Because smoke coming from an intense fire is under pressure, it is forced deep into cracks and crevices, into and through porous materials. Smoke particles have an odor that haunts building owners long after clean-up, particularly when humidity is high. FIRE D will finish the job by removing the odor. Use FIRE D ONE SHOT AEROSOL FOGGER to kill after-fire odors in automobiles and other small enclosed areas where a fogging machine would be awkward or electrical power is not available. Use one can for every 10,000 cubic feet of space.
