Forklifts account for thousands of serious injuries and dozens of deaths each year in North American workplaces. According to statistics reported to government inspectors by employers, every year 100 workers are killed and 20,000 seriously injured in forklift related accidents. Many more have sustained severe, life long injuries. Many accidents are due to overloading. Employers eager to increase efficiency at the expense of safety, encourage excess loads which can cause the forklift to tip over. In other cases workers are crushed when load limits are exceeded and materials fall.
