Description:On July 29, 2004, a 40-year-old male engineering technician was struck and killed on a road-building project by a cement mixer that was traveling in reverse. The road surface was compacted aggregate and crushed limestone and had a slight incline. There were two cement mixers in the immediate vicinity. Cement mixer #1 was unloading cement into a curb-paving machine ("mule"). Cement mixer #2 had already completed unloading its cement into the mule and was being washed out by the driver. To determine if the mixer #1's concrete was within specifications, the victim took a sample that weighed approximately 600 pounds from chute and loaded the concrete into a wheelbarrow. The victim pushed the wheelbarrow past the driver side of mixer #1, and as he came to the rear of mixer #2, he turned sharply south, to his right to get to his truck. The victim's back was facing mixer #2. At approximately the same time, the driver of mixer #2 finished washing out his mixer, entered the cab, activated his backup alarms and began to move in reverse to leave the job site. See Figure 1. It appears that the victim heard the backup alarm from mixer #2 because a witness stated that he increased his pace to attempt to get out of the way of the mixer. It appears that the victim either tripped or lost control of the wheelbarrow and was struck and backed over by mixer #2. The victim was transported to a local hospital where he was declared dead. Recommendations: 1. Employers should ensure that workers on foot remain clear of moving equipment by developing and utilizing an "Internal Traffic Control Plan" for each highway and road work zone project. 2. Ensure appropriate communication methods for workers on foot and equipment operators; equipment operators should use trained spotters. 3. Review options for equipment-warning devices for both construction equipment and employees.
