The overall technique of using the Tundra™ Fire Extinguishing Spray is similar to that of a traditional fire extinguisher. Aim the Tundra™ at the base of the fire and sweep from side to side at the bottom of the flames. One of the key advantages of the First Alert® Tundra™ Fire Extinguishing Spray is its ease of use and intuitive design, providing consumers quicker response time in the event of a fire. Unlike traditional fire extinguishers, the First Alert® Tundra™ Fire Extinguishing Spray can be operated with one hand vs. two, providing the user more control.
