Andrew Ellison

Principal Engineer & Practice Group Leader

Andrew is a licensed Professional Engineer in multiple jurisdictions throughout the United States. Andrew is also trained and experienced in performing fire origin and cause investigations, and is a Certified Fire and Explosion Investigator.


Andrew applies engineering principles to the analysis of fire and explosion incidents and fire protection system failures. His past experience includes analyzing and interpreting codes and standards, inspecting systems to identify failure modes, and performing experiments to evaluate cause hypotheses. Andrew’s specific experience includes investigation of incidents involving fire sprinkler systems, wet and dry chemical suppression systems (including
kitchen systems), foam and water deluge systems, and fire detection and alarms.


In addition to fire protection engineering investigations, Andrew also utilizes his background in mechanical engineering to investigate losses involving propane and natural gas piping systems, including leaks, fires, explosions, and carbon monoxide exposures. Additionally, he has experience investigating losses associated with boilers and furnaces, and other HVAC-related equipment. Andrew also has significant experience investigating fires caused by lightning. Andrew’s project work has involved investigations nationwide in residential,
commercial, and industrial occupancies, and ranged in loss size from small single-dwelling structures to very large losses involving multiple buildings.

Andrew is also a Firefighter/Lieutenant on the Hamilton, MA fire department, where he has provided services as a firefighter and EMT since 2000. Andrew also acts as a specialty instructor for the New Hampshire State Firefighting Academy. Andrew’s unique skills allow
him to pair an engineering-level understanding of fire dynamics with hand-on fire suppression experience.
