Unsafe behaviors or decisions are usually contributing factors in incidents. Sometimes an unsafe behavior increases the severity of injuries; other times, it is simply a key determinant in causing the incident.
While employers also have a large responsibility to control hazards for their employees, the role employees play is vital. If you understand the hazards of your job and the safe behaviors required of you, and you do your part to help, many incidents can be avoided.
A successful safety program includes you being aware of the hazards of tasks, knowing the critical behaviors, and following them.
