Finnish rescue authorities are issuing warnings about fire risks associated with Midsummer sauna traditions. The Finnish Rescue Services Centre (Spek) and Helsinki Metropolitan Area Environment Services (HSY) advise moderation when heating saunas and grills during the holiday. Specifically, they caution against excessive use of firewood, as overheating can damage fireplaces and chimneys, potentially leading to fires. Regulations on firewood quantities may be lower than some realize. Experts emphasize that responsible heating practices are crucial for a safe Midsummer celebration. The warnings aim to prevent incidents stemming from improper sauna and grilling habits during the busy holiday period.
