Question about flammability

According to the page: When burned, ETFE releases hydrofluoric acid, which is extremely corrosive. but also: Another key use of ETFE is for the covering of electrical wiring used in high stress, low fume toxicity and high reliability situations. Aircraft wiring is a primary example.

Why would a substance that burns with corrosive toxic fumes be used in a low fume toxicity application? Are there reference sources for these two statements, please?
