Question 1

How can a law firm find an emergency communications and 911 expert witness for litigation?

Accepted Answer

A law firm can find an emergency communications and 911 expert witness by searching directories that categorize experts by specialty, such as PSAP operations, dispatch, or NG911 technology. Counsel typically filters candidates by law enforcement, fire, EMS, or telecommunications background, years of PSAP supervisory experience, and prior expert testimony. Case-specific factors such as familiarity with local or state 911 statutes, FCC E911 rules, and NENA standards also guide selection. A qualified expert should provide a detailed curriculum vitae, sample reports, and prior case history for conflict and Daubert review.

Question 2

What does an emergency communications and 911 expert witness do in a negligent response case?

Accepted Answer

An emergency communications and 911 expert witness evaluates whether call takers and dispatchers followed applicable protocols, training, and standard operating procedures. The expert reviews 911 audio, CAD event logs, call transfer records, radio traffic, unit status data, and mapping or location information to reconstruct the communications sequence. The expert then compares actual performance to written policies, national standards, and statutory requirements to identify deviations from the standard of care. The analysis supports opinions on causation, timeliness of response, and whether any communications failures contributed to injury or death.

Question 3

In what types of lawsuits is a 911 dispatch expert witness commonly retained?

Accepted Answer

A 911 dispatch expert witness is commonly retained in wrongful death and personal injury cases alleging delayed or improper emergency response. These experts also participate in civil rights litigation under 42 U.S.C. § 1983 that involves denial of emergency services, law enforcement dispatch decisions, or failure to respond. Additional matters include police use of force incidents, fire and explosion events, school or workplace violence, medical emergencies, and major traffic collisions where dispatch information influenced outcomes. Criminal cases may also involve 911 experts for issues such as verification of call timing, caller location, or authenticity of recordings.

Question 4

What qualifications should an emergency communications and 911 expert witness have?

Accepted Answer

An emergency communications and 911 expert witness typically has substantial experience in public safety communications, such as PSAP management, dispatch supervision, or 911 system administration. Relevant certifications may include APCO or NENA training, emergency medical dispatch credentials, and specialized courses in incident command and communications technology. Many experts have prior service in law enforcement, fire service, or EMS combined with technical knowledge of CAD systems, radio systems, and NG911 infrastructure. Prior deposition and trial testimony, publications, and participation in standards committees can further support expert credibility under Daubert or Frye standards.

Question 5

What records and data does a 911 expert witness review in an investigation?

Accepted Answer

A 911 expert witness typically reviews audio recordings of emergency calls, CAD event and unit history logs, radio and telephone records, and location or mapping data such as ANI and ALI. The expert also analyzes PSAP policies and procedures, training materials, staffing schedules, and quality assurance reviews to evaluate systemic issues. When NG911 or VoIP services are involved, the expert may examine routing tables, network records, and carrier documentation related to call delivery and location. These materials allow the expert to construct a detailed timeline and determine whether communications met applicable standards.

Question 6

Can an emergency communications expert witness address both traditional 911 and NG911 systems?

Accepted Answer

An emergency communications expert witness can address both traditional wireline 911 and modern NG911 systems if the expert has relevant technical training and operational experience. Traditional systems focus on landline call routing to a PSAP with basic location data, while NG911 incorporates IP-based networks, text-to-911, multimedia, and advanced location services. Experts familiar with both environments can explain how legacy and NG911 architectures affect call delivery, location accuracy, redundancy, and system resilience. This dual expertise is important in cases involving wireless phones, VoIP services, or transitions between legacy and NG911 infrastructure.

Question 7

How does a 911 expert witness help establish the standard of care in emergency response litigation?

Accepted Answer

A 911 expert witness helps establish the standard of care by citing applicable laws, regulations, and industry standards that govern emergency communications. The expert identifies relevant state 911 statutes, FCC rules for E911, and guidelines from organizations such as NENA, APCO, and NFPA. The expert then compares these requirements and best practices with the PSAP’s written policies and actual call handling and dispatch behavior. This comparison supports opinions on whether the communications center met, exceeded, or fell below accepted professional standards in the circumstances of the case.

Question 8

What factors affect the cost of hiring an emergency communications and 911 expert witness?

Accepted Answer

The cost of hiring an emergency communications and 911 expert witness depends on the expert’s qualifications, hourly rate, and the complexity of the matter. Factors such as the volume of 911 recordings and CAD data, the need to review technical network records, and the number of parties and incidents affect total hours. Additional costs can arise from site inspections, travel, preparation of demonstrative exhibits, and time spent in deposition or trial testimony. Many experts require an initial retainer and provide written fee schedules that distinguish file review, consulting, and testimony rates.

Question 9

Can a 911 expert witness testify about PSAP staffing, training, and supervision issues?

Accepted Answer

A 911 expert witness can provide opinions about PSAP staffing levels, training programs, supervision, and quality assurance when those issues relate to alleged communications failures. The expert evaluates whether staffing met internal policies, industry guidelines, and reasonable expectations for call volume and peak demand. Training records and supervisory practices are examined to determine whether personnel were prepared to apply protocols such as emergency medical dispatch or high-risk incident procedures. These assessments can support claims involving systemic negligence or defense arguments that individual call takers acted within reasonable operational limits.
