Section R. 408.41837 - Definitions; FRule 1837.
(1) "Fire alarm signaling system" means an alerting signal that is clearly audible throughout all areas and which would immediately alert employees in case of an emergency.(2) "Fire brigade" means an organized group of employees that are knowledgeable, trained, and skilled in the safe evacuation of employees during emergency situations and in assisting in fire fighting operations.(3) "Fire fighting equipment" means any of the following: (a) Portable extinguishers.(b) Fixed fire equipment.(c) Water barrels and pails.(4) "Fire protection" means to provide fire fighting equipment, training, and evacuation plans.(5) "Fire resistance" means that quality of a material that renders it so resistant to fire that, for a specified time and under conditions of a standard heat intensity, the material will not fail structurally and will not permit the side away from the fire to become hotter than a specified temperature. For purposes of this part, fire resistance shall be determined by the fire test of building construction and materials, as prescribed in The National Fire Protection Association Standard NFPA 251, "Standard Methods Of Fire Testing Of Building Construction And Materials," 1990 edition, which is adopted by reference in R 408.41802.(6) "Fixed fire equipment" means a fire extinguishing system that is permanently mounted and portable portions of a system, such as a hose and nozzle attached to a fixed supply of extinguishing agent.(7) "Flammable" means to ignite easily and burn intensely or means to have a rapid rate of flame spread.(8) "Flammable liquid" means any liquid having a vapor pressure not exceeding 40 pounds per square inch (absolute) at 100 oF (37.8 oC) and having a flashpoint at or below 199.4 oF (93 oC). Flammable liquids are divided into the following categories: (a) Category 1 shall include liquids having flashpoints below 73.4 oF (23 oC) and having a boiling point at or below 95 oF (35 oC).(b) Category 2 shall include liquids having flashpoints below 73.4 oF (23 oC) and having a boiling point above 95 oF (35 oC).(c) Category 3 shall include liquids having flashpoints at or above 73.4 oF (23 oC) and at or below 140 oF (60 oC).(d) Category 4 shall include liquids having flashpoints above 140 oF (60 oC) and at or below 199.4 oF (93 oC).(9) "Flash point of the liquid" means the temperature at which it gives off vapor sufficient to form an ignitable mixture with the air near the surface of the liquid within the vessel used as determined by appropriate test procedure and apparatus as follows: (a) The flashpoint of liquids having a viscosity less than 45 Saybolt Universal Second(s) at 100 oF (37.8 oC) and a flashpoint below 175 oF (79.4 oC) shall be determined in accordance with ASTM D56 "Standard Test Method for Flash Point by Tag Closed Cup Tester," 1969 edition, as adopted by reference in R 408.41802, or an equivalent method as defined in Construction Safety Standard Part 42 "Hazard Communication," Appendix B, as referenced in R 408.41802.(b) The flashpoints of liquids having a viscosity of 45 Saybolt Universal Second(s) or more at 175 oF (79.4 oC) or higher shall be determined in accordance with ASTM D93 "Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester," 1969 edition, as adopted by reference in R 408.41802, or an equivalent method as defined in Construction Safety Standard Part 42 "Hazard Communication," Appendix B, as referenced in R 408.41802.Mich.
