- (a) Each canister or cartridge submitted for testing and approval in accordance with §§ [84.252](/cfr/42/84.252.md), [84.253](/cfr/42/84.253.md), and [84.254](/cfr/42/84.254.md) shall be equipped with a canister or cartridge end-of-service-life indicator which shows a satisfactory indicator change or other obvious warning before 1 ppm vinyl chloride penetration occurs.
