"I was impressed with the prompt service from Hedrick Fire Protection Idaho during my 6 Year Inspection in Rexburg. The technicians were not only knowledgeable but also conducted themselves with great professionalism throughout the process. They clearly explained everything I needed to know, which gave me confidence in their work. Knowing that my property and assets are now better protected is a huge relief. As the owner of my business, I appreciate the peace of mind that comes from their expertise. This experience exceeded my expectations, and I’m grateful for their assistance."

Frequently Asked Questions

NFPA 10 requires stored-pressure extinguishers to undergo a 6-year maintenance service, where the unit is emptied, internally examined, and recharged.

The technician fully discharges the agent, examines the interior for corrosion or pitting, disassembles the valve, replaces worn parts, seals, and o-rings, refills the agent, re-pressurizes the unit, and applies a new 6-year collar and dated tag.

A licensed technician performs the 6-year service on-site as part of Hedrick Fire Protection's mobile service.

It specifically applies to stored-pressure dry chemical and certain other stored-pressure portable fire extinguishers requiring internal examinations.

The service follows NFPA 10, the National Fire Protection Association standard for portable fire extinguishers.

Each unit receives a physical 6-year verification collar, a dated service tag, and an updated written service record for your compliance files.

On-site 6-year maintenance services are provided throughout Southeast Idaho.

If internal corrosion, pitting, or structural damage is found, the unit is removed from service and replaced or hydro-tested depending on compliance requirements.
