Respirators are essential personal protective equipment (PPE) on sites with airborne contaminants because they protect the wearer's respiratory system. These contaminants, such as mold spores, dust, asbestos fibers, or chemical fumes, can cause serious health issues if inhaled. Respirators filter out harmful particles or gases, ensuring clean air for breathing and safeguarding worker health.

Drywall is highly vulnerable to water damage because it is made of gypsum plaster pressed between sheets of paper. When exposed to water, drywall quickly absorbs moisture, leading to swelling, softening, crumbling, and rapid mold growth. Unlike steel, ceramic tile, or concrete, it loses its structural integrity and becomes a breeding ground for contaminants.

Soot is best removed from non-porous surfaces using specialized techniques like HEPA vacuuming to capture loose particles without spreading them, followed by chemical sponges (dry cleaning sponges). These sponges are designed to absorb and lift soot residues without smearing them, which is crucial for effective cleaning and preventing further damage to the surface.
