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.



NFPA 80 Task Force

Members of the Guardian team were in New Orleans November 13 – 14 at the National Fire Protection Association’s Task Force on field labeling provisions in NFPA 80. At NFPA’s invitation, Guardian contributed to the Public Input response to their first draft of proposed revisions to NFPA 80 as it relates to field labeling services. Guardian will continue to advocate for changes that focus on safety and proper training for field technicians.

DHI ConNextions Conference

Thank you to everyone who stopped by our booth at conNextions in Cleveland and to those who attended our conference session “The New Face of Field Labeling Service.” The audience earned one CEU credit for participating in a Q & A panel discussion of on-site inspection and evaluation of fire doors and applying appropriate time-rated fire labels. It was a great opportunity for Guardian to share information with leaders in the industry.
