Combustible Liquid A liquid with a flash point ABOVE 100F
If the current flowing out from an electrical panel is 12.5 amps, and it then flows
12.5 through an electrical load of 1500 watts, what is the amperage of the remaining
current flow of the return circuit?
If a hair dryer draws 8.3amps (in a home with 120-volt service), what is the wattage?
1000
*Power (P) = current (I) x voltage (V)
Watts = amps x volts

1.5 times
*That is, the distance from the furthest debris
1100°F What temperature in the upper gas layer causes the onset of Flashover?
1960°F The temperature at which copper melts
The measurement of the radiant heat flux (from gas layer to the floor) that indicates
2 W/cm2
the onset of flashover
The voltage between the two hot wires at the service entrance cables in most single-
240 volts

3 years The revision cycle for NFPA 921 (timespan)
350°F The flash point of power steering fluid
In high-pressure fuel-injected vehicles, this is the typical range of pressure that is
35-70 p.s.i.
used to pump fuel from a fuel tank
5 and 17 The lower explosive and upper explosive limit of natural gas (methane)?
