Kitchener, Ontario fire dispatch toned out St Clements and Wellesley for a confirmed structure fire at 3482 Hessen Strasse at 14:55. The St Clements district chief asked for details on the call and requested a second alarm, a full response from Linwood. Shop workers were using a blow torch to remove some metal fixtures from the wall. They noticed smoke coming from the walls and evacuated the sand blasting business and called 911. St Clements arrived on scene reporting smoke showing. Water was initially used from tankers, and then a 4” line was dropped from a fire department 50,000 gallon cistern located 600 feet down the laneway. The fire was contained to the wall and a small portion of the attic. Overhaul took 2.5 hours pulling the siding down, and clearing cellulose insulation from the attic. Photos taken 30 minutes into the call. Box 690 provided rehab.
