Protective pants protect workers from workplace hazards. They include high-visibility and reflective pants, scrubs and cleanroom pants, rain pants and heat- and fire-resistant pants. High-visibility and reflective pants make workers more visible at night and in busy or low-light conditions. They are typically colored bright orange or yellow and are lined with reflective stripes. Scrubs and cleanroom pants provide a strong barrier against particulates, pathogens and liquid splash, while rain pants seal out water and keep workers warm and dry. Heat- and fire-resistant pants protect workers from flames and high heat. They do not ignite or melt.
