It can’t get simpler than this! Ever so regularly my apartment block attendant comes to each floor to service the fire extinguishers and turn the canister around. Apparently they should be regularly shaken to prevent the powder inside from hardening. To make this important element obvious, the Turnover Extinguisher adopts the hourglass form, with the countdown timer, so that when the time’s up, you know instinctively to shake the extinguisher and keep it functional. No reminder needed!
