July 7th was a busy day for the SAFD with multiple small jobs in the afternoon/evening hours. EN02, EN22, BT22, BT50, and BT36 worked a small grass fire that jumped a creek on them in the 2000 Blk of Escalon Ave. Then, just as I was clearing up and headed back, an Automatic Fire Alarm was upgraded to a working Box alarm at 103 9th St. Engine 4 arrived to find smoke on the 3rd floor of a hotel an requested a full High rise Box Alarm. The source of the "smoke" ended up coming from a discharged fire extinguisher that some children were apparently playing with. EN04, EN01, EN03, EN06, EN11, PL01, PL11, TK06, HR11, M06, BC06 & the Fire Shift Commander were all on the ticket. Then to round it off, Engine 32 and Tower Ladder 32 arrived to find smoke coming from the eaves and fire in the walls of a 3 story, 16 unit apartment complex off Eckhert Rd. Crews worked for almost two hours checking for extension and chasing fire. Companies on the ticker were EN32, EN42, EN37, EN49, PL32, TK37, BC04 and the Fire Shift Commander
