The Guardian name is respected by all major accreditation boards and Authorities Having Jurisdiction (AHJs).


Guardian Fire Testing Laboratories, Inc. was created in 1994 by Joe Pearson and Lalit Kumar – both coming from engineering backgrounds. Since our formation, the world of fire testing has changed frequently and dramatically. At each shift, Guardian has embraced the technological advancements and revised requirements to deliver optimal service to our customers.

While our industry has evolved over the past 25 years, what has remained steadfast is the way we conduct business. To this day, Guardian remains a family-run company, with direct ties back to our founders within our current management group.

We had the opportunity to meet State Fire Marshalls from all over the country as well as other professionals from the fire prevention and safety field. Many thanks to NASFM for having us at such an important industry event. It was a great show and we plan to be back next year and beyond!

We Never Stop Learning

Guardian is in the business of keeping people safe, whether they are patients in a hospital, residents of apartment complex or shoppers at the mall.  Building codes and fire safety regulations can change over time, by industry or by local jurisdiction. It is essential that we stay on top of current fire door safety requirements regardless of industry or location.

Our team recently attended the American Society for Health Care Engineering (ASHE) Annual Conference. At ASHE we discussed fire door/frame compliance with key partners in the healthcare industry. Thank you to those who stopped by our booth to share their knowledge and experience; and congratulation to Rick Tinsley from Tennessee Healthcare Engineering Association who won our prize drawing for a $200 VISA gift card.

Back from NFPA

Last week, Dan Brandel, our Lab Testing Engineer and Mike Thorp, one of our Field Labeling Technicians returned from the National Fire Protection Association Conference and Expo in Boston.  Guardian sent the two technical experts to keep up to date with the latest fire safety technology and standards.  Mike, who was recently appointed to the NFPA 80 Technical Team, had the opportunity to meet with some of his colleagues to share information and learn from each other.

Guardian would like to thank NFPA for hosting this event and we look forward to working with the great people we met in the future.

What we do Matters. It can Save Lives.

On January 11, 2022, seventeen people were killed when a fire broke out in a high-rise in the Bronx. Investigators concluded that fire safety doors failed. This tragedy should not have happened.

Having properly rated and labeled fire doors and frames can save lives and property. Fire doors must be labeled with the appropriate time-rated flame and smoke spread rating. Fire-rated doors, assemblies and hardware are required for life safety compliance in apartment buildings and most other residential (nursing homes, dormitories, etc.) and non-residential (schools, hospitals, hotels) facilities.

We understand the critical importance of Fire Safety Doors. It’s why we do what we do. Contact Guardian today for a complimentary consultation.
