Lucky Stores, Inc., owned a building with a large sign spelling out “ARDENS” on it. Lucky hired Q.R.I. Corporation as an independent contractor to remove the sign. The removal work was inherently dangerous because each letter was about six-feet high and two and one-half feet wide and weighed between fifty and sixty pounds. Q.R.I. workers safely removed the letter “A” and loaded it on their truck. They also safely removed the letter “R” and leaned it against the truck. Then, for a moment, one worker negligently released his hold on the letter. A gust of wind blew the letter into contact with 79-year-old Smith, injuring her seriously. Is Lucky liable to Smith for damages? (Smith v. Lucky Stores, Inc., 61 Cal. App. 3d 826, 132 Cal. Rptr. 628)
