My father used to change engine instrument senders on KC-135 and KC-97
aircraft, outside during winter nights, while stationed at Thule AFB
in Greenland. Wearing gloves isn't possible while doing this.

It didn't matter how much it cost to heat the atmosphere during those
repairs. G

I think it would be difficult to splice a fiber optics cable (human hair
diameter) wearing gloves as well.

When we use salamander/torpedo heaters the unit is kept outdoors and the
heat directed as needed into a well ventilated area. An example would
be setting the unit about 5' outside an wide open garage door with the
heat directed inside the garage.

When working in enclosed areas (manholes) we use portable propane
heaters that have a heat exchanger and work in conjunction with manhole
blowers to direct the heat.
