Abstract: At about 1:23 p.m. on March 12, 2013, an employee was working for a firm that repaired doors. He had worked for 10 years as a regular fulltime service technician for his employer. He was at a warehouse run by the big box hardware retailer Lowe's in Moreno Valley, California. He was working from an extension ladder to repair damaged dock door #230. The ladder was a Louisville Model Number FE3224 24-foot (7.3-meter) fiberglass extension ladder. He did not secure the ladder by tying it to a support before he started working from it. Company safety policy called for the ladder to be tied off. The ladder slid backward, and the employee fell approximately 16 feet (4.9 meters) to the slick concrete floor. He sustained lacerations about his body.
