Riot control agents like CS gas (tear gas) and OC spray (pepper spray) are not only harmful to humans but also corrosive to equipment. The chemicals can degrade metals, cloud transparent visors, and deteriorate fabrics and plastics. To counter this, riot gear undergoes specific protective treatments. Metals used on helmets, shields, and harnesses are either made from stainless steel or are coated with corrosion-resistant finishes like powder coating or anodizing. Polycarbonate visors and shield windows are treated with chemical-resistant hard coatings that prevent the agents from etching or hazing the surface. Fabrics used in suits and carriers are often made from synthetic fibers like Nomex or polyester that are inherently resistant to chemical degradation, and they may be treated with a durable water repellent (DWR) that also helps shed liquid chemicals. This ensures that the equipment remains functional and reliable even after repeated exposure to harsh chemical agents.
Core Knowledge:
Corrosive Agents: CS gas and OC spray can corrode metals, cloud plastics, and degrade some fabrics over time, compromising equipment integrity.
Protected Metals: The use of stainless steel, anodized aluminum, or powder-coated finishes protects metal components from rust and corrosion.
Chemical-Resistant Coatings: Transparent plastics like polycarbonate are given special coatings to resist etching and hazing caused by chemical agents.
Synthetic Fabrics: Inherently chemical-resistant materials like Nomex are used for suits, and DWR treatments help bead up and shed liquid chemicals for easy decontamination.
