hoses leading to a heavy-duty spray nozzle. Pressure gauges, control valves, and warning labels are mounted on the top of the tank. The surface shows scratches, chemical residue marks, and industrial wear. The object is perfectly centered against a pure white background, softly illuminated with neutral studio light, minimal shadow. Ultra-realistic 8K PBR materials with painted metal, rubber hoses, and subtle surface grime.”
