 Flameproof Resistors v Fusible Resistors.Any Difference?

The good news is that "flameproof metal film resistors" will burn out and
open up at a rate that is fairly consistent with fusible resistors of the
same value and wattage.  Most repair shops will make the substitution on a
regular basis.  .....HOWEVER........there are some circuits that  specify
the original fusible resistor as a critical safety component and no
substitutions should be made.
Flameproof resistors are available from ECG and RCA from most electronics
jobbers and with low ohm values starting from 0.1 ohm on up in 1/4, 1/2,
1.0, and 2.0 Watts.  These same jobbers will also have many of the more
popular original equipment fusible resistors in the case of a critical
safety component replacement.

 Flameproof Resistors v Fusible Resistors.Any Difference?
Is there any difference between the two? Is a metal film resistor considered
a safe alternative to either? I have a resistor (purple colored) that I
assume is a fusible. It is 1 ohm and I believe 1/8 watt but I can't find
this in any of my catalogs.Physically, it's the same size as an 1/8 watt
carbon film resistor, but are fusible's rated any differently? Most of my
catalogs list 1 ohm at 1/4 watt or their 1/8 watt resistors start at 10
ohms. Anybody know of a source? Well that's enough questions. Thanks.
