Firefighters, above, spray water on a burning pile of magnesium Monday at Scrap-All Inc. in Ybor City. The fire started by accident about 11 a.m. at the scrap yard, 2801 E Fourth Ave., when a welder was cutting pieces of aluminum, according to Tampa fire Chief Bruce Savage. Magnesium is highly flammable and makes an intense white light when it burns. Firefighters could only pour water on the 200-pound pile of magnesium and wait for the fire to die out. No injuries were reported, and property damage was not significant, officials say.
