1. Overall strength: This helmet can withstand the collision energy and the penetrating impact of the steel cone specified in the standards 5.8 and 5.9 of the GA294-2001 "Police Riot Helmet" of the Ministry of Public Security. For impacts that exceed this energy, it can only give you the highest intensity of protection and reduce the damage caused to you. Therefore, when the helmet has experienced a major collision accident, it should be stopped immediately or sent to the factory for appraisal to confirm whether it can continue to be used.
2. Overall appearance: Do not smear the helmet body or use corrosive solvents to remove oil stains, so as not to damage the strength of the helmet body material.
3. The use period of anti-riot helmets is three years.
