A room heater with an outer jacket surrounding the heat exchanger, arranged with openings at top and bottom so that air circulates between the heat exchanger and the outer jacket.
Industry:Fire safety
A room heater designed to transfer heat primarily by direct radiation.
Industry:Fire safety
A room having a volume equal to at least 12 times the total volume of a furnace and at least 16 times the total volume of a boiler. The total volume of the furnace or boiler is determined from the exterior dimensions and is to include a fan compartment and burner vestibule, where used. Where the actual ceiling height of a room is greater than 8 ft (2. 44 m), the volume of the room is to be figured on the basis of a ceiling height of 8 ft (2. 44 m).
Industry:Fire safety
A roofed or covered common pedestrian area within a mall building that serves as access for two or more tenants and does not exceed three levels that are open to each other.
Industry:Fire safety
A rocket vehicle that (1) is propelled by one or more high power rocket motors; or (2) is propelled by a combination of model rocket motors having an installed total impulse of more than 320 N-sec (71. 9 lb-sec); or (3) is propelled by a combination of model rocket motors having more than a total of 125 g (4. 4 oz) of propellant weight; or (4) weighs more than 1500 g (53 oz) with motor(s) installed.
Industry:Fire safety
A rocket that (1) weighs no more than 1500 g (53 oz) with motors installed; and (2) is propelled by one or more model rocket motors having an installed total impulse of no more than 320 N-sec (71. 9 lb-sec); and (3) contains no more than a total of 125 g (4. 4 oz) of propellant weight.
Industry:Fire safety
A rocket motor in which one or more of the fuels exist in a physical state (solid, liquid, or gaseous) different than the oxidizer and that derives its force or thrust from the combination thereof.
Industry:Fire safety
A rocket motor that has more than 160 N-sec (36 lb-sec) but no more than 40,960 N-sec (9208 lb-sec) of total impulse, or that produces an average thrust of greater than 80 N (18 lbf), or that contains greater than 62. 5 g (2. 2 oz) of propellant.
Industry:Fire safety
A rocket motor that has been designed and manufactured so that the user can load, reload, and reuse the pressure-containing body or casing using the parts and components of a motor-reloading kit.
Industry:Fire safety
A rocket motor that has a total impulse of no greater than 160 N-sec (36 lb-sec), an average thrust of no greater than 80 N (18 lbf), and a propellant weight of no greater than 62. 5 g (2. 2 oz), and that otherwise meets the other requirements set forth in NFPA 1125, CodefortheManufactureofModelRocketandHighPowerRocketMotors.
