At approximately 1830hrs E834 was dispatched as the third-due engine for an apartment fire on the 5400 block of 16th Ave, in company 44′s area. Units arrived at a garden apartment operated to find fire throughout the cockloft. The below-freezing weather conditions caused hydrants to freeze, forcing E834 to supply the first due wagon and also complete their third due responsibilities. The fire was quickly knocked using multiple engine and truck companies. All searches were negative.
