  • Page 9: Chapter 1 General Information

    General Information CHAPTER 1 GENERAL INFORMATION INTRODUCTION This document is provided to instruct and familiarize the owner with the Kidde Fire Systems ™ Natura Inert Gas Fire Suppression System (Natura IGS system) with IG-100, IG-541, IG-55, or IG-01 or IG-55 (herein refer to collectively as the “Agent”). This manual covers: •...

  • Page 10: Safe Cylinder Handling Procedures

    Before handling Natura IGS products, all personnel must be trained in the safe handling of the containers as well as in the proper procedures for installation, removal, filling, and connection of other critical devices, such as flex hoses;...

  • Page 11: About The System

    Natura IGS agents are used at relatively high concentrations to extinguish fires, typically in the range of 40 to 50% agent in air, or more. At a Natura IGS agent concentration of 45%, the residual oxygen concentration is 11.5%, compared with 21% in normal air. The principal health risk from exposure to atmospheres having such low oxygen concentrations is "hypoxia,"...
  • Page 12 Note: The term "…sea level equivalent of oxygen…," used above, deserves some clarification. The allowed exposure limit to air diluted with Natura IGS agents relates to the residual oxygen concentration. At sea level the atmospheric pressure is 14.7 psi (101,325 Pa).
