Work injuries occur in every type of business and at every type of job site. Injuries can range from sprains, strains, and contusions to broken bones, spinal injuries, and nerve damage, to concussions, and may sometimes even be fatal. Still, all employers can provide a safe environment for their employees – with proper training, safety policies, and preventive measures. While each industry has its own hazards, the most dangerous occupations, according to the number of injuries reported, are agriculture, construction, transportation, and health care.
