The Society for Human Resource Management (SHRM), "best practices" for workplace violence prevention policy, says that any potentially dangerous situations must be immediately reported to a supervisor or the human resource (HR) department. Reports can be made anonymously, and all reported incidents will be investigated.

Discussing weapons or bringing weapons to the workplace
Displaying overt signs of extreme stress, resentment, hostility, or anger
Making threatening remarks or acting in an aggressive manner
Showing sudden or significant deterioration of performance
Displaying irrational or inappropriate behavior, including sexual harassment
Bullying, harassing, or acting abusive towards co-workers
