​

Workplace violence is the third leading cause of fatal occupational injuries in the United States, according to OSHA — and every employer, under federal and state law, has a duty to provide a workplace free from recognized hazards that cause or are likely to cause serious harm. When that duty is neglected, the consequences extend from individual tragedy to significant civil liability.

​

Investigations HQ, LLC provides comprehensive workplace violence services: proactive consulting and training to help organizations prevent incidents before they occur, and expert witness and investigative services when litigation arises. Mark J. Lang, MCJ, CPP, CHPA, brings executive-level security leadership experience to every engagement, including direct experience developing and implementing workplace violence prevention programs for a major Florida health system.

​

The Five Types of Workplace Violence

OSHA and the security industry recognize five distinct typologies of workplace violence, each requiring different prevention and response strategies:

• Type 1 — Criminal Intent: Perpetrator has no legitimate relationship to the workplace (robbery, burglary)

• Type 2 — Customer/Client/Patient: Violence by those the organization serves (patient assault on healthcare worker, client attack on service provider)

• Type 3 — Worker-on-Worker: Violence between current or former employees

• Type 4 — Intimate Partner: Domestic violence that enters the workplace, targeting an employee

• Type 5 — Ideological Violence: Terrorism or extremist-motivated attacks targeting an organization

Effective prevention requires understanding which typologies present the greatest risk in a given workplace environment — and implementing controls accordingly.
