Norway: fire safety

“Law” is a binding rule. “Official guidance” is not law, but inspectors expect it. “Chef Hygiene default” is a value the app checks against where no rule gives a number.

• Official guidanceFire 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).
• Official guidanceGas: 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.
• LawElectrics: the law asks for necessary inspection and maintenance (FEL, § 9) and sets no fixed interval.
• Chef Hygiene defaultHood 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.
