The lifespan of riot control equipment varies depending on its type and materials. Different equipment has significantly different design lifespans, typically ranging from 3 to 10 years, with some high-intensity use equipment potentially having a shorter lifespan. Below are some reference lifespans for common riot control equipment:
Riot Control Firearms
Type 97-1/Type 97-2 18.4mm Riot Control Rifle: Designed lifespan ≥3000 rounds. It can serve for many years under normal usage, but requires periodic mechanical performance checks.
Type 91B Rifle-mounted Grenade Launcher: Lifespan exceeds 2000 rounds, effective range approximately 300 meters.
Protective Equipment
WJY99-4 Bulletproof Vest: Designed lifespan 10 years, capable of withstanding Type 79 submachine gun steel-core bullets.
Stab-proof Vest: Generally has a lifespan of about 5 years. Replace immediately if the inner liner is damaged or deformed.
Riot Shield:
Composite Material: 3–5 years (depending on usage frequency)
Metal Material: 5–8 years (requires regular rust prevention)
Transparent Window: 2–3 years (prone to aging, regular replacement recommended)
Police Equipment and Auxiliary Gear:
Riot Baton (e.g., Model 2002): No specific lifespan, but avoid exposure to heat, direct sunlight, and corrosive substances. Damage to the rubber surface will affect its lifespan.
Tear Gas Sprayer: Generally effective for 3 years. After expiration, the spray pressure and irritant effect will decrease.
High-Intensity Flashlight: Bulb life can reach 100,000 hours, and the battery can be recharged 1000 times, but attention should be paid to sealing and circuit aging.
Other Explosion-Proof Equipment Reference
Explosion-proof motors/cameras: The design life is typically 5–10 years, greatly affected by ambient temperature, humidity, and load intensity.
Chemical protective clothing: The shelf life is 2 years for basic models and 3 years for Class 1 protective clothing, depending on the specific usage.
