Firefighter gear, also known as personal protective equipment (PPE), is designed to protect firefighters from heat, flames, and hazardous materials. Key components include a helmet, which shields the head from falling debris, and a fire-resistant jacket and pants made from materials like Nomex or Kevlar. These garments help prevent burns and provide insulation against extreme temperatures. Additionally, firefighters wear gloves and boots that are also heat-resistant and provide grip. A self-contained breathing apparatus (SCBA) is crucial for supplying clean air in smoke-filled environments. Together, this gear ensures that firefighters can perform their duties safely and effectively during emergencies.
