Fire Extinguishers

Specialized dry powder suppression for machine shops, aerospace facilities, and labs. We offer expert NFPA 10 certified inspections, tagging, and recharging in Albuquerque.

Specialist Dry Powder for High-Temperature Metal Hazards

Class D fire hazards involve combustible metals such as magnesium, sodium, potassium, titanium, zirconium, lithium, and uranium. When these metals ignite, they burn at extremely high temperatures (often exceeding 2,000°F) and react violently with water, carbon dioxide, or standard dry chemicals. Class D extinguishers contain specialized dry powder agent (such as sodium chloride or copper-based mixes) that works by:

  • Smothering & Crust Formation: The powder melts slightly under intense heat, creating a physical crust that seals the burning metal from oxygen.
  • Heat Absorption: The specialized compound acts as a thermal sink, drawing heat out of the metal to reduce temperature.

Class D extinguishers are highly specialized and required in facilities that cut, mill, or grind reactive metals. FSI New Mexico helps Albuquerque machine shops, aerospace contractors, and research labs remain fully compliant with NFPA 10 and OSHA safety rules through certified inspections and tag re-certifications.

Critical Warning: NEVER use water, foam, CO₂, or standard ABC dry chemical extinguishers on a metal fire. Water will dissociate into hydrogen gas, causing a violent explosion and spreading the fire rapidly.
