Step-by-step explanation:
The protective gear described, worn in environments with sparks and molten metal splashes, with elastic sides or quick-release buckles for swift removal, corresponds to aprons. Aprons are essential personal protective equipment (PPE) designed to shield the wearer's body from specific workplace hazards. In environments like welding or metalworking, where sparks and molten metal are prevalent, aprons provide a crucial barrier, and features like elastic sides or quick-release buckles enhance safety by allowing rapid removal in case of an emergency. This ensures that workers can efficiently protect themselves while maintaining the flexibility needed for their tasks.
