Protective aprons, smocks and cape sleeves protect workers from a variety of workplace hazards such as chemicals, flames, sharp objects and particulates. Protective aprons cover a worker's torso and thighs, while cape sleeves cover the arms, shoulders and chest. Both are used in welding applications to protect workers from sparks, moderate molten splash and high heat. They also protect workers who must handle sharp or abrasive objects and materials. Smocks are used in laboratories to protect against liquid splash and dry particulates. Cleanroom smocks prevent ESD (electrostatic discharge) buildup, while chemical-resistant smocks resist nonhazardous chemicals and pathogens.
