挪威：消防安全

“法律”是指具有约束力的规则。“官方指南”并非法律，但检查人员会参考它。“Chef Hygiene 默认值”是指在没有规则给出具体数值的情况下，应用程序会检查的值。

• 官方指南Fire extinguishers: an owner look every 3 months, a certified control every year, and a service every 5 years (water, foam) or 10 years (powder, CO2), as in standard NS 3910 named by DSB. The law asks for checks by risk (FOR-2015-12-17-1710, § 5).
• 官方指南Gas: DSB’s table gives a check of large-kitchen gas equipment and pipe tightness every 2 years. From 1 January 2027 the law adds a condition check at least every 5 years and a gas detector.
• 法律Electrics: the law asks for necessary inspection and maintenance (FEL, § 9) and sets no fixed interval.
• Chef Hygiene 默认值Hood and duct: Chef Hygiene checks against the insurers’ rule (FG-1100:1): fat filters at least weekly, duct and fan every year, and an automatic fire suppression system serviced every 6 months. This is not law.
