The fire retardant sweater, professionally known as the firefighter's flame retardant sweater or fire-resistant thermal underwear, is an important part of the firefighter's personal protective equipment system. It is not an ordinary sweater, but a professional base layer clothing made of permanent flame retardant fibers, specially designed for firefighters operating in cold environments. Its main function is to provide the necessary warmth while ensuring extremely high safety and preventing the clothing from burning or melting in high temperature environments, which can cause secondary injuries.

"Armored vehicle" refers to a military or police vehicle fitted with protective armor, capable of resisting small arms fire, shell fragments, or improvised explosive devices (IEDs). According to the purpose, protection level and firepower configuration, it can be divided into many types Core features include: Protective: The body is covered with metal/composite armor to protect against bullets, fragments, explosive shock, or chemical corrosion. Mobility: Adapts to complex terrain (off-road/urban), with some amphibious or airlift capabilities. Mission adaptation: Configure weapons, sensors, or special equipment (e.g. mine clearance devices) according to requirements. Crew protection: airtight three-proof system (anti-nuclear/biological/chemical), fire extinguishing and explosion suppression device, shock-absorbing seat. Application field: Military: battlefield assault, force projection, fire support. Police/Security: Counter-terrorism, VIP escort, crowd control. Civil: cash trucks, high-risk area survey vehicles.
Firefighting rubber boots, more commonly known professionally as firefighter rubber boots, are a type of firefighting boot made from an all-rubber material, designed to provide firefighters with basic but vital protection during firefighting and rescue operations. Compared to more modern leather/composite construction firefighting boots, it is known for its excellent water resistance, chemical resistance and cost-effectiveness.
A riot suit (also termed anti-riot armor suit or tactical riot gear) is specialized protective equipment designed for law enforcement personnel (e.g., police, SWAT teams) to counter violent confrontations, terrorist threats, and crowd control scenarios. It provides integrated defense against stabbing, blunt-force strikes (e.g., batons), chemical splashes, and high-impact projectiles through modular components covering 11 critical body zones, including the torso, limbs, and head. Key features include: Lightweight construction (approx. 8-13 kg total weight) using flame-retardant synthetic fabrics (e.g., oxford cloth, engineering plastics); Rapid deployment (<7 minutes for full assembly); Compliance with GA 420-2021 standards for stab/impact resistance and environmental adaptability (-20°C to 55°C)
Fire helmets are comprehensive personal protective equipment worn by firefighters during firefighting and rescue missions to protect the head from a variety of injuries such as falling objects, flame burning, high temperature heat radiation, electric shock, lateral extrusion, and liquid chemical splashing. It is one of the most visible and critical components of firefighter personal protective equipment (PPE) and is known as "the firefighter's second life".
Firefighting suits, known as Structural Firefighting Gear or Turnout Gear, are full-body personal protective suits worn by firefighters during firefighting and rescue missions. They are the most important life support system for firefighters in the face of extreme hazards such as high-temperature flames, high-temperature heat radiation, chemicals, and sharp object collisions, rather than ordinary work clothes. The core definition includes the following elements:
A bulletproof helmet is a single soldier's head protective equipment, mainly used to resist damage to the head from projectiles or fragments. Its core function is to protect the wearer from fatal injuries in the battlefield or high-risk environments. The structure usually consists of a helmet shell, suspension cushioning system and face mask, and is made of advanced materials such as polyethylene, titanium alloy and Kevlar fiber to improve protection while reducing weight; models such as Browning bulletproof helmets also integrate neck protective cape components to optimize wearing comfort and defensive range
