Protective sweatshirt, coats and jackets protect against chemical splash, debris, fire, rain and cold temperatures. They include rain coats, welding and heat-resistant coats and chemical-resistant coats. Rain coats keep workers warm and dry, while welding and heat-resistant coats shield workers from sparks, flames and high heat. Chemical-resistant coats provide a barrier against chemical splash, pathogens and particulates. Protective coats and jackets often have reflective stripes that increase visibility in low-light conditions.
