passage: By Associated Press PUBLISHED: 14:12 EST, 19 March 2014 | UPDATED: 16:54 EST, 19 March 2014 A University of California at Irvine study shows that titanium-coated golf clubs can cause fires in course-side vegetation Golfers are urged to swing with care after scientists proved that titanium-coated clubs can cause course-side vegetation to burst into flames. Scientists at the University of California, Irvine, proved that titanium-coated clubs can cause sparks that ignite vegetation. Orange County Fire Authority Capt. Steve Concialdi said Wednesday that the results confirm a suspicion investigators have had for years - that titanium alloy clubs were the cause of at least two blazes on area golf courses.
