Negligent Hospital Security Expert Witness

Florida | Nationwide | Mark J. Lang, MCJ, CPP, CHPA — Former Executive Director of Security, Orlando Health

​

Hospitals are legally and ethically obligated to provide a safe environment for patients, visitors, and staff. When that duty fails — through inadequate security staffing, broken cameras, poor lighting, uncontrolled access, or the failure to respond to foreseeable violence — the consequences can be devastating and the legal liability significant.

Investigations HQ, LLC, led by Mark J. Lang, provides authoritative expert witness services in negligent hospital security litigation. As a Certified Healthcare Protection Administrator (CHPA) — the highest credential in healthcare security — and the former Executive Senior Director of Security Operations for Orlando Health, Mr. Lang brings a level of firsthand institutional knowledge that few experts nationwide can match.

​

What Is Negligent Hospital Security?

Negligent hospital security occurs when a healthcare facility fails to implement reasonable, industry-standard security measures to protect those on its premises. Courts and juries examine whether the harm that occurred was foreseeable and whether the facility acted reasonably to prevent it.
 

Common forms of negligence in hospital security include:

• Inadequate security officer staffing levels or training

• Failure to control access to restricted areas (emergency departments, patient rooms, ICUs)

• Non-functioning or improperly positioned CCTV surveillance systems

• Absence of panic buttons, duress alarms, or communication protocols

• Poor lighting in parking structures, stairwells, and exterior walkways

• Failure to implement or follow a workplace violence prevention program

• Ignoring prior incidents or threat reports involving the same patient or visitor

• Inadequate response protocols to de-escalate or contain violent incidents
