How can you prevent accidents at work? One thing to remember is that it's not always the employees that are causing the accident: "Although it is clear that individual behavior influences accidents, starting and ending one's investigation at this level ignores the broader contextual influence on behavior in organizations." Certainly, screening out or firing impulsive employees will reduce the incidence of unsafe behaviors, as will mopping up oil spills and placing guardrails around machines. However (as noted previously), psychological factors such as reducing stress and pressure are important, too, and must be addressed if accidents are to be prevented. In practice, there is usually no one single cause-whether acts or conditions-of workplace injuries; instead, accident causes tend to be multifaceted.
