What is the correct process for removing tear gas residual?

The process of removing tear gas residual involves using HEPA vacuuming, which is specifically designed to capture fine particles, including chemical residues. Tear gas leaves behind very small particles that can be harmful if inhaled or touched. HEPA vacuums have filters that can trap these microscopic particles, ensuring that they do not become airborne during cleanup.

In contrast, standard vacuuming might not have the necessary filtration system to adequately capture these fine residues, allowing potentially harmful materials to remain and become a health risk. Dry cleaning techniques may be ineffective for tear gas residues, which require a more thorough approach, as they are designed for fabrics rather than the potential chemical residues left on various surfaces. Wet wiping can help in the cleaning process but does not address airborne particles effectively, and without the proper filtration, it may not remove all residues effectively. Therefore, HEPA vacuuming is the most reliable method for ensuring thorough removal of tear gas residuals.
